摘要： PURPOSE:To produce continuously and stably a thin sheet having uniform and good quality by disposing a large diameter water cooling roll and a small diameter water cooling roll at the space equal to the thickness of the thin sheet, and stirring the molten metal by inert gas in the stage of forming solidified shells from the molten metal. CONSTITUTION:The molten metal 3 supplied from a ladle 5 into a tundish 4 is brought into contact with a large diameter water cooling roll 1 and a small diameter water cooling roll 2 disposed at the space corresponding to a desired thickness of a thin sheet to form solidified shells 9, 10. The shells 9, 10 are united to form a billet 7, which is transferred by pinch rolls 8. Inert gas is blown from an inert gas supply device 11 installed on the bottom surface of the tundish 4 into the molten metal 3 to stir the same. Therefore, the ruggedness of the shells 9, 10 is decreased, and when the shells are united to one body at the point P, a uniform thin sheet 7 is formed. The oxidation on the inside surface of the shells 9, 10 is decreased and the nonuniformity in the temp. of the metal 3 is eliminated.

摘要： PROBLEM TO BE SOLVED: To prevent the deposition of scum and to effectively remove the scum floating on the surface by arranging one pair of scum weir which is in parallel to cooling rolls in a molten metal pool part and has its tip part dipped in the molten metal and a means for sucking and removing the scum stayed in the scum weirs. SOLUTION: In a twin roll type continuous casting device, the surface flow of the poured molten metal 4 is caused from the center part of the molten metal pool part space to both sides in the cooling roll axial direction. The scum 5 floating up on the surface from the inner part of the molten metal is moved to the shaft end part of the cooling roll while being carried by this flow. When the scum moves and approaches the scum sucking hole 24, since gas flow is formed toward the sucking hole 24 with a vacuum pump, the scum 5 is moved to the inner part of the suction hole. When the scum 5 deposits on the sucking hole throat part, since the gas passage is clogged, the negative pressure is rapidly developed and spouted to the scum pool part 14, in which the cross sectional area of the gas passage becomes rapidly large, through an introducing pipe part 10 and the scum is removed before depositing.

摘要： PURPOSE:To provide a twin roll type continuous casting apparatus, in which the thermal deformation of the water cooling roll can quickly and smoothly be corrected. CONSTITUTION:The thin thickness part 1A is formed near the outer periphery in the width direction of the water cooling rolls 1 in the twin roll type continuous casting apparatus. An annular body 5 is inserted in the space part B between this thin thickness part 1A and a shaft 4. In the inner part of the annular body 6, heated water flowing groove 5a is formed. Further, in the water cooling roll 1, a water supplying passage 1b, water cooling passage 1c and drainage passage 1d are supplied. A space part is arranged between the annular body 5 and the end surface of the water cooling roll 1. The thermal deformation of the water cooling roll 1 caused by the continuous casting is corrected by transmitting the deformation of the annular body 5, which is developed by passing the heated water through the annular body 5, to the thin thickness part 1A.

摘要： PURPOSE:To keep thickness of stuck material to the constant by continuously measuring the thickness of stuck material on the free outer peripheral face of cooling drums during casting and adjusting pressing pieces, number of revolutions and pressing force of rotating brushes in the order of priority at any time according to the obtd. measured value. CONSTITUTION:To the cooling drum 1, two pieces of the rotary brushes 11 for rough grinding and one piece of the rotary brush 12 for finish grinding are set in the order as shown in the figure on the free outer peripheral face, i.e., in the range of being shown with the arrow mark S on the outer peripheral face 4 in the cooling drum 1. Further, at the P position on the free outer peripheral face 4, the thickness of stuck material on the outer peripheral face 4 in the cooling drum 1 is continuously measured with an infrared ray image pickup device 13. The measured value is outputted as an electric signal and compared with the prescribed thickness of stuck material with a comparator, and according to the compared result, using condition of the rotary brushes 11 and 12, i.e., number of pressing pieces, number of revolutions and pressing force in order of priority, are set and adjusted with a control unit. By this method, traverse cracking is prevented and also a cast strip having the prescribed thickness can be stably cast.

摘要： PURPOSE:To prevent involution of scum into solidified shell by separately submerging refractory parting plates extended to longitudinal direction of casting rolls into molten metal and arranging exothermic means to the parting plates. CONSTITUTION:Various kinds of oxides (scum) 19 are developed on the surface 9a of molten metal 9. The scum 19 is shifted toward intersectional lines A, B of the casting rolls 2, 3 and the surface 9a by molten metal flow developed with rotation of the casting rolls 2, 3, but the shift thereof is prevented with the parting plates 12, 13 and this is not involved into the solidified shells 10, 12. The parting plate is constituted with heating refractory material 15 integrally composed of exothermic means 14 and refractory casing 16, and the refractory casing 16 is changed at suitable interval. As the parting plate 12, 13 is held to high temp. with the exothermic means 14, the scum 19 is not solidified to stick. Surface characteristic of the cast strip can be improved.

摘要： PURPOSE:To directly execute continuous casting of a clad steel plate from molten metal under using a drum type slab continuous caster by dividing the space formed by side weirs pushing to the end faces of two drums into two by a partition weir and pouring molten metals having different quality for each other into two divided spaces respectively. CONSTITUTION:The partition weir 6 is arranged into the space formed by two water cooling drums 1, 1' and two side weirs 2, 2'. And, the molten metals 3, 3' stored in tundishes 4, 4' are poured into the spaces divided by the partition weir 6 through nozzles 5, 5'. The molten metals 3, 3' are cooled by contacting with surfaces of the water cooling drums 1, 1' respectively, to form solidified shells 7, 7'. And, the solidified shells 7, 7' are integrated at a neutral point P of the water cooling drums 1, 1', to cast the clad steel plate 8 having two layers.

摘要： PURPOSE:To enable easy outflow of a molten metal even if the fine holes of a tundish is small and to produce small-diameter shot by specifying the excitation conditions over the entire part of the tundish to discharge the molten metal from the fine holes in the bottom. CONSTITUTION:The tundish 1 is a vessel to store the molten metal 3 and is provided with the many fine holes 2 for discharging the molten metal 3 in the bottom thereof. The tundish 1 is installed on a stand 9 supported by compression coil springs 8 and is united to an oscillating device 10 in order to efficiently oscillate the tundish. The entire part of the tundish 1 is oscillated at 40-100Hz frequency and 0.2-1.5mm amplitude. The molten metal flow 4 emitted from the fine holes 2 is thereby oscillated and splashed and is given shearing force to form discontinuous liquid drops which solidify to some extent during the fall in air. The liquid drops solidify further to a spherical shape when the liquid dropps fall into water 6 to form the metal shot 5.
