Considerable progress has been achieved in the production of low-inclusion steels as a result of the continuous further development of steelmaking technologies as well as intensive use of secondary steelmaking procedures and improvement of the continuous casting processes. The steels continue to include, however, a certain number of large oxidic inclusions, which have a negative effect during subsequent processing and lead to rejects or material failure. The problem consists in finding these macroinclusions and further reducing their percentage. For this purpose it was necessary to develop additional process engineering measures for the zone ladle, tundish, submerged nozzle, mould in order to improve the macrocleanness, and to use a suitable method of assessment therefor.
