One way to produce large-diameter quartz glass tubes is to place quartz sand raw materials into the crucible swaslet in the furnace, to minimize the crucible stoics through the lid, and to melt the molten material into a liquid. Liquids are discharged at high temperatures and then through the vents. Gas impurities and liquid impurities, radon through the lid lift, liquid into the molding machine bench molding, raw materials continuously added to the crucible, by the tractor will be quartz glass tube mother tube pulldown, so that the quartz glass tube master tube into the secondary molding machine to walk and expand, when the .520 to 0.1mm, Large diameter glass quartz tube swelled into large diameter glass quartz tube with a wall thickness of more than 5mm. Finally, the expansion of the two ends of the quartz glass tube cut off in turn, pickling, ultrasonic cleaning, annealing.
