Heat treatment refers to a metal material that changes the chemical composition and structure of the surface or interior of the material in a solid state by means of heating, heat preservation and cooling to obtain the required properties.
processing technology. Heat treatment is one of the important processes in the manufacturing process of mechanical parts and tools and molds. Its processing process is generally divided into three steps: heating, heat preservation, cooling, special circumstances
Under this condition, some will directly skip the heat preservation step and proceed directly to the last step-cooling treatment.
The biggest advantage of the heat treatment process is to maximize its performance without changing the shape and overall chemical element composition of the metal workpiece. The heat treatment process is a
The traditional metal processing technology has a long history in our country, which can be traced back to the Stone Age.
