Abstract
The utility model relates to a baking device for an integrated water gap of a continuous casting tundish. The baking device comprises a cylindrical baking barrel, the inner wall and the bottom of the baking barrel are provided with fireproof material layers, two symmetric supports are welded on the outer wall of the baking barrel, the wall of the baking barrel is provided with an air duct, one end of the air duct is welded on the outer wall of the baking barrel, the other end of the air duct is welded with an exhaust pipe joint and an air blowpipe joint, and the opening end of the baking barrel is also welded with a cover plate. When the baking device is used for baking, an integrated water gap is inserted into the baking device, the combined part of the outer wall of the integrated water gap and the upper port of the baking device is tied up tightly by asbestos cloth, and then fire is lighted to bake the tundish for 1.5-2 hours, when the temperature in the tundish reaches 700-800 DEG C, a compressed air valve is opened, and compressed air is blown into the baking device through the air blowpipe joint to guide smoke in the tundish to be discharged through the exhaust pipe joint so as to bake the integrated water gap of the baking device.
Description
Technical field
The utility model relates to the metallurgy industry technical field, particularly a kind of device that the continuous casting tundish monoblock type mouth of a river is toasted.
Background technology
The arc continuous casting middle water containing opening has the two kinds of forms in the split type mouth of a river and the monoblock type mouth of a river at present, and the split type mouth of a river is made up of middle water containing opening and crystallizer submersed nozzle two parts, and the monoblock type mouth of a river is that middle water containing opening and submersed nozzle are integrated.The apparatus for baking of middle water-coating port is mainly contained two kinds of drawing-in type and suction types, and the drawing-in type apparatus for baking needs auxiliary devices such as air-introduced machine, and structure is complicated, and takies the limited working space in continuous casting tundish zone; The suction type apparatus for baking requires itself and middle water containing opening junction good seal, and needs the compressed air of elevated pressures.Two kinds of roasting modes are all because of suction force is bigger, exist the cast that produces during baking in the tundish is sucked in the mouth of a river and stops up the problem at the mouth of a river.For the split type mouth of a river, if blocked when baking, can change the crystallizer submersed nozzle, the production of assurance continuous casting is carried out smoothly.Just can not change and the monoblock type mouth of a river is blocked when baking, continuous casting production will be affected.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art and a kind of device that the continuous casting tundish monoblock type mouth of a river is toasted is provided.
The technical scheme of the utility model is: a kind of continuous casting tundish monoblock type mouth of a river apparatus for baking; It comprises the cylindrical baking bucket of a bottom lock, open upper end; Inwall and bottom at the baking bucket are provided with refractory masses, on the outer wall of baking bucket, are welded with the bearing of two symmetries.On the barrel of baking bucket, be provided with a breather line; One end of breather line is welded on the outer wall of baking bucket; And communicate with the inner chamber of baking bucket, the other end of breather line is welded with an exhaust fitting, and exhaust fitting and breather line angle are 150 to spend; The diameter of exhaust fitting is less than the diameter of breather line, and its binding site adopts arc-shaped transition.On breather line, also be welded with a gas blow pipe joint, the diameter of gas blow pipe joint is less than the diameter of exhaust fitting, and is on the same axis with exhaust fitting, and the gas blow pipe joint is connected with compressed air piping through rubber tube.Openend at the baking bucket also is welded with a cover plate, and the internal diameter of cover plate is slightly less than the internal diameter of wall circular refractory masses in the baking bucket.
The utility model is compared with middle water containing opening apparatus for baking of the prior art and is had following characteristics:
1, the continuous casting tundish monoblock type mouth of a river apparatus for baking that provides of the utility model is simple in structure, convenient and reliable operation.
2, compressed air pressure and traffic requirement are lower, and can adjust at any time according to the mouth of a river situation of toasting, and guarantee the cured effect at the mouth of a river.
3, gripper shoe rests on the slag basin of tundish baking position; When not working, tundish monoblock type mouth of a river apparatus for baking do not support the bearing on the baking bucket outer wall by gripper shoe; The bottom of baking bucket is placed in the slag basin; Make the height of whole tundish monoblock type mouth of a river apparatus for baking be lower than casting platform, do not influence the normal operation of other equipment.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.
Description of drawings
Accompanying drawing 1 is a tundish monoblock type mouth of a river baking sketch map;
Accompanying drawing 2 is a tundish monoblock type mouth of a river apparatus for baking structural representation.
The specific embodiment
A kind of continuous casting tundish monoblock type mouth of a river apparatus for baking; It comprises the cylindrical baking bucket 1-1 of a bottom lock, open upper end; Inwall and bottom at baking bucket 1-1 are provided with refractory masses 1-6, on the outer wall of baking bucket 1-1, are welded with the bearing 1-7 of two symmetries.On the barrel of baking bucket 1-1, be provided with a breather line 1-3; The end of breather line 1-3 is welded on the outer wall of baking bucket 1-1; And communicate with the inner chamber of baking bucket 1-1, the other end of breather line 1-3 is welded with an exhaust fitting 1-4, and exhaust fitting 1-4 and breather line 1-3 angle are 150 to spend; The diameter of exhaust fitting 1-4 is less than the diameter of breather line 1-3, and its binding site adopts arc-shaped transition.On breather line 1-3, also be welded with a gas blow pipe joint 1-5, the diameter of gas blow pipe joint 1-5 is less than the diameter of exhaust fitting 1-4, and is on the same axis with exhaust fitting 1-4, and gas blow pipe joint 1-5 is connected with compressed air piping through rubber tube.Openend at baking bucket 1-1 also is welded with a cover plate 1-2, and the internal diameter of cover plate 1-2 is slightly less than the internal diameter of wall circular refractory masses 1-6 in the baking bucket 1-1.
