Abstract
The utility model discloses a reinforced protective inner cover for high-temperature belts of a bell-type furnace. A tubular cylindrical cover body is arranged on the middle section of the reinforced protective inner cover; an upper opening of the tubular cylindrical cover body is connected with a top end socket; an annular hoisting device is arranged on the top end socket; a lower opening of the cover body is connected with a bottom barrel and then is connected to a bottom sealing flange; an annular sealing groove consisting of a ring plate is arranged on the flange outside the cover body; the lower portion of the sealing groove is connected with a flange-shaped ring plate cooling water tank; the cooling water tank is connected with a water inlet and a water outlet, one end of the cooling water tank is high while the other end of the cooling water tank is low, and the low end of the cooling water tank is connected with the water outlet; more than three supporting legs can be arranged under the bottom flange; guiding arms are symmetrically arranged outside the cover; the cover body is formed by connecting 1-12 tubular straight barrels; the surface of the cover body is corrugated; a straight barrel is arranged on the burner belts; and a reinforcing ribbed plate which is flush with corrugations is arranged on the inner surface of the straight barrel. Because the strength of the burner belts is increased, the strength and the heat resistance of the cover body are increased, and the service life of the bell-type furnace is prolonged.
Description
Technical field
The utility model relates to the bell furnace that cold rolled strip thermal treatment is used, the thermal zone reiforced shield inner cover of a kind of specifically bell furnace.
Background technology
Bell furnace is a kind of cold rolled strip annealing treatment equipment.Cold rolled strip through technological processs such as heating, insulation, coolings, changes the packaging assembly of steel in bell furnace, improve mechanical property, and therefore in bell furnace, heat-treating is a kind of requisite technology in the cold rolled strip steel production process.During bell furnace work, coil of strip being contained in the inner cover, is hydrogen or nitrogen and hydrogen mixture in the inner cover; With the burner heating, Heating temperature is between 800 ~ 1000 ℃, because of thermofin is arranged on the heating mantles between inner cover and heating mantles; Therefore the high temperature moment that produces is delivered on the inner cover, and burner band temperature is the highest.Existing bell furnace inner cover is mainly the annular ripple structure; But rapid heating and cooling under the heating and the state of cooling; But because of every section ripple on same plane, the heating position of burner flame on cylindrical shell is also in same planimetric position, the burner temperature that in assembling process, occurs causing because of a variety of causes in deviation and the combustion processes when burner differs; Cause burner band position Yin Wendu to differ and produce strength stress and differ, cause inner cover to be prone to produce phenomenons such as distortion, cracking at burner band position.
The inner cover cylindrical shell is because impaired in frequent temperature changing process in practice process, especially the burner band position of inner cover.Since the bell furnace complex equipments, maintenance difficult, cost is high, then must change after the inner cover cover body damages, and therefore designs a kind of advanced person's bell furnace inner cover, improves evaporation efficiency, reduces failure rate, and increasing the service life is the problem that the bell furnace planner is concerned about always.
Summary of the invention
The purpose of the utility model provides a kind ofly can prolong the work-ing life of bell furnace, the thermal zone reiforced shield inner cover of bell furnace simple in structure, stable performance.
In order to achieve the above object, the technical scheme of the utility model is: the thermal zone reiforced shield inner cover of a kind of bell furnace, its interlude are tubulose tubular cover body; Suitable for readingly be connected with the top end socket, be provided with annular lifting appliance on the end socket of top, the cover body end opening connects the bottom cylindrical shell and is connected on the bottom seals flange again; Be provided with the annular seal groove that a circle ring flat-plate constitutes above the flange outside cover body, the bottom joint flange shape ring flat-plate cooling trough of sealing groove connects intake-outlet on cooling tank; Cooling trough one end is high, an end is low; Connect water outlet at low side, flange in the bottom can be provided with the feet more than 3 down, and guide arm is symmetrical set outside the cover; It is characterized in that: described cover body is formed by connecting 1 ~ 12 section tubulose straight barrel; The cover body surface is a corrugated, is provided with one section straight tube at burner band position, and straight tube inner face is provided with the reinforcement gusset concordant with ripple.During use the thermal zone protection inner cover of bell furnace is placed on the table, and pending coil of strip is covered in the helical corrugation inner cover, ring flange and table form good sealing, begin igniting on the cover behind the outer cover, heat up, and heat-treat.The utility model is applicable to that the hydrogen nitrogen of burner band more than 1 row mixes or full-hydrogen hood-type annealing furnace.
The beneficial effect of the utility model is; Owing to strengthened the intensity at burner band position, strengthened the intensity and the thermotolerance of cover body, prolonged the work-ing life of bell furnace; Avoided because of the differ cover body that causes of frequent burner band temperature impaired; Reduced the distortion that inner cover lower part occurs easily, phenomenons such as cracking have reduced the bell furnace rate of breakdown.
