Information
Common heat-resistant steels need to be cast under high temperature conditions, so they need sufficient anti-oxidation, corrosion and wear resistance. If there is segregation in product material or quality, they cannot achieve the ability just introduced. In the process of processing, not only good materials should be selected, but also heat treatment must be carried out after the product is formed.
 
The heat treatment of heat-resistant cast steel needs multiple steps, such as cleaning, charging, preheating, heating and cooling, so as to make the product reach the desired state. Some operations in this process still need special emphasis, such as preheating and cooling process of bearing pedestal of coal mill. Preheating is carried out for castings with complex and large changes in section, mainly to reduce the residual stress in the later stage.
 
When heating, there must be a heating working mode. For example, if the groove on the product cannot pass through the hole, it cannot be heated in the salt bath furnace. It is necessary to ensure that there is sufficient holding time. The same way is used to cool the casting of heat-resistant steel, and the place and time are reasonably controlled.
