Abstract
The utility model relates to a smelting-succession furnace for a one-time molding quartz plate, comprising a furnace body; the smelting-succession furnace is characterized in that: a discharging port is arranged below the furnace body, a flash board matched with the discharging port is arranged in the furnace body, and a connecting rod is fixedly arranged on the flash board; when the smelting-succession furnace is used, the flash board can be controlled according to needs, the size of the discharging port is controlled by matching the flash board and the discharging port, so as to control the flow rate of quartz melting stock. One-time molding and one-time contraction are carried out when the quartz plate is produced, so as to reduce secondary pollution; in addition, by adopting the quartz smelting-succession furnaces with the same inner diameter, the width of the quartz plate in the utility model is more than 50 percent of that of the quartz plate which is molded for two times in the prior art, and the plate surface thickness error can be controlled within 0.3mm; the produced quartz plate has high-quality surface without air bubble lines basically, thereby achieving the S9 purity requirement and plate surface requirement of the quartz glass plate for semiconductors.
Description
Technical field
The utility model relates to a kind of quartz continuous melting furnace, particularly a kind of once shaped quartz plate production continuous induction melting furnace.
Background technology
Quartzy production of the prior art comprises body of heater with continuous induction melting furnace, is provided with discharge port and former below body of heater.During production, quartzy melt is drawn into quartz plate by the discharge port once shaped after growing up to be a useful person through the former secondary again.Its defective is: on the one hand, will shrink by secondary through post forming, the quartz plate width that the quartz continuous melting furnace of so same internal diameter is produced is less, and plate face thickness is comparatively uneven, and thickness and thinnest part differ more than the 1mm; On the other hand, post forming bubble gas line is more, also can cause secondary pollution to quartz plate by the former moulding.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provide a kind of simple and reasonable, quartz plate plate face thickness of being produced evenly, the once shaped quartz plate production continuous induction melting furnace of no bubble gas line.
Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is a kind of once shaped quartz plate production continuous induction melting furnace, comprises body of heater, is characterized in, is provided with discharge port below body of heater, also is provided with the flashboard supporting with discharge port in body of heater, is fixed with connecting rod on the flashboard.
In above-described technical solutions of the utility model, the shape of described discharge port can be the different shape that is fit to, and is preferred oval, also can be oblateness or fusiformis.
Compared with prior art, when the utility model continuous induction melting furnace uses, can control flashboard on demand, cooperating the big or small of control discharge port and then controlling the flow of quartzy molten material by flashboard and discharge port.Be once shaped when producing quartz plate, once shrink, can reduce secondary pollution, and the quartz plate width that the quartz continuous melting furnace of same internal diameter is produced is wideer more than 50% than prior art post forming, plate face thickness error can be controlled in the 0.3mm, the quartz plate plate face quality of being produced is good, substantially do not have bubble gas line, can reach the S9 purity requirement and the requirement of plate face of semi-conductor with quartz glass plate.
