Chapter 387: Clay Membrane Casting
The head of the gunsmith shouted loudly about the apprentice, as if this was the only way to show his status and express himself in front of the industrial Hou Zhu Shun: "You two are still stupid, why don't you hurry up and erect the clay mold." ”
"And you! Hurry up and find some soft materials, it's going to burn wax soon, it's stupid, I'm standing there, how did you accept such an idiot. ”
These apprentices were the children of workers in various steam factories, and their parents earned some money and sent their children to the new school for a few years to complete literacy.
The mastery of all kinds of new machinery of the Daming Arms Company is much faster than that of those apprentices who have not studied at the beginning, and it only takes a few months to become a skilled worker.
Those apprentices who have not studied need three years in a short time, and even now they still can't operate the new machinery, and have been serving as junior apprentices with the least amount of money.
This is the reason why Song Yingxing insisted that the workers send their children to the new-style school, and when he encountered some workers who stubbornly believed that literacy was useless, it was better to enter the steam factory early, and he would personally go to persuade them.
Entering a new school is not necessarily about how much knowledge you can learn, but the most important thing is to enlighten and enlighten your children.
The apprentices selected by the manager of the cannon casting workshop are all senior apprentices, and they will be able to become craftsmen on their own in a year or two.
For the apprentices who were familiar with the Ming cannon casting method, they were originally very nervous in front of Zhu Shun, and when they heard the shouting of the gunsmith's head, they suddenly got in a hurry and almost knocked down the mud mold.
This made the face of the gunsmith suddenly ugly, and as the manager of the cannon foundry workshop, he was about to stretch out his face and slap an apprentice in the face as usual.
Zhu Shun frowned and said, "Doumi, the workers have learned to engage in privileges. ”
Zhao Doumi, who was standing on the side with a large square, was suddenly a little embarrassed, standing in place and not knowing what to say.
The manager of the cannon casting workshop, who has been accompanying him, is a student of the Beijing Normal University Hall, and the Daming Arms Company, like other steam factories, is supported by the students of the Beijing Normal University Hall.
This student of Beijing Normal University spent most of his time on the study of airtight cannon latches, and as long as the craftsmen completed their share as required every month, they rarely bothered about the affairs of the cannon casting workshop.
The students of Jingshi University didn't expect that this brother Lian Zong, who was not confused about his age, would make him lose face in front of the most respected mountain chief, and his face was also ugly: "Shut up, hurry up and demonstrate the cannon casting method of the Ming Dynasty." ”
After the gunsmith head kept yelling five and six, Mei Zizi, who felt good about herself, thought about showing her face in front of the industrial marquis, but she couldn't figure it out in exchange for the scolding of the Lian Zong brothers.
I thought that the apprentices' hurried hands had angered the industrial marquis, and a wave of anger immediately rose in my heart, thinking that when the industrial marquis left, you would look good here.
This gunsmith who relied on the old man who could only cast cannons by the local method was transferred to the transport team and became a coolie transporting cannons before he had time to pack up a few apprentices after Zhu Shun left.
In the past, because of the high money and status brought by the gunsmith's head, not to mention, the captain of the convoy was still the father of an apprentice, and he had long wanted to clean him up, but he never had a chance.
The head of the cannon caster, who did not have a few incense sticks and lived a good life, did not dare to slack off, and personally went over to burn the fire to demonstrate the burning of wax.
The dry clay mold is placed upside down on the stove, and under the burning and licking of the fire, the wax inside the clay mold gradually softens, melts into wax juice, and drips out of the clay mold continuously.
When the dripping is complete, the clay mold used to cast the cannon is completed.
After the cannon blacksmith demonstrated the second step of making the clay mold, he led several apprentices to the nearby iron melting furnace.
The runner of the iron melting furnace is one out of six, which can divert six strands of iron or copper at the same time.
The ground around the furnace was also hardened and paved with thick concrete, but below the six outlets of the converse channel there were six cylindrical pits just enough to place mud molds.
In addition to coal, there was also a lot of earth around the furnace, and the apprentices picked up shovels and began to fill the cylindrical pit.
A layer of soil is laid at the bottom of the pit, and then the clay mold is placed into a cylindrical deep pit, and the clay mold is filled with earth around it.
The cylindrical pit is cast according to the siege cannon of more than 1,000 catties, in order to adjust the height so that the iron juice just flows into the mud mold, there is more soil on the pad, Zhu Shun waited for a long time.
During this time, the gunsmith commanded several apprentices to start burning the fire and smelting the iron, and when the clay mold was filled, the iron was almost smelted.
The iron juice slowly flows down the runner into the mud mold, and after the casting is completed, it is kept warm for one to two days before being dug out of the cylindrical deep pit.
Zhu Shun didn't have time to wait here for a day or two, so he walked to a furnace not far away, where the clay mold was kept warm for one or two days, just in time to be dug out of the cylindrical deep pit.
Beginning to excavate the clay mold, Zhao Doumi watched an apprentice start to manipulate the gear drive shaft system, and couldn't help but sigh: "Teacher, this time reflects the great advantages of the industrial revolution." ”
"It's just a few dozen catties of tiger squat cannons, three or four apprentices can pull up the clay mold, if this is replaced by a five-hundred-pound or even a thousand-pound Hongyi cannon, ten people can't pull it."
"Our cannon casting workshop only needs a skilled worker who is proficient in steam manipulation, and he can easily pull up thousands of catties of Hongyi cannons, saving a lot of manpower."
Zhu Shun was very indifferent to the scene in front of him, and smiled at his disciple Wen Yan: "When the steel mill is established, it will be called a spectacular, and it will not be too late to sigh at that time." ”
Zhao Doumi, who specializes in the art industry and is proficient in firearms manufacturing, can't think of what a spectacular scene an industrialized steelmaking plant is if he wants to break his head.
Next to the molten iron furnace in the cannon foundry.
An apprentice first dug out a clay mold and smashed the outer layer with a hammer, revealing the black cannon body.
Several thick iron chains were dragged over and wrapped around the cannon body, and the ear used to adjust the angle of the red-coat cannon just blocked the iron chain to prevent the chain from slipping out.
The other end of the thick iron chain hung from an anchor-style iron hook, and as the apprentice maneuvered, the geared shaft system began to move, slowly pulling up the Hongyi cannon weighing a thousand catties.
At the moment before the gear drive shaft system was started, Zhao Doumi pulled Zhu Shun away from here: "Master, although industrial machinery is easy to use, it is also very dangerous. ”
"In the past few years, six skilled workers have been disabled in the cannon casting workshop alone, and one skilled worker has been killed by iron chains, so it's better for the teacher to stay away."
