Cryogenic furnace
Cryogenic treatment, which use liquid nitrogen (196 ℃) as a cooling medium to the metal material after quenching cooling process continues, reaches a certain temperature is far lower than the room temperature, prompted by conventional heat treatment after further into existence of residual austenite can make harden steel, enhancement of martensite, thus improving metal material performance.After cryogenic treatment, the abrasion resistance, toughness and dimensional stability of metal tools can be significantly improved, and the service life of workpieces can be doubled.
Product features of cryogenic furnace:
Cryogenic furnace body, door and heat insulation layer are made of AISI 304 stainless steel, and the heat insulation layer is multi-layer composite structure of imported ultra-low temperature heat insulation material.
The furnace is double sealed with imported special low-temperature resistant silicone rubber and special door buckle to ensure complete sealing. The box body is strengthened and strengthened to carry the weight of the workpiece reliably.
Special design can make the wind direction and air flow in the box not blocked to ensure the temperature in the box is consistent, the box cover is equipped with pneumatic power spring, convenient for the opening and support of the box cover.
The furnace is equipped with electrical interlock and alarm device to ensure safe use, user-friendly microcomputer operation interface, convenient for users to use.
Technical parameters:
Work temperature: Room Temp ～-190℃ adjustable
The lowest temperature in the box is – 195 C.
The maximum cooling speed 20 ℃ / min;
The temperature control accuracy — heating, cooling, constant temperature ±1℃；
Uniformity of temperature field–±5℃；
Door opening direction — up-lift (pneumatic cylinder opening and reduction motor configuration for user selection).

When used again, the modification effect of the workpiece will not be invalidated, and the shape and size of the workpiece will not change, but also enhance the dimensional stability and reduce the quenching stress;Simple process system, low power consumption, not limited by the shape and size of the workpiece, easy to operate;No environmental pollution, is a safe environmental protection technology.Since the appearance of cryogenic technology, it has attracted great attention from the scientific research and industrial circles. It has been applied in the modification of cutting tools, measuring tools, molds and precision parts, such as the nozzle of oil pump, the turboshaft of engine, rollers, valves, gears and springs.The application of cryogenic modification technology is gradually receiving high attention from the business community and developing very rapidly. The experimental results and achievements obtained so far show that cryogenic modification technology can be applied in the following aspects:
Increase the service life of HSS cutting tools, cutting tools and measuring tools;
Increase the service life of carbide tools and cutting tools;
Increase the life of carbide drill bits and tools;
Performance improvement of diamond manufactured goods, such as synthetic diamond heat stability, synthetic diamond mine drill bit, diamond Φ 105 mm blade etc performance improvement;
The anvil performance of diamond hot press is improved;
Dimensional stability of assembly parts of precision machinery;
Improved performance of carbon fiber;
The service life of nozzles, springs, gears and bearings is improved;
The service life of hot mold and cold mold is increased in the machinery manufacturing industry.
