Abstract
The invention discloses a valve plate of a hot-blast valve, wherein, the symmetrical surfaces of the outer layer of a valve plate body all adopt a layered refractory liner cover layer, the cover layer includes a heat-insulating layer, a heat preservation layer, a thermal-protective layer, a high temperature-resisting layer and an energy-saving reflective layer distributed sequentially, the heat-insulating layer adopts siliceous coating materials, the heat preservation layer adopts refractory felts, the thermal-protective layer adopts light casting materials, the high temperature-resisting refractory layer adopts heavy casting materials, and the energy-saving reflective layer adopts aluminum-zirconium high-temperature coating materials. The valve plate of the hot-blast valve obviously improves the cooling effects at both sides of the valve plate, and adopts the more advanced heat-resisting material liner structurally to improve the heat preservation and heat insulation effects and reduce the thermal load of a steel structure when comparing with the valve plate of the general liner hot-blast valve or the valve plate of the micro-water energy-saving hot-blast valve disclosed in CN1769501, and the valve plate can bear rather big thermal shock and thermal fluctuation, and will not be damaged when being started frequently, thereby extending the service life of the whole hot-blast valve.
Description
Technical field
The present invention relates to a kind of hot blast valve of blast-furnace hot-air pipe applications, particularly a kind of hot air valve plate.
Background technology
Chinese patent CN1769501 discloses a kind of energy-saving hot blast valve using little water, and the valve plate of this hot blast valve is compared with conventional lining hot air valve plate, and the large section spiral channel of lining hot air valve plate is changed at the inner water cooled pipeline of laying of valve plate body, and it is obvious to save water coolant.But save water coolant and mean the reduction cooling intensity, the thermal load that reduces cooling intensity valve plate body will increase, for the thermal load of keeping the valve plate body does not increase, its valve plate volume surrounding symmetrical surface all adopts refractory liner tectum by different level, and this tectum comprises thermal insulation layer, thermofin and high temperature resistance layer.But three layers of anti-material insulation, effect of heat insulation are limited, and surperficial heat resistanceheat resistant wind scouring capability is low, adopts the heat-resisting wind scouring effect of heavy mould material high temperature resistance flame retardant coating poor, in urgent need to be improved in addition.
Summary of the invention
The anti-material of above-mentioned hot air valve plate is incubated in order to solve, effect of heat insulation is poor, heat resistanceheat resistant wind scouring capability low technical problem in surface intends improving the valve board structure design, structurally adopts more advanced anti-high hot material lining, improve work-ing life, thereby new a kind of new hot air valve plate is provided.
The present invention solves the technical scheme that the prior art problem adopted:
This hot air valve plate comprises the valve plate body, described valve plate volume surrounding symmetrical surface all adopts refractory liner tectum by different level, this tectum comprises thermal insulation layer, thermal insulation layer, thermofin, high temperature resistance layer and the energy-conservation reflecting layer that distributes successively, thermal insulation layer adopts siliceous coating, thermal insulation layer adopts refractory felt, thermofin adopts lightening casting material, and the high temperature resistance flame retardant coating adopts the heavy mould material, and aluminium zirconium matter high-temperature coatings is adopted in energy-conservation reflecting layer.
Described valve plate body two sides perisporium welding anchor nails.
This hot air valve plate has obviously improved valve plate both sides cooling performance, compare with conventional lining hot air valve plate or the disclosed micro-water energy-conserving hot air valve plate of CN1769501, structurally adopt more advanced anti-high hot material lining, improve insulation, effect of heat insulation, reduce the steel construction thermal load, can bear big thermal shocking and heat fluctuation, frequent starting is unlikely impaired, and the hot blast valve bulk life time improves.
