燃烧中和滴定法测定钢中低硫

Firing-Correcting Determination of Low Sulfur in Iron

探讨了用燃烧中和滴定法准确测定钢中低硫的条件 ,即助熔剂、氧气流量和时间、燃烧炉温度、吸收液颜色的选择和控制。该法可满足钢中低硫 ( S<0 .0 1% )

In this paper,the optimum conditions for firing-correcting determination of low sulfur in steel is studied,then the flux,the oxygen discharge is with time,burn the temperature,absorb the choice of the liquid color and control.It is shown that the low sulfur (S<0.01 %) can be determined accurately by the proposed method.
