Continuous Mesh Belt Bright Annealing Furnace, Oxidation-Free Heat Treatment for Stainless Steel Cop

The Continuous Mesh Belt Bright Annealing Furnace is a fully automatic, tunnel-type continuous heat treatment equipment designed for large-volume metal annealing production. Adopting sealed protective atmosphere system (ammonia decomposed gas, pure nitrogen or hydrogen mixed gas), the furnace realizes oxygen-isolated heating, soaking and cooling process. It effectively eliminates metal internal stress, refines grain structure, and delivers mirror-bright workpiece surface without oxidation, decarburization, blackening or scaling. Widely applied in continuous annealing and stress relief of stainless steel, copper alloy, carbon steel and precision hardware parts, it is the core equipment for standardized and automated metal heat treatment production lines.

1.Zero Oxidation, Mirror-Bright Finish Strictly sealed furnace body, internal oxygen content controlled below 10ppm. Whole-process protective atmosphere isolation ensures no surface oxidation or discoloration. Workpieces maintain original metallic luster, completely save pickling, grinding and polishing processes, lower production costs and meet environmental standards.

2.24H Uninterrupted Mass Production Stable mesh belt continuous conveying design, no batch interval downtime. Realizes fully automated feeding, heating, cooling and discharging. Suitable for long-term continuous mass production of small and medium-sized workpieces, greatly improving production efficiency.

3.Precise Multi-Zone PID Temperature Control Multi-section independent PID intelligent temperature control system, temperature control accuracy ±1℃, furnace temperature uniformity ≤±5℃. Consistent heating effect ensures uniform metal hardness and ductility, avoiding cracking and deformation in subsequent stamping and bending processes.

4.Energy-Saving & Low Operating Cost Full aluminum silicate fiber heat insulation lining, low heat loss and good thermal insulation performance. Optimized heating structure and waste heat recovery design reduce power consumption by 25%-40% compared with traditional furnaces. Frequency conversion speed regulation system saves more energy and adapts to different production speeds.

5.High Stability & Long Service Life Key components adopt thickened 310S high-temperature stainless steel muffle and imported high-temperature resistant mesh belt, anti-deformation and anti-oxidation. Heating elements are externally arranged for quick replacement and easy daily maintenance, equipment operation rate over 98%.

6.Intelligent Safety Interlock System Equipped with over-temperature alarm, gas pressure protection, water shortage protection and air leakage automatic interlock shutdown function. PLC touch screen one-key operation, real-time monitoring of furnace temperature, gas flow and pressure, safe and labor-saving.

The continuous mesh belt annealing furnace adopts tunnel-type integrated structure. Workpieces are evenly conveyed into the furnace by a high-temperature resistant mesh belt. Under the sealed oxygen-free environment filled with protective gas, workpieces are gradually preheated, heated and insulated to complete metal recrystallization and stress relief. After uniform and controllable water cooling in the sealed cooling zone, workpieces are discharged with mirror-bright surface, realizing continuous and standardized bright annealing processing.
