RECARBURIZER

Recarburizer is an additive used in steelmaking. It is an indispensable raw material for the production of high-quality steel. In addition, it is also a raw material for the production of electrode paste. Graphite powder is used for pressing to form, which can greatly increase the amount of scrap steel, reduce the amount of pig iron or not use pig iron in the production of castings. In the electric furnace smelting, put the recarburizer in the middle, (place a part of the material in the furnace and then add the recarburizer) to add The measurement is 1-3% of the amount of metal. The characteristic of the recarburizer is that the carbon has a good absorption effect in the molten iron and does not return slag. The use of the recarburizer can greatly reduce the production cost of castings. Recarburizers belong to the raw materials for adding recarburization for steelmaking and ironmaking. High-quality recarburizer is an indispensable auxiliary additive for the production of high-quality steel.

1. Recarburizer for steelmaking
2. Recarburizer for cast iron
3. As a friction material: such as additives for brake pads
3. Types of recarburizers
1. Graphitized petroleum coke recarburizer: the calcined petroleum coke is used as a raw material, and the calcined petroleum coke is placed in a graphitization furnace, after high temperature graphitization, physical and chemical reactions occur, and sulfur and ash are removed. Sometimes called artificial graphite recarburizer, when used in recarburizer, it is often called ultra-low sulfur/low nitrogen recarburizer.
2. Calcined petroleum coke recarburizer: After low-sulfur petroleum coke is used as raw material, the petroleum coke is placed in a calciner, and after high temperature calcination at 1300℃, physical and chemical reactions occur and the moisture and volatiles in the petroleum coke are removed. The product.
3. Low-nitrogen recarburizer: applying a special production process, through multiple processes, the calcination temperature reaches 2400℃, the sulfur content (S) is reduced to below 0.05 (500PPM), and the nitrogen content (N) is reduced to 0.02 (200PPM) and increase the permeability of the carbon particle pores, thereby increasing the melting speed and absorption rate of the recarburizer in the molten steel, achieving the effect of high-efficiency recarburization.
