Title:
連続鋳造におけるブレークアウト予知方法
Document Type and Number:
Japanese Patent JP7421103
Kind Code:
B2
Abstract:
To provide a method, in slab continuous casting, capable of predicting the generation of breakout caused by the remelting of a solidification shell at high precision compared with the conventional method.SOLUTION: A method of predicting the generation of breakout caused by the remelting of a solidification shell in slab continuous casting comprises the steps of: defining a difference between a width of a slab and an inner size width in a lower edge of a mold as a short side bulging amount, defining a short side bulging amount upon generation of breakout as a limit short side bulging amount, and obtaining a relational equation between the carbon equivalent of the slab and the limit short side bulging amount; measuring a width of the slab directly below the mold, and calculating the short side bulging amount; and when the calculated short side bulging amount becomes equal to or more than the limit short side bulging amount calculated by substituting the carbon equivalent of the slab for the relational equation, determining that breakout is generated.SELECTED DRAWING: Figure 1
