Tuyere slag line zone: very harsh working conditions, always being eroded by molten blister copper penetration, copper slag (is mainly SiO2-FeO-CaO)chemical reaction damage, matte SO2 gas proliferation erosion and oxygen spray process oxidation-reduction reaction damage, high temperature hydration, refining process over heat reaction damage and spraying process temperature severe change and over heat liquid rigorous erosion, mechanical fatigue due to periodic operations. Only high Chrome DMK and RMK products endure such vigorous damages.
Working lining: due to periodic rotating operations copper slag, matte, SO2 gas proliferations etc. chemical erosions, penetrations, temperature changes etc. damages, all these erosions and damages are only less rigorous to the working linings, therefore medium grade Chrome DMK, RMK and KPA products are recommended.
