A drawing color quartz glass tube continuous furnace, comprising a furnace body and a tungsten crucible in the furnace body, between the tungsten crucible and the furnace wall is provided with a heat insulation layer, a heating device is arranged between the crucible and the insulating layer, the tungsten crucible bottom round forming outlet, the tungsten crucible is arranged in the middle part of the core rod, due to the addition of high temperature curing temperature quartz liquid trace element changes, the external crucible forming device is arranged below the molding outlet, added in order to prevent trace elements in high purity quartz sand in the molten state the tungsten crucible in its internal oxidation, added a molybdenum crucible; in order to fix the molybdenum crucible temperature, increased. A frame of a six prism antioxidant between the tungsten crucible and molybdenum crucible. For the production of laser with UV filter quartz glass tube, liquid special anti quenching super strength green quartz glass tube, an electric heater and a microwave oven with a gray quartz glass tube, good stability and consistency, the error of finished products of small size, high efficiency to achieve continuous production.
