Description
Technical field
The utility model relates to a kind of recuperative heater furnace wall burner block, belongs to heater for rolling steel equipment technical field.
Background technology
Recuperative heater is the visual plant of hot rolling line.At present, heating furnace furnace wall burner block be mullite pouring material carry out in advance pre-formed after, furnace wall build or ramming time install fixing in advance to prefabricated burner block, then build or ramming furnace wall time and furnace wall formed one form heating furnace burner.The structure of existing burner block is two vertical side spray mouths, and even not to billet heating temperature in use, the intensity of side spray mouth on burner block that length is larger simultaneously also has impact.In addition because burner block spare part is bulky, conduct oneself with dignity about 2.3 tons, when changing burner block, cause constructional difficulties the narrow and small sky of furnace interior is little, integral replacing burner block needs to remove intact furnace wall also will cause waste.Therefore, be necessary to improve the structure of existing burner block, and take new installation method.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of recuperative heater furnace wall burner block, and this burner block heating is more even, and the intensity of burner block is enhanced, simultaneously easier for installation.
The technical scheme solved the problems of the technologies described above is:
A kind of recuperative heater furnace wall burner block, it has four circular spouts, four circular spouts are that two rows are arranged in parallel in burner block plane, upper row is parallel with the top and bottom of burner block respectively at the line of centres of burner block plane with two circular spouts of lower row, two circular spouts of upper row and lower row the same side the line of centres of burner block plane and the two sides of burner block parallel, the central axis of two circular spouts of upper row and lower row the same side is laterally inclined respectively to the burner block of homonymy at horizontal plane.
Above-mentioned recuperative heater furnace wall burner block, the horizontal cross-section of the supporter between the circular spout in described both sides is trapezoid platform.
Above-mentioned recuperative heater furnace wall burner block, the central axis of the circular spout in described both sides is at the two sides inclination 15-25 degree of horizontal plane respectively to burner block.
The beneficial effects of the utility model are:
The utility model is under the prerequisite keeping former burner block appearance and size constant, and two of former burner block sleeve configuration spouts are changed into four circular spouts tilted to both sides, burner flame intensity improves, and steel temperature uniformity improves.Inner support body between the circular spout in both sides is slope trapezium structure, improves the stability of burner block, enhances the intensity of burner block, extend its service life.
The utility model adopts cast-in-place method to make, and solving large-scale burner block scene cannot an integral replacing difficult problem, and avoids destroying intact furnace wall, and solving knows clearly all removes furnace wall because burner block damages, again build a difficult problem.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 1.
In figure, mark is as follows: burner block 1, circular spout 2, supporter 3.
Detailed description of the invention
The utility model redesigns transformation under the prerequisite keeping former burner block appearance and size constant, changes two of former burner block sleeve configuration spouts into four circular spouts 2.
Show in figure, four circular spouts 2 are that two rows are arranged in parallel in burner block 1 plane, upper row is parallel with the top and bottom of burner block 1 respectively at the line of centres of burner block 1 plane with two circular spouts 2 of lower row, and upper row is parallel with the two sides of burner block 1 at the line of centres of burner block 1 plane with two circular spouts 2 of lower row the same side.
Show in figure, circular spout 2 is Ramp jets, and the central axis of two circular spouts 2 of upper row and lower row the same side is laterally inclined respectively to the burner block 1 of homonymy at horizontal plane, and angle of inclination is 15-25 degree.
Show in figure, because circular spout 2 tilts to both sides, the horizontal cross-section of the supporter 3 between the circular spout 2 in both sides is trapezoid platform structure, enhances burner block bulk strength, extends service life.
After adopting the utility model, furnace wall need not be removed and carry out brickwork wall again, not only can save and heavily build expense, the gas consumption because burner problem causes can be reduced again.
After this transformation is implemented, furnace wall situation returns to new stove level, and burner flame intensity improves, and steel temperature uniformity improves, and this transformation simultaneously can save the resistance to material of furnace wall at least 300 tons, significantly reduces maintenance cost.
An embodiment of the present utility model is as follows:
The diameter of the circular spout 2 of upper row is 241mm; The diameter of the circular spout 2 of lower row is 253mm; The central axis of circular spout 2 is 21 ° respectively to the angle of inclination of both sides; Burner block 1 material is phosphoric acid quick-drying anti-explosion castable.
Use procedure of the present utility model is as follows:
According to design drawing, use timber to make burner block cast in situs mould in advance to the burner block damaged, use pneumatic pick scene thoroughly to remove the residual body of burner block, afterwards by clean for scene cleaning, on-the-spot formwork, mould front and back end timber is closed, in case leak-stopping material, upper heating burner block and furnace roof side wall intersection are got through to build, lower heating burner block reserves at upper end formwork and builds angle, cast in situs, removes mould after 12 hours, with heating furnace maintenance normal ignition baker, put into production after 3 days.
On-the-spot formwork is utilized to use aluminium silicate fiber containing zirconia felt to serve as dilatation joint, phosphoric acid quick-drying anti-explosion castable is used to build, to reach the same effect of burner block with prefabricated rear installation in advance, fixation is played to heat storage in heat storage tank, by demand for heat, Combustion flame height, length is improved.
The symmetrical burner angle of on-the-spot space gas and upper-lower position adjustment is tackled during formwork, often pair of burner angle coincide point should be greater than heating furnace center line, and require that coal gas burner spray orifice height should at the outside 150mm of the air burner spray orifice of correspondence, air is wrapped up, to reduce oxidization burning loss to meet whole burning for coal gas.The control accurately to burner flame length and flame height can be reached by burner adjustment, thus reduce flame directly on localized hyperthermia's impact of heating slab, and effectively reduce slab head and tail temperature difference.
The burner block to damaging is needed thoroughly to clear up, clean before installation.Using high-temp glue mash to smear evenly with furnace wall contact surface, use the thick aluminium silicate fiber containing zirconia felt of 20mm to paste, carry out formwork subsequently, die top reserves pouring basin.
