Abstract
The invention discloses a kind of continuous induction melting furnace and manufacturing process of producing quartz glass bar, comprise the body of heater, the bell that cooperatively interact, tungsten crucible is provided with in body of heater, the outside of tungsten crucible is provided with net with heating function and the insulation sand of connection electrode, fire door place is provided with high temperature brick, water jacket, dust exhaust, tungsten crucible upper end is communicated with feeding device and heat-proof device, and tungsten crucible lower end connects shaped device.Continuous induction melting furnace of the present invention eliminates tungsten crucible internal core rod device, by the shaped device of tungsten crucible bottom, at a certain temperature, draws shaping.Owing to there is no core bar device, there is no bubble, gas line and black core, and the diameter of the quartz glass bar manufactured is large, is widely used in the industries such as semi-conductor, sun power and optical fiber.
Description
Technical field
The present invention relates to a kind of device and manufacturing process of continuous seepage quartz pushrod.
Background technology
Existing continuous induction melting furnace can not produce high-end silica tube rod, there is following defect in the method for producing quartz glass bar: in continuous induction melting furnace, is provided with core bar, by regulating core bar device position, regulates blanking, the mode vacuumized by core bar negative pressure makes pipe become rod, because technique falls behind, small dimension can only be produced, and product there is bubble gas line, owing to there being core bar device, so black core is with by the rod produced, high-quality product cannot be produced, seriously limit its range of application.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is to provide a kind of continuous induction melting furnace and manufacturing process of producing quartz glass bar, and the quartz glass bar of production does not have bubble, gas line and black core.
For solving the problems of the technologies described above, technical scheme of the present invention is achieved in that a kind of continuous induction melting furnace producing quartz glass bar, comprise the body of heater, the bell that cooperatively interact, tungsten crucible is provided with in body of heater, the outside of tungsten crucible is provided with net with heating function and the insulation sand of connection electrode, and fire door place is provided with high temperature brick, water jacket, dust exhaust, described tungsten crucible upper end is communicated with feeding device and deoxygenation disrupter, and tungsten crucible lower end connects shaped device.
Another kind of technical scheme is: a kind of manufacture craft of producing the continuous induction melting furnace of quartz glass bar, and its processing step is as follows:
A, by glass sand through feeding device and deoxygenation disrupter, join continuously in tungsten crucible;
B, quartz sand are heated to 2000 ~ 2400 DEG C and keep, and quartz sand is fully melted, impurity fully volatilizees, bubble dissipates;
When c, quartz sand pass through the shaped device of tungsten crucible lower end, temperature reduces, and the quartzy liquation of fully fusing oozes;
D, then by the control of automatic control system, the quartz pushrod of pull-out diameter 3 ~ 180mm.
Further, its processing step is as follows: in described step b, quartz sand is heated to 2150 ~ 2250 DEG C.
The technique effect that the present invention reaches is as follows: continuous induction melting furnace of the present invention is omitting elements invention, eliminates tungsten crucible internal core rod device, by the shaped device of tungsten crucible bottom, at a certain temperature, draws shaping.Owing to there is no core bar device, there is no bubble, gas line and black core, and the diameter of the quartz glass bar manufactured is large, is widely used in the industries such as semi-conductor, sun power and optical fiber.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention produces the continuous induction melting furnace of quartz glass bar.
Embodiment
As shown in Figure 1, for the present invention produces the continuous induction melting furnace of quartz glass bar, comprise the body of heater 4, the bell 3 that cooperatively interact, tungsten crucible 12 is provided with in body of heater 4, the outside of tungsten crucible 12 is provided with net with heating function 11 and the insulation sand 5 of connection electrode 10, and fire door place is provided with high temperature brick 6, water jacket 7, dust exhaust 9, tungsten crucible 12 upper end is communicated with feeding device 1 and deoxygenation disrupter 2, and tungsten crucible lower end connects shaped device 13.Compared with prior art, eliminate core bar device in continuous induction melting furnace, glass sand is directly injected in tungsten crucible 12, draws shaping by shaped device 13.
Use the present invention to produce the continuous induction melting furnace of quartz glass bar, its processing step is as follows:
A, by glass sand through feeding device 1 and deoxygenation disrupter 2, be added in tungsten crucible 12 continuously;
B, quartz sand are heated to 2000 ~ 2400 DEG C and keep, and the optimum temps that quartz sand is heated to is 2150 ~ 2250 DEG C.Quartz sand is fully melted, impurity fully volatilizees, bubble dissipates;
When c, quartz sand pass through the shaped device 13 of tungsten crucible 12 lower end, temperature reduces, and the quartzy liquation of fully fusing oozes;
D, the size then passing through change discharge port and length and supplementary controlled system, the quartz pushrod 8 of pull-out diameter 3 ~ 180mm.Automatic control system is existing equipment, comprises laser diameter measuring instrument, instrument and computer etc., does not repeat them here.
The above, be only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.
