Industrial Furnaces

Industrial furnaces are required for the production of glass, cement and ceramics, in foundries and for the heat treatment of metals, among other things. The construction of industrial furnaces poses a particular challenge for the materials used. They must be able to withstand very high temperatures (600 °C to 1200 °C), be wear-resistant and have a high level of chemical resistance. They are often exposed to rapidly changing temperatures. Heat-resistant and high-temperature-resistant stainless steels are able to withstand these conditions. A high carbon content and the alloying elements chromium, nickel, aluminium and silicon ensure that strength is maintained under the stresses prevailing during operation. The composition of heat-resistant and high-temperature-resistant stainless steels is precisely tailored to the intended temperature ranges and the process chemicals used. The operating conditions are decisive for the selection of the appropriate material.
