摘要： PURPOSE:To execute casting at high velocity without relating to thickness of a pouring nozzle by laying one pair of side weirs on pair of top pulleys through belts and arranging side face mold contacting with back face of the side weir and synchronously shifting with cast slab toward cast slab shifting direction. CONSTITUTION:Molten metal surface 8 is formed at upper part of the position formed with the belts 1, 1', top rolls 3, 3' and the side weirs 10 and parallel shifting the belts 1, 1' downward. Therefore, the thickness direction of the molten metal surface 8 and the opening area can be made to wide and the pouring nozzle 7 is submerged below the molten metal surface having wide area, to execute pouring. The poured molten metal comes to the cast slab below the molten metal surface 8 and shifts downward in the range formed with the belts 1, 1' and both side face molds 11. At the same time, as both side face molds 11 are shifted downward at the same time together with the cast slab, the solidified shell is formed under stable condition and the quality of the cast slab is improved and the side faces thereof is smoothly formed. Further, the wear caused by friction of the side face mold is prevented.

摘要： PURPOSE:To shorten length of a submerged nozzle and to prevent the development of clogging of the submerged nozzle caused by pouring of molten metal by arranging fluid pressure supporting means in inner side of curving part of belts at upper part of a mold part. CONSTITUTION:At the time of continuously casting thin slab S, etc., both curving parts at upper part of the mold part 10 are supplied with the fluid pressure supporting means 1 from the inner sides. Further, at lower part of the fluid pressure supporting means 1, belts 15 and side dams 16 are rotated and shifted while cooling with means for pouring cooling water to the belts 15 and the molten metal W is continuously supplied into the mold part 10 from the submerged nozzle 4. By this method, the most upper part of water cooling of the belt 15 is made to be possible to position just below the curving completed part and position of meniscus 10a can be raised. Therefore, the length of the submerged nozzle 4 is reduced and the development of nozzle clogging can be prevented.

摘要： PURPOSE:To reduce much quantity of loads to pins and rollers at blending parts of guide rolls by arranging side dam guide means, which radius of curvature at the bending part guiding the side dam is gradually reduced toward shifting direction of the side dam. CONSTITUTION:Grooved guide rails 18a are respectively arranged at the inner faces of one pair of the guides 18. The curving line of lower bending part at A side of mold part of the guide rail 18a is gradually reduced by large, middle to small of each radius of curvature rho1, rho2, rho3 from the upper side. Links 19b fixed to the side dam blocks 19a are endlessly connected by the pins 10 to constitute the side dam 19 and held to one pair of belts 3. At the time of continuously casting the slab 21, the side dam 19 is shifted by rotating a sprocket 7 and then as the guide rail 18a gradually reducing the radius rho of the curvature from the vertical part is arranged, the reduction force of the roller can be released.

摘要： PURPOSE:To prevent development of skinning caused by solidified material on molten metal surface and to beforehand prevent breakage of a pouring nozzle by arranging an induction heating device at back face of a belt near the molten metal surface in a mold part formed by belts and molds and heating the molten metal. CONSTITUTION:The mold part M having rectanglar cross section extended to vertical direction is formed by one pair of endless metal belts 1, 1' parallel running through top rolls 3, 3' for positioning and one pair of side face molds 11, 11'. The molten metal is supplied into the mold part M from a pouring nozzle 7 and cooled by cooling pads 5, 5' arranged at back face of the metal belts 1, 1' to cast the cast slab 7. In the above twin belt type continuous casting apparatus, one pair of electromagnetic coils 9, 9' mutually facing to the other's are arranged to the back face of the belts 1, 1' near the molten metal surface 8 of the mold part M. By this method, the molten metal is heated by Joule's heat generated with line 10 of magnetic force. Further, the molten metal surface 8 is not solidified and the breakage of the molten metal nozzle 7 caused by skinning of the solidified material can be prevented.

摘要： PURPOSE:To permit uniform contact of a mold and the solidified shell in the mold and to prevent cracking and deformation by measuring the temp. of a mold wall and controlling water volume in such a manner that the temp. is kept within a specified range. CONSTITUTION:The control unit for spray water is bisected in a longitudinal direction and is provided with respectively independent water flow rate control valves 5, 6 in the respective units. The control of the water volume is executed with lower spray pipes 4 of a 2nd zone in the lower stage. On the other hand, the 1st zone of the upper stage is the liquid contact zone of the mold 1 and a molten steel 11. Since the change in the quantity of heat transmission is small in this zone, the upper spray pipes 3 are preset at the optimum rate determined by the kind of the steel and casting speed to spray the cooling water at the specified flow rate. The mold temp. is measured by thermocouples 9, 10 embedded in the mold in the position near the meniscus and at the prescribed distance from the meniscus. The measured values are inputted to an arithmetic unit 7 to control the flow rate control valve 6. The breakout by which the shell is broken right under the mold is thereby prevented and the casting speed is increased.

摘要： PURPOSE:To reduce the electric power capacity by minimizing the distance between a mold and a coil, by arranging surface cooling spray pipes at the upper part and corner cooling spray pipes and coils for electromagnetic stirring at the lower part to the longitudinal direction of the mold. CONSTITUTION:To the longitudinal direction of outer surface of the mold 1 for continuous casting apparatus, the spray pipes 24, 25, by which executes cooling by spraying water, are divided into steps as the upper and lower. The upper step's spray pieces 24 inject the cooling water on a part of mold 1 face and its length is to be about 30-50% of the total mold 1 length. Further, the lower part's spray pieces 25 inject the cooling water against the corner part of the mold 1, and the coils 26 for electromagnetic stirring are arranged at the facing part to the mold 1 face and the gap between the mold faces and the coils 26 is to be about 1010-30mm. In this way, by minimizing damping of the electromagnetic force, cooling of the mold 1 is executed.
