Bright Sword: Starting from the Improved Grenade

When talking about steelmaking, the first thing that comes to mind is definitely converter steelmaking.

But with Zhao Tianyang's current conditions, he couldn't use a converter to make steel, so he chose the simplest and lowest-cost traditional steelmaking method.

Zhao Tianyang first found Chang San and Li Tie and asked them to bring some people to dig some clay back.

Then he ran up the mountain and found Chiyu Village, which came to help them build the factory. The village chief asked him to help buy some refractory bricks and hire a few bricklayers.

"No problem. Director Zhao, I'll tell you the truth. My nephew has opened a brick and tile factory in the nearby Qinglian Village. Just tell me how many refractory bricks you want and we'll deliver them to you tomorrow. As for the bricklayers, let alone the price."

The village chief pointed to a few men carrying cement nearby and said, "They are the best bricklayers within a ten-mile radius. Whenever you need their help, just let them know."

"Okay, let's get a thousand firebricks first!"

Zhao Tianyang thought for a moment and said.

"no problem."

The village chief agreed generously, then hesitated and asked, "Director Zhao wants refractory bricks, and the masons want to build a coke oven?"

"how do you know?"

Zhao Tianyang asked in surprise.

"Hey, what's there to not know? Shanxi is a major coal-producing province, and we know coking very well."

The village chief was inexplicably enthusiastic: "If Director Zhao trusts me, just teach me this job. My nephew will be able to build a coke oven, and I guarantee it will be built well for you!"

"also."

Zhao Tianyang thought about it. He knew something about coking ovens, but not very well. Since the village chief said so, he agreed.

"Great."

The village chief was delighted, put down his hoe and asked, "I wonder how big a furnace Director Zhao wants to build?"

"Of course the bigger the better!"

Zhao Tianyang makes coke for steelmaking. What will happen if there is less coke?

Hearing this, the village chief was even happier: "How about a furnace with 36 holes and an area of ​​35.4 m3? It only requires more than tons of refractory materials."

"Okay, how much does it cost in total?"

Zhao Tianyang nodded and agreed.

"Well... well... how about two hundred dollars?"

As if afraid that Zhao Tianyang would not agree, the village chief quickly explained: "It's mainly because a lot of refractory bricks are needed, and it takes a lot of manpower to build a large coke oven, so it costs a lot of money."

"I'll give you two hundred dollars. Can you finish it within a week?"

Zhao Tianyang waved his hand and said that money was not a big deal, what was important was time.

"No problem. I'll go down the mountain right away and arrange this for Director Zhao."

After saying that, the village chief went to the side and found Li Yuncai, who was busy digging stones. He said, "Deputy Director Li, I want to ask for leave. Your director wants me to help him repair a coking oven."

Hearing this, Li Yun glanced at Zhao Tianyang who was not far away and saw him nod. Then he wiped the sweat from his head and said, "No problem, but if you don't go to work, you will lose the wages!"

"No, no, I don't want it today either."

That’s right, these villagers are not here to help for free, they have to be paid.

However, the money was given by the boss and Zhao Tianyang didn't have to worry about it. Li Yuncai was only responsible for recording the time and number of people working.

Soon the village chief went down the mountain and came to the next village (Qinglian Village), where he found his nephew who was making bricks at the brickyard at the east end of the village.

"Uncle, why are you here?"

Yang Ming wiped the sweat off his face with a towel and asked.

"Busy now!"

The village chief walked over and said, "I got you a big order today. How are you going to thank me?"

"A big order? How big?"

Yang Ming asked doubtfully.

"not much."

The village chief stretched out his hand and gestured: "Only two hundred dollars."

“Two hundred dollars!!”

Yang Ming, who was squatting, suddenly jumped up: "How much? Two hundred? What kind of work pays so much?"

"Build a large coke oven."

The village chief said proudly.

"It's easy. I have plenty of firebricks here. I'll go to the village to call for help. Let's go now!"

After saying that, he called a servant to watch over the kiln, and then followed the village chief back to the village to call people.

Soon, Yang Ming led a team of more than one hundred people of different ages, with the youngest being fourteen years old and the oldest being over forty years old, pushing carts pulling refractory bricks, and rushed to Huangya Cave.

In the small basin of Huangya Cave, Zhao Tianyang and Yang Ming discussed the details of building a coking oven. It was not until then that Zhao Tianyang realized that there were so many things to know about building a small coking oven.

A small coking oven consists of six parts: carbonization chamber, combustion chamber, heat storage chamber, inclined area, furnace top and flue.

In addition, in order to ensure the sealing of the coke oven, a large number of special-shaped bricks are used. Usually, a large coke oven will use more than 400 types of bricks.

After understanding the complexity of the coking oven, Zhao Tianyang gave up the idea of ​​giving some advice. Since others were professionals, he would not make things worse.

After giving Yang Ming a few instructions, he ran to Chang San and Li Tie and started building an earthen blast furnace with them.

In the past, because the requirements for earthen blast furnaces were not high, he used clay and red bricks to build them. Now that he wanted to make steel, he chose to use clay and refractory bricks, so that he could squeeze out the ultimate performance of the earthen blast furnace.

After a busy week, two earthen blast furnaces and a coking oven stood in the small basin. Seeing Yang Ming, who was depressed due to working overtime every day, Zhao Tianyang hurriedly took out two hundred yuan and gave it to him.

"Thank you, Director Zhao."

Yang Ming became more energetic after receiving the big money. Although the two hundred dollars still need to be deducted for labor and material costs, he can still earn forty dollars conservatively.

Thinking of this, he decided to buy two chickens when he got back and give ten dollars to his uncle, so that he would know that such a good job would be introduced to him in the future.

"Let's go, everything is packed up, let's leave!"

Yang Ming shouted loudly to his helpers.

Seeing this, these people knew that their wages should be paid, so they picked up their tools and followed.

"Okay, it's our turn."

Zhao Tianyang rolled up his sleeves and got to work.

"Wait a minute, Director. This furnace has just been built. It needs to be aired for a few days."

At this time Li Tie pulled him and reminded him.

"Look at me, I'm so busy."

There was no other way, Zhao Tianyang could only wait for a few more days.

However, he has not been idle these days. He has started to work on another thing that the radio needs, the light emitting diode.

As the only luminous device in the radio station, it is relatively easy to make. You just need to use diamond abrasive and wire.
