Vacuum heat treatment furnace basic introduction


Vacuum heat treatment is a comprehensive technology combining vacuum technology with heat treatment, which refers to all and part of the heat treatment process in vacuum. Vacuum is divided into low, medium, high and ultra-high vacuum in China. At present, the vacuum of most vacuum heat-treatment furnaces is 1.33~1.33 * 10 ³ Pa. Vacuum heat treatment can realize almost all heat treatment processes, such as quenching, annealing, tempering, carburizing, nitriding, gas quenching, oil quenching, nitrate quenching, water quenching, vacuum brazing, sintering, surface treatment and so on. Vacuum heat treatment furnace has high thermal efficiency, can achieve rapid heating and cooling, can achieve no oxidation, no decarbonization, no carburization, can remove the surface of the workpiece phosphorus chip, and degreasing and degassing, so as to achieve a bright surface purification effect. Generally speaking, the processed workpiece is slowly heated in the furnace, the internal thermal temperature difference is small, the thermal stress is small, so the deformation is small. The product has a high pass rate. It can reduce the cost and degassing, thus improving the mechanical performance and service life of the work. The working environment is good, the operation is safe, and there is no pollution and public hazard. There is no danger of hydrogen embrittlement in the treated workpiece. It prevents hydrogen embrittlement on the surface of titanium and refractory metal shell. The vacuum heat treatment process has good stability and repeatability. This series of advantages, the development of vacuum heat treatment equipment and technology has been more and more attention and application more and more widely.
 Generally, metal materials are heated in an air furnace. Oxygen, steam, carbon dioxide and other oxidizing gases exist in the air. The oxidation of these gases with metal easily causes the heated metal surface to produce oxide film or oxide scale, completely losing the original metallic luster. At the same time, these gases react with carbon in metal to decarburization on the surface. If the furnace contains carbon monoxide or methane gas, it will also increase the carbon content on the surface of the metal. For Ti, Zr, W, Mo, Nb and Ta with very active chemical properties, heating in an air furnace not only produces oxides, hydrides and nitrides, but also absorbs these gases and diffuses them into the metal, which seriously deteriorates the properties of metal materials. These defects, such as oxidation, decarbonization, carburization, inhalation and even corrosion, are sometimes unavoidable when heated in a controlled atmosphere furnace or salt bath furnace. In order to solve this problem, the usual way is to leave the machining allowance before the heat treatment of the workpiece, and remove the oxidation and decarbonization layer after the heat treatment.


Vacuum heat treatment furnace how much is the price?

It depends on the heat treatment process, the heat treatment equipment is different, the price is not the same. Like vacuum heat treatment, the price is high. Why is the price of vacuum heat treatment furnace so expensive?
 Vacuum heat treatment refers to all and part of the heat treatment process in a vacuum state. Vacuum heat treatment can achieve almost all of the heat treatment processes involved in conventional heat treatment, but the quality of heat treatment is greatly improved.
 Compared with conventional heat treatment, vacuum heat treatment can realize no oxidation, no decarbonization, no carburization, can remove the phosphorus chip on the surface of the workpiece, and has the function of degreasing and degassing, so as to achieve the effect of surface bright purification.
The high price of vacuum heat treatment is due to the expensive equipment and high energy consumption; the small weight of each furnace is due to the small vacuum chamber, easy to vacuum; vacuum heat treatment workpiece than ordinary heat treatment workpiece oxidation resistance and corrosion resistance, and the microstructure is more compact.
