Carbonizing agents are made from coal as raw materials, with high fixed carbon content, strong oxidation resistance, and low harmful element content. They are used as reducing agents in the smelting process. The supplier of carburetor pointed out that it is a type of carbon material added to compensate for the required carbon content in the molten steel. Adding it can improve the performance of steel. It is a key additive for producing high-quality steel.
With the continuous development of science and technology, various processing technologies are also being optimized. Many products may experience the phenomenon of survival of the fittest during use, so good products will leave. At the same time, optimizing processing technology can improve production efficiency and product quality. During the normal blowing process, the oxidation process of carbon in molten iron is the main chemical heat. Therefore, increasing the temperature of molten iron from below 1400 ° C to above 1600 ° C can reduce the carbon content in the process from 4% to 0.2%, or even 0.1%. The carbon content cannot meet the requirements of most steel grades. Therefore, it is necessary to add graphite carburizing agent in the steel process to increase the carbon content of the steel and meet the requirements of national standards.
At present, carbon additive manufacturers point out that their demand in our market is relatively large, and it has a wide range of applications. In addition to the steel industry, it can also be used in industries in China's production field, playing a very important role in some smelting processes, such as electric furnaces and carbon., It is currently an indispensable refractory material in China.
The carbonizing agents used in steelmaking include graphite, charcoal, coke, etc. In the process of smelting medium and high carbon steel in an oxygen converter, the carbonization of low ash petroleum coke is generally used. The requirements for carburetors are high fixed carbon content, low ash content, low volatile matter, sulfur, phosphorus, nitrogen and other impurities, and moderate particle size after drying. The particle size is too fine, easy to burn, and floats on the surface of molten steel.
In China's steel and cast iron industries, in order to better ensure the good performance of smelting products during production and processing, carburetor factories often need to strictly control carbon content. As the name suggests, carburetor is used to increase the carbon content in molten iron. For example, it is commonly used in smelting furnace materials such as pig iron, scrap steel, return to furnace materials, and iron with high carbon content. However, compared to the higher part of scrap steel procurement price, increasing the supply of scrap steel, reducing the quantity of pig iron, and increasing carbon agent can play a role in reducing casting costs.
Therefore, in the steelmaking process, not only does graphite carburizing agent need to be used, but the demand for different types of steel and carburizing agent also varies. The quality of carburizing agent greatly affects the quality of steel, thus playing an important role in reducing the shrinkage of molten iron carburizing agent.
