"This is our company's ore stockpile, and the current ore has domestic mines, and there are also many foreign mines. At present, the proportion of foreign mineral imports is increasing, and the growth rate is very fast. ”

"Companies like ours can be regarded as large-scale enterprises in Tangshan, and basically we can't find too many companies bigger than us, of course, we don't compare with him with Tangsteel's goods, people can drown us if they pee, and just get some ore is enough for us to produce for a month." Li Feng said, telling Chen Shu the names of these devices as he walked.

"How much iron ore does our side consume in a day, and how many billets do we produce?" Chen Shu paid attention to these things as he walked.

"More than 7,000 tons of iron ore are consumed a day, and about 3,900 tons of billets are produced. Needless to say, increasing production capacity and reducing consumption includes two aspects, one is to increase the rate of molten iron during ironmaking, and the other is to reduce the consumption of coke, gas and electricity. Li Feng continued to explain.

"Our molten iron is never sold, it is made and cast into billets by ourselves, just now we are looking at the material yard, along the transmission belt, here is the sintering workshop. It is to burn the iron ore powder into a block, and then crush it into a block that is most suitable for iron smelting, and the size is generally not less than 5mm. Li Feng said.

"The iron ore that comes in will be added with a lot of auxiliary materials, adjust the composition of the ore, and then go through the sintering workshop, there will be gas jet heating on it, so that the iron ore will condense into lumps, and the flame temperature will be more than 1,000 degrees. The trolley that walks forward with the iron ore is called, and this thing is especially easy to break at high temperatures. Li Feng explained while taking Chen Shu into the sintering workshop.

The employees in charge of this section wear overalls and constantly move between the conveyor belts and the motors to prevent unplanned downtimes. As soon as I entered, I was sweated by the high temperature inside, no wonder no one wanted to bring myself to the workshop to visit and study.

"Our factory has a coke oven, which is to burn coal into coke, and the gas produced is used for sintering, and blast furnace ironmaking will also be used, which is called coking gas. Some factories have already started to purchase lump ore or sintering balls, eliminating the need for sintering. "The two walked through the sintering workshop, and no one was willing to approach the heated high-temperature roast.

It had taken more than half an hour since he entered the ore yard and walked here, and Li Feng kept introducing Chen Shu to his dry mouth. It's a pity that Chen Shu didn't expect that the working environment of workers would be like this. After coming out of the sintering workshop, Chen Shu ran to the company's commissary, took four bottles of cold mineral water, and ran back.

The two of them each opened one bottle, and Chen Shu carried the remaining two bottles and continued to walk along the section. When I approached the blast furnace, I found that the surrounding temperature was not high, and at first I thought that the blast furnace must be too hot to get close.

"This is the blast furnace, there is a water cooling layer on the outside, and there is a water circulation to cool down all the time. We have blast furnace accessories and blast vents here, and I'll take you to the taphole, where the temperature is high. Saying that, Li Feng slowly bypassed the nearby equipment, and the workers on the platform occasionally looked at Chen Shu and Li Feng.

Obviously, many people here know Li Feng, which makes Chen Shu very surprised, how can these people know Li Feng? One is sales, the other is a first-line workshop, and the environment here is definitely not who wants to come, that is to say, Li Feng and these people are definitely not much, the probability of acquaintance should not be high, right?

Just after bypassing it, the terrifying high temperature hit my face, I just drank a few sips of cold water, and the sweat on my forehead was just clean, and it was pouring out quickly at this moment. I really don't know how to imagine what it is like for these workers to stand here every day in order to support their families.

Originally, I thought that it was hard enough for migrant workers to brave the scorching sun to work, but I didn't expect that the working environment of the workers in the industrial workshop was not much better. The difference is just that the wages of these workers are much higher than those of migrant workers, but there are also many risks, sometimes even life-threatening.

The reddish molten iron flows out of the outlet of the blast furnace and flows down the trench into the hot metal tanker. The workers' overalls here are much heavier than the overalls they wear, and although they can isolate some of the heat, they are still unbearable.

"Director Sun, are you staring at the shift today? This is Chen Shu from our new steel pipe factory, take him over to have a look. Li Feng shouted to a man wearing a red hard hat on the monitoring platform.

"Hello! I'm Sun Qiang, just call me Brother Sun!"

"Hello Director Sun, this is really hot enough, drink a bottle of water!" Chen Shu said hello and handed over the two bottles of water he was carrying.

Director Sun was not polite, stretched out his hand to take it, and then beckoned the workers below who were guarding the molten iron. "Lao Li, come over and give you a bottle of chilled mineral water, given by our new little brother!" After speaking, Director Sun smiled at Chen Shu, and Chen Shu also laughed.

If the leaders at the grassroots level were like this, I am afraid that there would be no factory that would not be able to do a good job. The workers who came over wiped their sweat with the towel around their necks, took the water from Sun Qiang's hand and said thank you, turned their heads and said thank you to Chen Shu and Li Feng, then unscrewed the lid and drank a few sips, and returned to their posts.

"Director Sun, how many degrees of molten iron is here?" asked Chen Shu.

"It's about 1500 degrees, and our blast furnace is not far from the steelmaking side, so there is no special treatment. Director Sun explained.

"How to cool down the furnace body? Is it circulating water to cool down?"

"It is closed circulating water, and the water is softened, which can prevent the formation of scale, which is not conducive to heat conduction, and can also corrode the piping system inside. The blast furnace is all about water circulation cooling, and I have never heard of any other way. Saying this, Director Sun also unscrewed the cap of the bottle and took a sip of water, and then greeted Chen Shu.

"Come up and have a look, I guess you won't be here many times. Chen Shu smiled and was not polite, and directly boarded the monitoring platform. There aren't many instruments here, probably not yet fully automated.

"The electronic display over there is the temperature of the cooling circulating water, the normal value is between 50-60 degrees, if it is too low, it may be that the temperature in the furnace is a problem, or it may be a problem with the circulating water system; if it is too high, the probability of problems with the furnace body is relatively large, and special attention is paid to each overhaul. The probability of a problem with the meter is very small, and when it is found that it exceeds the normal value, the first thing is to check whether the meter is broken, and this is also the best to check. Sun Qiang explained very clearly, without the slightest impatience.

Chen Shu looked at it for a while, stabilized some questions about molten iron, and then said thank you before getting off the platform. Li Feng below was already sweating profusely, so it was better to escape from this place as soon as possible.
