    摘要: A crucible including a cylindrical partition member arranged concentrically therein for use in a silicon single crystal growing apparatus. The bottom of the crucible located on the inner side of the partition member has a thickness which is not less than 1.3 times and not greater than 4 times the thickness of the partition member and it also has a porosity which is between 0 and 0.2% in its inner layer and between 0.2 and 15% in its outer layer as compared with the porosity of the partition member which is 0.2% or less. By virtue of the foregoing, a D.F. ratio (ratio of dislocation free) of 80% or over can be expected.

    摘要: There are provided a cooling device and a cooling method for a hot-rolled strip in which the strip can be uniformly cooled from a leading edge to a trailing edge with coolant by properly realizing a great cooling ability and a stable cooling zone. Specifically, the following three methods are adopted. (1) Round nozzles 14 for ejecting inclined rodlike flows of coolant to a downstream side in the traveling direction of a strip 12 and round nozzles 14 for ejecting inclined rodlike flows of coolant to an upstream side in the traveling direction are arranged on an upper side of the strip 12 so as to oppose each other. (2) Round nozzles 14 for ejecting inclined rodlike flows of coolant from the upstream side of a roller table 9 toward just above the roller table 9 and round nozzles 14 for ejecting inclined rodlike flows of coolant from the downstream side of the roller table 9 toward just above the roller table 9 are arranged on the upper side of the strip 12 so as to each other. (3) Lower cooling nozzles 19 for ejecting coolant from between roller tables toward a lower surface of a strip 12 are provided on the lower side of the strip 12, and cooling nozzles 14 for ejecting inclined rodlike flows of coolant from the upstream side of a position where the coolant ejected from the lower cooling nozzles 19 collides with the strip 12 toward just above the position and cooling nozzles 14 for ejecting inclined rodlike flows from the downstream side of the position toward just above the position are arranged on the upper side of the strip 12 so as to oppose each other.
