Abstract

The advantages of replacing of rammed castables by vibration-placed castables as the material for fabricating the lining of blast-furnace runners are considered. Batches of environmentally safe vibration-placed castables commercially available from Dinur JSC bauxite-based HCBSs, modified with finely disperse quartz glass, are used as the binder. The castables were tested at the Nizhny Tagil Metal-and-Steel Works. Endurance of the castable under operating conditions of the main runner is 140 thousand tons of iron (to first repair) and greater than 1 million tons (to overhall). The overall consumption rate of the castable is 0.25 – 0.35 kg/ton iron and 0.10 – 0.15 kg/ton iron (in routine repair conditions), which is substantially higher in comparison with the traditionally used rammed castables. At present, 80% of the total number of operating blast-furnace runners at the NTMSW have a lining made of vibration-placed castables.
