HISAN High Chromium Wear Resistant Coal Chute features a curved streamline design that completely eliminates coal blockages, dust emission and heavy impact. Made of high-chromium wear-resistant material with chromium content over 35% and hardness above HRC 60, it delivers greatly enhanced durability. HISAN curved coal chutes offer a service life of more than 5 years, significantly cutting costs and boosting efficiency to put an end to frequent pipe replacements.
Custom-engineered Hisan high-temp surfacing wear pipes adopt 310S heat-resistant stainless steel base tubes, with auto-surfaced Cr-Mo-Nb-W-V multi-alloy inner liners metallurgically bonded to substrates. Free of high-temp spalling & cracking, it solves chronic failures including ceramic liner falling off and bimetal casting thermal cracks.
Field test at a coal preparation plant: HS‑F Smooth Surface CCO Wear Plates in 6+4 mm specification, with a 4 mm hardfacing layer hardened to HRC58‑62. Its seamless smooth surface prevents coal slime sticking efficiently, stabilizes homogenizing performance, cuts downtime for maintenance and part replacement, lowers operational expenses, and addresses the dual issues of impeller wear and material adhesion.
