Selection of cold iron materials for stainless steel precision casting

To improveStainless steel precision castingFor the local cooling rate, a kind of chilling agent called cold iron is placed in the cavity and the working surface. In the production of stainless steel precision casting, the method of combining cold iron, gating system and riser is often used to control the solidification process of castings to obtain qualified castings.
There are many materials that can be made into cold iron for precision cast stainless steel cold iron. All metal and non-metal materials can be selected from materials with higher heat conductivity and greater heat storage coefficient than sand materials. Commonly used cold iron materials are cast iron, aluminum alloy, graphite, copper alloy and so on. Cast cold iron has a large heat storage coefficient, can absorb more heat, and has a strong chilling capacity. Casting stainless steel precision cast iron with cold iron is easy to operate and low in cost. It is widely used in the production of aluminum alloy and magnesium alloy precision casting.
For stainless steel precision casting, all of us should choose the right method when choosing cold iron materials. It is what we need to choose a satisfactory casting method that suits us.
