But Zhang Manager Zhang took the car and boarded the canal ship from Yangzhou and headed north. The result of the negotiation with Li Bin had sent someone to notify the person in charge of Suzhou!

Of course it is okay for the Duke and the butler to take a private boat. The reason why Manager Zhang is so anxious is that he is attracted by the carriage transaction!

When Li Bin asked him to pull the car and try it, he was still unhappy and reluctantly got on his hand. His face was silent, but he was shocked: Can such a heavy car be easily dragged by one person?

As a car owner, he knows very well what this means! A car that originally required two horses to pull, but now one horse may run faster. A car could only pull seven hundred kilograms, but now a car might pull two thousand kilograms!

If the Duke's family can do this business, it will be a lot of money! Even the military can't handle the orders!

How could Zhang Manager Zhang, who is doing old business, not telling that this car was a waste of money by Li Bin. He replaced the wheels with wooden boards, and removed all the messy inside. The whole car was fine without any money!

In this era, traveling far away is a gambler. There is a four-wheeler that can sleep while lying down, and at least all officials will buy it!

If the Duke’s Mansion is not strict with its strict rules, how could he be honest in doing business with Li Bin!

I can’t buy it and copy it if I don’t rush it! Manager Zhang sat on the boat and even praised his wit!

The Duke’s Mansion can imitate Li Bin, but others dare not imitate the Duke’s Mansion. At that time, it will be the only business in the north, so you won’t have to be cut by that Li Bin!

"Master, the second housekeeper has returned from Jiangnan and brought three cars, saying that he has something to discuss with you!"

British Duke Zhang Zhiji was stunned for a moment: "Car? What kind of car!"

"The second butler said you would come over and see it in person!"

Zhang Jiangui is an old man from the Zhang family and can't do anything without any restraint. Zhang Zhiji came to the front yard and looked up and saw three four-wheeled carriages parked in the yard. Zhang Jiangui was waiting in front of the car!

"Why did you come back so quickly to Jiangnan? You didn't even have a rest on the way?"

The elderly at home, can you care or care?

"Master Xie is concerned. This time I went to Jiangnan to talk to Li Bin very smoothly, so I came back soon!"

"Oh, have you got the North's franchise?"

"Yes, I guarantee to order 100,000 taels per month, and he also gave a 20% discount. He said that he was busy with affairs and could not come to meet the master, so he would just give him a small gift first!"

Zhang Zhiji saw that his face was so effective, and of course he was in a good mood: "This guy is good at being a human being, the master remembers it! Then how did you come from bringing these three cars?"

When Zhang Manager Zhang saw that he asked about the car, he was not sleepy at that time and felt it was worth it all the way.

Immediately repeating what Li Bin said to him to Zhang Zhiji.

What are the ergonomic lambskin seats, steel axles, spring shock absorption, eighty-eight processes of mahogany carriages, fifty-three repeated polishing, the paint is dried by ultraviolet rays, and the gold thread on the carriage was drawn in one stroke by the master of art in thirty years of experience!

Just scraped off this line and wanted to make up for it. Five hundred taels of silver is not a double price! The door-to-door service fee is not counted!

The singular brag made the prince a little weak, and he felt like he was going to be a long life when he was riding in this car!

"stop!"

Zhang Zhiji quickly shouted to stop: "This car looks good, can it turn? How about sitting?"

Manager Zhang quickly helped the Duke into the car and ordered the servant to bring a horse over!

Zhang Zhiji quickly reminded: "How can one horse be enough for such a big car? Add another one!"

Shopkeeper Zhang said quickly, "No, no, this car is very lightweight to pull, it's enough to use a horse first!"

Zhang Zhiji saw that he insisted, so he tried it in the yard without fear of losing face to the Duke's Mansion!

As soon as the car started running, Zhang Zhiji felt the difference, there was no sound! It was particularly stable!

And it’s effortless to turn around, and it’s easy to turn!

He asked casually about the price and sighed: "This money is worth spending! I bought too little! I should buy a few more cars at home to give it to others!"

When the shopkeeper Zhang heard that there was a chance, he quickly told the Duke about his plan in detail!

A plan made the Duke's eyes brighter and brighter: "It's worthy of being Mr. Zhang, this time the matter is done well! I see that the imitation carriage is left to your second son to do it! If you have time, teach him more!"

When Manager Zhang heard this, he was overjoyed. There was no better reward for being a servant than giving a future. It seemed that this time the matter was done very well!

If Li Bin knew that Manager Zhang was making a copycat, he would have to laugh three times! Slowly imitate you! I will lose if I can copy half of it!

He is busy watching the welder weld the boiler now!

Now the ones that limit his power are not the steam turbines and generators, but the pressure cooker! The efficiency is too low. Lao Wang, a master of casting, also said that he could not do it even bigger. After all, it is too difficult to cast a pressure cooker that is several meters high!

Now the electric welding machine is barely available, and high manganese steel pipes are available, so Li Bin asked them to start building fire tube boilers!

This thing relies on hot air to heat up the pipe, and the efficiency is improved and the pressure is increased. It is many times stronger than his pressure cooker! It is just that there are a lot of pipes!

Four welders bumped and welded for four or five days before they finished!

Li Bin was muttering in his heart: Is it a bit like I'm trying to make a novice weld a pressure vessel?

Put the water in and put it overnight. When you wake up in the morning, check that there is no leakage. Turn off the pressure reducing valve!

The design pressure is 1.6mpa. Li Bin is preparing to pressurize to 3mpa. If it doesn’t explode, it will be considered passing!

For safety, Li Bin also specially designed an electric coal mixer! The conveyor belt conveys the coal to the crusher, and then blows it into the furnace with a blower!

Li Bin asked everyone to retreat far away and use his telescope to look at the barometer on the boiler! This is the product brought by the 21st century and it is reliable!

He is now looking for watchmakers everywhere and is ready to start researching instruments by himself!

2mpa has not exploded, it seems that there is no big problem! 2.4mpa has not exploded yet, so it is stable!

"boom!"

Like a bomb, the entire boiler exploded in an instant, and the water at more than 200 degrees was directly vaporized, and the entire scene was filled with smoke!

It seems that the goddess of luck has not favored Li Bin and has to start over!

The four welders were trembling. They never thought that the thing they were welding would explode like this!

The boiler workers who used to burn pressure cookers had bad looks! Who would have thought that they would not feel good when they stood in front of bombs every day!

Fortunately, the pressure cooker made by Lao Wang is quite reliable and has never exploded. Otherwise, Li Bin would have to use orders to find a boiler!

It seems that I have to explain the function of the pressure reducing valve to them later in the last class!

Ask the welders to find all the textbooks and start looking for the reasons for the cracks first! First list the possibilities, and then let them tell them how to avoid them!

The on-site meeting has been held for one day, and we will start over tomorrow!

Li Bin thought to himself! Now he is only two or three MPAs, so what should I do if I do urea 20 MPA later? I’m worried!

No matter how worried you are, you have to do it. This time, the four welders were so serious that they moved Li Bin so much that they wanted to give them a bonus!

These four welders were also frightened! Li Bin's plates were so big, and they were all black workshops that were built by civilized methods, so there was almost no safety protection!

But there has never been a death accident until now! In other words, there were a few people who broke their fingers and hit their feet. Li Bin treated them all for free according to the regulations, then compensated them, and arranged a job within his capacity!

Yesterday, the efforts of so many people were blown into scrap iron. Li Bin did not scold them, but instead helped them find the defects and analyze the reasons!

If the boiler they welded would kill people, they would not be able to get through it themselves!

Seeing them working hard to weld, Li Bin secretly cursed himself for being so stupid! He brought a lot of metal-related instruments, but he didn't remember anything, but he actually forgot the flaw detector!

I didn’t do this job in my previous life. I was still looking at these instruments and asked the store owner who recommended the metal processing instruments!

He bought all the lightweight ones! He kept them all in the warehouse! He had to sort them out if he had time!

It was completed again four days later. This time Li Bin remembered his black technology, so he quickly took out the flaw detector and started operating according to the instructions!

The four welders were confused and didn't understand what he was doing! When Li Bin saw that they were good at using this thing, he might as well just check and teach!

The five people spent another day checking all the welds, and this time there was no trouble!

After testing again, the pressure was directly to 3mpa. Li Bin turned off the coal delivery machine and waited for the pressure to drop! He was glad that the instrument did not lie to me!

To be on the safe side, Li Bin asked the four welders to use the flaw detector to check the boiler again to see if there were any hidden injuries after the pressure was just raised, and asked them to review the use of the instrument!

Cultivating talents is more useful than building a boiler!

In the Ming Dynasty, were welders still afraid of changing jobs? It was a joke!

The boiler has passed the test. I believe that with the flaw detector, the welder's technology will improve quickly! Li Bin stuffed eight apprentices to them in one breath, and he will practice it on their own in the future!

With the fire tube boiler, Li Bin can finally remove the other five pressure cookers, saving a lot of coal money every day!

Now Li Bin is organizing everyone to upgrade and transform the machinery and equipment and try to optimize it!

Isn’t industrial technology just a little bit of progress?

"Old Zhao, can it be done?"

Li Bin asked about the stonemason team leader Zhao Jian, who was carrying someone to make a base for Li Bin's big treasure, a four-meter-long lathe!

This medium-sized lathe weighs about 7 tons and the base is a piece of pig iron that is almost four tons. Li Bin can only dismantle the work part and use granite as the base here so that there is no need to spend three or four years to do the time-saving treatment!

The stone was a large piece of Jinan Qing that he bought with a merchant. It cost him ten thousand taels of this five or four meters long stone!

The specifications he requested were too big, and it was a lot of effort for transportation!

When Zhao Jian heard his question, he looked bitter: "It's ok, but this stone is too hard and can't bite it!"

Li Bin picked up the tool next to him and tried it. This was the tool brought by the craftsmen themselves. The intensity was too poor, and it was still slow to continue like this!

Li Bin’s chin: “Forget it, I’ll make a mill for you before processing. You can draw the size first!”

Li Bin thought of making a gantry for them, installing a motor to drive the grinding wheel, and pushing the motor directly to polish the stones!

Li Bin also wanted to make handheld power tools, but unfortunately the technology was not up to standard. The power was too small and the power was not large enough. It was probably not possible to polish the stones, so he could only hang them with a gantry first!

After seeing this drawing, Lao Wang from the machinery factory immediately put forward his opinion: "Young master, can we make this one in the factory to hang crucibles? This way it is safe and convenient to cast!"

Li Bin laughed: "Good idea, not only should it be found in the factory, but also in the dock in the future! Try to make it bigger, the castings will probably get bigger and bigger in the future, but it won't work if they are small!"

This is the shipbuilding artifact gantry crane! There is no foot in the factory, just a cart!

So only enough people can come up with enough good ideas!
Chapter completed!
