Abstract

The invention discloses a crucible cover plate. The crucible cover plate comprises a cover plate body used for being arranged on the top of a quartz crucible, and strengthening ribs used for improving the bending strength of the cover plate body are arranged on all corners of the top wall of the cover plate body. According to the crucible cover plate, due to the fact that each corner of the cover plate body is provided with one strengthening rib, the bending strength of the cover plate body can be improved, buckling deformation of the corners is prevented, and the probability of arcing sparking caused by corner buckling of the cover plate body is reduced; in addition, by means of the strengthening ribs, the overall strength of the cover plate body is improved, and prolonging of the service life of the crucible cover plate is promoted; furthermore, after the strengthening ribs are arranged, the bending strength can be improved without increasing the thickness of the cover plate body and reducing the width-to-thickness ratio of the cover plate body, reduction of the material cost and the production cost is promoted, the weight of the whole plate is reduced, and pick-and-place operation of an operator is convenient.

Description

technical field [0001] The invention relates to the technical field of polycrystalline ingots, in particular to a crucible cover plate. Background technique [0002] In the application of polycrystalline ingot technology, silicon raw materials are usually contained in quartz crucibles to prepare desired products. Four crucible guards surround the quartz crucible. The quartz crucible is placed on the bottom plate of the crucible. The top of the quartz crucible is covered with a CC material cover to prevent impurities from falling into the quartz crucible and contaminating the silicon material. The cover is fixed on the crucible. upper side of the shield. [0003] With the development of polycrystalline ingot casting technology, the crucible cover plate for ingot casting widens with the widening of the quartz crucible, making the thickness of the cover plate relatively weaker than the width. It is easy to warp and deform, resulting in an increased probability of corners touc...
