The Design of the Furnace for Heat Treatment by Electric
Abstract: Metal heat treatment is one of the important processes in the manufacture, compared with other processing, heat treatment is generally not change the shape of the workpiece and the overall chemical composition, but rather by changing the internal microstructure of the workpiece, or a change in the chemical composition of the surface of the workpiece, conferred or improve the performance of the workpiece. In industrial developed today, the power has been widely used in various industries, as a controllable clean energy, is also applicable to the heat treatment process, and does not generate a large amount of flue gas, can effectively reduce the flue gas heat away losses. This article is the design of the electric heating heat treatment furnace, It includes selection furnace, heat treatment time of the workpiece calculated stove specifications, power calculation of the electrical installation of the furnace, the furnace wall masonry material selection and calculation, related to the calculation of the heating element specifications, drawings and other .
Keywords: heat treatment; resistance furnace; heating time; install the power
