Composite cemented carbide roll rings

KOCKS cemented carbide roll rings

KOCKS Cemented Carbide Roll Rings for KOCKS three-roll mil to replace the original bllmilling of cast iron roll ring,mainly the production of bearing steel, spring steel, alloy steel and other special steel, steel surface and tolerance con-trols are clearly better than cast iron roll ring and wear-resistant is good, life is a cast iron roll ring 10 times.

Three dimensional carbide rolls tor cold rolling ot ribbed steel bars

The steel reinforcement rlled by three dimensional carbide rolls has fine appearance surfacehigh precision in dimension andclear ribbed mark. Thoseimproved the comprehensive properties Of rbbed steel reinforcements. The primary rllingtonnageare 600 -2000tons. which is 20- -30 times more than that of common tool steelrolls. Because cemented carbide rolls can bereground and used again. the production cost is reduced greatly. That markedly improved productive fficiencyand profit.
