Abstract
The utility model provides a heating furnace door comprising a frame outside the furnace door and a metal net inside the frame. The heating furnace door is characterized in that compound fiber blocks are overlaid inside the frame of the furnace door, thereby being capable of greatly reducing the whole weight of the furnace door and improving the tightness; and simultaneously, an inner lining formed by overlaying the compound fiber blocks has good high temperature stabilization and thermal insulation, thereby effectively reducing the thermal loss of the heating furnace door and the gas consumption. Two fiber blankets with different working temperatures and performances are compounded together, thereby being capable of giving full play to the performance advantages of different fiber blankets, reducing the production cost and the weight of the furnace door to the maximum limit, improving the environment around the furnace door greatly, and decreasing the labor intensity of workers; therefore, the service life of the furnace door can reach over 5 years, thereby greatly reducing the examining and maintenance costs of the heating furnace door and a transmission mechanism of the heating furnace door and improving the production rate of a furnace.
Description
Technical field
The utility model relates to a kind of fire door, and particularly a kind of Compaction of Heating Furnace Door with the fiber liner belongs to Compaction of Heating Furnace Door design and manufacturing technology field.
Background technology
The dress of existing heavy slab heating furnace, discharge method mainly go out based on the end inlet side; what this mode was brought is that fire door is bulky; Heavy Weight; make liner though adopted conventional fire-resistant light to water material feeding; but fire door weight still can not alleviate; this in addition fire door is mostly made two or more parts, and regular meeting leaks because of poor sealing performance makes furnace gas, thereby furnace thermal efficiency is greatly affected.On the other hand, because fire-resistant light waters the intensity difference of material feeding, thermal shock resistance is bad, very easily comes off in the frequent unlatching of fire door, pass closed procedure, and this has just greatly reduced the service life of fire door.Make the large-scale fire door of liner at present with lightening casting material, generally be no more than 2 years service life, all needs every year the door lining refractory material is regularly repaired, even change, and increases the maintenance cost of stove, influences ordinary production simultaneously.Moreover the open and close of this large-scale fire door must just can be finished by the transmission mechanism and the equipment of heavy type, under the operating mode of operating load weight, poor sealing performance, make it because of being in higher operating temperature fire door transmission mechanism and equipment fault be increased, another increases the stove maintenance cost.Therefore be necessary prior art is improved.
Summary of the invention
Have the Compaction of Heating Furnace Door volume now for solving, big Heavy Weight, the refractory material intensity difference, the problem that causes fire door to damage easily, the utility model provides a kind of Compaction of Heating Furnace Door.
The utility model is finished by following technical proposal: a kind of Compaction of Heating Furnace Door, comprise the framework in the fire door outside and the wire netting of framework inboard, it is characterized in that the inboard stack of furnace door frame is provided with the composite fibre piece, the liner that is constituted with the composite fibre piece by stack makes the fire door inboard have higher hear resistance, effectively alleviates fire door weight simultaneously.
The described interblock of composite fibre in twos is provided with the heat-resisting dividing plate of band through hole on it, heat-resisting dividing plate one end is fixed on the wire netting of furnace door frame inboard, and the heat-resisting rib of wearing is set in the through hole, so that the composite fibre piece is fixed on heat-resisting dividing plate both sides, thereby form the composite fibre liner that superposes by the heat-resisting rib of wearing.
Described composite fibre piece is composited by two or more different tapetum fibrosums, working face one side is resistant to elevated temperatures polycrystalline mullite fibre, non-working surface one side is a general fibre, with in the heat resistance that increases the composite fibre piece, reduces cost and weight.
The size of described heat-resisting dividing plate is less than composite fibre piece size, by the thermal expansion character of composite fibre piece, heat-resisting dividing plate is wrapped in the composite fibre piece, and is not subjected to temperatures involved in the furnace door frame inboard at fixing composite fibre piece.
Described composite fibre piece is that the polycrystalline mullite fibre blanket of 50～100mm and thickness are that to be combined into density be 180～220kg/m for the zirconium tapetum fibrosum that contains of 150～250mm by thickness
3, thickness is the composite fibre piece of 200～350mm, and the polycrystalline mullite fibre blanket contains the zirconium tapetum fibrosum as non-working surface as working face.
The utlity model has following advantage and effect: adopt such scheme, can reduce the overall weight of fire door greatly, increased sealing, the liner that is made of the composite fibre piece that superposes has excellent high-temperature stability and thermal insulation simultaneously, can effectively reduce the Compaction of Heating Furnace Door heat loss, reduce gas consumption.The tapetum fibrosum of two kinds of different operating temperature and performance is combined with each other, can give full play to the feature performance benefit of different tapetum fibrosums, reduce fire door cost of manufacture and weight to greatest extent, improve the fire door surrounding environment greatly, reduce labor strength, fire door can be reached more than 5 years service life, reduce the maintenance of Compaction of Heating Furnace Door and transmission mechanism thereof, maintenance cost greatly, improve productivity of furnace.Be a desirable Compaction of Heating Furnace Door in fact.
