Controlled Atmosphere Roller Mesh Belt Furnace Carburizing Furnace For Screws

What is Roller Type Mesh Belt Furnace?

Roller type mesh belt furnace is a fully automatic continuous heat treatment production line equipped with built-in high-temperature refractory rollers to support the alloy conveyor mesh belt inside the furnace chamber. Different from ordinary muffle mesh belt furnaces without rollers, the supporting rollers convert sliding friction between mesh belt and furnace bottom into rolling friction, effectively solving mesh belt sagging under heavy load & wide furnace width, greatly extending mesh belt service life, stable conveying and low operating cost.

The complete production line integrates automatic feeding, preheating, atmosphere heating, quenching tank, cleaning machine, tempering furnace and PLC central control system. It supports continuous mass production of small & medium metal parts for carburizing, carbonitriding, bright quenching, tempering, brazing and sintering under controlled protective atmosphere (nitrogen, methanol cracking gas).

Our roller mesh belt furnace adopts heavy-duty internal roller support structure, custom electric/gas heating modes, full closed protective atmosphere system and intelligent PLC automatic control. The whole line realizes unmanned continuous heat treatment for high-volume metal workpieces, widely applied in automotive fasteners, bearings, chains, hardware tools, bike spare parts and powder metallurgy industry.

Traditional non-roller mesh belts easily sag under heavy load, causing uneven heating, mesh belt abrasion and frequent replacement. Our built-in refractory roller array evenly bears mesh belt & workpiece weight, minimizing tension and friction loss, ideal for wide furnace (400–1200mm mesh width) and heavy-load mass production.

Roller Support, Ultra Long Mesh Belt Service Life

High-temperature self-lubricating refractory rollers reduce mesh belt tension & friction by 60%, no sagging even under full load; mesh belt replacement cycle extended 2–3 times vs standard mesh belt furnace, cut maintenance cost sharply.

Uniform Heating & Stable Product Quality

Multi-zone independent PID temperature control, temperature uniformity ±5℃ in constant temperature zone; oxygen probe real-time carbon potential monitoring, consistent hardness & surface brightness for every batch parts, low rejection rate.

High Energy Efficiency & Low Operation Cost

Composite aluminum silicate fiber insulation lining, waste heat recovery from return mesh belt to preheat cold workpieces; low-voltage radiation tube heating reduces power consumption, save 25–35% energy monthly.

Full Automatic Intelligent Control

Touch screen PLC system, adjustable mesh belt speed (20–170mm/min), one-click storage of multiple heat treatment process formulas; overload, belt deviation, over-temperature, gas shortage automatic alarm & interlock protection, less labor required.
