Product Details

Description：

Engineered to combat severe abrasion from sand and gravel during concrete mixing, our high-chromium cast iron liners address the critical challenge of balancing hardness and structural stability in thin-walled designs.

Unlike conventional liners that deform under heat treatment at high area-to-thickness ratios, our 20mm-thick plates utilize a proprietary alloy formula (Cr 23-26%, Mo 1.5-2.2%) and controlled quenching processes to achieve HRC58-62 hardness without compromising flatness (±0.8mm tolerance).

The reinforced trapezoidal rib design on diamond/trapezoid arc liners enhances load distribution, preventing warping even under prolonged high-impact mixing cycles. Produced via vacuum-sealed lost foam casting, these liners maintain dimensional precision while eliminating stress concentration points common in sand-cast alternatives.

Features and Advantages

Multi-Position Protection: Includes right/left/center end liners, diamond arc liners, and trapezoid arc liners for full drum coverage.

High-Chromium Cast Iron: HRC58-62 hardness ensures exceptional resistance to sand, gravel, and concrete abrasion.

Optimized Design: 20mm thickness balances impact absorption and structural integrity.

Precision Manufacturing: Produced via lost foam casting (±0.5mm tolerance) and vertical flaskless molding lines for consistent quality.

Material Purity: Melted in medium-frequency induction furnaces for uniform alloy composition.

Extended Lifespan: 30% longer service life compared to standard liners, reducing replacement frequency.

OEM-Compatible Fit: Engineered to match JS2000 mixer drum dimensions for seamless installation.

Cost Efficiency: Minimizes downtime and maintenance costs with robust wear protection.

Certified Quality: ISO 9001-certified production ensures reliability and traceability.

Production Line Capabilities

1、Vertical Flaskless Molding Line: Enables high-speed, large-batch production with minimal dimensional variance.

2、Lost Foam Casting: Delivers complex geometries and smooth surfaces for precise fitment.

3、Medium-Frequency Induction Furnace: Ensures uniform melting of high-chromium alloys (Cr content 15-28%).
