148 Iron and steelmaking

When Quan Zhenhai and the others heard this, they finally couldn't help but complain and said, I know that everyone has ideas in this regard, but now let's listen to Brother Hua, and leave time for everyone to discuss it later, okay?

The crowd was a little quieter.

"Well, please listen to me continue to explain, this complete set of equipment also includes hot metal ladle, silo, and has its own power packing conveyor belt, pulverized coal combustion, blower equipment, of course, slag discharge, tapping, transportation rail car, mold pouring and other tooling process equipment.

However, I am more worried about the refractory materials in the small blast furnace. For now, we have the materials in the furnace that Anna gave us, and the quality is very good and there are spare, and I climbed into it when I visited the cave.

However, I am more concerned about what happens when the spare materials are used up? We have to make our own refractories before these spare materials are depleted, and everyone, we're under a lot of pressure!

Fortunately, the current temperature conditions of the furnace are excellent, and the reserve of refractory materials should be able to continue to operate for several years, but everyone must understand that such consumables must be able to produce by themselves, even if the quality is a little worse and the consumption is a little larger. ”

"Sure enough, it's still the life of the refractory material, so I'm worried about this......

"I also have to say that if the quality of our own refractories is not up to the level of the old world, it may affect the quality of our iron smelting."

Before Holley finished speaking, some people in the venue couldn't help but make a comment, so Holley quickly raised his voice and explained to everyone:

"Regarding this question, I would like to ask Xiao Cao, what is the quality of the clay kaolin needed to make refractories in this archipelago, and how much is there? Can it be used as a refractory material? ”

Hua Li turned back to Cao Limei and asked.

"Clay kaolin is there, but it's very small, and the grade is very low, and we have to go out...... Oh, by the way, Brother Hou, you are engaged in building materials, refractory materials you should be good at, I don't know if ordinary clay can replace clay kaolin, because there are a lot of ordinary clay in this archipelago. ”

Cao Limei's eyes searched in the venue, and finally looked at Hou Xianglin and asked.

"Yes, but the life of high temperature resistance must be compromised......"

Before Hou Xianglin finished speaking, Cao Limei suddenly patted her head and said:

"Oops, how did I forget! In fact, clay mixed with low-grade bauxite can also be made into refractory materials, but the temperature resistance and service life are slightly shorter, and there is low-grade bauxite in the east of this island! ”

"Yes, Xiaocao, I heard you say, there is some bauxite or something."

"It's laterite-type bauxite, and there is a little bit near the coastline in the eastern part of the island, but it doesn't seem to have much mining value because there are too many impurities. For the more pure, you should go to Weipa on the other side of the sea, where the world-famous bauxite is located. ”

Cao Limei replied.

"The problem is that we can't get out of this island at all."

"In the early stage, there is no need for this iron-smelting furnace, and people are talking about the future development plan of the metallurgical industry."

"Okay, I'm sleepy again......"

Someone muttered something in a low voice, causing a snicker from the people around him.

At this time, everyone heard Cao Limei say loudly:

"Hey! There is a way, there is a way! Don't worry, let's not crook the building now, hurry up and listen to Holley's introduction! ”

Hua Li paused, and saw that everyone did not continue to crook the building, so he continued:

"The following content is still told by Brother Quan, everyone, Quan Zhenhai once worked as a technician in the foundry workshop for a year, and he is more familiar with the following equipment than me."

Quan Zhenhai nodded, took a few pieces of paper handed over by Holley and continued to introduce:

"Well, now it's time to talk about sand casting equipment, the list of assistance includes a full set of pouring tooling such as sand mixing molding core, shot blasting, etc., in addition, it is also equipped with a spare three-meter water-cooled cupola. I heard from Xiao Cao that the quality of the casting sand on our island is good, so the basic conditions for the production of our industrial castings are still available.

Finally, I would like to explain that in the future, the location of our steel plant should also be selected with dim sum, which should not only take into account the transportation of iron ore, but also be close to coal mines, preferably from sea sand production areas. ”

"Well, in fact, you don't need sea sand yet, this island has a large amount of Quaternary river and lake sedimentary silica sand, just upstream of the pyrite river."

Cao Limei lowered her head and flipped through the information in her hand, and raised her head to respond to Quan Zhenhaidao.

"In my opinion, it's better to build your iron-making blast furnace near the pyrite vein."

"It should also be the site of Mr. Zhao's sulfuric acid boiling furnace, right?"

"Although the silica content of river sand is not as high as that of the seaside, it should not be a problem to engage in casting and the like."

"Yes, we can reduce as much as we can reduce such things as raw material transportation, our means of transportation are insufficient, unless the production is large-scale in the future, then we can build a railway to solve the problem of raw material transportation, there is no such condition in front of us."

Seeing a group of science and engineering men start to discuss problems on their own again, the onlookers who eat melons suddenly yawned.

At this time, Mr. Sun hurriedly said to the men of science and technology, you should continue to introduce you to the list of metallurgical assistance, and you will discuss the specific technical problems later, okay?

A group of science and engineering men immediately said Oh, I'm sorry and forgot, we won't be like this in the future, what, Brother Zhenhai, it's time for you to continue.

"Okay, first of all, let me explain that the cupola furnace in the casting equipment is used for iron, and of course it can also make iron, but because the structure is slightly different, the furnace temperature retention ability is not as good as the iron-smelting furnace that Holley just said, so the quality of the smelted iron is not as good as the former."

"Hey! I can't see the stove right now! ”

"Metallurgy, I don't think we should do it at the beginning, it's too tiring!"

"Look at us, Ang? Do you look like a steelworker? ”

"Yes, a group of otaku, after crossing over, they actually ran to carry ore to make iron? It's unimaginable! ”

Sure enough, many people did not pay attention to the site selection and transportation issues discussed later, but were uneasy about the new furnaces in the aid project, because one more furnace would greatly increase the labor intensity, which is what everyone really cared about.

"Well, everyone, the furnace here is mainly used for iron, of course, it can also smelt iron ore, as far as I know, in the Song Dynasty, the cupola furnace was directly smelted iron and then directly cast."

Holley hurriedly explained on the side, but he obviously didn't get to the point.

"Brother Hua! We're not talking about the same thing! ”

"What's that?"

"Forget it...... Just when we didn't say it! ”

"Then please continue to introduce the whole brother......"

Holley immediately got off the donkey.

"Well, now let's talk about the complete set of miniature top blowing converter steelmaking equipment, which is our highlight in the future!"

Quan Zhenhai looked at the information in his hand again, and raised his eyes to look at everyone:

"These include an electric rail cable car, a ladle type iron mixing furnace, a three-meter electric micro converter, a high-pressure water-cooled top blowing system, a packing bucket and a 1.5-ton crane.

The ladle is very small, and there are only about 200 steel tapping at a time...... Less than three hundred kilograms. According to a conservative estimate, if continuous production, the molten steel will be produced every hour."

"Hey! We're going to be exhausted! ”

"yes, do we need to make steel every day?"

"You can take shifts......"

"Hmph, you try it in consecutive shifts! Three shifts is really terrible! ”

"It's less than 300 kilograms at a time, it doesn't seem to be tired, right?"

"Once the furnace is opened, it can't be stopped, unless it waits for an overhaul to stop!"

"Why?"

"Because it's not economical!"

"We don't have to worry about the economy or not in the early days, right?"

"That's ...... too"

"Well, really, we will all be all-rounders in the future, we will be able to make steel, iron, cement burning, and ......"

"You also need to be able to dig coal, move bricks, drive boats, and shoot cannons!"

"Nima, who said that the puppets are little white puppets, who is in a hurry!"

"It's a real test of life for us......"

"Why do I feel so happy and fulfilled in this life?"

"That's because you're pretending to be a force right now!"

"Uh-huh, it's a good pair to be very stupid and naΓ―ve, and it's a horizontal batch: through the invincible ......"
