The Drive for Greener Steel Steelmakers accepted the challenge: to reduce energy losses and CO2 emissions in steel production. The refractory linings of transport and treatment vessels such as steel vessels are crucial in meeting sustainability targets. Our raw material innovations enable a new design of refractories to accompany you in this journey to success. … Weiterlesen …
Ratingen (Germany) and Huntingdon, Tennessee (USA) – INTOCAST AG announced in March the construction of a new, state-of-the-art production manufacture of MgO-C refractories and materials specifically for the American market. For over 45 years, INTOCAST has been a recognized expert in refractories, the essential materials that helps shape the steel industry. The Tennessee plant is … Weiterlesen …
Innovative ideas and technologies represent, on a more holistic level, a contribution to a self-sufficient, resource-efficient implementation of the company’s own raw materials with reference to new applications of the Eisenberger Luting Sand with its fractionable and defined finest grain fractions in micrometre and sub-micrometre scales. Above all, mineral raw materials such as Eisenberger Luting … Weiterlesen …
Due to their excellent thermomechanical properties and corrosion resistance against aggressive steel/slag systems, carbon-bonded magnesia (MgO–C), alumina-magnesia (AMC), and magnesia-alumina (MAC) bricks are the dominating refractories for the lining of the side walls and bottom of steel ladles, basic oxygen furnaces, and electric arc furnaces.
The terms of “high performance” and “high cost-effectiveness” for refractories are so familiar. However, to answer questions like what the real meaning of high performance is, how to represent it, what the evaluation criterion is and how to realize high performance and meanwhile high cost-effectiveness seems to be not that easy without thinking in depth.
Although the suppliers and developers of refractories often know what is expected of their product, in many cases the details of what requirement is how important are unknown and difficult to estimate.
Transport properties of refractory materials are required to predict the infiltration behavior in contact with corrosive species.
Carbon bonded magnesia and magnesia-alumina bricks are used in the side walls and bottom of steel ladles for more than 30 years.
The temperature dependence of the thermal conductivity of refractory products is calculated from the linear course between the logarithms of the thermal conductivity and the logarithms of the temperature in Kelvin.
This article details the use of Life Cycle Analysis (LCA) methodology as applied to refractory materials and in particular to calcium aluminate cements.
