Description
Technical field
A kind of residual iron spout of blast furnace torpedo tank car is the utility model is related to, belongs to ironmaking technical field of auxiliary equipment.
Background technology
What present large blast furnace used is all storage type tap drain, and tap drain needs the molten iron discharge in tap drain is dry when overhauling
Only, residual iron eye is equipped with the charcoal bag lower edge of tap drain, the residual molten iron in tap drain is flowed out through residual iron eye, along residual iron runner through residual iron for this
Ditch stem bar is flowed into hot-metal bottle.Traditional residual iron spout is the end of residual iron runner, is U-shaped structure；It is residual to prevent during residual iron placing
Iron is coagulated because flow is small in residual iron runner, and residual iron eye is opened with the drill bit of 80 more than ㎜, thus residual instantaneous delivery iron early period compared with
Greatly, residual iron is fallen through residual iron spout in the form of parabolical, and drop point is farther out；When residual iron discharges soon, residual iron instantaneous delivery is big
Width reduces, and directly vertically drips from stem bar, and residual molten iron drop point changes greatly, and torpedo tank car tank mouth is small, and molten iron easily occurs and falls
The serious accident on ground, therefore traditional residual iron placing uses the larger open-top ladle of bore more, and pneumatic steelmaking now is with large-scale
Torpedo tank car contains molten iron, it is therefore desirable to residual iron spout is transformed, uses the less torpedo tank car of bore to contain to facilitate
Fill residual molten iron.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of residual iron spout of blast furnace torpedo tank car, using this
Stem bar row's residual iron placing can ensure that residual molten iron drop point is fixed, and facilitate torpedo tank car to contain molten iron, prevent the serious accident of molten iron landing.
Solving the technical solution of above-mentioned technical problem is：
A kind of residual iron spout of blast furnace torpedo tank car, including stem bar stent and metal tube；Stem bar stent and residual iron runner frame
Frame is fixed, and metal tube side wall is fixed with stem bar stent front end, metal pipe axis and horizontal plane after fixing；Inner wall of metal tube is
Back taper cavity, metal tube top is circumferentially fixed arc-shaped buting iron dam, the both ends on arc-shaped buting iron dam and residual iron runner front end
Side wall fixes the residual iron runner groove to form all side seal.
A kind of residual iron spout of above-mentioned blast furnace torpedo tank car, the stem bar stent is rectangular frame, and stem bar stent is consolidated
Due to the bottom of residual iron runner frame, the front end of stem bar stent is located at same vertical plane with the front end of residual iron runner frame after fixing
On；After the metal tube is fixed with stem bar stent front end, the top of metal tube and the bottom of trench of residual iron runner are contour；In the metal tube
Portion uses refractory material laying cavity in an inverted cone；The arc-shaped buting iron dam uses refractory material laying.
A kind of residual iron spout of above-mentioned blast furnace torpedo tank car, the arc-shaped buting iron dam crest end arc diameter are more than bottom
Portion's arc diameter, bottom arc diameter match with metal pipe diameter.
Back taper cavity inside the utility model buting iron dam and metal tube forms a funnel-form stem bar, using this practicality
During new residual iron placing, residual iron flows into the inverted cone-shaped cavity of metal tube through residual iron runner level, through entering under metal tube changed course vertical current
Torpedo tank car；When residual iron instantaneous delivery is larger, the residual iron in part can still enter inverted cone-shaped cavity after the stop bounce-back on buting iron dam,
It will not overflow, prevent molten iron landing, ensure that residual iron can smoothly enter in the less torpedo tank car of bore.
The beneficial effects of the utility model are：
The utility model can ensure that residual iron smoothly enters in the less torpedo tank car of bore, thoroughly prevent the evil of molten iron landing
Property security incident, realize that torpedo tank car receives the purpose of residual molten iron, ensures the safe and orderly of ironmaking production.

Embodiment
Fig. 1~Fig. 3 shows, a kind of residual iron spout of blast furnace torpedo tank car of the utility model, including stem bar stent 1 and gold
Belong to pipe 2；Stem bar stent 1 is rectangular frame, and metal tube 2 is steel pipe；Residual iron runner frame 3 is fixed in the upper surface of stem bar stent 1
Bottom surface, the front end of stem bar stent 1 is located on same vertical plane with the front end of residual iron runner frame 3 after fixing；The outside of metal tube 2
The front end of wall and stem bar stent 1 is fixed, the axis and horizontal plane of metal tube 2 after fixing, the top of metal tube 2 and residual iron runner
6 bottom of trench is contour, and purpose is when residual iron is flowed along the residual iron runner 6 in residual iron runner frame 3, can be entirely fallen in metal tube 2；
