摘要： PURPOSE:To effectively execute cooling of high temp. steel plate by correcting necessary cooling time from deviation between the standard cooling starting temp. and the actual cooling starting temp. and average cooling velocity and modifying shifting velocity for the steel plate. CONSTITUTION:The high temp. steel plate after hot rolling or after ejecting from a heating furnace, is forcedly water-cooled in order from end part of carrying direction, to make temp. of the steel plate at the time of stopping the water-cooling to about 250 deg.C. In this cooling method, the temp. deviation is calculated from cooling starting temp. found by the standard cooling starting temp. decided as function, such as thickness of cooling steel plate, etc., and the cooling starting temp. finding by measuring value before cooling starting, etc. Next, the standard cooling time decided for the thickness of cooling steel plate, the necessary cooling time is corrected by using the above temp. deviation and the average cooling speed between 250-150 deg.C at the time of cooling the steel plate, and the shifting velocity of steel plate is modified, so as to attain this cooling time. In this way, the material quantity at the end part of steel plate is stabilized and the productivity is improved.

摘要： PURPOSE:To prevent the generation of waves by falling fountain columns and to stabilize submergence depth by discharging cooling water upward from the nozzles under the water surface in a water tank to form water columns on the water surface and ejecting the water from ejection parts projected to a partition body provided on the water surface. CONSTITUTION:The many lower nozzles 13 attached to a lower header 10 are disposed in the water tank 3 which is provided with makeup water feed pipes 7, drain pipes 9, etc. and is opened upward. The lower nozzles 13 are positioned under the water surface of the water tank 3 and the cooling water supplied from water feed pipes 12 is discharged upward into the water. The water columns are thereby formed on the water surface so as to collide against the bottom surface of the steel sheet moving on the water tank 3, by which the bottom surface is cooled. The cooling water after cooling falls and at least part thereof is recovered into the water tank. The partition body 20 projected with the ejection part 23 having holes 22 in the injection direction of the nozzles 13 is provided between the top surface of the water tank 3 and the steel sheet (not shown). The fountain columns from the nozzles 13 are thereby dropped onto the partition body 20 after ejection from the holes 22 and the direct falling into the water tank 3 is obviated.

摘要： PURPOSE:To produce a good-quality long-sized billet molding without generating joint surfaces by loading and packing a powder material into container molds and compressing the material by a moving mold from the direction orthogonal with the longitudinal direction of the billet, thereby solidifying and molding the material. CONSTITUTION:The powder material 4' which is a powder or granular metal, ceramics or the mixture composed thereof is housed into a metallic mold for molding constituted of the container molds 2, 3. The moving mold 1 is then used and is pushed down to a position 1' from the direction orthogonal with the longitudinal direction of the billet to exert pressure to the powder 4' and to compress, solidify and mold the powder, by which the long-sized billet 4 of L/D>1 (L is the length of the billet, D is the representative length of the billet section) is molded. The solidification and molding in a reduced pressure or vacuum atmosphere is more effective at this time; the molding at the temp. below the solid phase point of Al or Al alloy is advantageous particularly in the case of using the powder prepd. by mixing SiC whiskers and Al or A$; alloy powder as a raw material. The long-sized billet is thereby molded without requiring joining in the molding stage.
