Quart continuous melting furnace

Abstract

The invention relates to a quartz continuous melting furnace, which comprises a furnace body, a tungsten crucible arranged inside the furnace body, and a thermal insulation layer arranged between the tungsten crucible and the furnace body wall, wherein the top of the tungsten crucible is provided with a material feeding pipe and a tungsten core rod protection gas inlet, the bottom of the tungsten crucible is provided with a forming device material table, the middle of the material table is provided with a forming port, the forming port position is provided with a tungsten core rod, and a heating device is arranged outside the tungsten crucible, and comprises a molybdenum electrode and a molybdenum network. The quartz continuous melting furnace has the following advantages that: the molybdenum network uniformly covers the external of the crucible, the crucible is uniformly heated so as to reduce intrinsic quality defects such as bubbles and gas lines of the formed quartz pipe, a diameter range of the forming port is 3-400 mm, and the large diameter quartz pipe can be produced.

AI Technical Summary

Benefits of technology

This invention relates to making larger silica glass tubing with smaller diameters by creating an opening through one end that allows for easier handling or transportation of these small pieces during manufacturing processes.

Problems solved by technology

This patented technology describes an improved method for controllably heating materials during production processes such as glass making or metal manufacturing. However, current methods have limitations due to the use of molysilicon rods instead of electricity-based heat sources like graphite rodlets. These technical problem addressed by these inventors include nonuniform temperature distribution caused by long distances between two different types of material being treated simultaneously, which can lead to lower efficiency rates at high temperatures compared to other techniques.
