China is a vast country with many amazing scales. Among them, the iron and steel industry is in a leading position in the world, and the amount of iron ore in the mainland has reached 16.246 billion tons.
This astonishing figure makes many people feel that it is particularly strong and excellent, and can fully meet the needs of the market.
But what is puzzling is that China's annual demand for imported iron ore is particularly strong, and will also use heavy money to buy, the annual volume will be about 80%, from this figure, we can see that China is almost using imported iron ore.
What is the reason for this? After reading your sharing, the truth will be revealed.
1. The mysterious power of imported iron ore
Friends who don't know will think that iron ore is just an ordinary stone, and the composition in it is pure iron. In the eyes of many people, they don't think that its role is very powerful, then this idea is too simple.
Because the role of iron ore has an unshakable role on the mainland. These seemingly unremarkable iron ores not only contain iron, but also contain particularly precious metals, which can be refined through developed technology.
This process is particularly great and painstaking, and when the rare metals are successfully extracted, they can play a key role in the top fields.
Therefore, in order to better promote economic development and give full play to the power of environmental engineering, China resolutely chose to import iron ore. This will not only protect and store our existing ore resources in China, but also the iron content of imported iron ore will be of higher quality.
2. Why not use scrap iron recycling?
Although China has abundant ore resources, these iron ores also have disadvantages, that is, most of them are poor iron ore, which means that the iron content in them is relatively low. There is no way to make a greater contribution to our refined metals, and there is no guarantee of high quality.
And if you need to mine domestic iron ore, it will greatly increase the cost of mining. In this way, imported iron ore will be more attractive and the cost will be lower.
Then some people will also ask, why not use our scrap iron recycling? This question is not difficult to answer.
In addition to the output of scrap iron, and the need to calculate the results obtained after successful recycling, can it support the development of the mainland steel industry?
Obviously, this is more difficult, because the recycling of scrap iron is not concentrated, and the distribution of enterprises is relatively small.
It is understood that the mainland's demand for steel is 8.7 tons per year, while the recycling data of scrap iron is only about 200 million tons, and the gap between the two is too big.
We need to refine the rare metals in iron ore and use them in a larger market development space, and imported ore can ensure the quality of this metal composition.
However, there are many impurities in scrap iron, and the quality of the components in these scrap iron cannot be ensured, so it cannot be directly produced.
Not only does this process take a lot of time and effort, but it may also fail to produce high-quality steel with quality standards.
If we decide to make steel from recycled scrap iron, even if we use it all, we can't guess the economic loss.
In order for China to develop more comprehensively and steadily, and to make better changes to environmental pollution, China will decide to give up scrap iron recycling.
3. Find the whereabouts of scrap copper and rotten iron
Our China's scrap copper and rotten iron production also has good results, so how to deal with these scrap copper and rotten iron?
The mainland is a big industrial country, and the demand for steel is huge, and what we need is excellence. This scrap iron will not be wasted, and China is also working hard to use it, and the scrap iron produced every year will be put to good use for refurnace transformation.
They will cut the scrap of different sizes into small pieces, which will be smelted into primary steel.
Although the output of scrap iron is not small, only a small part can be smelted into high-quality steel. These scrap copper and rotten iron are recycled, which can also reduce environmental pollution.
Fourth, to build a green steel industry
The problem to be faced by the production of the iron and steel industry is the problem of environmental pollution, which is our primary task to solve, to minimize the degree of pollution and give everyone a greener environment.
Everyone's impression of steel emissions should still stay in the phenomenon that the emissions are very large, which will cause iron sparks.
For the reduction of exhaust pollution, we have made a lot of efforts and research on this issue, and in the case of perfect science and technology, we have also made great progress in China, and achieved one great achievement after another in the ultra-low emission of the steel industry.
The steel industry plays a pivotal role in the mainland and has made a lot of contributions to the development of the economic base. We continue to make progress to achieve green and low-carbon steel industry as the primary goal.
The country's emissions of sulfur dioxide, nitrogen oxides and dust per ton of steel have dropped by half, and have reached the international leading level.
In terms of environmental protection, the future steel industry will pay more attention to green and low-carbon development, and continue to develop new materials in line with the market. Through technological innovation, the industry will significantly reduce greenhouse gas emissions.
We can see a prosperous scene and more green industrial areas.
The steel industry is one of the industries with high energy consumption and carbon dioxide emissions, so energy conservation and emission reduction are important contents of environmental protection rectification.
It is necessary to intensify the reform of the energy supply side, improve the efficiency of energy utilization, promote the use of clean energy, and reduce energy consumption.
In addition, many equipment and technologies need to be continuously strengthened and updated to drive the development of more powerful new energy. In addition to technological innovation, the competition of steel enterprises in the future will also be reflected in the sustainable management of resources.
With the enhancement of global awareness of environmental protection, the recycling of resources and environmental protection in the production process will become the core role of enterprises to win the market.
5. The smelting process of steel
Steel needs to be smelted and requires a lot of scrap iron and iron ore, so the production process is very difficult.
Whether it is imported iron ore or scrap iron, we need to strictly follow each process, and the refining methods of different raw materials will be different. Strict staff are required to carefully control, which is an important step in the refining process.
Once the processing is complete, we need to transport it to the furnace for steelmaking operations, a step that quickly turns the raw material into molten steel, which can be processed for further processing.
This detail is also not to be missed, because through the electric furnace steelmaking, the impurities of the iron ore can be effectively removed, and the particularly pure molten steel can be harvested, ensuring that the quality of the steel is guaranteed.
After the above steps are over, we can start the molten steel refining, we can use the continuous caster, we can quickly complete the process of producing steel, and we can continuously burn the molten steel to get the solidified billet.
These billets can be machined to produce a wide variety of shapes.
Sixth, the work of the steel mill precautions
The people who work in the steel plant need to face the heavy task every day, and every detail must not be sloppy and must be cautious. Because the slightest mistake will cause safety hazards to yourself and everyone.
01Pay attention to fire and explosion prevention
Iron and steel plants need to pay attention to fire and explosion prevention accidents, always be vigilant, and prevent fire prevention awareness. The hazards of ignition can be correctly recognized.
During the production process, they also need to constantly monitor the condition of the equipment. Any detail issues that are found need to be maintained immediately. The surrounding environment is analysed and probed by instruments on a daily basis.
02Safe use of chemicals
The production and refining of steel is not a simple matter, and its process and process must be very meticulous and accurate, which is a problem that the staff needs to pay attention to in order to smelt better steel composition.
It is also essential for steel plants to use chemicals, and at the same time, it is also necessary to know more about the safety knowledge of use, so as to bring more safety guarantees to the staff and ensure the smooth progress of the work.
Strictly regulate the storage of all chemicals to be used, and each kind of supplies and materials need to be sealed tightly to avoid any unforeseen safety hazards. At work, you need to do a good job of safety protection and wear a mask.
03Safety of machinery and equipment
The production process of steel requires powerful technological equipment, so the equipment safety of each machine is a key concern.
Inspection and maintenance are carried out every day, and maintenance work is carried out from time to time to ensure that the machinery and equipment can operate normally every day. In the event of a failure, it can also be judged and tested in time to ensure the safety of the production process.
04 Safety of personnel at work
The behavioral safety of every employee should be paid attention to, know how to strengthen the sense of self-protection, and be familiar with all the rules of safety norms. You should not leave your job easily, and you should report to your boss for any personal reasons. It's a responsibility to yourself and your attitude to work.
When working, we must do a good job of protective measures, especially if you need to work at height, and you can't ignore the importance of protective measures.
Epilogue:
Through the above content sharing and discussion, I believe that friends have a full knowledge and understanding of iron ore. Iron ore plays an inseparable role in our China, and we need a huge amount of steel consumption.
Imported iron ore can provide advanced technological development for our steel industry and promote a greener and more friendly environment.
In the future, the steel industry will continue to innovate, and by recycling scrap steel and processing it, it can effectively reduce resource waste and environmental pollution. China will continue to advance the steel industry to find better solutions for economic and environmental balance.
