The invention provides a repairing method for a quartz finished product, and relates to the field of quartz finished product repairing, the repairing method comprises the following steps: opening a line: opening a gas line on the quartz finished product to form a hole-shaped structure; a quartz rod is fused through oxyhydrogen flame to fill the hole-shaped structure, and the oxyhydrogen flame is used for evenly heating the fire repairing position to be in a red state; annealing: eliminating residual stress at the gas line fire repair position at the annealing temperature; and grinding and polishing: grinding and polishing the fire repair position of the quartz finished product. According to the invention, the gas line can be completely eliminated, the geometric dimension and strength of the quartz finished product are not reduced, the quartz finished product can meet the use requirements of the quartz finished product fields of semiconductors, photovoltaics, optical fibers and the like, the rejection rate of the quartz finished product is effectively reduced, and the production cost of the quartz finished product is reduced.
Description
technical field [0001] Embodiments of the present disclosure relate generally to the field of quartz product repair, and more particularly, to methods of repair for quartz finished products. Background technique [0002] The pipe, rod or plate ring structure drawn by the continuous melting method, due to the limitations of the impurities in the quartz sand itself and the technical level of the continuous melting furnace, most of the drawn finished products have gas lines. [0003] The existence of gas lines will reduce the strength of quartz products, making them unusable in the fields of semiconductors, photovoltaics, optical fibers and other quartz products. Such quartz products can only be downgraded or scrapped, which will greatly increase production costs. Contents of the invention [0004] According to an embodiment of the present disclosure, a repair method for finished quartz products is provided, so as to reduce waste, reduce costs, and improve the utilization rat...
