Abstract
The utility model discloses a kind of ladle solid steel fast sweep flame gun, interior pipe is set with in outer tube, one end of inner and outer tubes is openend, the other end of outer tube is blind end, and the centre of blind end is provided with through hole, interior pipe is threaded onto through hole, and the other end of interior pipe connects oxygen intake by the first valve, the side tube wall of outer tube near blind end place is provided with outboard tube, and outboard tube connects propane inlet by the second valve.The utility model adopts outer tube and interior pipe box assembling structure, propane combustion gas and oxygen can be passed into simultaneously, under Ladle Bottom is thoroughly located no liquid molten steel or is coated with one deck slag situation, can heat up with propane combustion gas and not stop working, guarantee that the molten steel filling end each and every one checks purging thoroughly; Do not waste molten steel, handled easily, and purge time is short can guarantee the turnover that molten steel is filled with.
Description
Technical field
The utility model relates to metallurgy industry and contains steel ware cleaning plant, is applicable to contain steel ware and clears up molten steel fast, observe, check, judges to contain the special purpose device of steel ware situation, particularly ladle solid steel fast sweep flame gun.
background technology
The molten steel liquid metal of metallurgy industry uses ladle to carry out refining and cast usually, Ladle Bottom is the important blowing device of refining thoroughly, air blowing gap is very easily covered by molten steel after casting complete, the working lining of another ladle is built by laying bricks or stones because using the resistance to materials such as magnesia, corundum, by molten steel temperatures involved, all can crack, use and to be covered by molten steel afterwards, the crackle depth cannot be checked, therefore often wears bag accident.
Current employing steel pipe leads to oxygen and cleans, due to molten steel fill with in pouring molten steel complete after, Ladle Bottom is thoroughly located no liquid molten steel or is coated with one deck slag, cannot directly purge.Reach and purge object and now can must clean by remaining molten steel in molten steel is filled with, but the waste of remaining molten steel can be produced, simultaneously steel pipe lead to oxygen cleaning requirement pour molten steel filling can not dead time more than five minutes, otherwise cannot to purge equally; Thoroughly locate to have solidified molten steel for Ladle Bottom to purge, purge after steel pipe need borrow burning torch to light and can implement melting type purging, operating process is often because purging the oversize shake of steel pipe, and lighted steel pipe and frequently stopped working, operation need restart, and finally only abandons purging.So not only waste the combustion gas that burning torch is lighted, do not reach cleaning object, be awkward, time-consuming.
Utility model content
The technical problems to be solved in the utility model is, for prior art exist problem provide one can under Ladle Bottom is thoroughly located no liquid molten steel or is coated with one deck slag situation, the handled easily that can directly purge, by the flame gun of adjustment automatically can be lighted, to realize solidifying molten steel cleaning totally in the resistance to material gap of ladle.
For achieving the above object, by the following technical solutions, ladle solid steel fast sweep flame gun, comprises outer tube and interior pipe to the utility model, interior pipe is set with in outer tube, one end of inner and outer tubes is openend, and the other end of outer tube is blind end, and the centre of blind end is provided with through hole, interior pipe is threaded onto through hole, the other end of interior pipe connects oxygen intake by the first valve, and the side tube wall of outer tube near blind end place is provided with outboard tube, and outboard tube connects propane inlet by the second valve.
Further, described inner and outer tubes are coaxial.
The utility model adopts outer tube and interior pipe box assembling structure, propane combustion gas and oxygen can be passed into simultaneously, under Ladle Bottom is thoroughly located no liquid molten steel or is coated with one deck slag situation, can heat up with propane combustion gas and not stop working, guarantee that the molten steel filling end each and every one checks purging thoroughly; Do not waste molten steel, handled easily, and purge time is short can guarantee the turnover that molten steel is filled with.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be in Fig. 1 A-A to schematic cross-section.
In figure: 1. outer tube, 2. outboard tube, pipe 3., 4. the first valve, 5. the second valve, 6. oxygen intake, 7. propane flammable gas entrance.
Detailed description of the invention
Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments, see Fig. 1 and Fig. 2, ladle solid steel fast sweep flame gun, comprise outer tube 1 and interior pipe 3, interior pipe 3 is set with in outer tube 1, one end of interior pipe 3 and outer tube 1 is openend, the other end of outer tube 1 is blind end, and the centre of blind end is provided with through hole, interior pipe 3 is threaded onto through hole, the other end of interior pipe 3 connects oxygen intake 6 by the first valve 4, and the side tube wall of outer tube 1 near blind end place is provided with outboard tube 2, and outboard tube 2 connects propane inlet 7 by the second valve 5.
Described interior pipe 3 and outer tube 1 coaxial.
The utility model ladle solid steel fast sweep flame gun (total length: 6m) is by utilizing interior pipe 3(Φ 16mm) and outer tube 1(Φ 33mm) coaxially propane (or coal gas) and oxygen mix are lighted.First valve 4 and the second valve 5 adopt ball valve, carry out the air demand and the combustion flame that control, adjust propane and oxygen.The high-temp combustion flame produced solidifies molten steel by ladle fireguard to Bao Bi and the bag end and carries out purging to clean.Carry out inspection bag condition again in order to using.
During use, the utility model ladle solid steel fast sweep flame gun is stretched into water and finish rear ladle, open second valve 5(pressure 0.3 ~ 0.5Mpa) light flame after open first valve 4(pressure 1.0 ~ 1.5Mpa), flare is adjusted to 300mm, purge covering solid-state molten steel in ladle, suitably adjust oxygen pressure according to cold steel thickness, till blowing off, usually need 2 ~ 3 minutes.
Claims (2)
1. ladle solid steel fast sweep flame gun, comprise outer tube and interior pipe, it is characterized in that, be set with interior pipe in outer tube, one end of inner and outer tubes is openend, the other end of outer tube is blind end, and the centre of blind end is provided with through hole, interior pipe is threaded onto through hole, and the other end of interior pipe connects oxygen intake by the first valve, the side tube wall of outer tube near blind end place is provided with outboard tube, and outboard tube connects propane inlet by the second valve.
