Description
Technical field
The utility model relates to a kind of continuous induction melting furnace, and particularly a kind of production of quartz tubes continuous induction melting furnace, belongs to production of quartz tubes technical field.
Background technology
Quartz glass tube has good physics, chemical property, as high temperature resistant, corrosion-resistant, Heat stability is good, good insulation preformance etc., is the important novel material of modern science and technology.The wall thickness of quartz glass tube is the major criterion of weighing its performance, the silica tube of same outer diameter specification, and its wall thickness is thicker, and class is higher.At present, domestic silica tube adopts continuous induction melting furnace explained hereafter more, continuous induction melting furnace comprises body of heater and bell, crucible is set in body of heater, crucible outside is provided with electric heater unit, filling heat insulating wall between electric heater unit and body of heater, crucible center arranges core bar, and in crucible, the outflow of quartzy melt is by the material platform control of core bar and core bar lower end.In existing apparatus, quartzy flow of melt is behind the maximum cross-section of material platform, and discharging straight down, finally forms silica tube, and the wall thickness of silica tube is thinner, and class is lower.
Utility model content
According to above the deficiencies in the prior art, the purpose of this utility model is: a kind of heavy wall production of quartz tubes continuous induction melting furnace is provided, the wall thickness of quartz tube of same outer diameter specification is significantly increased, improve silica tube class, improve the quality of products, be convenient to control.
Production of quartz tubes continuous induction melting furnace described in the utility model, comprise body of heater, bell, crucible is set in body of heater, crucible center is provided with core bar, and core bar top is connected with the nut on bell by screw thread, and core bar lower end connection one is positioned at the taper shape material platform of crucible outlet below, material platform is blanking portion by upper end to diameter maximum, to expecting that platform bottom is contraction flow region, between blanking portion and crucible outlet, form material circulation road by material platform diameter maximum, contraction flow region has inside scarp.
Coordinate with the nut thread on bell by core bar, rotatable core bar regulates the height of core bar, thereby adjusts the size of material circulation road, realizes the control to quartzy melt.By contraction flow region is set, make quartzy melt after material circulation road flows out, enter in advance contraction, few owing to now expecting that the temperature of stream declines, therefore amalgamation is better, can produce the silica tube of high wall thickness, improves silica tube class, improves the quality of products.
Described blanking portion diameter increases from top to bottom successively, contraction flow region diameter reduces from top to bottom successively, and contraction flow region diameter reduces speed and is greater than blanking portion diameter increase speed, quartz melt is in the time that blanking portion flows out, and speed is more slow, ensures that material stream is stable, in the time entering contraction flow region, quartz melt shrinks rapidly, completes fusion, to realize high wall thickness before cooling.
Described blanking portion diameter rate of change is linear or non-linear, and contraction flow region diameter rate of change is linear.
Described contraction flow region scarp and bottom angle are 60 °～80 °, and angle is excessive, and wall thickness increases not obvious, and angle is too small, and contraction process is unstable.
Described contraction flow region and blanking portion aspect ratio are 1:2～1:3.
Described core bar upper end is through bell, and its end is provided with a rotary handle, by rotary handle, facilitates the adjusting of core bar.
Quartz melt is after material circulation road flows out, cooling forming rapidly, by contraction flow region is set, quartzy melt is merged fast before cooling, and its external diameter is constant, and wall thickness significantly increases, height and the slope of contraction flow region are rationally set, when quartzy melt is merged along contraction flow region, reach the balance of speed and stability, ensure quality product.
Compared with prior art, the beneficial effect the utlity model has is:
This heavy wall production of quartz tubes significantly increases the wall thickness of quartz tube of same outer diameter specification with continuous induction melting furnace by contraction flow region is set, and improves silica tube class, improves the quality of products; Be connected with nut thread by core bar is set, make to expect that circulation road is easy to control.
