Above the water-cooled crystallizer, install a heat-preserving cap made of insulating film material, also called hot top cap, pouring cup. The requirements for the hot top cap are no chemical reaction with molten aluminum, no moisture absorption, no oil absorption, no wetting to molten aluminum, high-temperature resistance, good insulation performance, thermal shock resistance, good strength, […]
When casting with the new hot top casting equipment, the high temperature melt in the distributing launder directly rushes to the center of the liquid cavity of the ingot, thus forming a deep and sharp liquid cavity. There is a large tensile stress at the bottom of the liquid cavity, which is easy to cause […]
