Process requirements for carbon steel valve castings in processing

Cooling is an important step in the machining of carbon steel Castings.

1. When the medium carbon steel castings are air-cooled, they should be scattered in a dry place at room temperature;

4. For welding accessories made of medium carbon steel castings, the waiting time between welding and subsequent heat treatment processes should not exceed 4 hours.

At present, it mainly produces single large steel castings below 6T, and single steel ingots below 3T, such as large gear rings and sliding tracks; grinding discs and rollers for vertical mills; supporting wheels and tyres for rotary kilns; metallurgy and ceramics Industry racks; shipbuilding parts, auto parts, boxes, shells, hammers, drills and other products to meet the needs of different industries.
