Abstract: A metallurgical furnace or vessel is provided with a refractory lining consisting of an outer layer of tamped granular ceramic material and an inner layer, which forms a protective sheathing for the outer layer and consists of bricks made of fused lime, fused dolomite, chrome magnesite, or fused magnesia. The tamped layer of ceramic material may consist of fused magnesia or stabilized zirconium oxide or alternatively of granular quartzite, corumdum, mullite or spinel. In the latter case, an intermediate layer is provided between the tamped layer and the inner brick layer to prevent reaction between the bricks and the tamped material. The intermediate layer consists of fused magnesia or stabilized zirconium oxide.
