IN SITU REFRACTORIES USED IN THE CONTAINMENT OF MOLTEN IRON AND STEEL; STRATEGIES FOR THEIR DEVELOPMENT

In situ refractories are defined as brick or unshaped products, which react internally or with furnace atmospheres and/or slag components so as to be enhanced in their performance. Examples of such products are discussed with emphasis on those that are currently employed and are being developed for the melting of iron and steel. Some strategies for the development of future in situ products are outlined.
