摘要： PURPOSE:To continuously cast a complex steel having a little mixture between the layer and clean boundary by supplying different kinds of metals at upper and lower parts of traversed static magnetic field having a distance from the molten surface in a mold under relation of the specific equation about thickness of solidified surface layer, drawing velocity and solidified velocity of cast slab. CONSTITUTION:Magnets 8 are arranged at the position, which the distance (l) toward casting direction from the molten surface in the mold 1 has relation of the equation to the thickness (d) f solidified surface layer, the drawing velocity (v) and the solidified velocity (f) in the slab 9 and the static magnetic field 10 traversing whole width of cast slab 9 is formed. The molten metal for forming the surface layer is supplied above the static magnetic field 10 by a submerged nozzle 2 and the molten metal for forming the inner layer is supplied below the static magnetic field 10 by a submerged nozzle 3. By suitably controlling the balance of each supplied rate, the fluidity of the molten metal is braked at the magnetic force part 10 and the lower part supplied metal shell is solidified at inside of the upper part supplied at inside of the upper part supplied metal shell 5 on the surface layer. By restraining the mixture between layers to the min., the complex steel 9 having clean boundary is continuously cast.

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.
