PURPOSE: To assure the sealing of a molten steel by constituting side dams of refractories and metal, projecting the refractories to a molten steel side and positioning the bottom ends thereof upper than the narrowest part between drums.
CONSTITUTION: The side dams are constituted of cooling plates 7, 7' consisting of the refractories 6, 6' and metallic members. The refractories 6, 6' are disposed by being recessed by a size (m) to the molten steel pool side from the barrel end faces of the drums. The bottom ends of the refractories are positioned upper by h1 from the line A-A passing the narrowest part between both drums so as to exist near the rolling start point of the solidified shell. The exertion of the force by the press contact of the solidified shell to the side refractories 6, 6' is obviated by such mechanism and the cooling plates 7, 7' release said load via springs 9, 9' of pressing devices to back plates 8, 8'. The wear of the refractories 6, 6' is thus prevented and the molten steel is surely sealed.
