钢液倒包真空处理
shift ladle degassing

  gangye dao匕ao zhenkong eh。}(钢液倒包真空处理(shift ladle degassing,SLD)一种钢液真空处理技术。其目的是脱除钢液中的气体([H〕和仁N」)。此方法是联邦德国于1955年开发使用的,其装置是一个带有移动顶盖的真空室,上置中间包;把浇铸用的钢包放在室内;顶盖上有观察孔和使钢液注入室内的注钢孔。处理时先将注钢孔用铝箔密封,启动真空泵,将真空室抽空,把要脱气处理的钢液倒入普通钢包内。将此钢包吊至真空室的上方,并将钢液注入中间包;钢液熔化铝箔后,进入真空室即被分散成细小的液滴,脱气便在液滴自由降落过程中基本完成,故此法也称作倒包滴流脱气法。根据注口的大小不同,中间包的浇注速度在5~功t/min之间变化。(见图)由于这种工艺的脱气是滴流在真空室内下降过程中完成的,不是整桶钢液同时进行真空脱气,因而可以克服钢液静压力的不利影响。当钢水流进入已抽空的容器时,由于真空(低压)的作用,钢流被分散成很多细小的液滴,因而产生了很大的表面积,在进入真空室的短暂过程中,其所含的全部气体几乎都被释放出来。这时脱气反应速度的公式为裔盖 钢液倒包真空处理示意图 1一中间包;2一真空室;3一浇铸用的钢包止书黔一释(、一仁G0j’分离变量积分得 、蹂暴一赤争式中〔G二为才时刻钢液气体含量;仁偏」为钢液中原始气体含量;了三为与钢液平衡时的气体含量;F为气相一钢液界面积,cm‘;V为钢水体积,。m“;D为气体在钢液中的扩散系数,1600℃时,DH为3.5火10一3c。么/。,DN为5.5只10一seoz/。;S为边界层厚度,波动于。,2~。.。。。01cm之间。从式中可以看出,该真空处理技术可以增大单位脱气面积(F/v少和传质系数K(D/S),从而大大地提高了脱气速率。但是这种方法存在着一个很大的缺陷,在处理过程中钢液的温降严重,例如30~50t的钢液,经处理后温降可达10。℃,这就意味着要增加初炼炉的能耗,延长初炼时间,降低生产率和初炼炉的炉衬寿命,增加耐火材料的消耗。 (杨念祖)
