Abstract

The invention discloses a quartz glass annealing furnace, which comprises a furnace body. A furnace is arranged in the furnace body. A furnace door for closing the furnace is arranged on the furnace body. Layer, thermal insulation cotton layer, thermal insulation brick layer and perlite layer, located below the furnace in the furnace body are the furnace bottom layer, thermal insulation brick layer and perlite layer in turn, and located above the furnace in the furnace body are the furnace top layer, thermal insulation cotton layer, thermal insulation brick layer and Perlite layer; a plurality of grooves are symmetrically arranged on the opposite surface of the inner layer of the furnace, and resistance wires are respectively arranged in each groove, and the two ends of each resistance wire are led out from the two sides of the furnace body respectively. The beneficial effects are: easy to use, fast heating speed, three hours to reach the temperature required for annealing, short annealing time, high processing efficiency; wide application range, suitable for annealing various quartz glass parts, such as various quartz glass rods and quartz glass plates, etc.

Description

technical field [0001] The invention relates to a quartz glass heat treatment equipment, in particular to a quartz glass annealing furnace. Background technique [0002] Quartz glass has become an important basic material due to its excellent physical and chemical properties such as high purity, high temperature resistance, high thermal stability, high light transmittance, good chemical stability and low thermal expansion rate. It is widely used in microelectronics, Optical fiber communication, laser, sensing technology, instrumentation and other high-tech fields. In recent years, with the development of science and technology, quartz glass has become more and more widely used in national defense. For example, it has become an indispensable material in the fields of space technology, radar, nuclear engineering, etc., and the quality requirements for quartz glass are also increasing. High, one of the conditions that quartz glass needs to meet in many cases is stress-free, an...
