Abstract
The invention provides a non-water-cooling end wall structure of a thermal treatment furnace at medium-low temperature. The non-water-cooling end wall structure comprises an internal furnace thermal end face, a furnace surface cold end face and heat preservation materials arranged between the two end faces. The furnace surface cold end face is mainly composed of an outer wall plate, an outer wall reinforcing plate, a surface sealing plate, a sealing frame plate and a bent sealing plate in a double-layer splicing mode. The outer wall plate, the outer wall reinforcing plate, the surface sealing plate, the sealing frame plate and the bent sealing plate are of a partitioning structure. The double-layer plates are manually staggered in partitioning position so as to reduce leakage of furnace gas. According to the non-water-cooling end wall structure, completeness and good sealing of the end wall structure are guaranteed, cooling water using amount of the thermal treatment furnace is reduced due to elimination of cooling water, energy is saved, and furnace thermal efficiency is improved.

Technical field
The present invention relates to a kind of Non-water-cooled end wall structure, be applicable to the end wall structure on all kinds of heat-treatment furnaces of non-ferrous metals processing industry, be particularly suitable for heating furnace, soaking pit and the annealing furnace of aluminium, belong to " F27D: more than one the general stove of stove; kiln, the parts of oven or retort or annex " technical field in International Patent Classification (IPC).
Background technology
Along with the progress of heat power engineering, all kinds of heat-treatment furnaces of aluminium are to energy-efficient direction development, and the thermal efficiency, the minimizing energy resource consumption that improve stove are to realize the essential condition of producing the high production capacity of ton product, low energy consumption, assurance product quality.The headwall of stove is the necessary component of batch-type furnace or passing-type furnace.The quality of end wall structure has determined the temperature homogeneity that product heats in stove to a great extent, and also remote-effects the energy consumption of ton product.
Under prior art condition, for middle Low Temperature Heat Treatment stove, general fire door opening size is larger, and firedoor frame self intensity and thermal deformation are at high temperature the emphasis that each engineering project is paid close attention to.For preventing high temperature deformation, firedoor frame is equipped with water collar around, but the existence due to water collar, the furnace gas temperature at stove headwall position is lower, for making up this familiar lacunas, the method that user just takes to vacate the method for stove gate material level or additionally increases the thermic load concurrent heating of stove gate position makes up, and the former is because having influence on production production capacity, user can only increase input again and build standbyly, and the latter has had influence on user's product competitiveness in the market because of the raising of ton product energy consumption.
For this reason, the water-cooled of cancellation stove headwall is technical problem anxious to be studied and that solve.
Summary of the invention
In view of this, the object of this invention is to provide a kind of Non-water-cooled end wall structure of novel heat-treatment furnace, be intended to effectively improve temperature homogeneity in stove, prevent thermal deformation, reduce ton product energy consumption, improve the production efficiency of stove.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of Non-water-cooled end wall structure of heat-treatment furnace, comprise burner hearth hot junction face, stove skin cold junction face and be arranged on the insulation material between its both ends of the surface, this stove skin cold junction face is mainly by Side fascia, exterior wall gusset plate, face seal plate, sealing frame board and bending sealing plate form, wherein: described Side fascia, exterior wall gusset plate, face seal plate, sealing frame board and bending sealing plate are all fraction block structure, the place that all fraction block structures have a dilatation joint all in bottom or the outside sealing plate that adopts one-sided fixing, opposite side is free-ended seal form, this exterior wall gusset plate one end and the continuous air-tightness welding of Side fascia one side, the other end is fixedly connected with face seal plate, between two-ply, being provided with sealing gasket seals, sealing frame board one end and face seal plate link together, and be provided with sealing gasket and seal between two-ply, and the other end is fixedly connected with bending sealing plate.
Preferably, the Non-water-cooled end wall structure of above-mentioned heat-treatment furnace, wherein: described exterior wall gusset plate welding one side is fixedly connected with the position that is associated of stove by gusset; Face seal plate is fixedly connected with by connecting bolt with exterior wall gusset plate, sealing frame board respectively; Sealing frame board and bending sealing plate link together by pin.
Again preferably, the Non-water-cooled end wall structure of above-mentioned heat-treatment furnace, wherein: described exterior wall gusset plate is consistent with sealing frame board piecemeal position dimension, and staggers with face seal plate piecemeal position dimension; Bending sealing plate piecemeal position dimension is consistent with face seal plate.
Technique effect of the present invention is mainly reflected in: the partitioned organization that the stove skin cold junction face of original monoblock type headwall steel plate structure is split into the two superimposed being spliced to form by a plurality of fraction block structure parts bilayers, for material reserves the space of free wxpansion under hot, fully discharge the thermal stress of hot lower metal material, and structurally by the piecemeal position people of doubling plate for staggering, to reduce the leakage of furnace gas.Non-water-cooled end wall structure of the present invention guaranteed end wall structure integrality and and fire door between excellent sealing, cancelled the consumption of headwall water collar structure and cooling water, improved the temperature homogeneity of material in stove, economic benefit and social effect are very remarkable, can be widely used in all kinds of heat-treatment furnaces.
Accompanying drawing explanation
Fig. 1: the cutaway view of the Non-water-cooled headwall of heat-treatment furnace of the present invention;
Fig. 2: schematic diagram (dilatation joint place) is looked in the Non-water-cooled headwall part of heat-treatment furnace of the present invention.
In figure, the implication of each Reference numeral is: 1-stove skin cold junction face, 10-Side fascia, 11-exterior wall gusset plate, 12-face seal plate, 13-sealing frame board, 14-bending sealing plate, 2-burner hearth hot junction face, 3-fire door, 4-insulation material, 5-gusset, 6-sealing gasket, 7-sealing plate, 8-dilatation joint.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand and grasp.
As shown in Figure 1, the Non-water-cooled end wall structure of heat-treatment furnace, comprises the stove skin cold junction face 1 of the burner hearth hot junction face 2 away from fire door 3, close fire door 3 and is located at the insulation material 4 between these both ends of the surface.
Stove skin cold junction face 1 is the partitioned organization of a two superimposed, mainly Side fascia 10, exterior wall gusset plate 11, face seal plate 12, sealing frame board 13 and bending sealing plate 14, consists of.Exterior wall gusset plate 11 one end and the continuous air-tightness welding of Side fascia 10 1 side, and be fixed together by gusset 5 and stove, exterior wall gusset plate 11 other ends are fixedly connected with by connecting bolt with face seal plate 12, be provided with sealing gasket 6 and seal between two-ply; Sealing frame board 13 one end and face seal plate 12 link together by connecting bolt, add sealing gasket 6 and seal between two-ply, and the other end and bending sealing plate 14 link together by pin.
