摘要： PROBLEM TO BE SOLVED: To provide powder for continuous casting and a continuous casting method capable of lessening prediction signal generation of constraint breakout since constraint breakout prediction signals generate frequently when continuously casting Al-Si killed steel in which a Ca content is 15 ppm or more.SOLUTION: The Al-Si killed steel including Ca decreases a heat removal amount from a solidified shell to a mold wall due to generation of bubbles into a powder film during casting and increase of film thickness, or causes large irregularities, and leads to frequent generation of the constraint breakout prediction signals. Thus, OHions in the powder film is reduced into molten steel to increase CaO in the powder, to thereby prevent bubble generation. In other words, the powder for the continuous casting used in the continuous casting of the steel includes 15 ppm or more Ca, 0.1 mass% or more Si, and 0.015 mass% or more and less than 0.035 mass% Al and has basicity B of 1.5 or more. The continuous casting method using the powder is provided.
摘要翻译：要解决的问题：为了提供连续铸造用粉末和能够减少约束断裂的预测信号生成的连续铸造方法，因为当连续铸造Ca含量为15的Al-Si杀死的钢时，约束破裂预测信号频繁地产生 ppm以上。解决方案：包括Ca的Al-Si杀死的钢由于在铸造期间由于气泡形成粉末膜而导致从固化壳到模具壁的去热量增加，或者导致大的不规则性，并导致频繁地产生约束突破预测信号。因此，粉末膜中的OH离子被还原成钢水，以增加粉末中的CaO，从而防止产生气泡。换句话说，用于连续铸造中的连续铸造用粉末包含15ppm以上的Ca，0.1质量％以上的Si，以及0.015质量％以上且小于0.035质量％的Al，并且碱度B为 1.5以上。提供了使用粉末的连续铸造方法。版权所有（C）2012，JPO＆INPIT
