Abstract

The invention discloses a production process for forming large-sized quartz plates at one time. According to the process, high-purity quartz sand is taken as a raw material, is put into a feed hopper of a quartz continuous melting furnace, and is automatically fed through a control system; the length-width ratio of a forming discharge hole of the quartz continuous melting furnace is 550:(20-26); a laser measuring instrument is arranged below the discharge hole of the quartz continuous melting furnace; a horizontal plate drawing machine is adopted for drawing, and a driving motor of the plate drawing machine is provided with a frequency converter connected with the control system; and in the drawing process, the flow of the forming discharge hole is regulated according to the requirements on the width and thickness of the quartz plates, the laser measuring instrument sends the measured data of the quartz plates to the control system, a power supply system of the quartz continuous melting furnace is regulated, and the control system controls the frequency converter to stably draw the quartz plates. The invention also discloses a device for forming the large-sized quartz plates at one time. The device is reasonable in structural design and can be automatically controlled; and by the process, the large-sized quartz plates can be formed at one time on the premise of ensuring product quality.

Description

technical field [0001] The present invention relates to a production process of a quartz plate, especially a production process for one-time forming of a large-size quartz plate using a continuous melting furnace; the present invention also relates to a forming device for one-time forming of a large-size quartz plate using the aforementioned process. Background technique [0002] In the prior art, the maximum size (width) of the quartz plate produced by the traditional continuous furnace production process does not exceed 250mm. Other methods of producing large-scale quartz glass plates in the current technology include: one is to melt quartz sand into quartz glass ingots by means of electric melting or gas refining, and then cut them into quartz glass plates; the other is to use direct The method of melting quartz sand into a quartz glass plate through an electric arc; the third is the method of directly melting the quartz glass plate through gas refining and spraying; the...
