氧气顶吹转炉炼钢不仅升温快,而且还具有较大的脱碳速度的特点。在吹炼过程中,必须使升温与脱碳速度以及磷、硫等杂质的去除速度协调起来,使终点温度与成份同时满足要求。因此,温度控制是氧气顶吹转炉炼钢操作中的重要环节。众所周知,在吹炼过程中若温度忽高忽低,就会影响化渣速度,造成喷溅,增加吹损,还会沾枪沾烟罩,影响炉龄和枪龄,严重者还会出现事故;若终点温度或出钢温度过低,将出低温钢,产生大量短锭、桶底及结疤等废品;若温度过高,钢中 Oxygen top converter steelmaking not only heats up quickly, but also has a greater decarburization speed characteristics. In the blowing process, we must make the temperature and decarburization speed and phosphorus, sulfur and other impurities to speed up the removal rate, the end temperature and composition to meet the requirements at the same time. Therefore, the temperature control is an important part of BOF steelmaking operation. As we all know, blowing in the process if the temperature fluctuated, it will affect the slag speed, resulting in splashing, increasing blow loss, but also stick gun hood, affect the furnace age and gun age, serious accidents will occur ; If the terminal temperature or tapping temperature is too low, will be out of low temperature steel, resulting in a lot of short, bottom and scarring and other waste; if the temperature is too high, the steel
