4．炉门及升降密封装置4.1 因电炉炉门较大，炉门外框架采用10#槽钢

4. Furnace door and lifting sealing device <br>4.1 Due to the large electric furnace door, the outer frame of the furnace door is made of 10# channel steel, and the side plate is welded and formed by 10mm thick Q235 steel plate, which enhances the strength of the mechanism and is not easy to deform and warp. <br>4.2 The lining of the furnace door is also a full-fiber structure. <br>4.3 The lifting of the furnace door uses a 2t electric hoist as the lifting power of the furnace door, and is equipped with a braking device to make the furnace door rise and fall smoothly. <br>4.4 The furnace door is sealed with a self-weight spring compression device, which makes the furnace door and the furnace panel softly contact and sealed. This structure enhances the sealing strength at the furnace mouth and reduces heat loss.
