Production Process Of Heat-Resistant Steel Castings

The production process of heat-resistant steel castings includes multiple stages such as raw material preparation, smelting, molding, pouring, and heat treatment. Smelting is a crucial step, determining the composition and purity of the molten steel. The molding stage requires selecting an appropriate molding method based on the casting's structure and shape to ensure dimensional accuracy and surface quality. During pouring, the temperature and pouring speed of the molten steel must be controlled to prevent defects such as cracks and porosity. Heat treatment involves heating, holding, and cooling to improve the microstructure and properties of the casting.
