What is the use of charcoal machine production line in industry?

  The machine-made charcoal produced by the charcoal machine production line is more and more popular in the market because of its low cost and longer burning time than traditional charcoal. Machine-made charcoal is not only in people's lives It still plays a very important role in the development of society. In addition, the machine-made charcoal produced by the charcoal machine production line has a great influence on industrial production.

      1. Metallurgical industry

Previously, charcoal was used to smelt iron ore. The pig iron smelted with charcoal and coke has different structures and mechanical properties even if the chemical composition is the same. Pig iron smelted with charcoal generally has a fine-grained structure, compact castings, and no cracks. Pig iron produced with charcoal contains few impurities and is suitable for the production of high-quality steel.

 In the production of non-ferrous metals, charcoal is often used as a surface flux. When the non-ferrous metal melts, the surface flux forms a protective layer on the surface of the molten metal to separate the metal from the gaseous medium, which can reduce the splash loss of the molten metal and reduce the melting. The saturation of the gas in the material. A large amount of charcoal is also used in the production of crystalline silicon. The charcoal used in the production of crystalline silicon should not contain green char and excessive ash.

2. Manufacture of carburizing agent

All steel products that require high hardness and wear resistance on the surface and good toughness in the center must be carburized. The carbon-containing mixture used to carburize steel products is called a carburizing agent. The carburizing effect of simple charcoal is poor. Therefore, charcoal is commonly used as raw material, and then a certain amount of contact agent is added to make a carburizing agent.

3. Carbon disulfide production

Charcoal is a better raw material for manufacturing carbon disulfide. The charcoal used to make carbon disulfide should be hard, large in volume, low in ash and moisture, and high in fixed carbon. It takes about 0.5 tons of charcoal to produce 1 ton of carbon disulfide.

4. Suppression of charcoal bricks

The transportation of crushed charcoal is very inconvenient, and the use is also limited. The method of pressing charcoal bricks can make small value charcoal into high-quality fuel. Charcoal brick has the advantages of low hygroscopicity and water absorption, large specific gravity and high calorific value, and has high mechanical strength during use. The calcined charcoal bricks are smokeless when burned and do not produce carbon dust. Charcoal bricks can be used in metallurgy, mobile gasifiers, etc.
