摘要： A method of oscillating a mold of a vertical continuous caster of the type having a pair of longer side frames and a pair of shorter side frames. The mold is oscillated vertically during the casting. A pair of mold walls, e.g., the longer side frames, are moved towards and away from the cast metal in synchronization with a vertical oscillation of the mold, so as to control the condition for supplying a mold powder into the gap between the mold walls and the cast metal.

摘要： In a process of withdrawing castings while vertically oscillating a mold formed with long side walls and short side walls, the long side walls are moved apart from the castings by operating a hydraulic cylinder in the time zones for which the castings are applied with a large frictional force. On the contrary, the separated long side walls are made to move together to the casting in the other time zones for which the casting is not applied with the large frictional force. By repeating the separation and approaching of the long side walls, it is possible to obtain castings which are reduced in the depths of oscillation marks and suppressed in segregations at oscillation mark trough portions.

摘要： A hot-rolling process prevents surface deterioration of the stainless steel sheet which forms during hot rolling of a stainless steel slab after heating in a heating furnace, and does not cause damage to the heating furnace nor a decrease in yield of the steel sheet. The hot-rolling process for a stainless steel slab includes heating a stainless slab containing 10 weight percent or more of chromium in a heating furnace and hot-rolling the slab. A surface treatment, which is used prior to the heating, composition is composed of a mixture containing at least one of a Ca compound and a Ba compound and a binder for binding the mixture to a slab surface and for forming a coating film on a slab surface.

摘要： An ultra-low carbon steel slab having a carbon content of about 0.01 mass percent or less is produced by casting at a casting speed of more than about 2.0 m/min using a mold provided with a casting space having a short side length D of about 150 to about 240 mm and an immersion nozzle provided with discharge spouts each having a lateral width d, the ratio D/d being in the range of from about 1.5 to about 3.0. Accordingly, a ultra-low carbon steel slab can be obtained having superior surface quality without performing slab conditioning such as scarfing.

摘要： A method and apparatus for continuous casting of an elongated thin metal strip achieves substantially high yield without allowing break-out or sticking. The method for casting a continuous elongated metal strip includes a step of driving endless belts at a varying speed so as to apply jerks to the slightly and half-solidified metal that release the metal from the surfaces of the stationary side walls. Applying jerks to the casting chamber by varying the driving speed of the endless belt ensures that the solidifying metal will travel smoothly and thus ensures a high manufacturing yield.
