Compositions for plugs of refractory material |
摘要 |
New compositions for refractory plugs to plug the tapholes of blast furnaces which exhibit less tendency to stiffen and to burn with the emission of heavy black smoke in use are prepared by adding 5-30 parts by weight of a petroleum pitch which has a high softening point and 10-30 parts by weight of dihydric alcohol or its polymer to 100 parts by weight of a conventional refractory aggregate composition and mixing the thus combined constituents to form a mixture.
