REFRACTORIES FOR BLAST FURNACE AND AUXILIARY AGGREGATES
1. Refractory materials for blast furnace We offer to examine blast furnace hearth lining made according to new layout in comparison to ordinary linings made earlier. Laying of small-pieces graphitized carbonaceous products is performed tightly to blast furnace stave (cooling bed) in order to transmit heat from combined carbon-bearing products to blast furnace stave well-timed. To seal gaps between graphitized products and carbonaceous blocks with carbonaceous filling mix. Considering that carbonaceous filling mix moves inside the blast furnace, it allows to gather maximum strength and reach planned thermal conductivity figures. Modification of blast furnace hearth construction increased hearth wall thermal conductivity effect. And isotherm 1100С moves inside the blast furnace, that creates good conditions for wall accretion forming on the surface of blast furnace lining. This construction allows to protect refractories from hot-metal and slag penetration, to prevent oxidation on the surface of combined carbon-bearing products that significantly increases lifetime of blast furnace hearth and hearth bottom.

2. Casthouse materials Magnezit Group offers and supplies refractories for casthause of blast furnace (main runners, iron and slag runners, tilting runners). When all recommendations are followed the guaranteed life of the linings can be for main runners (before capital repair): more than 3 million tons of cast iron for working lining of main runners (with intermediate repairs); more than 200 thousand tons of cast iron for working lining of iron and slag runners (with intermediate repairs); more than 250 thousand tons of cast iron for lining of covers (more than 12 months). The rate of use of mixes for main runners is from 0.16 to 0.25 kg of refractory castable per ton of cast iron.
