Description
冷却水として、水よりも高い熱伝導率を有する高熱伝導粒子が添加された冷却水を用いる金属の連続鋳造法。
2)測温部分:鋳塊内部(上面から35mm、中心から10mm)
3)測温範囲:450~300℃
4)昇温条件:500℃の電気炉内で試料10を2時間保持し、試料温度を480℃まで上昇させる。
6)冷却水容器内寸法:上面φ269.66mm×下面φ245mm×高さ205.5mm-試料体積mm3
7)冷却水温:開始10℃
8)冷却条件:試料温度が450℃まで上昇した後、火ばさみで取り出してから、即座に冷却水中に試料全面を浸漬する。この時、試料10と冷却水容器は非接触状態で、300℃未満に試料10が冷却されるまで、火ばさみで冷却水中に浮遊した状態に試料10を保持する。この時、450℃~300℃までの時間を冷却時間として定義した。
・熱電対11:K熱電対クラス2
・測定頻度:100ms。
2)計算手法:有限要素法、倍精度、圧力ベースソルバ、混相流モデル:VOF法、乱流モデル:k-ωSST、非定常計算
3)物性値:表1に示す。
・ρ_c=ρ_s×a+ρ_l(1-a)
・Cp_c=(ρ_s×a×Cp_s+ρ_l(1-a)Cp_l)/ρ_c
・Tc_c=k_l{k_l(1-a(2/3))+k_s×a(2/3)}/{k_l(1-a(2/3)+a)+k_s(a(2/3)-a)}
・体積分率を立方体で置換し一次元熱伝導で計算
・μ_c:スラリーについては、不明なため、水で計算
5)試料寸法:上面φ105mm×下面φ62×高さ125mm
6)冷媒体積:上面φ269.66mm×下面φ245mm×高さ205.5mm-試料体積mm3
7)試料位置:冷媒中心
8)初期温度:冷媒18℃、試料500℃
9)測温位置:上面から35mm、中心から10、20、30mm
10)冷却時間:10mm地点が450℃に到達してから300℃に到達するまでの時間。
