The invention relates to refractory industry, namely to the compositions of refractory ramming mixtures for the production of monolithic linings of heat units with a working temperature to 1700 °С, in particular, induction hot air and crucible furnaces. The ramming mixture contains, mass %: 51-56 of corundum of 3- fraction; 4-6 of fine-grained periclase of fraction less than ; 37-41 floured alumina mixture, quartziferous additive and periclase with a size of particles, less than 63 micrometers, in ratio from 4.2:0.2:0.5 to 3.7:0.2:1; 2-3 of dry boronphosphate binder. An increased working time of heat units by means of increasing of a heat resistance and lining resistance to the action of metal fusion is provided.
Use of unfired refractory products as a lining in large-volume industrial furnaces, as well as an industrial furnace lined with said unfired refractory products.
