Low-sulfur and Low-nitrogen Carburizer

Calcined anthracite, calcined anthracite coal, and electric calcined anthracite are used in iron and steel smelting, casting and friction materials.

As a coal-based recarburizer in the steelmaking process, the recarburizer is used in casting, which can greatly increase the amount of scrap steel and reduce or eliminate the amount of pig iron.In the feeding method of electric furnace smelting, the recarburizer should be put in together with scrap steel and other furnace materials.Adding can choose to add on the surface of molten iron. However, it is necessary to avoid feeding large quantities of materials into molten iron to prevent over-oxidation.Too much, the carburizing effect is not obvious and the carbon content of the casting is not enough. The amount of carburant added, according toThe ratio and carbon content of other raw materials are determined. Different types of cast iron, choose different models according to your needs carburant. The characteristics of the recarburizer itself choose pure carbon-containing graphitized substances to reduce excessive carbon dioxide in pig iron.Proper selection of impurities and recarburizers can reduce the production cost of castings.

Remark: Chemical composition and size can be optimized by the customers' requirements.
The main uses of petroleum coke are prebaked anode and anode paste for electrolytic aluminum, carbon industry production of carbon enhancer, graphite electrode, smelting industrial silicon and fuel, etc.

Among them, high-quality low sulfur coke (sulfur content is less than 0.5%) can be used to produce graphite electrode and carburizing agent. Low sulfur coke of general quality (sulfur content less than 1.5%) is often used to produce prebaked anode. Low quality petroleum coke is mainly used for smelting industrial silicon and producing anode paste. High sulfur coke is generally used as fuel in cement plants and power plants.

Calcined petroleum coke can be widely used in steel-making, chemical industry, building materials, casting materials, machinery, petroleum exploration and other industries.
