With the continuous improvement of industry requirements for production efficiency, energy conservation and consumption reduction, traditional liner materials can no longer meet the high-intensity operation needs under complex working conditions. Against this background, pearlitic chromium-molybdenum steel liners, relying on their unique material advantages and excellent service performance, have become the preferred solution for many enterprises to upgrade grinding equipment. They can even increase ore grinding efficiency by 20%, empowering and improving production efficiency. Material Composition and Manufacturing Process Pearlitic chromium-molybdenum steel liners are made of high-quality pearlitic chromium-molybdenum alloy steel, with common material grades including ZG35CrMo, ZG42CrMo and other customized alloy grades. They are manufactured through precision casting, CNC machining and strict quenching + tempering heat treatment processes. Their core composition ratio is scientific, with a carbon content between 0.30% and 0.45%, matched with 0.8% to 1.5% chromium element and 0.2% to 0.6% molybdenum element, supplemented by trace elements such as silicon and manganese. This forms a special structure with fine pearlite as the matrix and dispersed chromium carbide hard phases, which is the key to its combination of high strength, high wear resistance and excellent toughness. Outstanding Performance Advantages Superior Wear Resistance: The fine pearlite matrix ensures high hardness (HRC 45-55) and structural compactness, with embedded chromium carbide hard phases further enhancing wear resistance. The service life is 2-3 times longer than that of ordinary carbon steel liners, significantly reducing replacement frequency and maintenance costs. Excellent Impact Toughness: While having high hardness, it maintains excellent impact toughness (impact energy ≥35J/cm²), capable of resisting the impact of 5-10kg large ore lumps, effectively preventing cracking and spalling, and ensuring stable operation. Good High-Temperature Stability: The addition of molybdenum elements refines the grain structure, allowing stable mechanical properties in high-temperature environments of 300-500℃, ideal for cement clinker grinding. Excellent Welding Performance: The pearlite matrix allows for repair by surfacing welding when partially damaged, significantly reducing equipment downtime and replacement costs, and improving comprehensive utilization efficiency. Diverse Application Scenarios Relying on their dual advantages of "wear resistance + impact resistance", pearlitic chromium-molybdenum steel liners are widely used in the medium and coarse grinding stages of ball mills and semi-autogenous mills in the mining industry.
