Problems solved by technology

[0005] What the present invention aims to solve is the problem that the internal temperature of the furnace chamber is not uniform during the firing process of the ordinary high-temperature resistance furnace, which produces different thermal effects on the workpiece and the firing atmosphere in the furnace cannot be effectively adjusted. It provides a high-temperature sintered resistance furnace

Abstract

A high temperature sintering resistance furnace comprises a hearth with an insulation layer, wherein the lower part of the hearth is supported by a base, kiln furniture is arranged in the hearth, and an in-furnace hot air circulation system and a rotating device for bearing a workpiece are arranged in the hearth. The uniformity of temperatures at different parts of the high temperature sintering resistance furnace is well guaranteed, particularly when a large batch of workpieces are loaded, the thermotechnical effect deviation in the traditional furnace is eliminated through force convection and kiln furniture rotation, and meanwhile, the sintering atmosphere in the furnace is effectively regulated and improved andthe sintering quality of the workpiece is improved; and the temperature uniformity is excellent, the furnace volume can be sufficiently used, the yield of single furnace can be substantially improved, the energy consumption of single product is reduced, and the economic benefit and the practical value are very high.

Description

technical field [0001] The invention belongs to the technical field of thermal kilns and can be used for firing vitrified bond grinding wheels and ceramic products. Background technique [0002] The resistance furnace system is used in periodic operation mode. It is used for elemental analysis and determination in laboratories, industrial and mining enterprises, and scientific research units, as well as heating for heat treatment such as quenching, annealing, and tempering of small steel parts. It can also be used for sintering, melting, and analysis of metals and ceramics. For medium temperature heating, the maximum firing temperature in the furnace can reach 1200 degrees Celsius. The shape of the electric furnace is rectangular, circular, etc. The furnace shell is made of high-quality steel plate folded and welded. The working chamber is a furnace made of refractory material. The heating element is placed in it, and the furnace and the shell are built with insulation mater...
