摘要： PURPOSE:To suppress the waving of a pouring basin and to produce a steel plate having good quality by applying horizontally a magnetic field to the surface of the surface of the pouring basin in a continuous casting machine and conducting electricity thereto in the horizontal direction and the direction intersecting orthogonally with the magnetic field. CONSTITUTION:This continuous casting machine produces the steel plate 5 by storing the molten steel 3 supplied from a nozzle 6 to form the pouring basin 8 above a pair of cooling rolls 1, 2 disposed to face each other apart at a prescribed spacing, rotating the rolls 1, 2 to move the solidified layer of the molten steel 3 formed atop the same and casting the steel plate. The magnetic field is formed forward and backward in the horizontal direction to the surface part of the above-mentioned pouring basin 8 by coils 7 provided before and behind the same and the electricity is conducted between a pair of electrodes 9 and 10 provided on the right and left in the direction intersecting orthogonally therewith to generate the electromagnetic force in the pouring basin 8 from above to below. The waving of the surface of the basin 8 is thus dissipated and the generation of defects such as double skins and cracks of the steel plate 5 is prevented.

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.

摘要： PURPOSE:To dry the condensed water generated on the surface of cooling bodies and to produce continuously and safely an ingot having excellent quality by injecting dried air or inert gas to the outside circumferential surface of the cooling bodies prior to the start of casting. CONSTITUTION:Gas blowing nozzles 4 are provided in proximity to one end edge each of a pair of the cooling rolls 1 which rotate i opposite directions in proximity to each other on the outside opposite from the proximate parts. The nozzles 4 are disposed to parallel or incline with the axial line of the rolls 1 and to have about 0-85 deg. angle with the cooling surfaces. The rolls 1 are rotated while the inert gas is infected from the nozzles 4 toward the outside circumferential surfaces of a pair of the rolls 1 to blow away the water on the surfaces until a molten metal 3 in a vessel 2 arrives at the rolls 1. The continuous production of the ingot having the excellent quality is thus made possible.

摘要： PURPOSE:To prevent generation of a solidified shell at the bottom end of an end mold and to improve the quality of a product by providing a molten metal pool preventive part constructed to project increasingly toward a bottom mold in the casting direction of a steel plate to the inside surface of an end mold. CONSTITUTION:The outermost flowing part of the molten metal 5 flows from the upper part on the inside surface of the end mold toward the lower part when the molten metal 5 is poured from a supply nozzle 4 into a gate. The molten metal flows along the curve of the molten metal pool preventive part 8 in the lower part in this state. The generation of exfoliation in the flow of the molten metal 5 is thus obviated and therefore the generation of a solidified shell owing to the molten metal pool is prevented.

摘要： PURPOSE:To prevent steam explosion and to assure the safety of operation by heating the moisture sticking to the surface of the molds (cooling blocks with an endless track type and twin rolls with a twin roll type) of a continuous casting machine so that the steam is vaporized until the moisture arrives at the inlet for a molten steel. CONSTITUTION:The surface temp. of the blocks 1 of the endless track type continuous casting machine, etc. is detected by a thermometer and the temp. and flow rate of the cooling medium to be passed in the blocks 1 are properly controlled in accordance with the result of the detection with the thermometer to maintain the surface temp. of the blocks at the b. p. of water or below. The moisture 8 sticking to the surface of the block 1 is thus vaporized by heat in the midway of moving to the pouring side of the molten steel 5 by which the surface of the blocks 1 is thoroughly dried. The evaporation of the moisture is also possible when a hot wind dryer, etc. are disposed on the outside of the blocks to apply heat from the outside. The above-mentioned method is also similarly executable as a mold drying method of twin roll type and various other continuous casting machines.

摘要： PURPOSE:To prevent surely water-vapor explosion, due to the moisture condensation on the surface of a cooling body, by previously heating a vessel and the cooling body up to a desired temperature, in continuously casting a slab by bringing a molten metal in the vessel into contact with the cooling body, to quench and solidify the molten metal. CONSTITUTION:The inner surface of a vessel 2 is preheated by combustion gas by using a burner before starting casting, and cooling rolls 1 are also heated at the same time by passing hot water through the insides of rolls 1. The temperature of rolls 1 at that time, that is the temperature of the outer circumferential surfaces of rolls 1 is required to be not less than the dew point of the water vapor in the combustion gas. For instance, a partial pressure of water vapor is 0.7atm, when C gas, consisting of 55%H2, 30% CH4, 8% CO, 3% C2H4, 2% CO2, 2% N2, is perfectly burned by O2 only; and the water temperature, corresponding to a saturated steam pressure equal to this partial pressure, is 90 deg.C, that is a dew point.
