在我国钛钢系目前是第二大钢种中,其中最多的是高强度低合金钢。这些钢多数含钛0.06～0.12％,也有的低至0.005％,除高合金钢外含钛大于0.2％的钢种为数不多。目前,在测定钛的方法中,二溴苯基荧光酮比色法(ε_(580)=1.03×10~5)、二安替比林甲烷比色法(ε_(420)=1.51×10~4)等的测定速度都不能满足炼钢炉前快速分析的要求;二安替比林甲烷法(国标),虽然推荐可测至
Titanium steel system in our country is currently the second largest steel, most of them are high strength low alloy steel. Most of these steels contain 0.06-0.12% of titanium, and some are as low as 0.005%, except for the few grades of steels that contain more than 0.2% titanium in high alloy steels. Presently, in the method for the determination of titanium, the dibromophenylfluorone colorimetric method (ε 580 = 1.03 × 10 5) and the diatopicinmethane colorimetric method (ε 420 = 1.51 × 10 -5) 4) and other measurement speed can not meet the requirements of the rapid analysis of steelmaking furnace; two Antimine methane method (GB), although the recommended measurable
