Abstract

Increased worldwide highly competition in steel market imposes innovative measure for the steelmaker targeting cost reduction and climate-friendly steelmaking process in order to have the ability to withstand the pressure of the market. At the same time the demand for high purity and highest quality steels continues to grow from year to year, especially in the sector automotive in transportation of oil and gas, in the construction Industry and in the manufacture of heavy plate. As they allow producers to be up to the requirements while allowing expanding their product mix, new secondary metallurgical treatments have become a must additionally to standard equipment elements of steel plants modern. Most of these treatments occurs in the steel ladle increasing the pressure to ensure a reliable and as possible neutral reactor. Intelligent solutions for refractory lining ladles should integrate better adaptation to the operational process parameters and the high reliability/availability at the best cost/performance. This challenge has conducted Refratechnik to develop new concepts to overcome the frontier between shaped and unshaped materials and that’s what will be covered in this paper.
