In non-ferrousNon-ferrous metal furnaces the installed magnesiaMagnesia -chromite Chromite refractoryRefractory lining is exposed to several stresses, rather complex in their interaction. Therefore, a detailed investigation and understanding of wear mechanisms through "post mortem studies" is an important prerequisite for refractoryRefractory producer. Additionally, in order to determine the most suitable refractoryRefractory products and to improve the lining life of refractories, practical corrosionCorrosion testingTesting with processing slags is performed. For this purpose the test-facilities, such as induction furnaceFurnace , rotary kiln but also cup test and drip slagSlag test, allow the best possible understanding of chemothermal brick wear on pilot scale. Prior to testingTesting a complete mineralogical investigation, thermo-chemicalThermo-chemical calculation via FactSageTM of the slagSlag was carried out. Based on such research results, combined with specific process knowledge RHI Magnesita can recommend appropriate brick lining solutions for non-ferrousNon-ferrous metal furnaces.
