Indoor low-temperature electric heating furnace

Abstract

The invention provides an indoor low-temperature electric heating furnace comprising a furnace door, a furnace body steel structure, a furnace lining, a furnace door lifting mechanism, a working area, and a series of heating elements arranged inside a furnace body, wherein the indoor low-temperature electric heating furnace also comprises a plurality of axial flow fans; the axial flow fans are embedded in the upper part of the furnace body steel structure; a grid plate is arranged at the front end of each axial flow fan; each grid plate is provided with a plurality of air guide outlets according to a left-middle-right order. The indoor low-temperature electric heating furnace provided by the invention has the beneficial effects that the certain gas convection can be ensured at each corner inside the furnace body in the production process, so as to ensure the uniformity of the temperature. Thus, the stability of the production of processing components is improved, and the stability of a technology is met.

Description

technical field [0001] The invention belongs to supporting equipment in the machining industry, in particular to a chamber-type low-temperature electric heating furnace. Background technique [0002] For small forged workpieces, annealing treatment is required after forging, and then machining is performed. The quality of heat treatment of workpieces plays a vital role in machining accuracy and performance of workpieces. Low-temperature electric heating furnaces are quite difficult to design and manufacture. On the one hand, it is necessary to consider that the workpieces are placed in a small concentration, and the temperature uniformity is difficult to meet the process requirements. On the other hand, the space specific efficiency of the heat treatment furnace is large. Contents of the invention [0003] In order to solve the above problems, the invention provides a chamber-type low-temperature electric heating furnace, the specific technical scheme is as follows: [00...
