我厂定性炉炉膛尺寸为6200×2250×3020mm,燃烧煤气。炉门固定在台车上,这是比较广泛应用的形式。其特点之一,台车进出炉膛,省去了炉门的开和关,操作极为方便。该定性炉在长期使用中,发现炉门容易出现弯曲变形,整个炉门大平面向外倾斜,特别是炉门的上部和两侧部,钢板变形特别突出,这给工人操作,提高炉温和工件定性处理有一 I plant qualitative furnace hearth size of 6200 × 2250 × 3020mm, burning gas. Furnace door fixed on the trolley, which is more widely used form. One of its characteristics, trolley out of the furnace, eliminating the need to open and close the door, the operation is extremely convenient. The long-term use of the qualitative furnace found that the furnace door is prone to bending deformation, the entire furnace door large flat outward tilt, especially the upper part of the door and the two sides of the Ministry, particularly deformed steel plate, which gives workers the operation to improve the temperature and workpiece qualitative Deal with one
