PURPOSE:To generate the transverse flow in a molten metal supply section so as to uniformly form a solidified shell layer and to prevent the clogging in a molten metal inlet part by installing linear motor type electromagnetic stirrers in rolls for rotating twin belts or chill blocks. CONSTITUTION:The two endless belts 21, 22 are respectively tensed by rolls 23, 24 and 25, 26 and are rotated. On the other hand, side chill blocks long in a drawing out direction are disposed to the side faces in the space between both belts 21, 22. A flat casting mold is constituted of the belts 21, 22 and the side chill blocks 27. The linear motor type electromagnetic stirrers 41, 42 are respectively mounted in the two upper and lower rolls 23, 24 on the inlet side of a continuous casting machine. The transverse flow is thereby generated in the molten metal supply section, by which the nonuniform molten steel in the inlet part of the casting mold and in a nozzle is prevented. |
