摘要
为了减少大板坯连铸机粘结及粘结漏钢的发生,对结晶器保护渣的消耗量、保护渣液渣层厚度及粘结的受力机理进行了研究和分析,认为保护渣消耗量低及保护渣液渣层厚度不够时容易产生粘结和粘结漏钢。通过采集现场的参数进行理论计算并与实际生产值进行对比,结果表明,保护渣的消耗量控制在0.4～0.6 kg/m2、保护渣液渣层厚度控制在10mm以上后,未发生粘结漏钢事故,且粘结发生次数降低了60%。
In order to reduce sticking and sticking type breakout of slab casting, consumption of protection slag in mold, thickness of molten slag and forcing mechanism of sticking were analyzed and calculated. It is thought that low consumption of mold slag and not enough thickness of mold slag will easily lead to sticking and sticking breakout. Through many experiments, the results showed that the consumption of mold slag was suitable between 0.4 kg/m2 and 0.6 kg/m2. Also the thickness of molten slag should be at least 10mm. Operating practice indicated that sticking type breakout did not happen and sticking rate was reduced by 60%.
