Product Advantages

High-quality carburizes generally refer to carburizers that have been graphitized. Under high-temperature conditions, the arrangement of carbon atoms takes the microscopic form of graphite, so it is called graphitization. Graphitization can reduce the content of impurities in the carburizer, increase the carbon content of the carburizer, and reduce the sulfur content.

Manufacture And Use

Graphite carburizer is mainly used by major manufacturers in cast iron, steelmaking, and other industries. In these two industries, graphite carburizers have the function of induction electric furnaces, cupola-induction electric furnace double connection, and cupola melting. Graphite carburizer The agent is made by ferroalloy manufacturers using carbon materials as raw materials. It has the characteristics of high fixed carbon content, low ash content, low sulfur content, low volatile content, and few harmful impurities. It has a porous structure and is easy to dissolve in molten iron, making the carbon It has the characteristics of fast absorption speed, high absorption rate, no slag return, and stable carburizing effect. Using this graphite carburizing agent can greatly increase the amount of scrap steel. Reducing the amount of primary iron or using no pig iron can greatly reduce the cost of castings made by metallurgical material manufacturers. Cost of production.

Graphite carburizer is a metallurgical material that major metallurgical manufacturers continue to purchase. Every year, manufacturers purchase hundreds of tons of graphite carburizer. Some large manufacturers even purchase thousands of tons. Graphite carburizer is also a hot-selling product for export. First, it is difficult for metallurgical manufacturers to find a good graphite carburizer manufacturer and a graphite carburizer manufacturer with favorable prices. Therefore, major metallurgical manufacturers have been looking for good graphite carburizers in the industry. Carbon agent manufacturer.

Applications

It is widely used in the production of anode paste for electrolytic aluminum and prebaked carbon anodes, additives in the production of graphite electrodes and carburizes, and can also be used as fuel for metal silicon smelting.
Used as the basic raw material of carburizing agent and foaming agent.
Used as a basic chemical source of sodium hydride and high-purity CO in the chemical industry.

Uses of graphitized carburized

Carburizing agents are used during casting, which can greatly increase the amount of scrap steel and reduce the amount of pig iron or eliminate the need for pig iron. At present, most carburizers are suitable for electric furnace melting, and a small number of carburizers that absorb very quickly are used in cupola furnaces.

In the feeding method of electric furnace smelting, the carburizer should be put together with scrap steel and another charge. Small doses can be added to the surface of the molten iron. However, it is necessary to avoid feeding large quantities of materials into molten iron to prevent excessive oxidation, resulting in an insignificant carburizing effect and insufficient carbon content in castings. The amount of carburizing agent added is determined according to the ratio and carbon content of other raw materials. For different types of cast iron, different types of carburizing agents are selected according to needs. For the characteristics of the carburizing agent itself, pure carbon-containing graphitized substances are selected to reduce the cost. There are too many impurities in pig iron. Proper selection of carburizers can reduce casting production costs.
