退火炉窑的密封性,对铸件的退火质量有直接影响,对节约能源起重要作用。我厂原退火炉台车尾部的密封,采用砖堵泥封法,即将台车放好后根据台车边沿与砌体之间的距离大小用砖堵死,砖外边糊一层泥巴,这种方法既浪费人力、物力,密封性也差。当炉内升到一定温度时,外封泥皮龟裂,黑烟从上边砖缝向外溢,冷空气从下边砖缝进入炉内,造成靠近炉门的铸件退火质量达不到要求,还需进行二
Annealing furnace sealing, the quality of the casting annealing has a direct impact on energy conservation play an important role. I plant the tail of the annealing furnace trolley seal, the use of brick block mud seal method, the car is about to put under the trolley edge and masonry according to the distance between the size of the block with a brick, mud outside the layer of mud paste, this Method not only waste manpower, material resources, sealing is poor. When the furnace rises to a certain temperature, the outer mud crack, black smoke from the upper edge of the brick to the overflow, cold air from the bottom of the brick into the furnace, resulting in close to the door of the casting annealing quality not meet the requirements, but also Conduct two
