Abstract

The invention discloses a device for measuring a long crystal bar of an ingot furnace. The device comprises two slide grooves which are vertically formed in the top of the ingot furnace, and a measuring system for the height of the long crystal bar, wherein openings of the slide grooves are opposite; the two slide grooves are internally provided with a slide frame which can move freely up and down; a clamp for clamping the long crystal bar is arranged in the middle of the slide frame. The device disclosed by the invention is provided with the measuring system for the height of the long crystal bar, so that the height of the long crystal bar can be rapidly read and recorded and the problem in the prior art that an error is great due to a read angle is solved; meanwhile, as the measurement can be carried out in time, measurement time is shortened, staying time of the long crystal bar in silicon liquid is shortened and the use risk of the long crystal bar is reduced; the long crystal bar is prevented from being stuck in a silicon ingot for growing a crystal and the finished-product rate of the silicon ingot is improved.

Description

technical field [0001] The invention relates to a device for growing crystals in an ingot furnace and a melting test device in the field of photovoltaics, in particular to a measuring device for growing crystal rods in an ingot furnace. Background technique [0002] Ingot casting furnace is a special equipment specially designed for solar energy industry, and it is a necessary equipment for polysilicon ingot casting.
