摘要： A cooling mold having first and second water cooling jackets which are provided inside the mold, a primary cooling water jetting mouth which is located at a distance of 15 to 40 mm from a meniscus of the molten metal, and a secondary cooling water jetting mouth which is located at a position with an interval of 20 to 45 mm between a contact point of a primary jet of cooling water and another contact point of a secondary jet of cooling water on an ingot. By use of the cooling mold having the primary and secondary cooling water jetting mouths which are respectively set at an angle of 15 to 30 degrees and of 30 to 60 degrees relative to the ingot surface, the primary jet of cooling water from the primary mouth impinges on the molten metal cooled in the cooling mold at a short distance from the meniscus to establish a transition boiling zone and a film boiling zone, and then, the secondary jet of cooling water from the secondary mouth impinges on initial zones of the transition boiling zone and the film boiling zone to break-out a vapor film generated in the initial zones so as to provoke a nucleate boiling and thereby to produce a firmer solidified shell in the ingot, whereby the ingot can be properly and effectively cooled without danger of breakout so that stable high rate casting and a high quality ingot can be achieved.

摘要： The shut-off device includes (1) a stopper capable of blocking a stream of melt flowing in the guide conduit which introduces the melt from a furnace into a tundish therethrough, if the occasion arises, and (2) a receiving plate disposed below a cooling mold so as to receive a leakage melt and having a heat sensor, the heat sensor being adapted to detect the heat of the leakage melt and communicating with a converter for transmitting an operation signals to the stopper. In such a specially designed structure, if the melt breaks out of the cooling mold, the leaked melt is received by the receiving plate and its heat is detected by the heat sensor. According to the detection of the heat, corresponding electric signals are instantly transmitted from the converter to the stopper and thereby the stopper is actuated so as to block the melt flow in the guide conduit.

摘要： A golf club head made of a hollow metal comprising a face and a body, wherein at least the face is made of a rapidly solidified Al-based alloy having a high strength, high elasticity and light weight. This golf club head makes it possible to stroke a ball without elastic deformation of its face and also to fly the ball farther with the initial speed thereof maintained, by using the Al-based alloy at least in the face. In addition, the use of the Al-based alloy makes it possible to form a large head and a long shaft so that balls can be stroked to fly over a long carry in an accurate direction.
