Semifinished continuously cast steel products represent the optimum solution for raw materials for hot-rolling sectors in that they present low costs and satisfactory quality. It should be observed though that, sometimes, longitudinal fissures appear on the surface of these semifinished products. The paper presents the results of material investigations undertaken at A.M. Hunedoara, using discs taken from continuously cast blooms on faulty areas. The research has evidenced three technological risk factors in practice, these being the thermal regime in the distributor, the inadequacy of the crystalizer cooling diagram and the Alsol/Altot in liquid steel brought for smelting.
