Steel is here homogenised, additionally alloyed to the exact chemical composition, heated to the appropriate casting temperature and desulphurized, and modification of inclusions is performed using filled profiles. After this out-of-furnace processing molten steel is sequentially cast on three continuous casters into billets, slabs or small slabs. All assortment of steel and concast slabs and billets meet requirements of EN ISO 9001:2000, the plant has been long time certified acc.
