Foundry heat is an acute fever reaction caused by inhalation of highly dispersed zinc oxide fumes generated during copper melting. It has been reported that metal oxide fumes such as lead, tin, antimony, nickel, etc. can also cause this disease. Preventing the escape of metal smoke is the fundamental way to prevent casting heat. In the smelting, casting and other operations, it is necessary to strengthen the sealing, install local exhaust dust removal equipment, and recover zinc oxide. Strengthening full ventilation and wearing anti-smoke masks can be used as complementary measures. With the advancement of science and technology and the vigorous development of the casting industry, different casting methods have different mold preparation content. Taking the most widely used sand casting as an example, casting preparation includes molding material preparation and molding and core making.
