Nonferrous metal smelting refers to the process of refining and processing non-ferrous metals(such as copper, aluminum, nickel, zinc, etc.). Leo refractory materials play an important role inthe nonferrous metal smelting process. They can not only play the role of fireproof and heatinsulation, but also resist the erosion of high temperature and corrosive gases. Leo refractoryinsulation materials are often used in the lining and furnace walls of smelting equipment formetals such as aluminum, copper, lead, and zinc, Leo refractory insulation materials are suitablefor the furnace door seals, furnace curtains, and kiln roof insulation of various nonferrous metasmelting kilns, Leo refractory insulation materials are suitable for the furnace door seals, furnacecurtains, and kiln roof insulation of various nonferrous metal smelting kilns.
