Precautions for vacuum furnace experiment
Although the precautions of vacuum furnace have been said many times, today Nuotai Technology still needs to focus on the following points.
The vacuum furnace, as the name suggests, has a high vacuum value. Because of its circular structure, it can pump a very high vacuum value. Why is an atmosphere furnace necessary to own a vacuum furnace? This depends on the price. Assuming that the vacuum value required by the customer is not high and the atmosphere furnace can meet his regulations, how do you choose it? Besides, the atmosphere furnace is usually in the air while the air is discharged, and the maintenance gas can be used to prevent the atmosphere from entering the furnace, and it can fully meet the requirements of goods processing.
Matters that must be paid attention to in the laboratory of the vacuum furnace, the structure type of the vacuum furnace, the temperature control system, the heating process and the atmosphere in the furnace, etc., are all real damage to the product quality after the vacuum furnace is manufactured. In the forging heating furnace, increasing the temperature of the metal material can reduce the melting resistance, but too high temperature will cause the grains to oxidize or overburn, which will greatly harm the quality of the products in the vacuum furnace. In the whole process of heat treatment, assuming that the steel is heated to a certain point above the critical temperature and then suddenly cooled by cooling, the hardness and strength of the steel can be increased; assuming that the steel is heated to a certain point below the critical temperature and then slowly cooled, it can Make steel more tough.
The vacuum furnace usually consists of a furnace, an electric heating device, a vacuum system, a sealed furnace shell, a power supply system and a temperature control system. The sealed furnace shell is welded with carbon steel or stainless steel, and the joint surface of the detachable part is sealed with a vacuum sealing material. In order to prevent the furnace shell from deforming after heating and the sealing material from being heated to deteriorate, the furnace shell is usually cooled with water or air.
