Abstract

PURPOSE:To directly produce the sheet of superior quality from molten steel by cohering the molten steel on the surfaces of one set of the rolls having been internally cooled in a non-oxidizing atmosphere and compression-bonding and rolling two sheets one set of shells with the roll gap. CONSTITUTION:Molten steel is poured thrugh a nozzle 3 into the molten steel well 6 formed by twin rolls 9 of a diameter 1.5m or more and side walls 4, 8. This is so done that in a steady state the molten steel covers 1/4 or more of the peripheral length of the rolls 9. Cooling water of high velocity is flowed in the inside space 8 of the rolls 9. When the rolls 9 revolve and the molten steel makes contact with the surface 7, the molten steel deposits to form shells. The shells become gradually thicker and at the roll gap the shells on the right and left roll surfaces compression- bonded and rolled to a sheet 12. The sheet 12 is rolled by the rolling rolls 11 which are internally cooled and is then taken up. The entire process thereof is accomplished in a non-oxidizing atmosphere.
