Abstract
The utility model discloses a continuous melting furnace for producing a large-size quartz plate. The continuous melting furnace comprises a furnace body for production, a tungsten crucible and an insulating layer, wherein the tungsten crucible is arranged inside the furnace body; the insulating layer is arranged between the tungsten crucible and the wall of the furnace body; the top of the tungsten crucible is provided with a charge pipe and a tungsten core rod protecting gas inlet; a former charge platform is arranged at the bottom of the tungsten crucible; a rectangular forming opening is formed in the middle of the charge platform; a tungsten core rod is arranged at the rectangular forming opening; a heating device is arranged outside the tungsten crucible. The continuous melting furnace has the advantages that the large-size quartz plate meets the requirements, and is good in product quality; the molten material settling time of the continuous melting furnace is prolonged; internal quality defects such as air bubbles and air lines of the formed quartz tube are reduced; the former tungsten core rod can be finely-tuned; the large-size quartz plate of which the thickness is 60mm and the width is 500mm can be directly produced.
