The paper was focused on search of causes of occurrence of internal and surface defects of continuously cast steel slabs. The relationships between types of defects given in literature and their occurrence in industrial practice were investigated, ensuing from preparation of the melt according to the specification of secondary metallurgy unit and equipment of the continuous casting machine. Methods leading to the analysis of causes of formation of defects at non-observation of standard of metallurgical and technological procedures are always complicated and time consuming. The paper defines occurrence of individual types of defects and possibilities, which were developed for their removal in the BOF shop with single strand slab continuous casting machine.
