This furnace is consisted of several parts, manufactured in the factory, assembled at worksite, conveniently and quickly.
(1). Heated by direct fire and controlled by oxygen-deficient and oxygen-overmuch combustion.
(2). To adopt countercurrent type furnace, namely steel moving direction is reverse with fire moving direction, flue is discharged from upper feeding inlet. Between furnace outlet and lead boiler, there place sealing device and novel atmosphere protection, to reduce steel oxidation efficiently.
(3). 2-4 PCS hot wind gas fired nozzles are uniformly distributed at furnace top. Nozzle combustion is totally enclosed, combustion is stable, adjustment ratio is bigger. Suitable for hot air producing.
(4). Exactly controlling furnace temperature and inner atmosphere, to carry out high DV value operation.
(5). Setting wire moving slot at furnace inlet, it is easily to achieve steel moving and steel carrying.
(6). To use high efficiency energy saved waste heat recycling device.
(7). Perfect and reasonable protector may ensure the furnace working safely. When power or gas is cut-off abruptly, quickly shut off valve on gas general pipe will close immediately, sound and light will be given as an alarm from computer control system. Purpose-made safe explosion-proof valve is fixed at every gas branch pipe to avoid all the unexpected accidents.
