Selection of cold iron materials for stainless steel casting

In order to increase the local cooling rate of stainless steel castings, the chilled material placed inside the cavity and working surface is called chilled iron. In stainless steel 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 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 cold iron has a larger heat storage coefficient, can absorb more heat, and has a stronger chilling capacity. Stainless steel cast iron, cold iron is easy to manufacture and low in cost, and is widely used in the production of aluminum alloy and magnesium alloy casting.

When we all choose the cold iron material for stainless steel casting, we should choose the correct method. It is what we need to choose our suitable and satisfactory casting method.
