Chamber type high-temperature electric heating furnace

Abstract

The invention provides a chamber type high-temperature electric heating furnace which comprises a furnace steel structure, a furnace door, a furnace liner, a furnace door lifting mechanism, a heating element and temperature detectors. The space in a furnace body is divided into twelve areas according to a furnace door wall, a rear wall, a furnace bottom wall, a left side wall and a right-side wall in the furnace body. One temperature detector and one component of the heating element are arranged in each area and connected in parallel and do not affect each other. The temperature detectors and the components of the heating element are connected to an outer control system. The chamber type high-temperature electric heating furnace has the advantages that uniformity of the temperature in the furnace body everywhere can be guaranteed, it is guaranteed that technological parameters in the production process are basically consistent, the chamber type high-temperature electric heating furnace does not have requirements of products for arrangement and brings great convenience to workers, the workload of the workers is reduced, and working efficiency is enhanced.

Description

technical field [0001] The invention belongs to supporting equipment in the machining industry, in particular to a chamber-type high-temperature electric heating furnace. Background technique [0002] For small forged workpieces, heat treatment before forging, and then machining, the quality of the heat treatment of the workpiece plays an important role in the machining accuracy and the performance of the workpiece, the heat transfer process in the high temperature heating furnace due to various positions Different temperature will lead to differences in temperature, which will bring certain difficulties to the processing process. The ideal state is that the temperature difference of each temperature range is ≤±5°C. However, the heating system in the furnace body is very Single, basically only one overall temperature can be set, and the four corners of each temperature are not considered. Contents of the invention [0003] In order to solve the above problems, the present...
