The double heat storage heating furnace wall structure adopts fireproof heat insulation coating to carry out flame plating or daubing construction equipment, the coating can be used above 1550 DEG C to meet the highest usage temperature requirements of all kinds of steel rolling heating furnaces to achieve furnace lining inner wall insulation, and therefore working temperature and outer wall surface temperature of the fireproof materials of the heating furnace are reduced, and the purpose of reducing surface heat loss, slowing damage of the fireproof materials of the furnace wall and increasing the service life of the furnace wall is achieved.
Description
Technical field
The utility model relates to recuperative heater furnace brickwork structure, relates to specifically a kind of double heat storage type heating-furnace wall construction.
Background technology
Regenerative combustion technology is carried out flue gas waste heat recovery by the heat storage accumulation of heat, combustion medium is preheating to 800 ~ 1100 ℃, simultaneously, jet by combustion medium in combustion process, entrainment flue gas and realize High Temperature Air Combustion, significantly reduce the NOx concentration in combustion process, have the technical characterstic of not only energy-conservation but also environmental protection.China developed and used regenerative continuous heating furnace in iron and steel enterprise the nineties in 20 century, and then made the low calorie fuels of iron and steel enterprise get the efficient use and be promoted.Yet the problem of ubiquity burner badly broken in the practical application of great mass of data report recuperative heater causes that the burner surrounding is burned with anger, stove district CO concentration is higher, seriously threatens safety in production.For this reason, domestic a large amount of scientific worker has carried out recuperative heater burner Breakage Reasons and relevant improvement research thereof.As: Xiao Haidong in 2011 in " iron and steel technology " publish thesis on the 6th phase " design alternative of the Store Heat Stove of Steel Rolling type of furnace and key equipment ", the reason that this paper is burned with anger to two thermal storage heating stove furnace walls is analyzed, think that burner block is combined not tight with the furnace wall body, cause in burner coal gas of high temperature to scurry into furnace wall by the faying face gap, after furnace wall Plate Welding gap is excessive, burn in atmosphere; Its burner steel construction and the furnace wall Plate Welding is insufficient, the cast of anti-material is not tight, insulation material is selected improper etc. around burner of having its source in.publication number is that to disclose the accumulation of heat of a kind of leakproof fire be burner to the Chinese utility model patent of CN201348250Y, it provides a kind of by steel construction, castable, the gas leakage prevention heat accumulating type burner that honeycomb heat accumulation body and burner block consist of, steel construction wherein, castable and honeycomb heat accumulation body consist of burner body, burner block is positioned at the front end that burner body gos deep into heating furnace one side, its end face in stove is provided with the gas ejection ports of perforation, characteristics are that four sides of burner block are provided with one sloping platform or groove, the gradient of sloping platform is 30 °, can make and scurry between heating furnace furnace wall and burner block the flare in the gap under the stopping of sloping platform or groove, turn in stove, thereby greatly reduce the possibility that fire is leaked at this place.Yet due to performance difference between prefabricated burner block and castable, the faying face gap is difficult to contain fully, and the furnace wall risk of burning with anger still exists.For this reason, domestic scholars is from eliminating the deficiency that between burner block and castable, performance difference brings, carried out the research of heat-accumulating burner and the integrated poured forming technique of furnace wall, as: publication number is that the Chinese invention patent of CN201010613705.2 discloses a kind of heating furnace furnace wall one-piece casting construction method with heat-accumulating burner, the method first becomes the burner block internal mold with the cold-rolled steel sheet assembly welding, filling preformed hole internal mold; It is inboard that the rear intermittent weld of adjustment correction is connected to the furnace wall steel construction, and add inner support; The furnace wall formwork props up the burner block internal mold simultaneously and buries in the furnace wall template; Burner block internal mold outer wall brushing interleaving agent before matched moulds; Then build refractory material, after refractory material reached the design strength of mould stripping, furnace wall template and burner block internal mold were removed simultaneously, remove at last the preformed hole inner membrance; This invention does not need prefabricated and fixed installation burner block separately, and employing is with the mode of burner block and furnace wall while one-piece casting, reduced construction period, economical with materials consumes, installation process is more simple, and its monolithic devices and sealing are showing and improve, and avoid producing the space between burner block and furnace wall, thereby avoid due to the fiery potential safety hazard that causes of string, be particularly useful for construction period shorter heating furnace maintenance and salvaging.Liu in 2011 has accounted for just and Huang Shili has invented " transformation of prestige steel Regenerative Heating Furnace " this paper at " industrial furnace " and reported and take integrated poured mode to carry out heat-accumulating burner and furnace wall manufacture craft on the fourth phase, that is: cancel burner block, make embedded part with the stainless steel that resistance to elevated temperatures is strong, make frame-type with steel plate, in aggregates with low cement high alumina castable cast at last.Yet, for the double heat storage type heating furnace, many due to burner quantity, volume is large, between burner sky, gas passage and spout, spacing is little, especially empty, gas passage is the up and down parallel arrangement, and for ease of the integrated poured molding construction of burner and furnace wall, the general heat-resistance stainless steel that adopts in burner zone is made embedded part, cause this zone furnace wall construction intensity low, high temperature section burner zone body of wall is prone to softening cracking and the furnace wall phenomenon of burning with anger.
