FAQ
Q: Why martensitic alloy grinding rolls for cement vertical mills?
A: Cement grinding brings heavy extrusion abrasion and cyclic thermal shock. Martensitic high chromium alloy balances ultra-high hardness and toughness, solving common issues of roller surface peeling, cracking and rapid wear.
Q: Can customize roller size and alloy formula for different grinding materials?
A: Yes, we adjust chromium, molybdenum and nickel content, roller wall thickness according to raw material hardness, mill output and service requirements.
Q: Can complete inspection certificates be provided before shipment?
A: Full test reports including hardness, metallographic, abrasion resistance and UT non-destructive inspection documents are available for project acceptance.
