Refractory Linings in the Iron and Steel Industry

STEULER-KCH is the specialist when it comes to innovative refractory lining concepts in the iron and steel industry. We have customised solutions on hand for all types of units that operate using the Midrex, Energiron/HYL and Corex direct reduction process. Whether they are being used in air and process gas heaters, in reformers, or in the heart of the plant (the shaft furnace itself), our materials and refractory systems are precisely tailored to the requirements of our customers in the iron and steel industry.

STEULER-KCH supplies a complete range of refractory materials for lining blast furnaces. Our materials, based on fireclay, andalusite, SiAlON-bonded corundum and SiC, can be found in every imaginable section of the blast furnace, from the shaft neck to the hearth.

Our fired and resin-bonded andalusite, bauxite and corundum materials can be reliably installed as the permanent and wear linings of torpedo and pig iron ladles used for transporting pig iron.

High-quality refractory materials with a reaction-bonded mullite matrix and free SiO2 content of less than 1.5 % are a prerequisite for the casting of high-quality steel using the ingot casting method. For this, we recommend using our B 80 UG/UGT material.

The high temperature fired corundum grade KE 92 UG/UGT, with reaction-bonded mullite matrix and a free SiO2 content of under 0.5 %, is suitable for manufacturing the highest quality steels and for the extended casting times involved in producing large ingot sizes. These highly specialised refractory materials prevent casting channel expansion and alumina inclusions and ensure that our discerning customers achieve the required quality of production.

Our many years of experience and the continual refinement of our established products and services speak for themselves – STEULER-KCH offers individually tailored refractory solutions for demanding applications in the iron and steel industry. Always at the forefront of our minds: our customers' desire to optimise the long-term availability and efficiency of their plants and component systems.
