Monitoring and operating three-chamber vacuum furnace

Abstract

The invention relates to a monitoring and operating three-chamber vacuum furnace, belonging to the technical field of vacuum furnaces. The monitoring and operating three-chamber vacuum furnace comprises a cooling chamber, a heating chamber, a preparation chamber, a vacuumizing mechanism and a monitoring and operating system, wherein both sides of the heating chamber are respectively connected with the preparation chamber and the cooling chamber through a chamber wall which is provided with an oil isolating door; the cooling chamber comprises a gas quenching chamber and an oil quenching chamber, and an inflating quick-cooling mechanism is arranged on the upper part of the gas quenching chamber, and an oil quenching oil tank with a stirrer is arranged on the lower part of the oil quenching chamber; a gas convection circulating mechanism is arranged on the heating chamber, and a heat isolating layer, a vacuum layer and a stainless steel shell are sequentially arranged in the heating chamber and the heat isolating door from the inside to outside of the heating chamber. The monitoring and operating three-chamber vacuum furnace provided by the invention is safe in quenching oil and uniform in heating materials, and also is good in heat isolating effect and high in product quality. Energy resources can be saved, and meanwhile, the processing efficiency is high.

Description

technical field [0001] The invention relates to a monitoring and operating three-chamber 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 ...

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 uneven heating of the material, and a good processing effect cannot be achieved.

[0005] 3. The heat insulation effect of the furnace wall in 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. The vacuum furnace of this design needs to open the heating chamber when the material is heated and processed. Therefore, every time the material is processed, the heating chamber must be evacuated and heated again, which wastes a lot of energy and is uneconomical and ineffective. Environmental friendly

[0007] 5. 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
