As we all know, the ball caster heat treatment Yes Ball mill An important process for improving the performance of steel balls. But what are the methods and results of heat treatment? Let's get to know.
The purpose of heat treatment of austenitic stainless steel bead is to remove the stress magnetic force, because the steel ball will produce working magnetic force in the process of cold heading or grinding ball, the metallographic preparation will also slowly transform from austenite to martensite, and the corrosion resistance will also become worse, so the heat treatment can remove the magnetic force on the one hand, and can also transform into the original austenite on the other hand, Correct heat treatment, and the temperature of electric furnace rises to eight hundred and fifty Degree, stainless steel ball insulation is usually 1-2 Then pour it into cold water to cool it quickly, which usually removes the magnetism.
The purpose of martensitic stainless steel ball heat treatment is to improve the hardness, thereby enhancing the wear resistance of stainless steel ball and extending the service life of the workpiece: this type of stainless steel ball is high carbon and high chromium, and these two elements are a pair of contradictions. Because the carbon content and chromium content are too high, it is easy to cause uneven distribution of chromium, which affects the rust resistance of stainless steel.
At the same time, it is reminded that the results of heat treatment are different for steel balls made of different materials. Need to know more balls Mill The knowledge of steel ball can be: http://www.mrnmcl.com/NewsMore_1.html 。
