Fabrication Method of Annealing Device

Quenching is a method of heat treatment of this metal material. It means that the metal material is slowly heated to the necessary temperature, maintained for a sufficient time, and then cooled by water at a suitable rate. Its purpose is to reduce the strength, improve the drilling process performance by the manufacturer of large pull-back device; remove internal stress, stabilize specifications, reduce the tendency of deformation and crack; optimize crystals, regulate mechanism and eliminate the shortcomings of mechanism. At present, the most extensive solution is to use full hydrogen bell furnace. During the whole process of quenching, radon gas is needed to maintain the raw materials, so that they are not oxidized by air, so that the surface of raw materials is bright, and the heat transfer efficiency is improved, thus enhancing the quenching capacity. However, the current quenching equipment has some drawbacks: 1. The annealing furnace can not block CO2 very well, which must endanger the reliability and reliability of high temperature quenching; 2. Radon gas is not uniform throughout the annealing furnace, and the fusion annealing furnace can not block CO2 very well. The raw materials at the lower part of the radon concentration in the annealing furnace are very capacitive. Easy to touch CO2 produces air oxidation, which ultimately prevents the raw material from exceeding the actual effect of quenching prediction and increases the cost of the company by raising the types of commodities concerned. 3. Radon is a flammable gas, which must be properly handled in order to prevent potential safety hazards in the work of workers.
