Ding Sifu got along with Gong in the shop happily and worked very hard. The person has grown fat and tall again, and he wears very decent clothes, all of which are the clothes made for him by Gong.

Aya'er is also very considerate of this little junior brother, and when she comes to visit her mother, she often buys him some delicious food.

Ding Sifu often sighed that he could be so happy. He misses Ding Pandi who has no news even more, I don't know how she is now, whether she is still alive.

The only thing that makes people uncomfortable is that occasionally the Wang family will have some trouble in the future. She asked Ding Sifu for money, but Ding Sifu still gave her fifty wen a month. She saw that her son was dressed decently, and there was a little candy in the house, and she didn't believe that he only took such a small amount of money.

Ding Sifu told her, "The clothes were made for me by my master, and the snacks and sweets were bought for me by my sister yesterday."

Wang wrapped up the food and took it home, and asked him to hint to the master that life at home was not good, and it was a pity that these fabrics were made for children, so it was better to give them to adults, and it was also a piece of filial piety for him.

Ding Sifu shook his head unwillingly, and was plucked by Wang's ears.

Wang was cheeky to complain to Gong again.

Gong said with a cold face, "That's the leftover ruler from the sale, and I can't sell it, so I put it together and made a few clothes for Sifu."

After saying that, he didn't pay attention to her anymore.

After Wang left, Ding Sifu went to apologize to Gong again, and his face was flushed with shame.

Gong smiled, "I know you're a good boy."

At the beginning of April, the new courtyard of the Ding family, that is, the east courtyard, was completely built. Ding Zhuang invited eight more carpenters to make furniture in the east courtyard, and when the furniture was finished and the yard was dried, he could move in.

For the furniture in the lilac boudoir, Ding Zhuang not only bought a few pieces of high-quality beech wood, but also asked the carpenter to carve flowers and birds.

Ding Shan also rented a shop in the county seat and named it Ding's Cloth Village. rented a shop with decoration and then added goods, and spent more than 220 taels of silver, and Ding Zhao borrowed 150 taels from them.

Ding Qin took his daughter-in-law Zhao and son Ding Daniu to live in the shop, and Ding Daniu also went to school in a private school in the county seat.

Ding Shan spent half of his time going out to buy goods, and half of his time living in the countryside, looking at the fields and houses in the countryside with Xie. Now that the family has money, the fields are rented to tenant farmers for planting, and a mother-in-law has been bought to do housework.

Ding Zhen was completely relaxed, in addition to learning to read and write with Lilac, she was doing needlework.

Xia Er's family also put Ding Shan's grocery store in the town down, and Xia Dahe went to guard the shop during the day.

At Lilac's suggestion, Ding Zhao bought a mule.

The mule is beautiful and as majestic as a horse. The mule is used as the family's chariot, and the old cattle are rented to tenant farmers or villagers in turn.

Ding Zhuang made several honey incense pendants for his family, and Ding Zhao, Zhang's, and Ding Lichun's brothers handed them over to Ding Zhao for safekeeping, and they would be worn later. His and Ding Lilai's were kept by him, and he gave the small gourd of Lilac to Lilac.

The small gourd is only the size of a clove thumb, dark red and shiny, with curved golden lines, exuding a silky sweet fragrance, and is worn on a red silk thread.

Lilacs love it.

I really want to wear it.

Ding Zhuang smiled, "Coincidentally, a piece of fragrant wood, the texture is gold thread in this place, and black thread in other places. Ye knows that you are precocious, and this thing will be kept by yourself. You can't wear it now, and don't let anyone see it. When you grow up, your father says when you can wear it, you can wear it again."

The cloves were taken back and hidden.

One day at the end of April, Ding Zhao brought back good news that the Li Foundry could no longer operate.

"If nothing happens, I can buy it in two days. After buying it, I bought five acres of land next to it to build an iron shop, and Ding's iron shop moved there."

The girl is right, the two places are next to each other, the iron billet is cast on the other side, and the iron is struck here, which is convenient.

Lilac said, "Five acres are small, buy ten acres."

Five acres is only enough to build an iron shop, and there will be an office area and a rest area for employees when there are more people in the future.

Ding Zhao definitely listened to his daughter, and agreed happily.

On the third day, Ding Zhao bought the Li foundry and spent three hundred and twenty taels of silver. Although the place is relatively large, it is outside the town, and the land is cheap.

Ding Zhao again

Bought ten acres of wasteland next to it.

Ding Zhuang and Ding Zhao don't know how to cast, but as long as it is related to iron, they like it, and they are happier to buy a foundry than to open a Jiulu Weaving and Embroidery Pavilion at home.

Casting and striking iron are both related to iron, and they discussed for a long time and came up with the name "Ding's Iron Workshop".

Lilac disagreed, feeling that using a surname limited development.

The name Lilac has long been thought of, and it is called "Baoqing Iron Manufacturing Company", referred to as "Baotie".

When the steel is smelted, it will be called "Baoqing Iron and Steel Manufacturing Company", referred to as "Baosteel".

Only Lilac understands the meaning of these two words. The construction of the largest steel factory in the Dali Dynasty is her lifelong goal.

There are two institutions under Baoqing Iron Manufacturing Company. Of course, it cannot be called a workshop or a branch factory, but a foundry workshop and a forging workshop.

As soon as she said her name, not to mention that Ding Zhuang and Ding Zhao liked it, Ding Liren and Ding Lilai also liked it.

I think the name is high-end and atmospheric.

Ding Xiang also instructed Ding Zhao's father, "We must keep the casting craftsmen with good skills, and increase the monthly money to their satisfaction."

In the previous life, Lilac knew that the ratio of molten iron to rare earth was three percent, but the rare earths used in molten iron in the previous life were refined. This proportion of unrefined rare earths depends on the craftsmen to grasp the degree through trial and error.

In addition, Lilac also knows a means to improve the quality of ductile iron, which is to use the low-temperature graphitization annealing process, put the cast iron parts into the furnace, heat the temperature to about 700 degrees, and then turn off the fire and slowly cool it to about 500 degrees, and then pull it out to the air to cool to room temperature.

Cast iron treated in this way is able to produce a ferrite matrix and a more round spherical graphite, similar to steel, which improves the strength and toughness of the iron, and the casting is less prone to brittle cracking.

When the cast iron is heated to a dark brown surface, the temperature reaches about 500 degrees. When the surface color of the iron casting is cherry red, the temperature reaches about 700 degrees. The higher the heating temperature, the brighter the iron surface.

In the past, there were infrared thermometers and other temperature measuring instruments, but in this era, there are none, and these have to rely on the visual inspection and experience of craftsmen......

A good craftsman is especially important.

The next morning, Ding Zhuang and Ding Zhao took Lilac to the "Baoqing Iron Works Manufacturing Company" in a mule cart.

"Baotie" is two miles away from the town, not far from the Black Dragon River. If it takes half an hour to walk from Beiquan Village, it will take more than two quarters of an hour to take a mule cart.

This is a rough country road, and it will save time if it is easy to walk.

The old foundry covers an area of more than 20 acres, plus the 10 acres bought later, adding up to more than 30 acres, and Lilac feels that it is still small.

Jiulu Weaving and Embroidery Pavilion is just a side dish, and "Baosteel" is the support for the future of the Ding family, and even has a far-reaching impact on the Dali Dynasty.

Lilac looked at the broken field that stood in a wasteland, and offered to buy another twenty acres of land.
