Core Points and Step-by-Step Guide for Installing Quenching Furnace Mesh Belts

The installation of quenching furnace mesh belts requires consideration of their structural characteristics and equipment requirements to ensure stability and safety. The following sections explain the differences in mesh belt types, installation procedures, and key considerations.

I. Types of Quenching Furnace Mesh Belts and Structural Compatibility

The most common mesh belt for quenching furnaces is the herringbone pattern stainless steel mesh belt. The edge treatment method directly impacts its performance after installation:

Direct Hemming:Effectively prevents material spillage and jamming, suitable for scenarios requiring high conveying stability.
Retaining Plates:Enhances edge wear resistance and reduces deformation risk, ideal for long-term high-temperature or heavy-load conditions.

II. Standard Installation Procedure for New Quenching Furnace Mesh Belts

1. Preparation
Tools & Materials:Prepare threading wire, welding equipment, chain connecting links (for chain-driven types), tape measure, etc.
Mesh Belt Inspection:Verify the edge treatment method (hemmed/retaining plates), wire diameter, and pitch conform to equipment specifications. For chain-driven types, check the compatibility between the chain and sprockets.

2. Core Installation Steps
Edge Joining,Align the edge wires of two mesh belt sections. Thread a connecting wire through and secure its ends by welding or crimping.
Disconnect the chain links. Align and re-engage the chain ends, ensuring even chain tension.
Equipment Fixation. Install the joined mesh belt onto the furnace support rollers. Adjust rollers to align the belt centerline with the equipment axis to prevent tracking issues.

3. Commissioning and Testing
No-Load Test Run:Start the equipment and observe mesh belt movement. Focus on checking for tracking issues or jamming. For chain-driven types, verify smooth engagement between the chain and sprockets.
Load Test:Feed a small amount of material. Verify the effectiveness of retaining plates/hemming in preventing leakage and the belt’s load-bearing capacity. After 30 minutes of operation, stop the machine and inspect weld joints or connecting links for looseness.

III. Installation Precautions and Long-Term Maintenance

Safety Protocols:Disconnect power and hang warning tags before installation. Wear heat-resistant gloves in high-temperature environments; avoid direct contact with the furnace body.
Thermal Expansion Allowance:Mesh belts elongate under high temperatures. Reserve adjustment space at the furnace ends. Trim excess length after 2 weeks to 1 month of operation.
Regular Inspection:Weekly – Check wear on edge retaining plates. Monthly – Tighten weld joints and chain connecting links to prevent material leakage or equipment damage caused by loosening.

IV. Troubleshooting Common Issues

Mesh Belt Tracking:Re-adjust support roller positions to ensure drive rollers rotate synchronously. Replace worn roller bearings if necessary.
Loose Connections:For welded belts, re-weld the threading wire joints. For chain types, replace worn connecting links and apply high-temperature lubricant to reduce friction.

Following these steps ensures the stable operation of a newly installed quenching furnace mesh belt, extends its service life, and reduces failure rates. In practice, adjust details flexibly based on the mesh belt type (woven/chain-driven), and refer to the equipment manufacturer’s installation manual when necessary.
