分析篦冷机堆雪人的原因与预防策略探究

Exploration of the Causes and Prevention Strategies of Building Snowmen in the Grate Cooler

分析篦冷机运行问题,要从多角度出发。篦冷机故障主要为人为因素、设备因素等。其中,篦冷机“堆雪人”故障是一种形象性称呼,篦冷机在运转时若没有及时将细料、熟料推走,就会出现废料堆积越高,且形状如雪人般的余料。严重时,甚至可堵塞窑口。若忽视篦冷机堆雪人的原因,就会使耐热钢护铁报废,还会影响窑口的热工制度与通风,出现一系列的恶性循环。

To analyze the operation problems of the grate cooler,it is necessary to start from multiple perspectives.The failure of the grate cooler is mainly caused by human factors and equipment factors.Among them,the"building snowmen"failure of the grate cooler is a figurative name.If the grate cooler does not push away the fine material and clinker in time during operation,there will be a higher accumulation of waste and residues shaped like snowmen.In serious cases,the kiln mouth may even be blocked.If the reason for making snowmen in the grate cooler is ignored,the heat-resistant steel protective iron will be scrapped,the thermal system and ventilation at the kiln entrance will also be affected,and a series of vicious cycles will occur.
