Engineered for extreme abrasion resistance in LBQ2000 asphalt mixing systems, Zhongrun's G/H-Type Liners leverage advanced metallurgical solutions to redefine operational longevity. Manufactured under ISO 9001-certified processes, these liners undergo precision lost foam casting (EPC) and vertical flaskless molding to achieve 99.2% material density – eliminating porosity defects that cause premature wear. Our proprietary high-chromium alloy (24-32% Cr content) is smelted in medium-frequency induction furnaces, enabling exact control over carbide distribution for uniform hardness (58-62 HRC). This metallurgical optimization results in 30% longer service life than industry averages, directly reducing downtime and replacement costs for batch plants. Digital energy-saving management is integrated throughout production, from CAD-simulated wear patterns to heat treatment optimization, ensuring each liner matches LBQ2000 mixer kinematics. Supported by our technical team with 20 years of mixing equipment expertise, we provide installation guidance and wear analysis reports. Customizable bolt-hole configurations and curvature tolerances (±0.5mm) guarantee seamless retrofitting. Choose liners that transform maintenance cycles from cost centers to competitive advantages.
Material Excellence: High-chromium cast iron with 28% Cr content for extreme abrasion resistance.
Heat Treatment Advantage: Proprietary quenching process eliminates deformation, enhancing hardness uniformity.
Quality Assurance: ISO 9001-certified production with spectrometric composition control.
Precision Geometry - precision mounting surfaces with ±0.4mm tolerance for LBQ2000 compatibility
Carbon-Neutral Production: Regenerative thermal oxidizers capture 95% of foundry emissions.
