Advantages and disadvantages of bright annealing furnace and improvement measures
The bright annealing furnace is a medium industrial furnace with long strip shape. The continuous bright annealing furnace of axle in forging and metallurgy workshop of vehicle factory originally used fuel oil sub high speed burner, which is mainly used for heat treatment of train axle after heating and casting. It is one of the most important equipment in forging and metallurgy workshop of vehicle factory.
The furnace temperature of the reformed bright annealing furnace is divided into three zones, in which the workpieces are pushed into the furnace zone I - heating zone by pusher. There are four burners staggered under the walls on both sides. The track is supported by an arch made of refractory bricks, so that the workpieces can be heated on both sides. Then there are zone II and zone III - constant temperature zone, and four burners staggered at the same height of the walls on both sides. The eight burners are all low-pressure vortex burners, with space beams between zone 1 and zone 2, and two composite metal heat exchangers at the front and back of the furnace.
Both sides of the furnace wall and furnace bottom are made of brick structure, the furnace top is made of refractory fiber felt, and a high-pressure fan is selected to supply combustion air and exhaust air. There are control valves and flow orifices on the gas and air main pipes, as well as control valves on the injection air main pipes. They are equipped with a set of leading microcomputer control system, display instrument and protection equipment.
