Adamite Steel Rolls high speed steel Work rolls of finishing stands for hot strip mills
HIGH SPEED STEEL ROLLS
◆ SUMMARY
The working layer of HSS rolls are made of alloy V, W, Nb and Mo, and shaped in Centrifugal Casting Machine, with spheroidal graphite cast iron in its core.
◆ ADVANTAGE
◇ HIGH HARDNESS
The hardness of roll working layer to reach as high as 80-85HSC with the control of element composition and heat treatment.
◇ GOOD WEAR RESISTANCE AT HIGH TEMPERATURE
It ensures good wear resistance at high temperature and uniform wear in the roll passes, as the important
metal elements are uniformly distributed in the martensitic structure, such as V (Vanadium), W (Tungsten), Nb (Niobium) and Mo (Molybdenum).
◇ IMPROVING OF SURFACE QUALITY OF ROLLED PIECE
◆ APPLICATION
◇ Work rolls of finishing stands for hot strip mills
◇ Work rolls of finishing stands for hot bar mills
◇ Pre-finishing stands for high-speed wire mills
