Background technology
Steel plant continuous casting tundish baking adopts coal gas baking, coal gas burner that two kinds of internal-mixing and exterior mixings are generally arranged, and the gas-fired utilization rate is lower, and the thermal efficiency is generally very low, but because simple in structure, easy to use, invests lowlyer, thereby is widely used.In real work, find, be to be welded on the roaster bottom with a thick corrosion resistant plate of 3mm in the existing tundish roaster PLASTIC LAMINATED design, pipeline and valve etc. is prevented thermal protection, in use, steel plate is subjected to tundish to leak the barbecue of flame can very fast distortion, the tundish clad is owing to constantly use in addition, gap, burner place can constantly enlarge, when above roaster drops to tundish, carrying out work, have very big gap between PLASTIC LAMINATED and the tundish clad, during baking flame can from gap location between PLASTIC LAMINATED and the tundish clad a large amount of to leaking in the air, cause the coal gas baking thermal efficiency lower.Meanwhile, the baking of existing middle water containing opening changes the drawing-in type baking into by original coal gas oven baking, utilize the heat of tundish baking that the mouth of a river is toasted, though cancelled the use of mouth of a river baking coal gas, but the high-temp waste gas that injection is discharged still exists potential safety hazard to the not special improvement of site environment that the mouth of a river checks.Therefore it is very necessary existing continuous casting tundish apparatus for baking being improved.
The utility model content
Technical problem to be solved in the utility model provides a kind of continuous casting tundish apparatus for baking that can improve the thermal efficiency and improve environment, this continuous casting tundish apparatus for baking can protect roaster, sealing when increasing the tundish baking, improve the thermal efficiency, the high-temp waste gas that effluxes when simultaneously the mouth of a river being toasted is recycled, when increasing the thermal efficiency, improve environment, improve air quality.
The technical scheme that solves the problems of the technologies described above is:
Can improve the thermal efficiency and the continuous casting tundish apparatus for baking that improves environment, its roaster PLASTIC LAMINATED is made up of PLASTIC LAMINATED body and refractory coating, refractory coating is uniformly coated on the PLASTIC LAMINATED body, the upper end of PLASTIC LAMINATED hangs over the roaster bottom by hook, and the lower end of PLASTIC LAMINATED contacts with tundish clad upper surface at the mobile low level of roaster.
The above-mentioned continuous casting tundish apparatus for baking that can improve the thermal efficiency and improve environment, the thickness of the refractory coating of described PLASTIC LAMINATED is less than 100mm.
The above-mentioned continuous casting tundish apparatus for baking that can improve the thermal efficiency and improve environment, baking high-temp waste gas discharging place at middle water containing opening has increased exhaust emission pipe, the air inlet of exhaust emission pipe has compressed air inlet and high-temp waste gas import respectively, and the exhaust outlet of exhaust emission pipe is connected with the admission line of the baking arm of roaster.
The beneficial effects of the utility model are:
The utility model adopts the composite construction PLASTIC LAMINATED that refractory coating is arranged to replace the PLASTIC LAMINATED of former steel plate structure, and the fixedly connected mode of PLASTIC LAMINATED changed into can there be the activity of certain up-down adjustment amplitude to fix, when the baking arm drops on the tundish, PLASTIC LAMINATED can be automatically and the tundish clad fit, the flame that leaks when making the tundish baking drops to minimum, sealing when having increased the tundish baking has improved the thermal efficiency, has saved the consumption of coal gas.The high-temp waste gas of extracting out when simultaneously middle water containing opening being toasted is introduced the admission line repetitive cycling utilization of baking arm by exhaust emission pipe, improved the temperature of mixing air, improved efficiency of combustion indirectly, and make the whole baking system of tundish not have the extra waste gas that effluxes, improved site environment, improve air quality, reached the purpose of energy-conserving and environment-protective.
The tundish roaster of an embodiment of the present utility model is compared in actual use with originally, and tundish of baking on average can be saved gas consumption 500M3 under the constant situation of stoving time.
The utility model is simple in structure, convenience is feasible, input is not high, effect is very desirable, at continuous casting system to reducing gas consumption, reduce manufacturing cost, improving operating environment and have certain practical significance.
