STEEL SHEET IN WHICH MICROSEGREGATION OF PHOSPHOROUS IS DISPERSED AND CONTINUOUSLY CAST SLAB 燐のミクロ偏析が分散された鋼および連続鋳造鋳片 - 特許庁
When a steel is subjected to continuous casting, the componential values of the steel after secondary refining are analyzed, and, using a microsegregation model in accordance with the value, based on the relation between microsegregation and a solid phase ratio, an internal crack critical strainεcr is calculated. 鋼の連続鋳造を行うに当たり、二次精錬後の鋼の成分値を分析し、その値に応じてミクロ偏析モデルを用い、ミクロ偏析と固相率との関係に基づいて内部割れ限界歪εcrを計算する。 - 特許庁
