Chemical heat treatment of steel castings
The chemical heat treatment of steel castings refers to placing the castings in an active medium at a certain temperature for heat preservation, so that one or several chemical elements can penetrate the surface. Chemical heat treatment can change the chemical compositio...Read more -
Surface Heat Treatment of Steel Castings
Surface heat treatment refers to the process of heat-treating only the surface layer of steel castings. Surface heat treatment can also obtain the required metallographic structure and mechanical properties. Commonly used surface heat treatment methods are: induction hea...Read more -
General Information of Heat Treatment for Steel Castings
The heat treatment of steel castings is based on the Fe-Fe3C phase diagram to control the microstructure of the steel castings to achieve the required performance. Heat treatment is one of the important processes in the production of steel castings. The quality and effec...Read more -
No-Bake Sand Casting Process
Sand molds used in sand casting are classified into three types: clay green sand, clay dry sand, and chemically hardened sand according to the binder used in the sand and the way it builds its strength. No-bake sand is foundry sand th...Read more -
Normalization Heat Treatment for Steel Castings
Normalizing, also known as normalization, is to heat the workpiece to Ac3 (Ac refers to the final temperature at which all free ferrite is transformed into austenite during heating, generally from 727°C to 912°C) or Acm (Acm is In actual heating, the critical temperature...Read more -
