Abstract
The utility model discloses a suspended precast block and one-piece casting combined furnace top construction. The suspended precast block and one-piece casting combined furnace top construction comprises a plurality of suspended precast blocks which are suspended on a crossbeam at the furnace top of a heating furnace, wherein an expansion gap is spaced between the adjacent suspended precast blocks; refractory fiber cotton is filled in the expansion gap, and the upward side of the expansion gap is sealed by a clay brick; a light pouring material layer is arranged on the upper surfaces of the suspended precast blocks, and a ceramic fiber machine-made board layer is arranged on the upper surface of the light pouring material layer. According to the suspended precast block and one-piece casting combined top construction, the structure continues the advantages of the conventional one-piece casting, the stress of the furnace top is uniform, the sealing effect of the furnace top is enhanced, the hot loss is reduced, occurrence of partial peeling or collapse accidents of the furnace top is completely removed, and the cost is saved for a factory.
Description
Technical field
The utility model relates to a kind of top construction of hanging prefabricated section and one-piece casting combination.
Background technology
Heating furnace heating is the important operation of steel rolling, and the operating efficiency of heating furnace directly has influence on the year steel output of factory.The pith that heating furnace furnace roof is built by laying bricks or stones as body of heater, under the environment of long term high temperature and temperature frequent variations, be easy to burst apart and high-temerature creep, in order to overcome these dangerous matter sources, the furnace roof of heating furnace generally adopts hanging form at present, and hanging furnace top adopts castable refractory and anchoring to turn, and by the hanging parts that arrange on furnace roof crossbeam, connects, furnace roof is a whole large panel structure, has good heat-insulating property.
But the furnace roof of one-piece casting, the requirement of site operation is very high, and difficulty is also large, needs formwork in on-the-spot stove, and in the baker stage, keep the long low-temperature setting stage, has strengthened the construction period of heating furnace.Due to structure as a whole, in casting process, the density of each several part there are differences, and under long term high temperature, swell increment is inhomogeneous, in use often occurs that furnace roof partly comes off or the accident of total collapse.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of top construction of hanging prefabricated section and one-piece casting combination, has solved the furnace roof problem that each several part unbalance stress peels off or caves under long term high temperature.
For achieving the above object, a kind of top construction of hanging the combination of prefabricated section and one-piece casting described in the utility model, comprises a plurality of hanging prefabricated sections that are hung on heating furnace furnace roof crossbeam, between the hanging prefabricated section between adjacent, is separated with dilatation joint; In dilatation joint, be filled with refractory fiber cotton, dilatation joint top seals with clay brick; Described hanging prefabricated section upper surface is provided with lightweight and builds the bed of material, and described lightweight is built bed of material upper surface and is provided with mechanically made ceramic fibre plate layer.
Preferably, described hanging prefabricated section is integrated and is formed by low cement pour and anchored brick; The upper end of described anchored brick is outstanding, is hung on the prefabricated section hook on heating furnace furnace roof crossbeam.
The beneficial effects of the utility model are:
1, the construction of hanging prefabricated section is simple, can by baking in advance, strengthen its hardness in general factory's batch production, guarantees that its long-distance transport does not damage, and has shortened again furnace drying time and construction period.
2, this new structure has continued the advantage of traditional one-piece casting, makes again furnace roof stressed evenly, has strengthened the sealing effectiveness of furnace roof, reduced heat loss, has thoroughly eliminated that furnace roof partly peels off or the generation of cave-in accident, for factory has saved cost.
3, this new structure long service life, easy to maintenance, maintenance cost is little, only changes the furnace roof prefabricated section damaging, and because furnace roof prefabricated section can be manufactured and baker in advance, has shortened maintenance time like this, has improved plant produced efficiency.
4, this new structure scope of application is wide, for the industries such as metal smelting furnace, fire-resistant baking furnace provide good furnace roof modular construction.
Accompanying drawing explanation
Fig. 1 is the structural representation of hanging the top construction of prefabricated section and one-piece casting combination described in the utility model embodiment;
Fig. 2 is the A-A figure of Fig. 1.
The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
As Figure 1-Figure 2, a kind of top construction of hanging prefabricated section and one-piece casting combination, comprises a plurality of hanging prefabricated sections 1 that are hung on heating furnace furnace roof crossbeam described in the utility model embodiment, between the hanging prefabricated section between adjacent, is separated with dilatation joint; In dilatation joint, be filled with refractory fiber cotton 5, clay brick 4 sealings for dilatation joint top; Described hanging prefabricated section upper surface is provided with lightweight and builds the bed of material 2, and described lightweight is built bed of material upper surface and is provided with mechanically made ceramic fibre plate layer 3.
Wherein, described hanging prefabricated section is integrated and is formed by low cement pour 7 and anchored brick 8; The upper end of described anchored brick is outstanding, is hung on the prefabricated section hook 6 on heating furnace furnace roof crossbeam.When making, method is simple, first anchored brick is distributed in mould and fixes by certain size, low cement deposit material reinject mould tamping, after it reaches certain degree of hardness, transport to oven and toast, so both guaranteed the hardness of hanging prefabricated section, shortened again the furnace drying time of heating furnace, and the batch production of Ke factory.
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
