A monitoring operation vacuum furnace

Abstract

The invention relates to an operation monitored vacuum furnace, which belongs to the technical field of operation monitored vacuum furnaces. The furnace comprises a cooling chamber and a heating chamber as well as an operation monitoring system, wherein the cooling chamber and the heating chamber are isolated through a partitioning wall; a thermal insulating door is arranged on the partitioning wall; the cooling chamber comprises an air quenching chamber and an oil quenching chamber; an air inflation rapid cooling mechanism is arranged at the upper part of the air quenching chamber; an oil quenching tank with a stirrer is arranged at the lower part of the oil quenching chamber; the heating chamber is provided with a gas convection circulation mechanism; a thermal insulating layer, a vacuum layer and a stainless steel shell are sequentially arranged on the heating chamber and the thermal insulating door from the inside of the heating chamber to the outside; the operation monitoring system is connected with the air inflation rapid cooling mechanism, the vacuuming mechanism, a heating tube, a thermal insulating door lifting mechanism, the stirrer, the gas convective circulation mechanism and a material frame moving mechanism. The operation monitored vacuum furnace is safe in oil quenching, ensures uniform heating of materials and has a good thermal insulation effect.

Description

technical field [0001] The invention relates to a monitoring and operating vacuum furnace, which belongs to the technical field of vacuum furnaces. Background technique [0002] At present, the existing vacuum furnace includes a cooling chamber and a heating chamber, and the cooling chamber and the heating chamber are separated by a partition wall; a gas quenching chamber and an oil quenching chamber are arranged inside the cooling chamber, and the gas quenching chamber is provided with an air-filled quick-cooling mechanism. source, while the oil quenching chamber performs oil quenching through the oil quenching tank. The inside of the heating chamber includes a heating chamber platform and a material frame. The material frame is placed on the heating chamber platform. At the same time, one or more heating tubes are evenly arranged in the heating chamber along the circumferential direction, and a vacuum mechanism is arranged outside the heating chamber. There is an entrance...

AI Technical Summary

Problems solved by technology

[0003] 1. During oil quenching, because the processed materials are put into the oil quenching oil tank, the oil surface is heated unevenly and the oil splashes, so accidents are prone to occur

[0004] 2. The inside of the heating chamber is statically heated by the heating tube, so it is easy to cause the material to be heated unevenly, and a good processing effect cannot be achieved.

[0005] 3. The heat insulation effect of the furnace wall of the heating chamber of this design is not good, and the temperature between the cooling chamber and the heating chamber cannot achieve good heat insulation, so the heat dissipation is serious and the energy consumption is high

[0006] 4. When processing materials, this kind of heating furnace can only be processed manually, so its labor cost is high. At the same time, due to the limitation of workers' skills, the various processes cannot be well connected during processing, resulting in processing There are many defective products after the material
