Technical field
The utility model relates to inorganic non-metallic continuous induction melting furnace technical field, specifically a kind of continuous induction melting furnace of producing the regular hexagon silica tube.
Background technology
Fast development along with society and urban construction, use to large-power lamp and light wave, photovoltaic product is more and more, also more and more higher to its specification of quality, still, produce the direct raw material-silica tube of large-power lamp and light wave, photovoltaic product, but keeping for a long time decades consistent.The silica tube of producing by the continuous smelting method at present, Φ is generally at 3-220 mm.Continuous induction melting furnace tungsten rod bottom great majority used are all circular, and the former mouth is also circular, and the silica tube of production is all also circular.Therefore, certainly lead to two problems, the one, with this silica tube material produce, the form dullness of large-power lamp out and light wave, photovoltaic product, be difficult to have breakthrough in form, to reach novel purpose.Although also have at present some enterprises to produce several special pipes, also be difficult to satisfying the market and social demand.The 2nd, the silica tube of producing with this continuous induction melting furnace is inferior, scrap rate is relatively high.This smelting furnace is difficult for Exhaust Gas impurity and liquid impurity when fused quartz powder, cause the purity of quartzy melt not high, easily cause the inner quality defect such as bubble, gas line of moulding silica tube, this has just affected the benefit of manufacturing enterprise to a certain extent, also wasted social resources, need to obtain progress and development at Innovation simultaneously.
Summary of the invention
goal of the invention: the technical problems to be solved in the utility model is, make a kind of continuous induction melting furnace of producing the regular hexagon silica tube, relatively thin and tall tungsten crucible is arranged in this continuous induction melting furnace, the regular hexagon tungsten rod that orthohexagonal former and an end match with former is equipped with in the bottom of tungsten crucible, can directly be pulled produce there is no bubble, the orthohexagonal high-quality silica tube of gas line.
the utility model is achieved through the following technical solutions:
A kind of continuous induction melting furnace of producing the regular hexagon silica tube, comprise the body of heater shell and be located at the tungsten crucible in body of heater, in the periphery of tungsten crucible, vertical molybdenum bar is installed, the thermal insulation layer formed a circle being peripherally equipped with of molybdenum bar, be equipped with in the outside of thermal insulation layer the water-cooled tube that spirrillum is spiraled.In the upper flat of continuous induction melting furnace, the molybdenum ring is housed, in the lower flat of continuous induction melting furnace, lower molybdenum ring is housed; Molybdenum bar vertically be evenly arranged in tungsten crucible around, its upper end is fixed on upper molybdenum ring with the molybdenum screw respectively, its lower end is fixed on lower molybdenum ring with the molybdenum screw respectively.Filling tube is equipped with at top at continuous induction melting furnace; Former is equipped with in bottom at tungsten crucible; Axis part at tungsten crucible is equipped with tungsten rod.
Described tungsten crucible Ф 800mm, height 1800mm, be thin and high form.
The thickness of described former is 100mm, have the regular hexagon molding port in the central position of former, the screw thread of the periphery of former matches with the tungsten crucible bottom thread, and the stubborn bottom that is arranged on tungsten crucible that connects, or when making tungsten crucible, directly will be with former casting forming together with tungsten crucible of regular hexagon molding port.
In described tungsten rod, be hollow structure, its upper end is tungsten rod protection gas entrance, and its lower end shape fabricating becomes the regular hexagon corresponding with the regular hexagon molding port of former, and is inserted in the regular hexagon molding port; Described tungsten rod can be finely tuned up and down; Spacing between tungsten rod and regular hexagon molding port is 3-6 mm.
beneficial effect:
1, compared with prior art, the present invention has adopted Ф 800mm tungsten crucible, and the height of tungsten crucible is increased to 1800mm, in the tungsten crucible top design, 6 group of 12 cover molybdenum electrode arranged, the tungsten crucible heating rod is designed to 64 molybdenum bars, when the high purity quartz raw material is put into continuous induction melting furnace tungsten crucible high-temperature fusion, increase due to tungsten crucible volume and length, the melt raw material sedimentation time extends, be beneficial to the gaseous impurities of discharging in the melt process, improve the purity of melt, the inner quality defects such as the bubble of minimizing moulding silica tube, gas line.
2, after the molding port of former and tungsten rod all are designed to the regular hexagon shape, in normal production, through finely tuning up and down the tungsten rod in molding port, but direct production goes out the regular hexagon shape silica tube that wall thickness is 3-8 mm, to increase novelty and the suitability of silica tube.
