Description

Technical Field

[0002] Low nitrogen recarburizer is generally used in the manufacture of high-end precision castings. Such castings have very strict requirements on mechanical properties and must have very good hardness and tensile strength. Therefore, any defect factors of the product must be strictly controlled. If the nitrogen content in the recarburizer exceeds the standard, nitrogen pores and other related defects may occur, which will cause unpredictable losses and consequences. Nowadays, in the process of steelmaking, operators add recarburizer to the steelmaking rate in the specified process according to the steelmaking operation requirements. However, the existing recarburizer is dangerous if it is added manually during use, and mechanical addition generally directly puts the recarburizer into the steelmaking equipment at the same time, resulting in uneven addition. For this reason, a device for producing a low nitrogen recarburizer for smelting pure steel is proposed to solve the above problems. Utility Model Content
