Summary:In this study a new concept of the cover for installation for continuous casting of steel have been studied and discussed. The main essence in the most favourable construction includes the existing stresses and strains developed in service conditions. Instead of former cover, made with heat-resistant concrete and flat plate, the new solution introduced two factors: increased rigidity whole cover and new thermal insulation material. It is a composite refractory material, more light, plastic and more resistant for thermal shocks. In the final results, the new tundish cover confirmed in practice prolongation of the cover exploitation from 15-25 000 tones to above 90 000 tones poured steel.
