PCT No. PCT/SE90/00339 Sec. 371 Date Nov. 19, 1991 Sec. 102(e) Date Nov. 19, 1991 PCT Filed May 22, 1990 PCT Pub. No. WO90/15160 PCT Pub. Date Dec. 13, 1990.An arrangement for use when treating a melt, particularly a metal melt (2) in a converter (1) with gas, for the purpose of intensifying and rendering effective the contact between gas and melt and to produce effective admixture of the gas with the melt. The arrangement includes at least one nozzle (5) which discharges into the melt (2) and which is operative to deliver the gas in the form of at least one high pressure jet. For the purpose of producing a high gas pressure of such value as to produce a finely-divided mixture of gas and melt in a jet zone (10) in the melt (2), a pressure-elevating device (9) is incorporated in the fluid line connected to the nozzle (5). The invention also relates to a method of treating a metal melt in a converter. |
