Description
Technical field:
The fuel gas tunnel kiln that is used for foamed glass foaming belongs to the production unit of multicellular glass production field.
Background technology:
At present, the foamed glass foaming kiln owner will adopt pushed bat kiln structure formation both at home and abroad, can be referring in the Chinese patent 02215445.0, its type of drive is typical sliding friction transmission, friction resistance is bigger, material and structural requirement to guide rail and slideway are higher, both easily deform under hot environment, influence the transmission effect greatly, also choking phenomenon can occur sometimes, have to stop the kiln maintenance, slide rail and slideway are big because of abrasion loss, need after using for 6～December, change, greatly influence and industrially normally carry out, and production cost is improved.Therefore, be limited to the weakness that this kind adds the heating kiln transmission mode, its foaming kiln length generally only has 20～26 meters, be difficult to prolong foaming kiln length, improve industrial scale, its major cause and adds in the heating kiln and generally can only pass through a row foam glass product, only promising 5000～7000 cubic metres of the year output of foamed glass blank due to the influence of friction resistance and thermal distortion.Therefore, such multicellular glass adds the development that heating kiln has limited the multicellular glass production scale.Such foamed glass foaming kiln does not have stable section, and does not more have corresponding heating and control device, and being difficult to make, the blank of foamed settles out.
At present, most foaming kilns of producing heat insulation-type (unicellular structure) multicellular glass all are to adopt electric energy as heating energy source, and electric energy is as secondary energy, and its cost is higher relatively.Producing multicellular glass adopts the major cause of electric energy to be to produce heat insulation-type (unicellular structure) multicellular glass employing charcoal element as whipping agent, in general the charcoal element is beginning to take place oxidizing reaction more than 450 ℃, and it is not softening at this temperature lower-glass body, if oxygen concentration is excessive in adding heating kiln, will make the charcoal element that oxidizing reaction takes place in advance, therefore can cause the multicellular glass admixtion to be difficult to foaming, can not form vesicular structure, in order to overcome the influence of oxidizing atmosphere in the foaming kiln, mainly adopt electric energy as heating source all the time, electric energy can ensure that kiln atmosphere is in neutral atmosphere or weak oxide atmosphere, reduces the problem of oxidation in advance of multicellular glass admixtion.
At present, foam glass product production mainly adopts the high temperature steel metal die as the multicellular glass thermal formation apparatus, general multicellular glass admixtion forms the vesicular foam in the time of 800～900 ℃, the high temperature steel mould can deform behind long duration of action under this temperature condition, in order to reduce the distortion of mould, generally die size is controlled in the smaller size range, the general die size that is adopted is L * B * H=450～550 * 400～450 * 150～180mm, because the distortion of mould can make the foamed glass blank of producing have irregular profile, such blank can reduce the material rate of cutting of foamed glass blank because of irregular profile when forming foam glass product through cut mechanically.
Glass powder is mixed with whipping agent and various auxiliary agent, and through the heat of preheating section preheating and foaming section, glass powder is heated to form molten state, and the whipping agent generation gas that reacts makes the inner foaming of vitreum and expand to form multicellular glass.The cooling section of the tunnel furnace structure of ordinary construction is because the hyperthermia radiation of the section of being foamed, the influence of thermal conduction and kiln car accumulation of heat, the multicellular glass that has foamed is after entering cooling section, it is very slow to lower the temperature, even run to kiln tail exit to foamed glass blank, though the multicellular glass shell hardens, but the core temperature of foamed glass blank still has 700～800 ℃, vitreum still is in soft state, when the blank after the demoulding enters annealing furnace annealing like this, produce be full of cracks because of the solidified duricrust is softening again, and shrink along producing on the thickness direction, shrink size and reach 20～30%, and it is oblate that the interior pore shape of multicellular glass is become, and causes apparent density, ultimate compression strength, degradations such as thermal conductivity.In Chinese patent 02215445.0, adopted a kind of improved cooling structure mode, the foaming section and the kiln top portion of cooling section joining place to be removed, its length has 0.4～1.0 meter long, effectively furnace heat is released by its open space.
