It is mainly used for high temperature baking of mold shells after dewaxing. The equipment is a trolley-type structure. The mold shells to be fired are placed on the trolley. The furnace lining is a composite structure (heavy acid-resistant high alumina bricks and aluminum silicate fiber cotton). The side of the furnace is equipped with a special burner for gas, and the flue gas is discharged from the plant through the flue exhaust port at the tail of the furnace body. The flue is provided with a waste heat recovery device for preheating combustion air. Trolleys come in and out automatically on the rails. The equipment has a high degree of automation, low energy consumption, reliable operation and stable product quality.
Trolley-type mold case roasting furnace is mainly composed of furnace body (including furnace lining), furnace door and lifting mechanism, trolley and walking mechanism, sealing device, combustion system, various pipelines and pressure automatic control system, automatic control of furnace pressure and exhaust waste heat recovery System, temperature control and recording system
