Metal chain plates, stainless steel chain plates, drive chain plates

Metal chain plates are conveyor components made from metals such as stainless steel and carbon steel. Thanks to their high load-bearing capacity, wear resistance, and heat resistance, they are widely used in various industrial production lines.

🛠️ Main Applications

They are primarily used in the following scenarios:

· Heavy-duty materials and processing: Conveyors for iron chips, stamping scrap, and various castings; particularly suitable for conveying chips containing coolant.
· High-Temperature and Harsh Environments: Used in heat treatment furnaces, dryers, and tunnel kilns, or in heavy-duty environments such as mining and metallurgy.
· Food and Fine Chemicals: Conveys vegetables, frozen foods, canned goods, and pharmaceuticals; the surface can be perforated to facilitate drainage.
· Automated Assembly Lines: Used for conveying and packaging in industries such as motorcycle assembly, automotive parts, and tobacco.

✅ Key Advantages

Compared to other conveying methods, its advantages include:

· High Load Capacity and Durability: High load capacity, capable of withstanding high-intensity impacts, and long service life.
· Heat and Corrosion Resistance: Stainless steel construction withstands high-temperature baking and humid, corrosive environments.
· Smooth Operation: Flat surface ensures stable operation, enabling horizontal, inclined, or curved conveying.
· Easy Maintenance: The structural design facilitates installation and makes cleaning and maintenance straightforward.

⚠️ Precautions for Use

· Higher Cost: The cost is typically higher than that of engineering plastic chain conveyors.
· Operating Guidelines: It is recommended to start the system under no-load conditions, with speeds generally not exceeding 2.5 m/s, and to avoid contact with heat sources.
· Misalignment Correction: If misalignment occurs, adjust the tensioning shaft and check whether the sprockets at both ends are synchronized.

The key factors in selecting metal chain plates are pitch, plate thickness, and material. The specific specifications are as follows:

1. Core Dimensional Parameters

· Pitch: Refers to the distance between the centers of two adjacent chain plate pins, which determines the conveying accuracy and load-bearing capacity.
· Light/Medium Duty: 25.4 mm, 31.75 mm, 38.1 mm (suitable for food and light industry)
· Heavy-duty: 50.8 mm, 63.5 mm, 76.2 mm (suitable for stamping and mining)
· Extra-heavy-duty: 101.6 mm and above
· Plate Thickness: Directly affects load-bearing capacity and service life.
· Common range: 1.0 mm – 4.0 mm
· Recommendations: Choose 1.0–1.5 mm for light-duty applications; choose 2.5 mm or above for heavy-duty applications.
· Chain plate width: Primarily custom-made. Single-row chains typically start at 63 mm; actual production dimensions are determined based on customer requirements.

2. Materials and Performance

· Stainless steel: 304 (food/heat-resistant) or 316 (strong acids and alkalis) are recommended. SUS420 is commonly used for wear-resistant straight-run chains.
· Carbon Steel: Ordinary steel or 45Mn steel. Low cost and extremely high strength, but must undergo anti-corrosion treatment.
· Performance Specifications: The larger the pitch, the greater the tensile strength (e.g., a 101.6mm pitch can achieve a maximum tensile strength of 226.8 kN). Recommended speed should be kept below 2.5 m/s, and the turning radius is typically required to be ≥ 150mm.

3. Structural Details and Customization

· Flat Plate: Standard flat surface, suitable for smooth conveying.
· Perforated Plate: Features round or slotted holes for oil drainage, water drainage, or ventilation.
· Side Guards: Installed on both sides or across the width to prevent material from sliding off, suitable for steep inclines.

4. Quick Selection Guide

Heavy-duty chip removal/stamping applications (heavy scrap, oily conditions): Select a pitch of 50.8 mm or greater + 2.5 mm plate thickness + carbon steel (cost-effective) or 304 stainless steel (corrosion-resistant).

High-temperature drying/food processing applications (heat resistance, drainage): Select 38.1 mm pitch + 1.5 mm thick perforated plate + 304 stainless steel.
