How to solve the problem in the casting of the slag pot

Slag pot is an important equipment for steelmaking in the metallurgical industry, and its quality directly affects the production.

Large steel mills generally purchase large slag pots of more than 10m ³, whose size is difficult to control in super-large production, and the structure of its barrel-shaped parts is very easy to produce shrinkage or porosity at its root; at the bottom of the slag pot, there are four vertical angles. the root of the vertical angle produces large casting stress in the process of shrinkage, which is very easy to crack. Due to the large volume and surface area of castings, a large amount of gas will be produced in the pouring process, which is the difficulty in the casting process, which must be considered in advance and made up in the process.

Due to the need for frequent contact with high temperature smelting slag and easy to produce thermal fatigue, the casting is not allowed to have cracks, shrinkage, porosity, pores, sand holes, slag inclusion, cold insulation and other casting defects affecting quality.

Through the comprehensive analysis of the structure and process of large slag pot steel castings, combined with many years of casting technology and production experience, Kunfeng heavy Industry effectively prevented the occurrence of cracks and shrinkage, and produced qualified castings. it provides a reference method for the production of similar castings.
