Ultra-cold treatment for carbide
In the ultra-cold treatment process, the internal stress in the cemented carbide is effectively adjusted, the tensile stress generated by cobalt is reduced, the resistance to microcracks is enhanced, the microcrack is effectively reduced, and the fatigue strength is improved. Resilience, while enhancing the bonding properties of cobalt to tungsten carbide, effectively reducing the peeling of carbides, and effectively improving the wear resistance. The cemented carbide that does not undergo tissue deformation can significantly increase the service life of the material workpiece after the DeepCryogenic Treatment. The exact structure of the cemented carbide is more dense, while promoting aging and plastic deformation. Impedance, in addition to a 30% to 5 times increase in life in a single use, the carbon layer is increased from 0.02-0.05mm to 0.08-0.13mm, which can significantly reduce the amount of re-grinding.
Ultra-cold treatment for aluminum alloy
After solid solution treatment with duralumin, the DeepCryogenic Treatment can improve the overall mechanical properties by promoting aging and greatly eliminating residual stress. At present, there are many cases in which the ultra-cold treatment is used to improve the performance of aluminum alloys in the foreign machinery industry. Most of the materials subjected to ultra-cold treatment are 7075 and 6061. In particular, the use of aluminum alloys in the high-speed operation of mechanical parts after the ultra-cold treatment life is more significant.

Flexible lift gate is a flexible soft curtain door, inside and outside the two curtains, curtains used between the aluminum beams connected with a vertically movable rail, the roof beams have levels not in the same straight line and hangar large plants in particular be applicable. Flexible lift door installation does not take up interior space in the hole inside. When the fiest move to open the door, and finally superimposed over the hole. Off event curtain rail first and then fall down until it is completely closed.
