An energy-saving heat treatment furnace

Abstract

The invention discloses an energy conservation heat treatment furnace which comprises a base; a door hinged with the base is formed in the front surface of the base; a furnace body is fixed at the upper end of the base, and comprises two side plates and a top plate; coiled water pipes are arranged in the side plates; a coiled pipe B is arranged in the top plate; heat insulation layers are fixedlyarranged on the inner sides of the side plates, and are arranged above the bottom end of the interior of the furnace body; a plurality of arc-shaped heat-resistant bricks are fixed between the heat insulation layers; heating layers B are fixed at the outer ends of the heat-resistant bricks; and heating light-emitting pipes fixed to the side surfaces of the heat insulation layers are arranged between the heat-resistant bricks correspondingly; and a heating layer A is fixed at the lower end the top plate. The heat-resistant bricks are arc-shaped, so that shaft parts cannot roll; with the adoption of the multiple heat-resistant bricks, multiple parts can be contained; heat generated by the energy conservation heat treatment furnace is used for drying, and can also be provided to a heat supplydevice in a factory building; and the heat treatment furnace is green and environment-friendly and facilitates energy conservation and emission reduction.

Description

technical field [0001] The invention relates to the field of heat treatment furnaces, in particular to an energy-saving heat treatment furnace. Background technique [0002] Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing techniques, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but changes the microstructure inside the workpiece or changes the chemical composition of the surface of the workpiece. , to give or improve the performance of the workpiece. It is characterized by improving the intrinsic quality of the workpiece, which is generally not visible to the naked eye. In order to make metal workpieces have the required mechanical properties, physical properties and chemical properties, in addition to reasonable selection of materials and various forming processes, heat treatment processes are often essential. Steel is the most widely used material i...

Problems solved by technology

[0003] Most of the heat treatment furnaces currently used are normal heat treatment furnaces. During heat treatment, the furnace will generate a lot of heat. Only a small part of the heat is heated to the parts, and most of it is lost in the atmosphere, which is very wasteful. Unnecessary expenses for the factory
