PURPOSE:To produce a titled device which permits easy adjustement of the variance in sheet layers through adjustment of presurizing and can produce broad metallic sheets with uniform thickness by forming a molten metal injection part into plural small chambers that can be pressurized respectively independently. CONSTITUTION:A molten metal injection part 19 is constituted of outside walls 9 and plural small chambers 13 partitioning the spacing therebetween with partition plates 12. Filters 5 are provided to the lower parts of the respective chambers 13, and pressurizing ports 4 are formed rspectively to the top ends. Hence, it is possible to exert different pressures respectively indepenently to the chambers 13. In producing metallic sheets with the metallic sheet producing device provided with such injection part 10, for example, when the sheet thicknesses in both end parts in the axial direction decrease, the pressures there are made higher than those in the other part, whereby the rates of supply of molten metal 2 in both end parts are increased and the sheet thicknesses are thus corrected. |
