Cart quenching furnace is a cycle operation type resistance furnace, mainly for die steel, hardware mold, casting parts, forging parts and other metal quenching, annealing, normalizing treatment can also be used as a sintering furnace. Used for high chromium, high manganese steel castings, ductile iron, rolls, steel balls, 45 steel, stainless steel and other quenching, annealing, aging and heat treatment of various mechanical parts.

Characteristics of cart quenching furnace

Shell by the steel plate and steel welded together, the bottom of the furnace body and the cart light rail connected as one, the user does not need to install the foundation, only to be placed on the level cement floor can be used, the furnace lining material using ultra-lightweight 0.6g/cm3 energy-saving refractory heat preservation bricks masonry, the sandwich placed in the aluminosilicate fiber felt heat preservation, the furnace shell and the furnace lining silica-aluminum brazing sandwich filled with expansion to the rock dust heat preservation, the furnace mouth using heavy anti-collision bricks, the surface of the trolley Heavy high alumina anti-pressure bricks. The electric furnace body and the cart between the labyrinth refractory masonry, but also through the self-acting sealing mechanism to reduce the heat radiation and convection loss of the electric furnace, and can improve the furnace temperature uniformity. This electric furnace heating element are spiral heat generator, resting on the side of the furnace shelving wire brick and cart masonry, heating element material for the international general 0Cr25AL5, element maximum operating temperature of 1200 ℃.

Trolley installed with chromium-manganese nitrogen heat-resistant steel furnace floor or 1200 ℃ silicon carbide furnace floor in order to carry the workpiece, in order to prevent the workpiece heated to produce oxidized skin through the furnace floor gap falls into the bottom of the heating element around the heating element damage, the need for frequent and regular blowing of the cart furnace floor below the oxidized skin, generally weekly blowing a blowing, blowing the bottom of the furnace analysis of the lifting, the compressed air will be the resistor wire slot in the Oxidized skin debris blowing clean.

The lift of the door of the trolley furnace is through the rolling wheel on the guide rail, rolling up and down to achieve, so as to ensure the closure of the door when the door masonry and furnace masonry between the anastomosis seal, but also to ensure that in the process of opening the masonry will not be friction damage, the door of the furnace and the movement of the cart are by the motor through the worm gear reducer deceleration, the chain drive to provide, and equipped with an electromagnetic brake to make the appropriate adjustments. In order to improve the furnace temperature uniformity, the furnace adopts multi-zone heating and arranges heating elements on the door and back wall for future maintenance and replacement.
