Embodiment Construction

[0009] Referring to Figures 1 and 2, a furnace cover 5 is installed above the furnace body 3, and a discharge table 10 is installed at the bottom of the tungsten crucible 6. The discharge table has a discharge port, and the tungsten crucible is hung on the large furnace cover. The tungsten crucible The outer side of the tungsten crucible is a heater 8 and an insulating material 4. There is a small furnace cover 2 on the top of the tungsten crucible. There is a feeding port 1 on the small furnace cover. 9. The difference is that the shaper here is not only circular (referring to the cross section, the same below), but also square, rectangular, triangular, fan-shaped, oval and other shapes; the discharge table has circular, square, Discharge table with rectangular, triangular, fan-shaped, elliptical and other shapes; the shaper installed at the lower end of the core rod is located above the discharge table, and is 3mm or 5mm or 10mm or 15mm or 20mm higher than the upper edge of t...

Abstract

The present invention is one kind of continuously smelting furnace and the method of producing specially shaped quartz tube and quartz rod therewith. The continuously smelting furnace includes furnace body, heater, heat insulating material, large furnace cover, small furnace cover, tungsten crucible, core bar, shaper and discharge stage. Both discharge stage and the shaper located over the discharge stage are circular, square, triangular or in other shapes for producing quartz tube and quartz rod in the corresponding shape. The present invention is superior in that specially shaped quartz tube and quartz rod may be produced by means of selecting shaper and discharge stage in corresponding shape and altering the location of shaper.

Description

[technical field] [0001] The invention relates to a continuous melting furnace for producing quartz products and a method for producing special-shaped quartz tubes, quartz rods and the like. [Background technique] [0002] In existing furnaces for producing quartz tubes and quartz rods, the molder at the lower end of the core rod and the outlet of the discharge table are circular (referring to the cross-section, the same below), and the former is located in or below the outlet. , the holes and outer walls of the produced quartz tubes are circular, and the produced quartz rods can only be circular, which often cannot meet the special needs of some users. [Content of the invention] [0003] The purpose of the present invention is to provide a continuous melting furnace and a method for producing special-shaped quartz tubes and quartz rods. These special-shaped quartz tubes and quartz rods include their shapes and / or holes in the quartz tubes (both refer to cross sections, th...
