摘要： A method of removing non-metallic inclusions from a molten metal comprises the step of simultaneously applying both a horizontal rotation of the molten metal and heating of the molten metal by induction heating. After the simultaneous application of rotational force and heat, the induction heating may be stopped while the horizontal flow of the molten metal is maintained, so as to promote the separation of the particles of the inclusions. The method is carried out by using an apparatus which has a vessel which contains the molten metal, a rotary magnetic field generating device surrounding the vessel, and an induction heating device also surrounding the vessel. Each of the rotary magnetic field generating device and the induction heating device may be divided into a plurality of circumferential segments and arranged such that the segments of both devices are alternately disposed around the vessel.

摘要： A method of removing non-metallic inclusions from a molten metal by allowing the molten metal to pass through at least first and second vessels which are intermediate between a ladle and a mold. The molten metal is made to stay in the vessel for a period not shorter than 40 seconds while a horizontal rotation is imparted to the molten metal in the first vessel. The molten metal is then transferred from the first vessel to the second vessel. The molten metal in the second vessel is then heated. This method is suitably carried out by an apparatus comprising a first vessel having a discharge opening at its bottom and surrounded by a rotational magnetic field generating device for centrifugation of the molten metal in the first vessel, and a second vessel for receiving the molten metal discharged from the first vessel and provided with a heating device for heating the molten metal received therein.

摘要： A nozzle for use in continuous casting comprising an inner surface region defining the nozzle port for passing a molten steel, said inner surface region being formed from a mixture having a composition containing 50 to 80 wt % of boron nitride (BN) and 20 to 50 wt % of zirconium oxide (ZrO.sub.2), and a sintering assistant composed of silicon carbide (SiC) and boron carbide (B.sub.4 C) mixed at a weight ratio of 1:1, the sintering assistant being added in amount of 5 to 10 wt parts to 100 wt parts of said mixture. The nozzle is produced by a process comprising the steps of: forming a uniform mixture of fine particles of boron nitride (BN), zirconium oxide (ZrO.sub.2), silicon carbide (SiC) and boron carbide (B.sub.4 C); forming the mixture into a cylindrical blank; and fixing the cylindrical blank in the bore of a nozzle member by means of a joint filling material.

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： 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： 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： One or more streams of molten metal poured into a continuous casting mold are acted on magnetically by static magnetic fields, covering substantially the entire width of the casting mold, thereby reducing the speed of the molten metal streams from the immersion nozzle, unifying the flow profile of the molten metal in the mold, preventing trapping and accumulating of mold powders and inclusions into the cast products. Magnetic poles are provided which are at least as wide as or wider than the minimum width of the cast products and the iron core is arranged on the same face of the casting mold with mutually opposite polarities in the drawing direction. Even if casting conditions change from time to time, defects in final products made of the cast metal are substantially reduced.
