摘要： PURPOSE:To eliminate the need for forging process and to obtain uniform and fine spheroidal carbide by cooling at the specific velocity in a thin slab continuous casting method to form the continuously cast thin slab having the specific thickness and successively executing hot-rolling and annealing. CONSTITUTION:Molten steel M supplied in a tundish 2 from a ladle 1 is continuously poured into the thin slab continuous casting machine 3 and cooled so that cooling velocity at the time of solidification becomes 10 deg.-10 deg.C/s, to obtain the thin slab having 5-40 mm thickness. This thin slab is hot-rolled by rolling mill 4 to make a strip and coiled in annealing box 5. By this method, the forging process is eliminated the need for process integrated the continuous casting, hot-rolling and annealing works is executed. Further, eutectic carbide in the continuously cast thin slab is finely uniformized by the hot-rolling and further spherodized by the annealing, to obtain uniform and fine spheroidal carbide.

摘要： PURPOSE: To facilitate starting of continuous casting of a fine metallic rod by using a dummy bar of the construction wherein a heating element is incorporated in the cavity part in a pipe.
CONSTITUTION: After a dummy bar 1 is mounted to the leading end of a metallic pipe 5, it is inserted into a mold 9 prior to casting. After the insertion, a lead wire is connected to an electric power source 11 and heating is started. When the inside of the mold 9 is thoroughly heated to dry and is held throughly preheated, molten metal is teemed into a tundish 7, and casting is started. As a fine bar is being drawn, the dummy bar A is moved, and in accordance with this, a lead wire 6 is also moved in the drawing direction. In this case, the heating by a heating element 3 is not required after the start of heating and therefore the lead wire 6 is removed from the power source 6. When the pipe 5 pases pinch rolls 12, the head 1 is held melt stuck or entangled to a cast fine rod and in this state, the pipe 5 which is a dummy bar body is removed from the head 1 and is recovered.

摘要： PURPOSE:To obtain a cast ingot at a stable shape and superior quality by acting electromagnetic repulsive force upon a molten metal column to conduct the molten metal smoothly into a cooled mold and defining the shape of the ingot by the cooled mold. CONSTITUTION:A dummy bar 17 is beforehand located in a cooled mold 8, and cooling water 16 is flowed into the mold 8 to cool this; At the same time, the cooling water 16 is injected from the lower part of the mold 8. An electromagnetic coil 11 is kept energized. A furnace 1 is tilted to pour molten metal 9 onto the dummy bar 17 through a spout 6 and a heat resistant and heat insulating vessel 7, thereby allowing the dummy bar 17 to descend while the allowing the melt surface to ascend quickly, and starting casting. During this time, the molten metal 9a is curved to the inner side by pinching force by the coil 11, and a head H is held constant. Hence, the molten metal 9a can be smoothly flowed without causing stagnation of flow which is the cause for occurrence of cold shut or the like. Following to this, a solidified shell is formed in the molten metal 9a in the mold 8 by the heat deprived of from the mold walls, and is cooled by the cooling water 16. A cast ingot 15 is drawn by a cylinder 18.

摘要： PURPOSE:To cast a metal which does not cause any surface defect such as sweating, reverse segregation and the like by providing an electromagnetic coil in the lower part of a bottomless mold and applying side pressure by electromagnetic repulsive force to a cast ingot at the time of semicontinuous casting of the metal by drawing the cast ingot from the bottom part of said mold. CONSTITUTION:A dummy bar 12 is beforehand located in a bottomless mold 2, and the bar 12 is lowered with supplying of molten metal 3. During this time, the melt level in a spout 1 is measured at all times by a melt level measuring device 4 and the shape of a cast ingot by a cast ingot shape measuring device 10, respectively, and the signals thereof are inputted to a control arithmetic device 5. While said level is stable, the device 5 emits a command by the equation I. When the level is fluctuating, the change is measured with the device 4, and is fed forward to the command value MV0 of the equation I, whereby controllability is improved. Namely, it is corrected like the formula II. Since this method acts pinching force upon the solidified shell, a cooled mold 7 is short, hence, the solidified shell formed there withstands the static pressure of the molten metal in the inside although it is extremely thin.

摘要： PURPOSE:To produce a thin strip directly from a molten steel and to contrive a considerable cost reduction by forming a nozzle for conducting the molten metal to a specific shape expanding gradually toward the outlet and specifying the outlet side and specifying the area ratio between the inlet side and outlet side to>=1. CONSTITUTION:The molten metal in a tundish 3 is poured through the nozzle 4 into the casting mold part of a pair of water-cooled rolls 2 of a strip caster and the ingot strip 5 is diagonally drawn out of the outlet side thereof. The inlet side 4a of the nozzle 4 is formed square or circular and the outlet side 4b is formed to a flat shape. The sectional area thereof is continuously changed from the inlet side 4a to the outlet side 4b and the ratio between the sectional area A on the inlet side and the sectional area B on the outlet side B is speci fied to>=1. The inlet side is formed to the shape at which the temp. is maintained constant. Since the shape thereof expands gradually toward the outlet side, the molten metal is smoothly and broadly run. The strip is thus directly produced from the molten steel and the cost is considerably reduced.
