The gas furnace is a national standard energy-saving type periodic operation furnace with ultra-energy-saving structure and energy-saving effect of 35%. The trolley adopts anti-impact sealing bricks, and the furnace door adopts a spring-type compression mechanism, which automatically seals the trolley and furnace door, and integrates the rails without foundation installation. It can be used on horizontal ground. Mainly used for high chromium, high manganese steel castings, nodular cast iron, rolls, steel balls, 45 steel, stainless steel and other quenching, annealing, aging and heat treatment of various mechanical parts.
Features of gas-fired trolley furnace:
1. Good energy saving effect: The furnace lining of the furnace body of this equipment is all made of high-alumina refractory fiber. Compared with refractory bricks, the thermal conductivity is small and the heat capacity is small, so the thickness of the refractory layer is small and the heat absorption is greatly reduced.
This equipment adopts a high-speed temperature-regulating burner system with a large spraying speed of 100m / s, which can effectively stir the furnace gas. The furnace temperature is uniform, and the burner system is completely burned, so that the fuel is fully utilized. Using furnace pressure zero control and full sealing technology, the maximum bonding surface (the sealing surface between the furnace car and the furnace body) is at zero furnace pressure. To use.
2. High degree of automation: The furnace door and furnace car are all electric and have an operation console. The operator can easily control the operation of the furnace door and furnace car. The furnace door and furnace car have stroke control, and can automatically stop running to the limit position to ensure safety.
The combustion system has a full set of ignition, high and low fire operation, detection, flameout alarm, flameout cut-off and re-ignition functions, and each set of burner has an independent control box, which can be controlled individually. Each control box interface can be connected with the temperature controller between the instruments, so that the entire system can be automatically controlled.
The pipeline parameters are controlled automatically. The pressure of the combustion air and fuel pipeline can be set and automatically adjusted, so that the amount of combustion air and fuel is controlled at the optimal ratio to ensure a high combustion efficiency and eliminate black smoke.
The furnace pressure is automatically controlled. The pressure signal of the furnace is compared with the set value through a pressure transmitter, and the signal is transmitted to the actuator of the chimney. The pressure in the furnace is automatically controlled by changing the opening of the chimney.
Furnace temperature control uses advanced intelligent digital display temperature controller, which consists of closed loop control with temperature measuring element and self-control burner. With high accuracy, high flexibility, anti-interference and high reliability. The temperature control system can automatically calculate, operate, display and store the heat treatment production process curve to realize the whole process control.
The instrument cabinet is equipped with temperature, furnace pressure, operating values of various burner nozzles, and various pipeline parameters, alarms and emergency protection measures to ensure safe operation.
