Ultra Cold Small Iqf Tunnel Freezer 800mm 300KGS/H 500KGS/H

Advantages of cryogenic treatment of cold rolls:

1. Significantly increase the depth of the hardened layer of induction hardening, and can withstand multiple grinding of the fatigue layer
2. The hardness gradient is more uniform and reasonable
3. Abrasion resistance is significantly improved
4. The distribution of roll stress is more reasonable, and the fatigue life is improved

5. It can be used for finishing rolls to roll out a better surface condition

The cryogenic treatment of the cold roll is to reduce the retained austenite and improve the wear resistance and life. Dejieli's large programmable cryogenic box uses liquid nitrogen to vaporize and cool, avoiding temperature shock; the temperature control accuracy of the cryogenic box is ±1℃, and the temperature The uniformity is ±3℃, and the lowest temperature reaches -196℃, which can provide a lower and more uniform treatment temperature and accurately control the cryogenic treatment process; the cryogenic box is sealed reliably, reducing the consumption of liquid nitrogen; the nitrogen is non-toxic and harmless Any safety hazards. The modular combined cryogenic box can completely solve the problems of traditional technology and is the best solution for roll cryogenics.
