連続鋳造時の鋳片の温度変化のシミュレータによる解

抄録

Using an electric simulator for the solidification of slab, the change and distribution of slab temperature concerning both conventional mould and continuous casting were obtained. Experimental results made clear the effect of the time of air-gap occurrence and the effect of the coefficient of heat transfer of the boundary between slab and mould.
In the case of continuous casting, the temperature change during solidification process was clarified; the temperature of slab surface dropped rapidly in a mould after pouring, then rose owing to air-gap occurence, followed by dropping again as secondary cooling, subsequently the temperature rose due to air-cooling in the following step.
Accordingly, using such a simulator, the change and distribution of slab temperature can be obtained easily under different casting conditions.
