Introduction to the process and equipment of iron and steel plant

Iron and steel industry is one of the important basic industries of the country, involving all aspects of the country's economic construction. The following is an introduction to the process flow and equipment of iron and steel plants.

I. Process Flow

The process flow of iron and steel plant mainly includes three main links: iron making, steel making and steel rolling.

1. Ironmaking: Iron ore, coke, limestone and other raw materials are smelted through the blast furnace to obtain liquid pig iron. 2.

2. steelmaking: smelt pig iron, scrap steel and other raw materials in the converter, electric furnace, remove impurities, adjust the composition, and get the molten steel.

3. Rolling steel: steel is cast into billet through continuous casting machine, and then made into various specifications of steel through heating, rolling and other processes.

Second, the main equipment

1. Blast Furnace: Blast furnace is the main equipment for ironmaking, mainly composed of furnace shell, furnace lining, furnace bottom and so on. Blast furnace through the hot blast furnace to provide hot air, so that the raw materials at high temperatures in the reduction reaction, to get pig iron.

2. Converter and electric furnace: Converter and electric furnace are the main equipments for steel making. Converter through the oxygen top blowing method or bottom blowing method, etc., the pig iron in the impurity oxidation removal; electric furnace through the electrode produces electric arc heat, melting scrap and other raw materials, remove impurities, get steel.

3. Continuous casting machine: Continuous casting machine is the equipment to cast steel into billet. It is through the crystallizer will be continuous casting of steel into a certain shape of the billet. 4.

4. rolling mill: rolling mill is the main equipment for rolling steel. It is through the billet after heating, through a number of rolls of grinding, made of various specifications of steel. Modern rolling mill with high precision, high efficiency, can realize automatic production. 5.

5. Auxiliary equipment: In addition to the main equipment mentioned above, steel mills also need a variety of auxiliary equipment, such as cranes, conveying equipment, dust removal equipment, etc., to ensure the smooth progress of production.

Third, environmental protection measures

Modern iron and steel plants in the production process, attaches great importance to environmental issues. Various measures, such as the construction of dust removal devices, the use of environmentally friendly materials, optimize the process, etc., to reduce emissions of waste gas, waste water, noise and other pollutants to achieve green production.

In conclusion, the process and equipment of the steel plant is a complex system. Professional technicians are needed to operate and manage them. With the progress of science and technology, the production efficiency of iron and steel plants is improving, and the environmental protection measures are becoming more and more perfect, making an important contribution to the economic construction of the country.
