Blade Freezer

Product Detail

Blade freezer -45 degrees to -110 degrees cryogenic cold sources, blade freezer, now on behalf of the industrial production has played a huge role, replacing the old method of liquid nitrogen cooling, blade freezer with the Freon pressure mechanized shrink cooling, the provincial , the energy-saving, environmental protection, was ordered long cryogenic unit, -135 ? ~ -40. compared to the process used liquid nitrogen refrigeration costs by 5 to 8 times, and the the deep modern industrial Cooling treatment of choice. ? cryogenic liquid cold source, unit equipment imported semi-closed low-temperature screw compressor or piston compressor, the main components are internationally renowned brands, adopt advanced PLC and microcomputer control system, with stable performance, safe and reliable. Commonly used in the molds, cutting tools, measuring tools, scissors, saw blades, oil pump and nozzle, automotive bearings, micro motor shaft, roll, cryogenic valves, cryogenic treatment of first-class golf products, as well as low-temperature metal parts assembly process. Cryogenic memory metal, ceramic, nylon, carbon fiber, Teflon, vacuum contact electrodes, filament, plastic, etc. Also, I believe that with the development of science, cryogenic applications will become increasingly wide, is also widely used in the pharmaceutical, aerospace, military, petroleum, chemical industry, light industry, research and other processes require cryogenic cooling, refrigeration industry to meet the demand of the industrial production in the 24-hour continuous production process cold source.

After the cryogenic treatment of the blade refrigerating machine blades, bearings and other metal cutlery for regrinding then does not invalidate the modification effect of the workpiece, the shape and size of the workpiece only does not cause changes, but also enhance the dimensional stability and reduce the quenching stress the role; process system is simple, less power consumption, without workpiece shape and size restrictions, easy to operate; without any environmental pollution, safe and environmentally friendly technology. Cryogenic technology appeared attaches great importance to scientific research and industry, in a foreign country has been used in cutting tools, molds, precision parts, such as pump glib turboshaft engine, roll, valves, gears, modified springs and other artifacts. The modified cryogenic technology is gradually to get the business community attaches great importance to developing very rapidly, and has obtained experimental results and the results obtained show that the cryogenic modification technology can be applied in the following areas:

1, high-speed steel cutting tools, cutting tools, measuring tool life improved;

2, carbide cutting tools, cutting tool life improved;

3, carbide drill bit, drill the life expectancy has increased;

4 diamond manufactures performance improvement, such as synthetic diamond thermal stability improved the synthetic diamond mining drill bits, diamond F105mm blade performance improve;

5 diamond anvil pressing machine performance;

6, the size and stability of precision mechanical assembly parts;

7, the performance of the carbon fiber thread;

8, glib, springs, gears, bearing life improved;

9, the heat in the machinery manufacturing industry molds, cold work die life improve. Blade hardness value blade type micro hardness (HV) of the deep cold with not deep cold YW1 of Rockwell hardness (HRA) without cryogenic processing 1764.0 90 2263.7 92 after cryogenic treatment.

Blade freezer in the United States, the former Soviet Union, Europe and other countries not only cryogenic technology used in high-speed steel, bearing steel, tool steel, used to improve the wear resistance, toughness, and the overall service life of the material, also use cryogenic processing technology cryogenic modification treatment on the aluminum alloy, copper alloy, cemented carbide, plastics, rubber, asphalt, glass, etc., and also greatly improves the uniformity, dimensional stability, and improve the service life. Reasonable cryogenic treatment process can significantly improve YW1 carbide blade abrasion resistance. Microhardness and Rockwell hardness of the blade after cryogenic treatment improved significantly, indicating that the cryogenic treatment YW1 microstructure can be changed. X-ray diffraction analysis showed that after the cryogenic treatment, YW1 occurs more completely the binder phase of Co AE changes, this is a multi-type of the martensitic transformation.
