Abstract
The present invention relates to a valve plate of hot air valve adopted for iron-smelting in blast furnace. It includes the following several portions: left and right circular side plates, fire-resisting liner, internal enclosure ring, external enclosure ring, left and right ring-shaped side plates, water inlet pipe and water outlet pipe. It is characterized by that the external enclosure plate of said valve plate adopts composite plate, said composite plate includes base material and surface material, said base material is made of low-carbon steel and the surface material is made of austenitic stainless steel. Said invention also provides the connection mode of all the above-mentioned portions and their concrete structure.
Description
Technical field
The present invention relates to the hot blast valve that a kind of blast furnace ironmaking equipment is adopted, relate in particular to a kind of hot air valve plate.
Background technology
Hot blast valve is installed on the hot blast manifold of blast-furnace hot-air furnace system, is the control Combustion of Hot Air Furnace phase and the switching device of pipeline keying on air.Hotblast stove on air, hot blast valve is opened, (0.3～0.5MPa) is sent to blast furnace by hot blast valve to all hot blasts; The Combustion of Hot Air Furnace phase, hot blast valve cuts out, at this moment hot blast valve particularly its core component valve plate to bear the huge thermal load of being responsible for a side from hot blast.The later stage seventies 20th century, for adapting to the requirement of high wind-warm syndrome, adopt way at depression position, valve plate two sides ramming refractory liner, the valve plate life-span is increased, but still can't resolve the problem of periphery ring oxidation and decarburization.Invention disclosed patent hot blast valve is high temperature resistant, and multiple element oozes technology (publication number: CN1193664A) altogether, be in the hot blast valve manufacturing process, to add the thermo-chemical treatment operation, though improved the high temperature oxidation resistance of periphery ring, complex process, cost is higher, and its application has been subjected to certain limitation.
Summary of the invention
The present invention is for solving the problems referred to above that existing hot air valve plate exists, adopt the combination valve plate technique, succeed in developing a kind of new type hot air valve in BF valve plate, improved the ability that valve plate periphery ring resistance to high temperature oxidation and heat-resisting wind wash away effectively, thereby prolonged the work-ing life of valve plate and even hot blast valve.
The present invention has adopted following technical measures:
Circle side plate and refractory liner about this hot air valve plate comprises, interior enclosure, periphery ring and left and right sides annular side plate, and water inlet pipe, rising pipe etc.About circle have water-stop sheet to be separated into water channel between the side plate, is communicated with formation internal cooling structure with the water annulus that interior enclosure, periphery ring, left and right sides annular side plate and water-stop sheet constitute, interior enclosure is provided with water-in and water outlet.Described valve plate periphery ring adopts composition board, and composition board is divided base material and lining, and base material is a soft steel, and lining is an austenitic stainless steel, and interior base material and outer facing material are combined as a whole, and form outer resistance to high temperature oxidation and heat-resisting wind erosional layer.
Described periphery ring and about two-layer fillet weld is arranged between two annular side plate, internal layer is the soft steel weld seam of weldering periphery ring base material, outer austenitic stainless steel weld joint for weldering periphery ring lining.
Between the circle side plate supporting pin is set about described.
Be equipped with the anchor nails of reinforcing usefulness on the circle side plate about described refractory liner inboard.
This hot air valve plate periphery ring is owing to adopt soft steel-austenite stainless steel composite board, lining austenitic stainless steel resistance to high temperature oxidation, and heat-resisting wind scouring capability increases substantially, inner in addition water-cooled, thereby prolonged valve plate work-ing life greatly, according to statistics, improved 8 times than original valve plate life-span.

Embodiment
Introduce embodiments of the invention below in conjunction with accompanying drawing.
This hot air valve plate mainly by about circle side plate (1) and refractory liner (2), interior enclosure (7), periphery ring (dividing base material (9) and lining (10)) and left and right sides annular side plate (8), and water inlet pipe (11) and rising pipe compositions such as (12).About have water-stop sheet (3) (4) to be separated into water channel between circle side plate (1), the water annulus that constitutes with interior enclosure (7), periphery ring, left and right sides annular side plate (8) and water-stop sheet (13) (16) is communicated with, be provided with supporting pin (5) between the circle side plate (1) about the former, enclosure (7) is provided with water-in (14) and water outlet (15) in the latter, can be communicated with the water channel of the two thus.Be equipped with the anchor nails (6) of reinforcing usefulness about refractory liner (2) inboard on the circle side plate (1).
The valve plate periphery ring adopts 20 steel-0Cr18Ni9Ti composition board, and base material (9) is 20 steel, and lining (10) is 0Cr18Ni9Ti.Between base material (9) and the lining (10) is one in conjunction with the explosibility fusion.Periphery ring and about have two-layer fillet welding boxing to meet between two annular side plate (8), adopt mild steel electrode during weldering internal layer base material (9), adopt austenite stainless steel-made welding rod during weldering outer shell fabric (10).
Claims (5)
1. the hot air valve plate that adopts of a blast furnace ironmaking, circle side plate and refractory liner about comprising, interior enclosure, periphery ring and left and right sides annular side plate, and water inlet pipe and rising pipe, about circle have water-stop sheet to be separated into water channel between the side plate, and be communicated with water annulus that interior enclosure, periphery ring, left and right sides annular side plate and water-stop sheet constitute, interior enclosure is provided with water-in and water outlet, it is characterized in that: described valve plate periphery ring adopts composition board, composition board is divided base material and lining, base material is a soft steel, and lining is an austenitic stainless steel, and interior base material and outer facing material are combined as a whole.
2. hot air valve plate according to claim 1 is characterized in that: described periphery ring base material soft steel and lining austenitic stainless steel are blast fusion one.
