摘要： CONTINUOUS CASTING PROCESS FOR COMPOSITE METAL MATERIAL A method of producing a composite metal material such as clad bloom by continuous casting comprises the steps of supplying molten metals of different compositions by using two immersion nozzles into the strand pool at different positions and of forming a static magnetic field zone on the boundary between the two types of metals to prevent the mixing of metals of different composition. The method enables production of a composite material exhibiting a sharp boundary between the two types of metals used and enabling the thickness of the respective metal layers to be easily controlled by adjusting the location of application of the static magnetic field or the withdrawal speed of the strand of cast metal.

摘要： A twin belt type continuous casting machine for producing thin slabs has a pair of belts and a pair of edge dams for forming a metal pool. These edge dams are movable in the transverse direction of the belt. A plurality of cooling/heating chambers partitioned in the transverse direction of the belt are provided on the rear surface of the belt in the vicinity of respective side end portions of the belts. A plurality of supporting means which are capable of pressing the rear surface of the belt are respectively provided in the plurality of cooling/heating chambers. The movement of the edge dams is synchronized with the operation of the plurality of supporting means, A fluid introduced into each of the cooling/heating chambers is changed into a heating fluid or a cooling fluid in synchronism with the movement of the edge dams.

摘要： PURPOSE:To improve surface characteristic and shape of a metal strip by arranging short side mold pushing block between fin rolls arranged at back face of a belt or as freely advancing/retreating corresponding to width of the metal strip produced at upper part. CONSTITUTION:Pushing mechanism composing of the short side mold pushing block 17, rod 18 and pushing device 19 is arranged between fins 16 of the fin rolls 15. The short side molds 4 are shifted corresponding to the width of the metal strip and also the short side mold pushing blocks 17 are advanced/ retreated. By such a constitution, the surface characteristic and shape of the product are improved.

摘要： PURPOSE:To permit stable continuous casting of an ingot by blowing gaseous oxygen to the extent of preventing the generation of form during solidification and quality deterioration for a specified period to a molten steel in which a specific deoxidizing element is melted and making the absorption thereof uniform, thereby establishing a specific relation between a casting speed and ingot thickness. CONSTITUTION:The gaseous oxygen or gas contg. oxygen to the extent of preventing the generation of CO foam during solidification and the deterioration in quality is blown through a gas blowing tuyere 7 into the molten steel 4 in a tundish 3 into which the deoxidizing element, preferable for quality, essentially consisting of Mn or Si or both thereof and having a less tendecy to floating and separating is melted. The uniform mixing time tmix of the molten steel 4 is set at the relation satisfying equation I with regard to the average residence time t0 of the molten steel 4 so that the adsorbed oxyegen is made uniform in the molten steel 4. The molten steel is then poured into a casting old 8 at the relation between the casting speed Vc(m/min) and ingot thickness d(m) satisfying equation II, kby which the contents of the total oxygen in the top, middle and bottom surfaces of the solidified ingot 9 are made uniform. The short side length of the ingot is made

摘要： PURPOSE:To improve the shape and quality of an ingot by disposing a fin roll pair constituted of a magnetic material on the rear surfaces of belts near the meniscus. CONSTITUTION:Plural pieces of the fin rolls 16, 16' are disposed on the rear surface side of the belts 5, 5' so as to contact with the belts near the meniscus 19 of a molten metal 10. The fin rolls 16, 16' are provided with disk fins 23 consisting of the magnetic material having high coercive force on roll shafts 24 and are so constituted that the belts 5, 5' and the fins 23 directly contact with each other. The molten metal 10 poured between the belts 5 and 5' from a tundish 9 is cooled between the belts where the meniscus part thereof is held between the fin rolls 16, 16' having the high coercive force to form solidified shells. The belts 5, 5' which are going to generate the buckling deformation by the thermal stress contact tightly with the fin rolls 16, 16'. The flatness of the belt surfaces is thus assured and the shape and quality of the ingot are improved.
