Casting heat is a kind of subacute scalding reaction caused by the high dispersion of zinc oxide smoke during copper smelting. Many people report that the smoke of metal oxides such as lead, tin, antimony nickel can also cause the disease. To avoid the free emission of metal smoke is a root pressing method to prevent casting heat. In the actual operation of smelting casting, it is necessary to improve the sealing, install some dust remover equipment of exhaust system, purchase zinc oxide. Improving all-round natural ventilation wearing smoke protective masks can be taken as service countermeasures.

The casting process can be divided into three basic parts, namely, the advance preparation of casting metal, the advance preparation of metal mold of low-pressure casting parts manufacturers the solution of casting parts. Casting metal refers to the metal raw materials used for casting castings in casting manufacturing. It is an alloy composed of one metal element as the key component other metal non-metal elements added. The low-pressure aluminum casting manufacturers habitually call it casting alloy, the key elements are pig iron, steel casting casting non-ferrous plate alloy.
