In the process of casting steel parts, the problem of porosity shortcomings or insufficient Angle positioning is found. If this steel casting part is used for a long time, the case will be broken directly. At this time, you can use the method of slag pot heat treatment to solve these problems. The following is the knowledge of steel casting heat treatment:

Because the cast steel has defects such as pores, shrinkage holes, shrinkage porosity, coarse grain size, uneven organization, residual internal stress, and its strength and toughness will be directly reduced, thus affecting the subsequent processing process.

In order to refine the grain and uniform structure and eliminate the internal stress of steel castings such as slag pots, normalizing or annealing treatment is carried out. Because normalizing can improve mechanical properties more than annealing, and can reduce costs, it is widely used by cast steel manufacturers. However, because the internal stress generated after normalizing treatment will be larger than the annealing process, it is more suitable for large steel casting parts with a carbon content of less than 35%, which is a problem that needs special attention from steel casting manufacturers.

The equipment used in the steel casting plant is generally open hearth furnace, electric arc furnace, induction furnace, Xinxiang Great Wall steel casting is the use of electric arc furnace for steelmaking, which can quickly melt a variety of charges, the temperature is also easy to adjust and control, to meet the needs of different types of steelmaking, but also deoxidize.
