Lilac's reason is, "If you want to do it, you have to do the best, look at the Jiulu Weaving and Embroidery Pavilion, you have invested a lot in the early stage, and you have earned a lot later, and even people in the capital and Jiangnan have come to buy goods." After Baotie is done well, the iron tools produced will be sold all over the country, and more people will be recruited to expand the scale......"

Ding Xiang looked forward to the future, and Ding Zhuang and Ding Zhao were enthusiastic when they heard it. They didn't dare to think of that kind of good thing, but they were happy in their hearts, and twenty acres of wasteland were only fifty taels of silver, so they happily agreed.

Covering an area of more than 50 acres, it can be regarded as a medium-sized enterprise.

Lilac is satisfied.

The foundry is extremely dirty and messy. Casting is dirty work, but it's still uncomfortable to be so dirty.

Lilac wrinkled her nose and said, "Look at this place, his family will not collapse, who will collapse." It's like the eldest grandfather's house, dirty, messy and untidy, so life is not as good as our family and the third grandfather's family. ”

The simplest language contains profound philosophical ideas.

Ding Zhuang and Ding Zhao thought so.

Several people stopped and went, planning how to renovate and expand the "Bao Tie".

Lilac worked in a steel company in her previous life, occasionally going to the workshop to run errands, and she recalls the scene at that time and gives advice.

I came to a large room, and there were many large barrels in it, and there was a mouth on the edge of the barrel.

Lilac knew that these bucket-like containers were called molten iron ladles in the previous life, and they were specially used to hold the burned molten iron. It is made of refractory bricks and pasted with a layer of refractory mud on the outside.

Ding Zhao said that these were ladles of molten iron, which were used to cast iron.

This life is also called molten iron ladle.

Lilac's expression was exaggerated, her eyes were wide, her mouth was half open, and she looked incredible.

Ding Zhuang was surprised, "What's wrong with Xiangxiang, what's the matter?" ”

Lilac glanced at the craftsman next to her, shook her head and said, "It's nothing." ”

Ding Zhuang and Ding Zhao could see how insincere what Ding Xiang said, and they thought about something to say when they went home.

Unconsciously, at noon, Shi and Liangzi went to the town to buy some wine and food and came back, and several people continued to discuss after eating.

Ding Xiang proposed, "Jiulu Weaving and Embroidery Pavilion has a lot of investment and earns a lot. Bao Tie is done, and it is more profitable than the Weaving and Embroidery Pavilion. Don't feel sorry for the silver, the flower must be spent. ”

In two months, the weaving and embroidery pavilion made a net profit of more than 3,000 taels of silver, which can be regarded as a daily income. can earn so much, mainly thanks to the accumulation in the early stage and the novelty of the buckle.

As other families make buckles, the income of the Weaving and Embroidery Pavilion will definitely be greatly reduced. But the reputation has been beaten, and the business is still better than other embroidery workshops.

Ding Zhuang's father and son like iron bumps and are willing to throw money into it.

Before the end of the day, Ding Zhuang took the sleeping Lilac on the mule cart and went home.

After dinner, Ding Xiang had a secret conversation with Ding Zhuang and Ding Zhao.

She took out the piece of Rare Crystal Earth and said, "Grandpa, Daddy, I always feel that Feifei took me to the Rare Crystal Earth, which has a deep meaning. It's like it brought our red apple and attracted me to Jitou Peak, where I found Ganoderma lucidum and honey butter, which saved my grandfather's life and made our family rich. ”

Ding Zhuang and Ding Zhao nodded. It was indeed Feifei who brought the red apple from home and attracted the fragrance to it.

Ding Zhao asked, "What do you mean by a girl?" ”

Lilac said, "I wonder every day what is good about this piece of soil and why Feifei is taking me there." I thought about it day and dreamed about it at night, and one day I really dreamed of dilute crystalline earth. ”

Ding Zhuang was very surprised, "What did Xiangxiang dream of?" ”

Lilac said, "I dreamed of a big bucket with a mouth smeared with mud inside, somewhat like the ladle I saw in the foundry today. At the bottom of the vat was a small pit surrounded by mud, in which the thin crystalline earth was placed, and a thin sheet of iron was covered with it.

"When the red molten iron is poured in, the molten iron inside immediately explodes, and it looks as beautiful as fireworks set off during the Chinese New Year. After calming down, it is poured into the mold and it becomes a different shape...... Later, they were put in the kiln, heated until they were cherry red, then turned off the heat until they were dark brown before pulling them out. ”

She couldn't say that the molten iron had a spheroidization reaction with rare earths, and the cooled iron structure turned into ductile iron, and then annealed heat treatment to further optimize the matrix structure of ductile iron.

Lilac's eyes were full of confusion, "I've dreamed twice, and the scene is exactly the same on both occasions. It's weird. ”

Ding Zhuang and Ding Zhao glanced at each other. They all remembered that when Xiangxiang was more than a year old, they dreamed that Hao pricked her with a needle, and later Hao really put a needle on her.

Ding Zhuang felt that this dream must have been entrusted to Xiangxiang by An An, and it must be accurate.

Ding Zhao felt that this dream must have been entrusted to Xiangxiang by his mother and second aunt, and it must be accurate.

Both of them looked solemn.

Lilac said, "I just thought about it, I thought that my grandfather said that the purpose of adding dilute crystalline clay to the kiln is to increase the hardness, so will adding dilute crystalline clay to the molten iron also increase the hardness?" I can't figure out why the color of molten iron has changed...... I had a headache when I thought about it, and I didn't dare to think about it anymore. ”

Speaking of the back, the mouth is pouting.

Ding Zhuang and Ding Zhao's eyes lit up.

Yes, ceramics and dilute clay can increase hardness, and molten iron and dilute clay may also increase hardness. As for why iron objects change color, there is always a reason.

Ding Zhuang said again, "Xiangxiang again." ”

Lilac thought about it and said it again.

Ding Zhao was afraid that he would forget, so he took out a piece of paper and wrote it down.

Ding Zhuang picked up Lilac and said, "Good granddaughter, don't think about it again if your head hurts, leave this matter to grandpa and daddy." He also said to Ding Zhao, "You can do the expansion of the workshop and the relocation of the iron shop, and I will take someone to cast iron tools with dilute crystalline clay." Don't be afraid to spend more money, if this thing happens, our ironware will definitely be able to sell well. ”

Ding Zhao said with a smile, "Not only can iron be sold, but it may also be able to work for a long time." ”

His face was flushed with excitement, and even his nose was a little red. Iron tools are good, not to mention civilian farm tools and knives, there are simply too many uses.

Lilac happily held Ding Zhuang's big black face and took a sip. Grandpa is a top craftsman, although he is not a casting craftsman, but he has been dealing with iron all his life, and he has the spirit of study, and he will definitely be able to succeed in trial production.

Daddy is right, it is a good job to make good iron tools.

When ductile iron was produced and the quality of civilian knives and agricultural tools made by "Baotie" was greatly improved, it was proposed to improve firearms and cold weapons, and then find a way to make steel.

The next day, Ding Zhuang took Li Maigao and the old scalper into the mountain, stayed at Grandpa Zhang's house for a night, and came back the next day. He and Li Maigao each carried a basket of dilute crystalline soil, and the old ox camelped four baskets.

also told Grandpa Zhang that he would spend money to find someone to carry five baskets of dilute crystal soil out every ten days.

After that, Ding Zhuang often went to chat with craftsmen who knew how to cast, and also went to the Wanshi Foundry Factory, which was hundreds of miles away, to recruit a craftsman with a high salary.

The high-end iron research team was formally established.
