<p>This application is directed to an expansible heat-retaining material of hot top surface for use in steel ingot making. A homogeneous mixture containing 1 to 30% by weight of more than one vegetable body, e.g. cereals, drained lees of sugar cane and peat moss, which have a heat expansibility is prepared in an exothermic or adiabatic composition consisting of more than one easily oxidizable metal, metal oxide, non-porous refractory materials, porous refractory material and carbonaceous materials.</p> |
