摘要： PURPOSE:To continuously mass-produce a sheet having wide width directly from molten metal and to contrive the cost down by pouring the molten metal flow to the member having the surface shape with continuous dent face to the roll rotational shaft direction. CONSTITUTION:The molten metal 2 in a ladle 1 is poured into a vessel 4 through a stopper 3, and supplied into between the rolls 7, 8 from a slit nozzle 5 arranged in the vessel 4 through an inclined plate 6 and rolled. The rolled sheet 11 is bited into pinch rolls 9, 10. The inclined plate 6 is arranged at the same width as the width of the slit nozzle 5, which is arranged in the vessel 4, and this width is the same as the width of the sheet to be produced. The surface of the inclined plate 6 is formed as dent face for guiding the molten metal flow.

摘要： PURPOSE:To assure the sealing of a molten steel by constituting side dams of refractories and metal, projecting the refractories to a molten steel side and positioning the bottom ends thereof upper than the narrowest part between drums. CONSTITUTION:The side dams are constituted of cooling plates 7, 7' consisting of the refractories 6, 6' and metallic members. The refractories 6, 6' are disposed by being recessed by a size (m) to the molten steel pool side from the barrel end faces of the drums. The bottom ends of the refractories are positioned upper by h1 from the line A-A passing the narrowest part between both drums so as to exist near the rolling start point of the solidified shell. The exertion of the force by the press contact of the solidified shell to the side refractories 6, 6' is obviated by such mechanism and the cooling plates 7, 7' release said load via springs 9, 9' of pressing devices to back plates 8, 8'. The wear of the refractories 6, 6' is thus prevented and the molten steel is surely sealed.

摘要： PURPOSE:To provide a titled device which casts continuously a thin-walled slab irrespectively of the size of a nozzle tip of oscillating mold and synchronously moving belt type continuous casting by providing a servocontrol nozzle in the upper part of the casting mold which oscillates finely at a high cycle thereby narrowing the mold space. CONSTITUTION:The molten steel in a tundish 1 is received by an immersion nozzle 2 into a servocontrol nozzle body 3 on a mold 5 which oscillates finely and vertically at a high cycle and is poured and sagged into the mold 5 through the narrow nozzle gap corresponding to the thin wall thickness. The molten steel is continuously cast and sagged by the narrow gap irrespectively of the size of the nozzle 2 and therefore the inside of the mold 5 is kept free from undue stress. Since the molten steel is smoothly sagged by fine oscillation without rippled surface, the satisfactory thin-walled slab is obtd.

摘要： PURPOSE:To form the ends of a billet to be drawn straightforward from an outlet side into an arc shape and to prevent the crack in corner parts by forming the inside surface of the stationary side plates of a curved type continuous casting machine having a casting mold consisting of stationary side plates on short sides and movable belt-like bodies on long sides into a recessed shape. CONSTITUTION:The end parts of stationary side plates 10A, 10B on a billet 29 side are formed into a recessed shape, and the end parts of the solidified shell 36 of the billet 29 are made into an arc or resembling shape. Then the stress concentrating at the corners of the billet 29 in the stage of straightening the bend of the billet 29 is received by the arc-shaped shell 36 and is absorbed by the deformation over the entire part of the shell 36. Even if the continuous casting speed is high, the large ratio between the width of the billet and the initial casting radius R is taken and even if the initial casting radius is made small, the cracking at the corners of the billet 29 is prevented.

摘要： PURPOSE:To perform optional bending work quickly by leading a material sent out from rolls in between by a controlling device that makes bending radius or by a device that makes materials of different sectional thickness in the direction of width uniform thickness by a roll in bending of a plate etc. CONSTITUTION:A material 16 restrained by a guide plate 14 is rolled by a roll 18 having a reduction slightly strengthened on the bending side, and the tip is caught by the clamping jig of a guide arm 27 that rotates around a supporting pin 32. By the advance of the material 16, the guide arm 27 rotates and performs specified bending work. Bending can also be performed by providing a guide roll on exit side. Otherwise, a side guide 62 is provided on the exit side of the roll and the section of the material 16 is rolled to unequal thcikness. Then, the side guide 62 is removed and rolled again to equal thickness by a roll 52, and a bend is formed in the exit side. By this way, optional bending work can be made easily and surely.

摘要： PURPOSE:To prevent solidification and sticking of a molten metal on the surface of an immersion nozzle and to stabilize a casting operation by forming the wall surface of a molten metal immersion nozzle which is an immersion type molten metal charging nozzle of a material consisting essentially of BN and Si3N4. CONSTITUTION:Layers 24, 25 consisting essentially of BN or SiN3N4 or a mixture composed of both are coated on the outside and inside surface of the part to be dipped in a molten metal in an immersion type molten metal charging nozzle 3 for charging a molten metal into a casting mold, and are calcined by heating or the like to form a coating layer. A sleeve consisting essentially of BN or Si3N4 is fitted on the outside wall surface in the part to be dipped in the molten metal. The thickness of the BN and Si3N4 layer is made about severalmu-several hundreds mu. A billet having good quality is produced stably by using such nozzle. Since the molten steel does not stick on the nozzle 3, the cracking and failure of the nozzle 3 are prevented.
