What is the specific process of casting steel?

Steel is different from iron, with a carbon content of 0.77% as the boundary.

There are many kinds of castings, which are traditionally divided according to modeling methods.

① Ordinary sand casting, also known as sand casting and sand turning, includes three types: wet sand mold, dry sand mold and chemically hardened sand mold. ② Special casting can be divided into two types according to molding materials: special casting with natural ore as the main molding material (such as investment casting, clay casting, shell casting, negative pressure casting, full mold casting, ceramic casting, lost foam casting, etc. ) and special casting with metal as the main mold material (such as metal mold casting, pressure casting, continuous casting, low pressure casting, centrifugal casting, etc. ).

According to the molding process can be divided into

1. Gravity casting: sand casting and hard mold casting. The molten metal is injected into the cavity by gravity. 2. Pressure casting: low pressure casting, high pressure casting. The molten metal is instantly pressed into the casting cavity by extra pressure.

Generally, people are familiar with rolled plates, steel pipes and wires, which are not cast.
