Technical Field

[0001] The utility model relates to the technical field of low-nitrogen carburizer production, in particular to a pulverizing device for low-nitrogen carburizer production. Background Art

[0002] Low nitrogen recarburizer is an additive used to increase the carbon content in castings, usually used in casting production such as ductile iron and gray cast iron. Its working principle is to increase the carbon content of the molten metal by adding carbon-containing substances to the molten metal, thereby improving the strength, wear resistance, corrosion resistance and other properties of the casting.

[0003] The main components of low nitrogen recarburizer are carbon and nitrogen. It is usually made of silicon carbide, graphite, coal powder and other materials as raw materials, and is made through high temperature melting, chemical reaction and other processes. Among them, the nitrogen content is low to avoid negative impact on the performance of castings. The method of using low nitrogen recarburizer is to add it to the molten metal during the melting process of the molten metal and stir it evenly. The amount of addition needs to be adjusted according to the requirements of the casting and the composition of the molten metal to ensure that the performance of the casting reaches the best state. The first step in the production of low nitrogen recarburizer is to crush the raw materials.
