Overview

The SHINING P85-3L Heightened Plate Steel Mill Chain is a heavy-duty engineered roller chain exclusively designed for the rigorous material handling demands of steel mill hot rolling production lines. Featuring a rugged alloy steel construction with a 85mm pitch and precision-integrated heightened inner/outer plates (installed at a fixed interval of every 3 links), this chain is engineered to deliver uncompromising stability, anti-slip positioning, and wear resistance for the directional conveyance of hot-rolled billets, bars, and small-section profiles. Boasting a guaranteed average tensile strength of 100kN and ultra-precise dimensional control, it ensures reliable, jam-free operation in the high-temperature, high-wear industrial environments of steel manufacturing, serving as a critical component for seamless hot rolling line material flow.

Features

1. Precision Heightened Plate Design

The signature dual-sided heightened inner/outer plates (Type A/B) form a protective anti-roll barrier, preventing the offset and falling of hot-rolled workpieces during conveyance—an essential design for the accurate directional transport of steel billets and profiles to the cooling bed and laminar cooling line. All plate edges feature rounded corner finishing (R2/R3/R5/R15) for structural integrity and to avoid workpiece scratching.

2. High-Strength Alloy Steel Construction

Core components including sidebars, heightened plates, and pins are manufactured from premium alloy steel, with precision heat treatment delivering tailored hardness ratings. This achieves the perfect balance of structural toughness for heavy loads and surface wear resistance for prolonged service life in abrasive steel mill conditions.

3. Superior Operational Performance

Stringent manufacturing tolerances control chain length accuracy within +0.25/0%, and precision-machined hinges ensure smooth, flexible rotation with zero jamming—critical for continuous, uninterrupted operation in high-throughput steel mill production lines. Integrated inner/outer link cushion blocks absorb impact from workpiece loading, reducing component deformation and extending chain lifespan.

4. Optimized Heat & Corrosion Protection

Carburizing and high-frequency quenching treatments on wear-critical components (roller, bush, pin) create a hard, dense surface layer that resists high-temperature oxidation and wear from hot steel workpieces (400-800℃). The complete chain is thoroughly cleaned, oiled, and corrosion-protected for reliable storage and operation in dusty, humid steel mill workshops.

5. Easy Installation & Maintenance

Pre-assembled with high-strength 10.9 grade M8 countersunk hex screws and SS304 stainless steel cotter pins/flat washers, the chain features a bolted connection design for the heightened plates—enabling quick on-site disassembly, replacement, and maintenance. Standardized interface dimensions ensure seamless integration with existing steel mill conveyor systems and sprockets.

Primary Applications

This chain is a purpose-built solution for material handling in steel mill hot rolling production lines, where stable, anti-slip conveyance of hot workpieces is paramount:

• Hot Rolling Laminar Cooling Line: Ideal for the directional conveyance of hot-rolled bars, profiles, and small square billets to cooling stations, preventing workpiece offset during the cooling process.

• Cooling Bed Infeed Conveyance: Precisely positions hot-rolled workpieces for smooth transfer to the cooling bed, ensuring uniform cooling and reducing production defects.

• Hot Rolling Mill Exit Transition Conveyance: Serves as the critical transfer chain between the rolling mill and subsequent processing equipment, maintaining continuous material flow in the hot rolling line.

• Steel Mill Medium-Sized Billet Conveyance: Suitable for the transport of small-to-medium square/rectangular billets (non-heavy slab) in the hot rolling workshop, with the heightened plate design adapting to various billet specifications.

Why SHINING P85-3L for Steel Mill Hot Rolling?

While standard conveyor chains offer basic material handling capabilities, the SHINING P85-3L is the superior choice for steel mill hot rolling lines due to its application-specific engineering:

• Workpiece-Specific Anti-Roll Design: The every-3-links heightened plate configuration is tailored to the dimensions and weight of hot-rolled steel workpieces, eliminating the common issue of workpiece falling/offset in standard chain conveyance.

• Temperature-Resistant Material Engineering: Heat treatment and alloy steel selection are optimized for the 400-800℃ operating temperature of hot rolling lines, avoiding premature failure from high-temperature softening or oxidation— a limitation of generic industrial chains.

• Mill-Ready Robustness: Built to withstand the heavy loads, dust, and mechanical impact of steel mill operations, with cushion blocks and reinforced connections that address the unique abrasive and shock loads of hot steel conveyance.

• Precision for High Throughput: Tight dimensional accuracy and jam-free operation ensure alignment with the high-speed, continuous production demands of modern steel mills, reducing unplanned downtime and improving production efficiency.
