Abstract
A kind of continuous induction melting furnace that draws quartz glass plate, it comprises body of heater and is located at the intravital crucible of stove, between crucible and the furnace body wall thermal insulation layer is housed, crucible bottom is provided with the moulding outlet, the moulding exit is provided with former, and former upwards joins with core bar, is provided with heating unit between crucible and the thermal insulation layer, described moulding outlet is long strip shape, and the bottom shape of former is and the supporting long strip type of moulding outlet.The quartz raw material that makes continuous fusion is shaped to quartz glass plate by the adjustable slit blanking between moulding outlet and the former, adjusts to certain speed by quartz plate tractor and frequency transformer, and the quartz glass plate continuous drawing that makes moulding is a finished product.The utility model stability and high conformity, scale error is less, realizes high efficiency quartz glass plate continuous production.
Description
Technical field
The utility model relates to a kind of production unit that is used for quartz glass plate, particularly a kind of continuous induction melting furnace that draws quartz glass plate.
Background technology
The simple glass panel products that building materials industry is produced, it is the closed kiln that is built into common refractory brick, with coal is that fuel produces coal gas feeding kiln internal combustion, after the interior raw material of stove is constantly melted, by tractor traction continuous drawing sheet glass, only in 60～70%, its product only can not be applied in new and high technology industries such as semi-conductor and optical communication as building material industry usefulness to the silicone content of its sheet glass.The quartzy furnace apparatus of existing continuous smelting can only the continuous drawing silica tube, the quartz plate that present domestic industry such as semiconductor technology and optics industry use, all be to draw on the basis of Φ 20～Φ 100mm major-diameter thick-wall silica tube by continuous induction melting furnace, spread out sheet through flame fusion for the second time after the cut mechanically and finish, it is low that it produces efficient.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of continuous induction melting furnace of continuous drawing quartz glass plate.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of continuous induction melting furnace that draws quartz glass plate, it comprises body of heater and is located at the intravital crucible of stove, between crucible and the furnace body wall thermal insulation layer is housed, the crucible bottom is provided with the moulding outlet, the moulding exit is provided with former, former upwards joins with core bar, be provided with heating unit between crucible and the thermal insulation layer, be characterized in: described moulding outlet is long strip shape, and the bottom shape of former is and the supporting long strip type of moulding outlet.
The utility model is on the basis of existing continuous induction melting furnace equipment, the moulding outlet of tungsten crucible bottom and the former of core bar lower end are improved to long strip shape, the quartz raw material that makes continuous fusion is by the adjustable slit blanking between moulding outlet and the former, be shaped to quartz glass plate, adjust to certain speed by quartz plate tractor and frequency transformer, the quartz glass plate continuous drawing that makes moulding is a finished product.The utility model stability and high conformity, scale error is less, realizes high efficiency quartz glass plate continuous production.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
A kind of continuous induction melting furnace that draws quartz glass plate, it comprises body of heater 1 and the crucible 4 that is located in the body of heater 1, between crucible 4 and body of heater 1 wall thermal insulation layer 2 is housed, crucible 4 bottoms are provided with moulding outlet 7, moulding exports 7 places and is provided with former 6, and former 6 upwards joins with core bar 5, is provided with heating unit 3 between crucible 4 and the thermal insulation layer 2, described moulding outlet 7 is a long strip shape, and the bottom shape of former 6 is for to export 7 supporting long strip types with moulding.Continuous induction melting furnace is heated up continuously, and adding glass sand raw material, when temperature reaches 1900C～2200 ℃, quartz raw material has formed to melt treats the blanking moulding, in monitor procedure, by regulating the spacing between former 6 and the moulding outlet 7, make it meet the requirement of controlling quartz glass plate, in the single stage method continuous flow procedure, finally make the sheet glass that draws out reach required technological standard simultaneously by adjusting the optimum velocity that frequency transformer ensures the quartz plate tractor.
