High temperature alloy suspender member is fixed with heating furnace furnace roof steel construction, and the curtain wall structure is light and handy, has the disadvantage the partition wall by refractory fibre system
Into due to the souring of high temperature gas flow in heating-furnace, refractory fibre is easy to by efflorescence, so as to cause the partition wall to use the longevity
Life is not long, and the partition wall is typically pre-formed, it is necessary to frequent integral replacing, and resistant to elevated temperatures refractory fibre and high-temperature alloy hang
Suspension member is expensive, and replacement cost is higher；The profile of other water-cooled castable partition wall or Non-water-cooled refractory fibre partition wall is length
Bar shaped so that the furnace gas in burner hearth is big by the local resistance loss at partition wall position.
The content of the invention
To solve the above problems, it is an object of the invention to provide a kind of streamlined air-cooled partition wall of heating furnace furnace roof, structure letter
It is single, it is not necessary to integral prefabricated, can simultaneously be constructed with furnace roof, easy construction；Partition wall can be with local maintenance, without integral replacing, dimension
Shield low cost, long service life, local resistance loss are small.
To achieve the above object, the present invention is adopted the following technical scheme that：The streamlined air-cooled partition wall of heating furnace furnace roof, including it is resistance to
Fiery material, anchored brick, suspender member and air-cooled pipeline, are characterized in that described anchored brick and suspender member are hung in heating furnace furnace roof steel
In structure, refractory material is coated on anchored brick outside, and partition wall top sets air-cooled pipeline, perforate on air-cooled pipeline, outside partition wall
Shape is processed into streamlined.
Of the invention further to improve, described anchored brick selects the high alumina refractories of sinter molding.
Of the invention further to improve, the composition of described refractory material is identical with heating furnace furnace roof, fire resistant materials of attaching most importance to
The composite construction constituted with light heat insulation material.
It is of the invention further to improve, tied using labyrinth between the refractory material and furnace roof of described streamlined air-cooled partition wall
Structure, fills refractory fibre at gap.
Of the invention further to improve, one layer of chamotte brick is also stamped in the top of described refractory fibre.
When using, cooling wind is blown in the outside of streamlined air-cooled partition wall via the aperture on air-cooled pipeline, increases the area
The mobility of domain air-flow, reduces the temperature of partition wall outer surface, improves the service life of partition wall, improves the operation ring of heating furnace furnace roof
Border.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, anchored brick selects the high alumina refractories of sinter molding, and the resistance to compression, rupture strength under high temperature are big, and cold without water flowing
But, long service life.
2nd, the composite construction that the refractory material of partition wall is made up of heavy refractory material and light heat insulation material, working face resists
Furnace gas performance of flushing is good；The refractory material composition of partition wall is identical with furnace roof, it is not necessary to integral prefabricated, can simultaneously be constructed with furnace roof,
Easy construction, can be with local maintenance, and without integral replacing, maintenance cost is low；The refractory material for constituting partition wall is cheap, builds
It is with low cost.
3rd, sealed using labyrinth form between partition wall and furnace roof fire resisting material, refractory fibre, sealing effectiveness are filled at gap
It is good, can effectively prevent furnace high-temperature gas excessive.
4th, streamlined air-cooled partition wall sets air-cooled pipeline, and perforate on pipeline, cooling wind exists via the perforate injection on pipeline
The outside of streamlined air-cooled partition wall, increases the mobility of the regional gas stream, reduces the temperature of partition wall outer surface, improves making for partition wall
With the life-span, improve the operating environment of heating furnace furnace roof.
5th, partition wall is streamlined contour, and the furnace gas in burner hearth is small by the local resistance loss at partition wall position.
