| 摘 要： | 针对出现的430、0Cr13R、409等铁素体不锈钢冷轧板夹杂缺陷,研究了中间包覆盖剂的碱度(1.10～5.98)对钢的洁净度的影响,分析了R=5.98高碱度中间包覆盖剂在浇铸过程中碱度、Al2O3和SiO2含量的变化。结果表明,在连铸过程中R=5.98高碱度中间包覆盖剂用原渣的R=5.98降至R=3.0,高碱度中间包覆盖剂具有良好的吸收钢中夹杂能力,对钢液的供氧能力弱,能够显著改善钢的洁净度。

| Abstract: | In accordance with inclusion defects occurred on cold rolled sheet of 430, 0C113R, 409 etc. ferrite stainless steels, the effect of basicity (1. 10 ~ 5. 98) of tundish covering flux on cleanliness of steel is studied, and the change of basicity, Al2O3 and SiO2 content in tundish covering flux with basicity R = 5. 98 during casting process is analyzed. Results show that in casting process , the basicity R =5. 98 of high basicity tundish covering flux decreases from original flux R = 5. 98 to R =3. 0, the high basicity tundish covering flux has excellent ability to absorb the inclusions in steel and has low ability of transport oxygen to liquid steel, the high basicity flux can remarkably improve cleanliness of steel. |
