Furnace parameter measuring method for vacuum fiberglass

Abstract

The invention discloses a furnace parameter measuring method for vacuum fiberglass. The furnace parameter measuring method comprises two sliding grooves and a measuring system, wherein the two sliding grooves are formed in the top part of an ingot casting furnace and are vertically arranged; openings of the sliding grooves are opposite to each other; a sliding frame which can freely move up and down is arranged in the two sliding grooves; a clamp which is used for clamping a crystal growing bar is arranged at the middle part of the sliding frame; the measuring system is used for measuring the height of the crystal growing bar. Through the arrangement of the measuring system for measuring the height of the crystal growing bar, the height of the crystal growing bar can be rapidly read and recorded, and the problem of big error caused by the existence of a reading angle in the prior art is solved; meanwhile, measurement is timely carried out, the measurement time is shortened, the time when the crystal growing bar remains in silicon liquid is reduced, and the using risk of the crystal growing bar is reduced; the crystal growing bar is prevented from being adhered into a silicon ingot in crystal growing, and a rate of finished products of the silicon ingot is increased.
