[0011] The specific technical solutions of the present invention will be further described below with reference to the accompanying drawings, so that those skilled in the art can further understand the present invention, without restricting their rights.
[0012] Reference figure 1 , A mandrel-free continuous melting furnace for drawing quartz glass rods, including continuous melting furnace, continuous melting furnace is provided with furnace body 1, furnace body 1 is provided with tungsten-molybdenum crucible 3, and the bottom of tungsten-molybdenum crucible 3 is provided with material platform 2, material platform 2 is provided with a discharge port. The upper surface of the material table 2 is set obliquely downward from the inner wall of the tungsten-molybdenum crucible 3 to the discharge port, which can effectively control the downward speed and flow rate of the quartz glass rod, thereby adjusting the quartz glass rod diameter of.
[0013] The upper port of the furnace body ...
