Problems solved by technology

The metal to be heated is placed in a quartz tube for high-frequency heating. Since the metal is to be melted, it will inevitably generate heat radiation to the quartz tube, causing the temperature of the quartz tube to be too high and affecting its service life.

Embodiment Construction

[0009] The present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0010] Such as figure 1 A quartz tube 1 shown has a thread 11 on its outer wall, and a heating coil is wound in the thread groove to heat the metal to be heated in the quartz tube 1 . In practical applications, according to the intensity of heating required, in the case of higher heat requirements, the thread can be set as a forward and reverse thread, and the heating coil can be wound in both forward and reverse directions.

[0011] For better heat dissipation, the thread height is set to be the same as the inner diameter of the quartz tube 1, which can increase the service life of the quartz tube by 50%.

Abstract

The invention discloses a quartz tube. The outer wall of the quartz tube is of a thread shape; a heating coil is directly wound inside a thread groove while a convex thread tooth plays a cooling role, so that the temperature of the quartz tube is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of high-frequency heating, in particular to a quartz tube in a high-frequency melting furnace. Background technique [0002] The purity of metals produced by industrial electrolysis is usually relatively high, up to 99.99%, and the metals that meet the needs of the electronics industry need to reach 99.9999% or even higher purity. At present, the more common smelting method is high-frequency smelting, which uses high-frequency high-current to flow to a heating coil wound into a ring or other shape to heat the metal material to be melted, and then perform other treatments. The metal to be heated is placed in a quartz tube for high-frequency heating. Since the metal is to be melted, heat radiation will inevitably be generated on the quartz tube, causing the temperature of the quartz tube to be too high and affecting its service life. Contents of the invention [0003] Aiming at the deficiencies of the prior...
