What’s vacuum gas quenching
Vacuum gas quenching is the process of heating the workpiece under vacuum, and then cooling it quickly in the cooling gas with high pressure and high flow rate, so as to improve the surface hardness of the workpiece.
Compared with ordinary gas quenching, oil quenching and salt bath quenching, vacuum high-pressure gas quenching has obvious advantages: good surface quality, no oxidation and no carburization; Good quenching uniformity and small workpiece deformation; Good controllability of quenching strength and controllable cooling rate; High productivity, saving the cleaning work after quenching; No environmental pollution.
There are many materials suitable for vacuum high-pressure gas quenching, mainly including: high-speed steel (such as cutting tools, metal molds, dies, gauges, bearings for jet engines), tool steel (clock parts, fixtures, presses), die steel, bearing steel, etc.
Paijin Vacuum gas quenching furnace is a vacuum furnace consisted by furnace body,heating chamber,hot mixing fan,vacuum system,gas filling system,vacuum partial pressure system,electric control system,water cooling system, gas quenching system, pneumatic system,automatic furnace feeding trolley and power supply system.
Application
Paijin Vacuum gas quenching furnace is suitable for quenching treatment of materials such as die steel, high-speed steel, stainless steel, etc; solution treatment of materials such as stainless steel, titanium and titanium alloy; annealing treatment and tempering treatment of various magnetic materials; and can be used for vacuum brazing and vacuum sintering.
Characteristics
1. High cooling speed: by using high efficiency square heat exchanger, its cooling rate is increased by 80%.
2. Good cooling uniformity: Air nozzles are evenly and staggered set all around the heating chamber.
3.High Energy Saving: Its air nozzles will automatically close in heating process, makes its energy cost 40% less.
4. Better temperature uniformity: its heating elements are evenly set all around the heating chamber.
5. Suitable for various process environments: Its heating chamber’s insulation layer is made by composite hard insulating layer or metal insulating screen, suitable for various environments.
6. Smart and easy for process programming, stable and reliable mechanical action, automatically, semi-automatically or manually alarming and displaying the faults.
7. Frequency conversion control gas quenching fan, optional convection air heating, optional 9 points temperature survey, partial pressure quenching and isothermal quenching.
8. With whole AI control system and an extra manual operating system.
