Abstract
The utility model belongs to field of metallurgy, relates to a kind of converter prepurging shower nozzle.The utility model comprises oxygen supplying tube, is arranged on the shower nozzle of oxygen supplying tube one end, and described shower nozzle sidewall is provided with the spray oxygen mouth be communicated with oxygen supplying tube, described shower nozzle tapered shape, and described spray oxygen mouth is that circular arc strip is arranged on the conical surface of shower nozzle; Spray oxygen mouth of the present utility model is circular arc strip, and oxygen washes away converter mouth and inboard wall of burner hearth by forming fan-shaped Oxygen Flow after the ejection of spray oxygen mouth, and make slag condensed layer even by oxygen, slagging-off efficiency significantly improves.
Description
Technical field
The utility model belongs to field of metallurgy, relates to a kind of converter prepurging shower nozzle.
Background technology
Steel-making converter, in converting process, inevitably produces splash, and the slag mixing splashings that produce in stove are discharged in stove in company with gas, and through converter mouth, because temperature declines, part slag condenses on fire door.
General cleaning condenses in the slag on converter mouth, the mode that usual employing oxygen sprays into removes the gred, burn rapidly after the slag that the Oxygen Flow that oxygen lance blow head ejects and converter mouth condense contacts, melt and flow in stove, thus reach the object of converter mouth cleaning; But existing oxygen lance blow head spray oxygen mouth mostly is hole shape, and oxygen is injected into slag condensed layer in wire after the ejection of spray oxygen mouth, and plane of action is point-like, and make slag condensed layer uneven by oxygen, slagging-off efficiency is lower.
Utility model content
The purpose of this utility model provides a kind of Oxygen Flow to spray uniform converter prepurging shower nozzle for problems of the prior art.
A kind of converter prepurging shower nozzle, comprise oxygen supplying tube, be arranged on the shower nozzle of oxygen supplying tube one end, described shower nozzle sidewall is provided with the spray oxygen mouth be communicated with oxygen supplying tube, described shower nozzle tapered shape, and described spray oxygen mouth is that circular arc strip is arranged on the conical surface of shower nozzle;
Described shower nozzle top is recessed to form tapered shunting dish towards oxygen supplying tube direction;
Between described spray oxygen mouth medullary ray and oxygen supplying tube axis angle α be 70 ° ~ 75 °, the right central angle β of described spray oxygen mouth is 100 ° ~ 110 °;
Described oxygen supplying tube outer cover is equipped with middle tube, middle tube outer cover is equipped with outer tube, form inlet conduit between described oxygen supplying tube outer wall and middle tube inwall, form outlet passage between middle tube outer wall and outer tube inwall, described inlet conduit is connected with outlet passage;
Back-up block is provided with between described oxygen supplying tube and middle tube.
The utility model has following beneficial effect:
1, because spray oxygen mouth is circular arc strip, oxygen washes away converter mouth and inboard wall of burner hearth by forming fan-shaped Oxygen Flow after the ejection of spray oxygen mouth, and make slag condensed layer even by oxygen, slagging-off efficiency significantly improves;
2, the oxygen uniform divided flows that oxygen supplying tube is carried by tapered shunting dish extremely sprays oxygen mouth, further ensures spray oxygen even;
3, spray between oxygen mouth medullary ray and oxygen supplying tube axis angle α be 70 ° ~ 75 °, the right central angle β of spray oxygen mouth is 100 ° ~ 110 °, determines suitable spray oxygen angle and spray oxygen area, promotes slagging-off efficiency further;
4, water of condensation flows between inlet conduit and outlet passage, cools outer tube and shower nozzle, and isolated steel-making converter is to the high temperature transmission of middle tube and oxygen supplying tube simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Figure 1A-A direction view.
Embodiment
A kind of converter prepurging shower nozzle as depicted in figs. 1 and 2, comprise oxygen supplying tube 1, be arranged on the shower nozzle 2 of oxygen supplying tube 1 one end, described shower nozzle 2 sidewall is provided with the spray oxygen mouth 3 be communicated with oxygen supplying tube 1, described shower nozzle 2 tapered shapes, and described spray oxygen mouth 3 is arranged on the conical surface of shower nozzle 2 in circular arc strip; Described shower nozzle 2 top is recessed to form tapered shunting dish 4 towards oxygen supplying tube 1 direction; Angle α between described spray oxygen mouth 3 medullary ray and oxygen supplying tube 1 axis is 70 ° ~ 75 °, and the right central angle β of described spray oxygen mouth 3 is 100 ° ~ 110 °; Described oxygen supplying tube 1 outer cover is equipped with middle tube 5, middle tube 5 outer cover is equipped with outer tube 6, form inlet conduit 7 between described oxygen supplying tube 1 outer wall and middle tube 5 inwall, form outlet passage 8 between middle tube 5 outer wall and outer tube 6 inwall, described inlet conduit 7 is connected with outlet passage 8; Back-up block 9 is provided with between described oxygen supplying tube 1 and middle tube 5.
During work, shower nozzle 2 of the present utility model is stretched in converter mouth or burner hearth, oxygen supplying tube 1 starts supply oxygen, oxygen extremely sprays oxygen mouth 3 by shunting disk 4 uniform divided flows after entering shower nozzle 2, form the ejection of fan-shaped Oxygen Flow and wash away converter mouth or inboard wall of burner hearth, burn rapidly after the slag uniform contact that fan-shaped Oxygen Flow and converter mouth or inboard wall of burner hearth condense, melt and flow in stove, complete slagging-off work; Water of condensation flows between inlet conduit 7 and outlet passage 8, cools jetting oxygen tube 1, and back-up block 9 pairs of middle tube 5 play and support and fixing effect.
