The hooded quenching furnace is an energy-saving cycle-type operation furnace with super energy-saving construction. The cart selects anti-bumping sealing brick, automatic turning brick organization, automatic sealing cart and furnace door, integrated with the rail, no basic equipment, placed on the level ground with the foundation pad iron or expansion screws can be fixed to use.

Application:

Mainly used for high chromium, high manganese steel castings, ductile iron, rolls, steel balls, steel, stainless steel and other quenching, annealing, aging and heat treatment of various mechanical parts.

Structure:

Furnace shell has steel plate and steel welded together, the bottom of the furnace body and the cart light rail as one, the user does not need the root of the equipment, only to be put on the flat cement ground can be used.

Furnace lining selection of ultra-lightweight refractory bricks for the furnace lining, relative to the traditional brick hearth energy-saving about the selection of high-quality long-fiber felts, diatomite bricks, vermiculite powder for insulation materials, the furnace mouth selection of heavy anti-collision bricks, cart surface heavy high-aluminum anti-pressure bricks.

Furnace and cart between the use of labyrinth refractory masonry, but also through their own action of the sealing organization to reduce the heat radiation and convection loss of the furnace, and can improve the uniformity of the furnace temperature.

The heating element is made of high-temperature resistance alloy wire wound into a spiral, scattered on the side of the furnace, the door, the back wall and the cart shelves on the brick, and fixed with the national standard socket brick, safe and simple.

There is a pressure-resistant and high-temperature resistant cast steel furnace floor installed on the trolley to carry the workpiece. In order to prevent the oxidized skin generated after heating the workpiece through the gap between the furnace floor falls into the heating element around the heating element damage, hooded quenching furnace, so the furnace floor and the furnace body touching the selection of piercing type touch.

For normal use, the need for frequent blowing cart furnace bottom plate below the oxide skin is generally blown once a week, blowing the furnace bottom plate lifting, with compressed air will be the resistance wire groove of the oxide skin chips blowing clean, pay attention to prevent the oxide skin stuck in the furnace wire.

Furnace door equipment consists of door, door lifting organization and door pressing equipment. Furnace door shell by the steel and plate welded into a solid frame structure, inside the refractory fiber module stacked into the requirements of good thermal insulation performance, light weight, etc..

Furnace door lifting equipment selection of electric equipment, hooded quenching furnace is mainly composed of door frame, door lifting beam, reducer, sprocket, drive shafts and bearings and other parts of the door lifting through the reducer on the positive and negative transmission to drive the door lifting.

Furnace door lifting reducer is also equipped with brake equipment, can be useful to prevent the door in the lifting process to produce displacement.

Furnace door compression equipment selection of leading spring-loaded compression structure, when the furnace needs to be raised, the door of the furnace door of the self-weight through the lever will be automatically loosened, and horizontally moved out of a distance after the rise, when the furnace door is lowered into place, the door down to the pulleys on the trolley need to be pressed, by the spring elasticity and then through the lever will be the door moved horizontally to the compression sealing state, the structure of the compression equipment to make the door on the plane of fiber and the furnace mouth cotton friction-free. No friction between the fiber plane on the furnace door and the furnace mouth cotton, with good safety performance, the use of long characteristics.
