What is a vacuum heat treatment furnace
Vacuum heat treatment is a comprehensive technology combining vacuum technology with heat treatment. It refers to all and part of heat treatment process carried out in vacuum. China divides vacuum into low, medium, high and ultra-high vacuum. At present, the working vacuum of most vacuum heat treatment furnaces ranges from 1.33 to 1.33 x 10 -sup3; Pa.
Vacuum heat treatment can achieve 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 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. Generally speaking, the processed workpiece is heated slowly in the furnace, the difference of internal heat temperature is small, and the thermal stress is small, so the deformation is small. The qualified rate of products is high. The utility model can reduce the cost and has the function of degassing, thereby improving the mechanical performance and service life of the work. Good working environment, safe operation, no pollution and pollution. The treated workpiece has no danger of hydrogen embrittlement. It can prevent surface hydrogen embrittlement of titanium and refractory metal shell. The vacuum heat treatment process has good stability and repeatability. With these advantages, the development of vacuum heat treatment equipment and technology has been paid more and more attention and applied more and more widely.
Our company produces vacuum heat treatment, which integrates control system and furnace, with compact and beautiful structure. The furnace lining is made of high purity alumina ceramic fiberboard, which has small heat storage, good heat preservation and energy saving effect, light weight and small space occupation. The shell adopts double-layer air cooling structure to ensure that the surface temperature of the shell is close to room temperature. The temperature control system adopts intelligent instrument with industrial accuracy of 0.2 level, PID control and 51-stage programmable automatic control. The vacuum furnace is widely used in universities, scientific research institutes and enterprise laboratories. It burns metal, non-metal and other compound materials. Ideal equipment for junction, melting, analysis and development.
Vacuum heat treatment uses alumina fiber as furnace lining, silicon carbon rod or silicon molybdenum rod as heating element. Distribution of diffusion pump or molecular pump vacuum unit. It is widely used in heat treatment and copper welding of metal materials in high vacuum, reducing and protective atmosphere. Externally closed vacuum tank with water cooling system, the whole machine has novel structure, easy operation and affordable price.
