Edit:Xiangyang Liqiang Machinery Co., Ltd.UpDate:2020-02-02

Stainless steel precision casting is a casting process with little or no cutting, and it is an excellent process technology in the foundry industry. When we all use stainless steel precision casting, how do we generally need to choose the cold iron material in stainless steel precision casting?

In order to increase the local cooling rate of the casting, the chilled material placed inside the cavity and the working surface is called cold iron. In stainless steel precision casting production, cold iron, pouring system and riser are often used together to control the solidification process of castings and obtain qualified castings.

The choice of stainless steel precision casting cold iron materials, there are many materials that can be used to make cold iron, and all metal and non-metal materials with greater thermal conductivity and heat storage coefficient than sand materials can be used. Commonly used cold iron materials in production include cast iron, aluminum alloy, graphite and copper alloy. Cast iron chilled iron is easy to produce and low in cost. It is widely used in the production of aluminum alloy and magnesium alloy precision casting. Especially when placed at the bottom or end of the casting to strengthen the solidification sequence of the casting, cast iron chilled iron is generally used.

We are all choosingStainless steel precision castingFor cold iron materials, we can choose according to the above selection methods, and choosing our suitable and satisfactory products is what we all need.
