PURPOSE:To obtain a product of good rolled shape by elimination of a crack and bend and improvement in the gnawing conditions of a mill by providing plural side guiding rollers which are movable in and out between a continuous casting machine and a rolling mill on both sides of an ingot. CONSTITUTION:When the molten steel charged in a casting wheel 4 is gradually cooled as it parts from a casting port, the steel is formed to the mold shape of the wheel 4. Since the ingot shrinks in this time, cracks are generated from the corner parts. Near the outlet of the wheel 4, the ingot deforms sectionally and considerably and is cast with deviation to one side of the wheel 4. In order to prevent such deviated casting, side guiding rollers 20 devices 9 are provided at the outlet of intermediate pinch rollers 8. The roller 20 is moved by the rotation of a handle 24 to move the end face on the side of the ingot 13 deviated to its one side and the other roller 20 is spaced from an ingot 30. Generation of cracks of the ingot is prevented by this adjustment. After passage through the devices 9, the ingot 13 deviates to one side and is rolled nonuniformly with a rolling mill 17 and therefore side guiding roller devices 16 are provided and the irregular rolling is prevented by said devices, wherby the ingot is rolled to a satisfactory shape. |
