Equipment Overview
This roller-type mesh belt annealing furnace features a complete production line including a loading roller table, preheating section, multi-zone heating furnace, controlled cooling chamber, atmosphere-protection system, unloading rack, and PLC-based electrical control cabinet. The design guarantees uniform heating, precise temperature control (±1°C), and excellent temperature uniformity across both longitudinal and cross-section directions.
The furnace adopts a support roller structure, significantly reducing tension on the mesh belt and extending its service life. A high-purity ammonia-dissociated protective atmosphere ensures bright, oxidation-free annealing results — a key requirement for premium steel pipe manufacturing.
Main System Features
1. High-Efficiency Heating System
The furnace uses electric radiant tubes arranged above and below the mesh belt, powered through low-voltage dry-type transformers for safety and reliability. The multi-zone PID temperature control ensures stable and accurate heat treatment.
2. Robust Insulation Structure
The insulation structure is composed of anti-carburization bricks, ceramic fiber modules, and reinforced linings to minimize heat loss and maintain furnace stability.
3. Controlled Cooling Chamber
The cooling zone includes slow-cooling and water-cooling sections, reducing steel pipe temperature from ~500°C to below 150°C, ensuring metallurgical stability and preventing deformation.
4. Intelligent PLC Control
A Mitsubishi PLC with a 14-inch touchscreen provides full automation, data logging, alarm functions, speed control, temperature recording, and historical data export—ensuring stable, traceable production.
Conclusion
This Support Roller Mesh Belt Steel Pipe Annealing Furnace represents a high-performance, energy-efficient, and precision-driven solution for manufacturers seeking superior bright annealing quality for SAE 1008/1010 steel pipes. With optimized structure, stable protective atmosphere, and industry-leading automation, it delivers consistent production results while ensuring operational safety and long-term reliability. It is an excellent choice for heat-treatment workshops requiring advanced steel pipe annealing equipment, continuous bright annealing lines, and protective atmosphere furnaces.
