8m gas trolley furnace product introduction
The gas furnace is a national standard energy-saving type periodic operation furnace with an ultra-energy-saving structure and an energy-saving effect of 35%. The trolley adopts anti-impact sealing brick, the furnace door adopts a spring-type compression mechanism, the trolley and furnace door are automatically sealed, and the integrated rail is integrated. It can be used on a level ground without foundation installation. 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 nozzle system, with a large ejection speed of 100m / s, which can effectively stir the furnace gas. The furnace temperature is uniform, and the nozzle system burns completely, so that the fuel is fully utilized. The furnace pressure zero control and full-sealing technology are adopted. The maximum bonding surface (the sealing surface between the furnace car and the furnace body) is at zero furnace pressure. The furnace gas is not leaked and the cold air is not infiltrated, so that the heat generated by the combustion can be effectively used. To use.

2. High degree of automation: The furnace door and the furnace car are all electric and have an operation console. The operator can easily control the operation of the furnace door and the furnace car. 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, large and small 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.
