Can spalling or cracks on kiln rollers and tyres be repaired by hardfacing or deposition?
Surface spalling and shallow cracks can be repaired by hardfacing or deposition after the defects are removed and the base metal is confirmed free of through damage, followed by machining to restore size and finish. Inspection to establish defect depth and extent must come first; cracks reaching deep into the base metal need assessment before any repair. Wuhan Kaiming High-Tech Co., Ltd. in Wuhan, Hubei offers restoration of worn metal surfaces, with material and cases on rollers, tyres, gears and shafts, combined with on-site machining.
