Abstract: An easily stored and used disposable cover for the opening of a molten metal type ladle is disclosed, which uses transverse ribs of green hardwood above a blanket made up of ceramic fabric batting. The ribs are tied together into an array by means of flexible wires running longitudinally across the ribs and secured to them. The ribs are sized to span across the ladle opening and to hold the blanket thereover, and the cover may be easily rolled up longitudinally so as to assume an easily stored, handled and shipped roll shape. A plurality of wide headed nails hold a sheet of plastic or like material and the blanket to the ribs. The sheet serves to protect the blanket from tearing or catching or binding together and allows it to be unrolled and handled more easily. A wire end handling loop is also provided at the longitudinal ends to aid in placing the cover over the ladle.
