| 摘 要： | 研究了0-6％BaO含量对包钢CSP流程浇铸Q235B、SS400等中碳钢、主要成分(％)为31．60CaO、27．20SiO2、10．48C、4．85Al2O3、碱度为1．16的结晶器保护渣熔化温度、析晶温度和析晶率的影响。试验结果表明,在实验渣中加入≤2％BaO,可有效地改善保护渣的润滑性能,抑制晶体析出,改善熔渣的玻璃性能;BaO含量≥4％时,完全抑制晶体析出,得到良好的玻璃态渣膜。

| Abstract: | Influence of 0~6% BaO content on melting temperature, crystalline temperature and rate of mould pow- der with main ingredient 31.60CaO,27.20SiO?,10.48C,4.85Al2O3 and basicity 1.16 for casting Q235B, SS400 etc medium carbon steels by CSP flow sheet at Baotou Steel has been studied. Test results showed that added ≤2% BaO in test mould powder was available to improve lubricant and vitreous performance of flux and restraine precipitation of crystals, and as BaO content was ≥4%, the precipitation of crystals was completely restrained to get optimizing vitreous flux films. |
