Purpose of the present invention also can realize in the following way:
The described zirconium material slip coating 3 that is arranged on outside the float glass furnace tank block 1 is that zirconium white 50-68%, silicon oxide 30-40%, aluminum oxide 1.0-1.8% are arranged, and the preparation of ferric oxide surplus forms through 1400 ℃ of high-temperature firings.
Described full-enclosed insculating method for wall of float glass furnace, it is characterized in that: be arranged on zirconium material slip coating 3 outer continous way thermal insulation layers 2 and be followed successively by light weight fireclay brick, asbestos powder 4, fixation steel plate 5, and by integral body of jackscrew 6 fixing formation, continous way thermal insulation layer 2 also can adopt other high temperature materials to be made.
Described full-enclosed insculating method for wall of float glass furnace is characterized in that: the continous way thermal insulation layer 2 that is provided with outside zirconium material slip coating 3 is constructed when heating-up furnace is warming up to 1200 ℃.
Full-enclosed insculating method for wall of float glass furnace of the present invention, main inventive point is that one deck zirconium material slip coating 3 is set outside kiln tank block 1, continous way is set promptly without any the thermal insulation layer 2 in slit outside zirconium material slip coating 3, the kiln pool wall is formed the method for Totally enclosed heat-preserving, this method is to utilize standard rule small weapon brick, adopts laid dry to puzzle pool wall.Slit and grey iron block at first are provided with zirconium material slip coating 50mm outward, slip coating external application angle steel forms framework, in forming framework, angle steel uses the brick thermal insulation layer of the thick soft clay of 230mm, the thick asbestos bisque of 45mm is set outside the brick thermal insulation layer of soft clay, reinforce the 4mm steel plate in the external application of asbestos bisque, make continous way Totally enclosed heat-preserving pool wall, because the pool wall grey iron block need not adopt special large size grey iron block, each contact plane is the same with usual way, greatly reduce the cost of pool wall, slit and grey iron block at first are provided with zirconium material slip coating outward, and slip coating is provided with the continous way thickening outward and reinforces thermal insulation layer.
Fig. 1 is a prior art separate type heat insulation layer structure synoptic diagram;
Fig. 2 is a prior art separate type heat insulation layer structure side schematic view;
Fig. 3 is the heat insulation layer structure side schematic view of full-enclosed insculating method for wall of float glass furnace of the present invention.
Fig. 3 is the most preferred embodiment of full-enclosed insculating method for wall of float glass furnace of the present invention, below in conjunction with accompanying drawing full-enclosed insculating method for wall of float glass furnace of the present invention is described in further detail: as Figure 1-3: 1 tank block, 2 continous way thermal insulation layers, 3 zirconium material slip coatings, 4 asbestos powders, 5 steel plates, 6 jackscrews, the float glass furnace pool wall structure of making as shown in Figure 3, realized float glass furnace pool wall reinforcement Totally enclosed heat-preserving, making processes is as follows: pool wall adopts laid dry, each contact plane is the same with usual way, but requires brickwork joint the smaller the better as far as possible.From inside and outside two sides with mud gun special zirconium matter mud is squeezed into brickwork joint before the heating-up furnace, and careful filleting, adopt to burn empty kiln method and allow its sintering, this pug is through 1100-1300 ℃ of high temperature sintering, form a kind of high high-viscosity glass body of zirconium composition that contains with the glass metal reaction of infiltrating brickwork joint in the surface mass of tank block 1 and the kiln, do not trickle, as long as the outside has the object that stops slightly, just can avoid the seepage of glass metal in the kiln, solve the technical barrier of glass metal seepage in the kiln preferably.Thermal insulation layer construction will ℃ be carried out later at heating-up furnace to 1200, is followed successively by outside the pool wall grey iron block: the thick special zirconium material of (1) coated 50mm; (2) build the thick light weight fireclay brick of 230mm; (3) the thick asbestos powder of coated 45mm; (4) fix with the 4mm Plate Steel, paste the angle steel of ∠ 40 * 40 * 4mm in the vertical position welding of pool wall face, spacing 250mm forms cavity, and to insert asbestos powder, the angle steel of ∠ 100 * 100 * 10 in the horizontal welding of the outside, jackscrew peak on the angle steel fixing.Float glass furnace of the present invention is made and is finished.Full-enclosed insculating method for wall of float glass furnace of the present invention, be to realize by above-mentioned improvement to kiln pool wall insulation construction, this scheme has solved and should be incubated, do not influenced again the expansion issues of tank block, also solved glass metal to the pool wall erosion problem: principle is that subsurface erosion mainly is a brickwork joint, brickwork joint comprises two kinds of perps and flush joints again, has cancelled flush joint at present abroad, adopts the method for soldier course, China also has flush joint, adopts two-layer or multi-ply construction.To the erosion of perps from two transverse convections, the one, the convection current of liquid pool middle part and limit portion, this is because there are temperature difference institute in middle part and limit portion extremely, keeps under the certain fluidity at glass metal, and both temperature difference are big more, convection current is strong more, and after the pool wall enforcement insulation,, all reduce this kind convection current no matter be which kind of guarantor's method, is continous way and strengthen the Totally enclosed heat-preserving method because of thermal insulation layer, therefore will weaken this convection current without any the slit biglyyer.Second convection current is the top-down motion of glass liquid layer of being close to pool wall, its end is dissolved in first convection current, this convection current is owing to be close to pool wall, so it plays crucial effects to the erosion of perps, the power of this convection current is from being close to pool wall glass liquid layer different heights up and down, i.e. differing temps.Make whole pool wall inner face upper and lower temperature difference trend consistent and strengthen the Totally enclosed heat-preserving method, naturally just reduce this convection current, and the separate type insulation, should not be incubated on the immobilising brickwork joint, form upper and lower temperature difference, cause brickwork joint vertically flow to strengthen, thereby the aggravation brickwork joint corrode, the result that this contrast experiment who is us by a large amount of kilns observes.Full-enclosed insculating method for wall of float glass furnace of the present invention has solved past people and has thought brickwork joint is protected, and can aggravate erosive prejudice.Little, the high insulating effect of heat radiation, energy-conservation, kiln long service life have been realized.
