DOOR STRUCTURE IN HEATING FURNACE

摘要

PURPOSE: A door structure of a heating furnace is provided to prevent the excessive inflow of exterior air by coping with the skew of carried semi-products. CONSTITUTION: A door structure of a heating furnace comprises a furnace body(10) and a plurality of blocking panels(110,120). The furnace body has an entrance and an exit on both sides through which semi-products are loaded and discharged, and is provided with a door(20) which opens and closes the entrance and the exit. The blocking panels are arranged on the rims of the entrance and the exit and coupled to the entrance and the exit with connecting units. The blocking panels are rotated upon contact with semi-products and then restored to the original position.
