The preheating heat treatment furnace is used to heat materials to the desired temperature level before the heat treatment process. Preheating furnaces are especially used in metalworking processes to prepare the material for subsequent heat treatments, such as hardening or tempering. Preheating ensures a more homogeneous heat distribution, prevents the formation of internal stresses, and reduces the risk of brittleness during the process. Preheating heat treatment furnaces are typically used before processes like die casting, welding, and other metalworking applications to ensure the material is uniformly heated, thereby enhancing the quality of the process.
