Application of graphite recarburizer binder in metallurgical industry

Graphite classification and demand

In recent years, benefiting from the increase in the production of power batteries brought about by the demand for new energy vehicles, the global artificial graphite market demand has increased year by year, and artificial graphite has become the most important material in my country's negative electrode materials. reached 265,000 tons.

Natural flake graphite is a product after deep processing such as ore mining, flotation, drying, sorting, purification, pulverization, etc., while artificial flake graphite is a product of petroleum coke graphitization.

Graphite recarburizer binder

Graphite recarburizer binder is made up of polymer materials and a variety of chemical raw materials through the polymerization reaction. It is not only suitable for the molding and granulation of various ore powder raw materials in the metallurgical industry, but also for the molding and granulation of iron-containing dust and sludge waste; it can solve the strict requirements on the raw material grade of iron ore powder in the existing sintering plant, the serious decline in the grade of sintered pellets, and the consumption of iron ore. Compared with the traditional use of bentonite, it has the characteristics of strong cohesion, improved pellet grade, and reduced energy consumption.

Graphite ball application

1. Cold-pressed pellets are made of graphite ore powder, coke powder, solvent, etc., which can be directly smelted in the furnace. Large blast furnaces can be used as ingredients, and the coke powder in the cold ball can replace part of the expensive coke, thereby reducing the production cost. In addition, replacing part of the existing charge with the cold ball can increase the blast furnace output and reduce the coke ratio. The production process of cold-pressed pellets is pollution-free, thus solving the pollution problem caused by sintering. It is an ideal project for the technological transformation of small and medium-sized blast furnaces.

2. The rolled steel skin, dust sludge, etc. produced in the process of steel rolling and steelmaking are made into cold-pressed pellets, which can be directly added to converters and electric furnaces as slagging and dephosphorizing agents and coolants for steelmaking. This process not only recovers part of the metal It also solves the problem of insufficient scrap steel in steel mills, improves the quality of steel, and reduces the cost per ton of steel.

3. The cold-pressed pellets made of iron-containing materials, coke powder, flux, etc. have self-reducing properties, and the pellets can be directly added to the iron furnace for smelting. It has an adverse effect on the operation of the iron furnace, greatly reduces the production cost, improves the quality of the castings, and thus enhances the competitiveness of the product.
