Oxygen-lime distributor for steelmaking vessel |
摘要 |
Excessive wear is eliminated in a distributor utilized in a bottom-blown oxygen steelmaking converter for distributing oxygen and entrained lime to the converter tuyeres by the provision of a spiral ramp that extends between the inlet and outlet regions of the affected portion of the distributor. The ramp is arranged to mechanically separate the entering oxygen-lime mixture from that flowing through the affected region thereby preventing the interference between the two flows and the wear-producing flow acceleration attendant therewith.
