A melting furnace is a specialized device used to heat and melt various materials, primarily metals. It operates by using high temperatures to transform solid metal into a liquid state, making it easier to cast or mold into desired shapes. Commonly used in industries like manufacturing and recycling, melting furnaces can handle materials such as aluminum, copper, and steel. These furnaces come in different types, including electric arc furnaces and induction furnaces, each designed for specific applications. Safety is crucial when operating a melting furnace, as the extreme heat can pose risks. Proper training and protective gear are essential for workers in facilities that use these machines.
