The gas-fired roller annealing furnace is mainly used for heat treatment of alloy pipe, copper pipe, steel pipe, stainless steel pipe, straight pipe and mosquito coil under protective atmosphere.

The gas-fired roller annealing furnace consists of feeding frame, heating furnace body, combustion system, transmission system, smoke exhaust system, cooling water tank, discharging frame, control system, etc.

The combustion system consists of several high-speed burners, which are evenly distributed on both sides along the longitudinal direction of the heating furnace. Continuous proportional control combustion. The air volume is adjusted by the actuator, and the gas volume is adjusted by the proportional valve to achieve the air-fuel proportional combustion. The gas and air volume are set with the lower limit. The gas pipe of each burner is equipped with the control solenoid valve. Each burner is equipped with an independent and complete combustion controller, which has the functions of automatic ignition, flame detection, fire alarm and automatic gas cut-off. This fully ensures the stability and safety of the combustion temperature control system.
