溶銑予備処理用 Al₂O₃-SiC-C 質れんがの開発

抄録

In the past about five years, superduty fireclay or high alumina brick has been applied for torpedo car. Recently, in accordance with the progress of desulphurization and desiliconization of pig iron in torpedo car, its lining material comes into a problem awaiting the solution. Several kinds of brick were developed for this purpose, and tested in laboratory and practically. As a result of these tests, unburned Al₂O₃-SiC-C brick was excellent in resistance to corrosion, spalling, slag penetration and oxidation. The properties and application for torpedo car of this brick are reported in this paper.
