摘要： A composition of flake graphite, binder clay and a refractory material is extruded from an auger machine into a mold to form a cylindrical graphitic casting nozzle brick. The mold includes a coaxial core terminating short of an extrusion die of the auger machine, so that the graphitic casting nozzle brick as extruded has a longitudinal bore with one end closed, with transverse holes being subsequently defined through the nozzle brick across the bore adjacent to the closed end. As an alternative, a coaxial core may be connected to an extrusion screw of the auger machine to define an axial through bore in the casting nozzle brick as the latter is extruded.

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.
