Abstract
The utility model provides a complex structure of an arched cover for an aluminum smelting furnace, which is composed for an annular water-cooled jacket, a supporting beam for a ring skewback, light mullite pouring materials, a refractory fibre knit blanket, and refractory fibre casting materials, wherein, the annular water-cooled jacket is arranged at the outer end of a furnace cover, the supporting beam for the ring skewback which is used for supporting the furnace cover is arranged the lower end in the annular water-cooled jacket, the light mullite pouring materials, the refractory fibre knit blanket, and the ordinary refractory fibre casting materials are respectively arranged on the supporting beam for the ring skewback in sequence. The utility model has the advantages of light weight, stable structure, high temperature resistance, and long service life.
Description
The utility model belongs to the improvement of parts in the molten aluminium stove, and particularly a kind of operating temperature that is used for is 1250 ℃ a molten aluminium chimney arch shape bell composite construction.
Before the utility model, the bell that uses in the molten aluminium stove mostly is refractory brick and light-weight insulating brick is built by laying bricks or stones, causes bell weight big, and the lifting load is big, and the brick-building art complexity is long in time limit, the fuel consumption height, and service life is short.
Though occurred the folding block structured bell of molten aluminium stove refractory fibre in recent years, the molten aluminium stove bell of refractory fibre folded piece and spray fiber composite construction, though the lightness of bell makes moderate progress, but, cause service life short defective to improve all because of its project organization and use material unreasonable.
The purpose of this utility model aim to provide a kind of molten aluminium stove bell by multi-layer compound structure be combined into one in light weight, Stability Analysis of Structures, high temperature resistant, the light-duty molten aluminium chimney arch shape bell composite construction of long service life, not enough to overcome in the prior art.
The purpose of this utility model realizes with following technical scheme:
A kind of novel molten aluminium chimney arch shape bell composite construction, it has annular water collar, annular arch springing joist, light mullite pouring material, fire-resistant fiber knit blanket and common refractory fibre pouring material to constitute, the annular water collar is located at the bell outer end, the lower end is provided with the annular arch springing joist that supports bell in annular water collar, on annular arch springing joist, comply with the cold light mullite pouring material that is equipped with respectively, fire-resistant fiber knit blanket and common refractory fibre pouring material leave on mullite pouring material in addition in length and breadth to the grid-like dilatation joint of equidistant one-tenth.
Its thickness of above-mentioned light mullite pouring material is 150-200MM.
Its thickness of above-mentioned fire-resistant fiber knit blanket is 20-40MM.
Above-mentioned its thickness of common refractory fibre pouring material is 80-100MM.
Characteristics of the present utility model are: construction is simple, and overall structure is stable, and good heat insulating has prolonged service life greatly, has reduced energy resource consumption.
Below in conjunction with drawings and Examples in detail the utility model is described in detail;
Accompanying drawing 1 structural representation of the present utility model;
Accompanying drawing 2 A of the present utility model are to schematic diagram;
1 ring-like water collar among the figure, 2 annular arch springing joists, 3 light mullite pouring materials, 4 fire-resistant fiber knit blankets, 5 refractory fibre pouring materials, 6 dilatation joints.
Embodiment: the molten aluminium stove bell with a φ 6500MM is an example.
Make annular arch springing joist 2 and annular water collar 1 by designing requirement, annular water collar 1 is loaded on the bell outer end, annular arch springing joist 2 is equipped with in the lower end in annular water collar 1, to give the arch Die and mould plate of making earlier by the design size requirement is installed on the annular arch springing joist 2, giving the good thick 15MM of laying on the Die and mould plate of making earlier in addition, in length and breadth to spacing 1500MM, plate hight 150MM, grid-like wood lath dilatation joint.At first the thick light mullite pouring material 3 of cast one deck 200MM is made firm by ramming solid on Die and mould plate, then at the thick fire-resistant fiber knit blanket 4 of last tiling 40MM, the last thick common refractory fibre pouring material 5 of one deck 100MM, the floating bell upper surface on needle punched blanket 4 surfaces, poured into a mould again.Make moulding through baking.
Annular water collar 1 interior logical recirculated water cooling round arch pin joist 2 above-mentioned in the use prevents distortion, and annular arch springing joist 2 is used for bearing the weight of bell and the horizontal component of composite construction; Light mullite pouring material has high temperature resistant, flame resistant airflow scouring, unit weight 1.5T/M
3Fire-resistant fiber knit blanket unit weight≤200KG/M
3, below the thermal conductivity factor 0.13W/M.K, good heat insulating; Refractory fibre pouring material unit weight 800KG/m
3, thermal conductivity factor 0.16-0.18W/M.K can use below 1050 ℃ for a long time, and the higher temperature line that the dilatation joint 6 of design can effectively compensate mullite lightening casting material 3 expands.
The utility model can reach energy savings, the remarkable result that increases the service life.
