PURPOSE:To execute continuous casting with a small number of operators in a continuous casting installation having plural molds and two units of travelable tundish cars by providing devices which can charge continuously and mechanically ingot connecting metals to the specific positions of said cars. CONSTITUTION:The tundish cars 1, 2 which are self-travelable on rails 3 and on which the tundishes 4, 5 are respectively mounted are disposed on both sides of molds A, B in-between. The devices 6, 7 for charging the connecting metals are respectively connected to the opposed surfaces of the cars 1, 2 via base plates 8, 9 as carriages which are L-shaped when viewed from above. The car 2 is first moved onto the molds A, B and the 1st molten steel is fed into the tundish 5 from which the molten steel is poured into the molds A, B. The car 2 is moved leftward upon ending of such pouring and the device 7 is positioned onto the mold B. The car 1 is then moved so as to bring the device 6 over the mold A. The devices 6, 7 are thereupon operated to charge and detain the connecting metals (a), (b) onto the solidified shells in the molds. The cars 1, 2 are thereafter moved leftward and the 2nd molten steel is fed into the tundish 4, from which the molten steel is poured into the molds A, B. |
