In the smelting process of iron and steel products, the melting loss of carbon in molten iron is often increased due to factors such as smelting time, holding time and overheating time, resulting in a decrease in carbon content in molten iron, which leads to the carbon content in molten iron not reaching the expected theoretical value of refining.
In order to make up the carbon content lost in the process of iron and steel smelting, the added carbon-containing substances are called carburetors, which react with molten iron at high temperature to absorb oxygen in molten iron, thus increasing the carbon content in molten iron.
There are many kinds of carburizing agents, which can be divided into many types according to their different raw materials and production processes. Common carburant raw materials include wood carbon, coal carbon, coke, graphite and so on.
Application in iron and steel metallurgy: Using carburizing agent in iron and steel metallurgy can improve the thermal efficiency of smelting furnace, reduce smelting cost, increase supply and improve product performance. While using carburizing agent, we should also pay attention to the adjustment of its addition amount to avoid adverse effects on product quality.
Other application fields: Carburetors can also be used in casting, metallurgy, electronics, chemical industry, ceramics, and other fields. In these fields, the main function of a carburizing agent, such as petroleum coke for sale, is to increase the carbon content in products and improve basic properties like hardness, wear resistance, and corrosion resistance.
