Refractories in Heating Units

In 2005–2007 a change-over was accomplished OAO NMLK blast furnaces to the use of contemporary poured and rammed trough mixes. Results are provided for manufacturing technology, operation and repair of rammed and poured trough linings made from low and ultralow mixes of corundum-silicon carbide composition. The existing structure of troughs and casting yards for BF-2, BF-3, BF-4, and BF-6 do not permit use of refractory concrete linings, and therefore in order to line the main troughs of these furnaces ramming mixes produced by OAO Dinur and the firm Calderys are used.
