Function:
Matched with gears, it realizes precise linear transmission under heavy‑load conditions and endures long‑term service under harsh steel‑mill operating environments.
Features:
High strength, high‑temperature resistance, impact resistance, wear resistance and stable precision. Its surface is generally treated by quenching or carburizing.
Main Features:
The hardness of steel‑mill‑special racks normally reaches HRC35‑50, with surface roughness controlled below Ra1.6 to guarantee wear resistance and smooth transmission. Our actual test data shows that the wear loss of high‑quality racks in steel mill environments is only 1/2‑1/3 of that of ordinary racks.
Impact resistance is another key indicator. By optimizing material composition and heat‑treatment processes, the rack can withstand instantaneous impact loads 2‑3 times higher than those of ordinary racks. Some high‑end products also adopt special coating technologies such as molybdenum disulfide coating to further reduce the friction coefficient.
