LBR-4020 Asphalt Mixer Liner - High-Toughness Thermal Fatigue Resistant Plate

Engineered for the LBR-4020 series asphalt batching plants, this high-toughness liner is specifically designed to combat thermal fatigue and extreme impact forces in continuous hot mix production. Manufactured under ISO 9001-certified processes, each liner is precision-cast using advanced lost-foam casting (EPC) and vertical flaskless molding technology, achieving a material density of 99.8% to eliminate micro-porosity and ensure structural homogeneity. This level of purity, achieved through medium-frequency induction furnace refining, directly translates to enhanced thermal stability, reducing crack initiation under repeated temperature cycles from 20°C to 200°C.

The liner's core composition is a proprietary high-chromium alloy (27-31% Cr) fortified with molybdenum and nickel, creating a refined metallographic structure of M7C3 carbides in an austenitic matrix. This structure delivers a balanced hardness of 56-62 HRC while providing exceptional impact toughness (≥8.2 J/cm²) and a tensile strength of 475 N/mm². Independent tests verify that these liners withstand over 320,000 tons of asphalt mixing—focusing on superior resistance to thermal cycling—which extends service life by 50% compared to standard liners. The flexural strength exceeds 620 N/mm², ensuring dimensional integrity under heavy mechanical loads.

Our digital energy management system optimizes the liner's geometry through finite element analysis (FEA), reducing stress concentrations at high-temperature points by 45% and minimizing energy consumption. Each liner is CNC-machined to ±0.15mm tolerance for perfect LBR-4020 compatibility, enabling seamless installation. Backed by 40+ years of technical expertise, we provide lifecycle support, including digital wear analytics, to help asphalt plants reduce downtime and lower operating costs by extending maintenance intervals.

• • Advanced Composite Structure: The high-chromium alloy (28-32% Cr) with molybdenum and vanadium additives ensures a hardness of 58-64 HRC, offering a balanced resistance to both severe abrasion and impact forces in asphalt mixing.

  • Precision Casting Technology: Our lost-foam casting (EPC) and vertical flaskless molding lines achieve a material density of 99.8%, eliminating defects and guaranteeing structural integrity for a longer operational lifespan.
  • Proven Extended Service Life: Independently verified to handle over 300,000 tons of asphalt mixing, providing up to a 50% longer service life compared to standard liners, which reduces replacement frequency and downtime.

 

• • Optimized Thermal Stability: The refined metallographic structure maintains dimensional stability and mechanical properties under continuous high-temperature operation, resisting deformation and thermal fatigue.

  • Anti-Adhesion Surface Design: The proprietary wave-pattern surface effectively reduces asphalt material buildup by over 60%, ensuring consistent mixing efficiency and reducing cleaning effort.

  • Comprehensive Quality Assurance: Manufactured under ISO 9001 certified processes with complete material traceability, supported by technical data sheets and after-sales service.
