What are the methods for solidifying large stainless steel castings?

Large stainless steel castingsThe solidification method is as follows:

1. Paste solidification: The crystallization temperature range of the alloy is very wide. After solidification for a period of time, there is no solid layer on the surface of the large stainless steel casting, and the solidification zone runs through the entire section, first pasting and then solidifying.

2. Intermediate solidification: The solidification of most alloys is between layer-by-layer solidification and paste solidification.

3. Layer-by-layer solidification: Metal and eutectic alloys have no solidification area during the solidification process, and the cross-section liquid and solid phases are clearly separated. As the temperature decreases, the solid layer increases and the liquid phase layer decreases in the middle.
