摘要： PURPOSE:To start a continuous casting machine without developing a coagulation hull by interposing a heat insulating material between a molten metal nozzle and a dummy bar between casting molds, and moving the dummy part together with the casting mold, after the inside of the molten metal nozzle has been filled with a molten metal. CONSTITUTION:Between a pair of casing molds 5, 5 formed by connecting endlessly many blocks 7, a molten metal is supplied from a molten metal nozzle 2 which has been inserted between them, and when starting a block type continuous casting machine for cooling and coagulating the molten metal by turning synchronously said casting molds 5, 5 in the direction as indicated with an arrow, a dummy bar 8 is made to abut on the tip of said molten metal nozzle 2 by interposing a heat insulating material 11. Subsequently, after the inside of the molten metal nozzle 2 has been filled with the molten metal, the dummy bar 8 and the heat insulating material 11 are moved with the casting mold in the direction as indicated with an arrow separated from the molten metal nozzle 2. In this way, a casting piece having a good quality is cast safely without developing a coagulation hull at a contact X to the casting mold 5.

摘要： PURPOSE:To prevent the generation of a defect on an ingot surface and the failure of a nozzle tip by providing a control plate on the down stream side of the nozzle tip so that a molten metal collides against the block side of a casting mold at a prescribed flow rate. CONSTITUTION:A taper having the inside diameter increasing gradually toward the tip 5a of the pouring nozzle 5 is provided to the tip and the control plate 9 is fixed near the top end 5a. The position for attaching the plate 9 is where the flow 10 of the molten metal collides against the surfaces of block molds 1, 2 near the nozzle tip. The space between the plate 9 and the tip 5a is determined at the size to provide the flow rate of the molten metal at which the growth of a solidified shell can be prohibited. The molten metal supplied from the nozzle tip 5a is changed in the direction of the flow by the plate 9 so as to collide against the surface of the molds 1, 2, thereby preventing the connection and fixing of the solidified shell 7 and the solidified shell 8 on the inside surface of the molds 1, 2. The generation of the defect on the ingot surface and the failure of the nozzle tip 5a are prevented.

摘要： PURPOSE:To improve the surface quality of a product by forming the surface layer part of a block of a refractory material and constituting the intermediate part of the block of a heat insulating material having a flow passage for cooling fluid. CONSTITUTION:The surface layer part 2 of the block 1 is formed of the thin- walled refractory material 5 and a base part 3 constituted of a cylindrical support frame 8 is disposed. The intermediate part 4 of the block is formed of the heat insulating material 6 such as ceramics at the intermediate of the surface layer part 2 and the base part 3 and flow passages 7 for cooling air are disposed in the required position thereof. Many pieces of such blocks 1 are connected by connecting pieces 9 to form an endless cooling block belt, thereby constituting an endless track type continuous and horizontal casting machine. The molten steel supplied from a tundish is prevented from being quickly cooled by the intermediate block 4 having the surface layer refractory material 5 and heat insulating material 6 of the block 1 and therefore the solidified shell grows gradually. The generation of the wave shape on the surface of a continuously cast steel plate is thus obviated and the surface quality is improved.

摘要： PURPOSE:To improve the thermal fatigue strength of a casting mold by controlling the surface temp. difference between the blocks prior to the use for the heat extraction of a continuous casting mold and the blocks after the use for the heat extraction and diminishing the fluctuation with of the thermal stress during the movement cycle of the blocks. CONSTITUTION:A molten metal supplied from a tundish 1 through a pouring nozzle 2 is cooled and solidified between casting molds 5 and 5 by which a steel ingot 6 is produced. The blocks 7 after the use for the heat extraction of the ingot 6 contacts again with the molten metal via coolers 8 and the cooled blocks 7 are heated up by heaters 9 before such blocks contact with the molten metal. The surface temp. difference between the block 7 just prior to the use for the heat extraction and the blocks 7 after the use for the heat extraction is thereby decreased. The fluctuation width of the thermal stress during the movement cycle of the casting mold blocks is thereby diminished and the thermal fatigue strength is improved.

摘要： PURPOSE:To prevent the generation of a solidified shell in a gate for the molten metal on twin-rolls in the stage of casting continuously a steel plate, etc. with a twin-roll type continuous casting machine by passing electric current to the molten steel flowing down from a tundish and applying a magnetic field to the molten metal flow. CONSTITUTION:The molten steel 5 is supplied from the tundish 3 through nozzle, 4, 4' into the molten steel pouring basin constituted of side gates 2, 2' provided on the both sides of the twin rolls 1 and the rolls 1 are rotated, by which a steel ingot 8 is produced. Magnetic field generators 7, 7' such as coils are installed alongside the gates 2, 2' to form the magnetic field. Electricity is at the same time conducted to the molten steel 5 in the tundish as the anode and the rolls 1 or the ingot 8 as the cathode, by which the molten steel flows 9, 9' from the nozzles 4, 4' are shifted toward the gates 2, 2' accoring to the Fleming's left- hand rule. The steel ingot 8 having good quality is thus produced without cooling of the molten metal in contact with the side gates and the consequent formation of the solidified shell.
