DEVELOPMENT OF A MONOLITHIC REFRACTORY USING SPENT REFRACTORIES

摘要

By expanding the recycling of spent refractories, the durability of the refractories is reduced in general. In order to prevent a reduction of durability, we developed a monolithic refractory which selected the appropriate particle size distribution and selected a spent refractory with high corrosion resistance against steel making slag. In addition, by cooling the refractory, it was possible to improve the durability compared to conventional products. The result of applying these monolithic refractories to the snorkel was that campaign life improved.
