Abstract

The invention discloses a quartz glass annealing furnace. The annealing furnace comprises a furnace body, wherein a furnace chamber is arranged inside the furnace body; a furnace door used for sealing the furnace chamber is arranged on the furnace body; a furnace chamber inner layer, an insulating cotton layer, an insulating brick layer and a pearl stone layer are arranged in sequence from the internal to the external on both sides of the furnace chamber inside the furnace body; a furnace chamber bottom layer, an insulating brick layer and a pearl stone layer are arranged in sequence on the undersurface of the furnace chamber inside the furnace body; a furnace chamber top layer, an insulating cotton layer, an insulating brick layer and a pearl stone layer are arranged in sequence on the upper surface of the furnace chamber inside the furnace body; a plurality of grooves are formed in the opposite surfaces of the inner layer of the furnace chamber; a resistance wire is arranged in each groove respectively; two ends of the resistance wires stretch out from both sides of the furnace body to form terminals. The annealing furnace has the benefits of being convenient to use, high in heating speed, short in annealing time, high in processing efficiency, wide in application range and suitable for the annealing treatment on various quartz glass pieces, such as various quartz glass rods and quartz glass plates, and can reach the temperature required by annealing within 3 hours.

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...
