. After pouring the cooled casting from the mold is removed, a gate, riser and metal burrs Phi slit, sand casting sand casting also adhesion, it must be clean processes. Such work equipment shot blasting machine, gate riser cutting machines. Sand casting off the sand clean-up is a process of poor working conditions, so the choice modeling method of towing tank type, should be taken into account to create convenient conditions for the sand clean. Some castings for special requirements, but also after the casting process, such as heat treatment, shaping, anti-rust treatment, roughing, etc. Casting is more economic methods of rough shape, the shape of complex parts can show its economy. Such as automotive engine blocks and heads, ship propellers and exquisite works of art. Somewhat difficult to cut parts, such as gas turbine parts nickel-based alloy can not be formed without casting method. Casting process can be divided into three basic parts, namely, the cast metal preparation, mold preparation and casting process. Refers pouring cast metal castings for casting a metallic material, which is a metal element as a main component, and adding other metals or non-metallic elements and the composition of the alloy, the cast alloy customarily called streamers groove, mainly cast iron, steel and non-ferrous alloy casting. Not just a simple melting metal smelting, including the smelting process, so that the metal poured into the mold, the temperature, chemical composition and purity aspects are in line with expectations. For this reason the three slots in the smelting process to be performed in order to control the quality for the purpose of various inspection tests, liquid metal after reaching the specified target in order to allow the casting. Sometimes streamer tank repression, in order to achieve higher demand, but also by the liquid metal in the furnace after the furnace treatment, such as desulfurization, vacuum degassing, refining, processing, breeding or deterioration. Metal smelting equipment common cupola, electric arc furnace, induction furnace, resistance furnace, reflection furnace.
