Current modernisation of the production process at Ilyich Iron and Steel Works involved modernisation of the continuous casting machine (CCM-2). The whole repair cost is around EUR 120,000. The unit has been subject to planned renovation and implementation of new technologies makes it possible to increase the overhaul period twofold.
Corrosion-resistant support structures, extended roll rigidity and amendments to the water decontamination system for cooling hot steel were implemented to improve the reliability of the CCM and increase the overhaul period. The repair involved replacement of worn parts, modernisation of some parts, inspection and repair of mechanical, electrical and power equipment. New technologies were used for fine adjustment of the gears and axes of the unit, where all measurements were made using an electronic tacheometer.
The CCM No 2 was put into operation in 1993 and its production capacity is over 3500t of slab ingots of high quality per day. With the project annual capacity of 750,000t, the unit’s production rate has been increased to over 1Mt.
