Rollers For Rolling Machine
When buying a tube shrinking machine, not only should you choose a high quality, high efficiency, stability and safety, it is also important to choose a suitable roller. Different materials of Roller have different characteristics and are suitable for the production of different electric heating pipes. Selecting suitable rollers can effectively increase production efficiency and reduce losses. Conversely, the use of unsuitable rollers can damage the rollers and greatly shorten the life of the machine.
Below is three main materials of Rollers that Jaye industry make for rolling machine:
[1.Tungsten Carbide Roller]
Tungsten carbide roller is an alloy material made of hard compounds of refractory metals and bonded metals through powder metallurgy.
Hardness: Heat Treatment (HRA) = 87 ° -90 °
Cemented carbide has the advantages of high hardness, wear resistance and longest service life
Suitable for small diameter and mass production
[2.High-speed steel roller / tungsten steel]
High speed steel, namely tungsten 18 chromium 4 vanadium (W18Cr4v),
Hardness: HRC Heat treatment: 63 ° -65
Features: The hardness is not much different from that of Tungsten carbide roller, but it is more suitable for processing larger diameter pipes. The price is also slightly lower than cemented carbide.
【3. Die steel / Cr12Mov】
The common name for mold steel is Cr12Mov, (Cr 12 Mo, V)
Hardness: HRC heat treatment 58 ° -61 °
The advantage of Cr12Mov is its high cost performance.
Cr12Mov is suitable for the production of a large number of electric heating tubes with a small amount of output.
