Abstract

Blast furnace No. 1 of OAO West-Siberia Metallurgical Combine was shut down for first category major overhaul on 06.15.2007. In putting out a tender for the choice of supplier of refractories for lining the blast furnace a mandatory condition was use of a “ceramic shell” and provision of a furnace operating life of not less than 20 years. Seven companies took part in the tender for the supply of lining refractories. The major overhaul of blast furnace No. 1 was carried out in a record short time, i.e. the period from the instant of shutdown to start-up was 107 days. Shortening of the repair time was promoted by use in the hearth (including the tuyere zone) of lining previously assembled and inspected by the supplier. Use of high quality refractory materials made it possible to increase the distance between the axes of the tap-holes and blast-furnace bottom to 2.4 m.
