Brief introduction of structure:

(1) The car furnace is composed of a furnace body and a movable car

(2) The shell of the furnace body and the trolley are welded with high-quality steel plates and sections.

(3) The heating element adopts 0Cr27AL7Mo2 resistance belt produced by Shougang, which is arranged on the furnace door, furnace side, furnace back wall and platform car.

(4) The furnace lining is made of high aluminum fiber cotton, which has strong high temperature resistance and good thermal insulation, and is not replaced by ordinary fiber cotton. The load-bearing part is built with heavy firebrick to enhance the structural strength of the furnace lining. In order to ensure that the heat transfer at the bottom of the truck is not very high, the thermal insulation layer of the truck is composed of aluminum silicate refractory fiber and diatomite insulation brick to improve the thermal insulation performance of the furnace body.

Main technical features

The electric furnace is mainly composed of the furnace body (including the furnace door), the furnace lining, the furnace door lifting, the furnace car, the furnace car transmission mechanism, the electric heating device, the temperature control and recording system and other main parts.
