sample(Fluxes used for the casting of medium carbon, low carbon and super ultra low carbon (SULC) steel grades were sampled to compare properties. 对中碳钢、低碳钢和超超低碳钢连铸用保护渣进行了取样，以便比较其特性。)
ladle sample(A substantial decrease (> 0.005 percent) in the soluble aluminium content between the last ladle sample and mold is an excellent indication of a reoxidation problem at the caster. 结晶器(钢水中)溶解铝含量如果比钢包最后一次试样溶解铝含量大幅度降低(>0.005%),那么这是连铸机存在二次氧化问题的最好标志。)
