Description
Technical field
The utility model relates to the titanium slag electric furnace field of smelting, relates in particular to a kind of titanium slag electric furnace and smelts oxygen lance joint.
Background technique
Smelt the oxygen lance joint that blows stove eye usefulness open of using at titanium slag electric furnace and comprise oxygen connection and long tube, the two welds together.About the very long general 20m of long tube, be welded by the multistage pipe.Long tube stretches in the electric furnace, and furnace high-temperature can make long tube slowly melt, and causes curtailment, therefore often needs the upper new extension spray lance of in time welding.Find in operating process, when the welding extension spray lance, when welding, do not cause easily the problems such as weldering is discontented, burnt hole because long tube obtains cooling, have very large potential safety hazard, and weld interval is also long.
The model utility content
The technical problems to be solved in the utility model is: a kind of electric furnace smelting oxygen lance joint that does not need the Site Welding spreading is provided.
For the technological scheme that addresses the above problem employing is: titanium slag electric furnace is smelted oxygen lance joint and is comprised oxygen connection and long tube, and oxygen connection and long tube vertically removable seal are connected.
Further be: titanium slag electric furnace is smelted oxygen lance joint and is comprised permanent joint, oxygen connection comprises oxygen output tube, oxygen output tube inserts long tube, oxygen output tube outer surface diameter and long tube inner surface diameter coupling, be provided with seal ring between oxygen connection and long tube, permanent joint is connected with oxygen connection, and permanent joint and long tube removably connect.
Further be: be provided with the seal ring surface of contact on the oxygen connection, the seal ring surface of contact is perpendicular to the oxygen connection axis and be arranged at the oxygen output tube end; Seal ring is arranged between seal ring surface of contact and the long tube end face, the sealed circle surface of contact of seal ring and the compression of long tube end face.
Further be: permanent joint is tubulose, is enclosed within oxygen connection and long tube outside; Permanent joint one end is threaded with oxygen connection, and the permanent joint the other end is provided with Cock screw/bolt, and Cock screw/bolt radially holds out against long tube.
The beneficial effects of the utility model are: oxygen connection and long tube removably connect, when needing the welding extension spray lance, will pull down with short long tube, and the complete long tube of another root that changes the outfit, whole process time is short, does not delay smelting.Wait until the rear welding of cooling extension spray lance with short long tube, be beneficial to the assurance welding quality and shorten weld interval.Two long tubes are used alternatingly.
Description of drawings
Fig. 1 is that titanium slag electric furnace is smelted the oxygen lance joint structural drawing.
Be labeled as among the figure: oxygen connection 1, permanent joint 2, Cock screw/bolt 3, long tube 4, oxygen output tube 5, seal ring 6, seal ring surface of contact 7, oxygen hose 8.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
In order to provide a kind of titanium slag electric furnace that does not need the Site Welding spreading to smelt oxygen lance joint, titanium slag electric furnace is smelted oxygen lance joint and is comprised oxygen connection 1 and long tube 4, and oxygen connection 1 and long tube 4 vertically removable seal are connected.Oxygen connection 1 is used for connecting oxygen hose 8, and then connects oxygen cylinder.
The mode that oxygen connection 1 and long tube 4 removably connect has multiple, and for example oxygen connection 1 and long tube 4 are threaded, and prevents that in order to guarantee sealing oxygen leakage, screw thread from can be fine thread or pipe thread.This practical optimal way is: titanium slag electric furnace is smelted oxygen lance joint and is comprised permanent joint 2, oxygen connection 1 comprises oxygen output tube 5, oxygen output tube 5 inserts long tube 4, oxygen output tube 5 outer surface diameter and long tube 4 inner surface diameter coupling, 4 of oxygen connection 1 and long tubes are provided with seal ring 6, permanent joint 2 is connected with oxygen connection 1, and permanent joint 2 removably connects with long tube 4.It is can not the gap too large that oxygen output tube 5 outer surfaces and long tube 4 inner surface diameter coupling refers to that oxygen output tube 5 inserts behind the long tubes 4, causes rocking the excessive sealing effect that affects 4 of oxygen output tube 5 and long tubes.The purpose that permanent joint 2 is connected with oxygen connection 1 and permanent joint 2 and long tube 4 removably connect is to prevent oxygen connection 1 and 4 generation relative displacements vertically of long tube.
The set-up mode of seal ring 6 can be at oxygen output tube 5 outer surfaces seal groove to be set, and seal ring 6 is positioned in the seal groove, and long tube 4 internal surfaces contact sealing with seal ring; This mode shortcoming is that long tube internal surface degree of finish is had relatively high expectations, and long tube is thinner, and internal surface processing is difficult.The utility model optimal way is: be provided with seal ring surface of contact 7 on the oxygen connection 1, seal ring surface of contact 7 is perpendicular to oxygen connection 1 axis and be arranged at oxygen output tube 5 ends; Seal ring 6 is arranged between seal ring surface of contact 7 and long tube 4 end faces, seal ring 6 sealed circle surface of contact 7 and the compression of long tube 4 end faces.This mode just requires long tube 4 end finishs, and it is simple that processing long tube 4 end faces are processed long tube 4 internal surfaces relatively.
Permanent joint 2 is connected with oxygen connection 1 and permanent joint 2 can have multiple with the mode that long tube 4 removably connects.The utility model optimal way is.Permanent joint 2 is tubulose, is enclosed within oxygen connection 1 and long tube 4 outsides; Permanent joint 2 one ends are threaded with oxygen connection 1, and permanent joint 2 the other ends are provided with Cock screw/bolt 3, and Cock screw/bolt 3 radially holds out against long tube 4.The advantage that Cock screw/bolt 3 radially holds out against long tube 4 is to need not long tube 4 is done any processing.
