Abstract

The invention relates to a polycrystalline crucible automatic spraying method. A polycrystalline crucible adopted in the polycrystalline crucible automatic spraying method is a regular container provided with an opening. The polycrystalline crucible automatic spraying method comprises following steps: a transverse spray gun of an automatic spraying machine is controlled to move at a preset speed,and one time of spraying is carried out at preset intervals so as to complete transverse spraying of the internal side surfaces and the internal bottom surface of a polycrystalline crucible sequentially; a vertical spray gun of the automatic spraying machine is controlled to move at a preset speed, and one time of spraying is carried out at preset intervals so as to complete vertical spraying of the internal bottom surface and the internal side surfaces of the polycrystalline crucible sequentially; the transverse spraying operation and the vertical spraying operation are carried out continuously for preset repeat times so as to complete the spraying operation of the polycrystalline crucible. The polycrystalline crucible automatic spraying method is simple in operation, spraying time is shortened, and production power is increased.

Description

technical field [0001] The invention relates to the technical field of crucible spraying, in particular to an automatic spraying method for polycrystalline crucibles. Background technique [0002] In recent years, with the rapid development of the solar energy industry, the demand for polysilicon ingots is gradually increasing, and the polysilicon ingot process has gradually become an important production process in industrial production. [0003] In the polysilicon ingot casting process, the auxiliary materials used in the polysilicon ingot casting process mainly include polycrystalline crucibles. The main component of polycrystalline silicon crucibles is fused silica, and its content is generally greater than 99.5%. At present, the production of polycrystalline crucible mainly includes two processes: slip casting and gel casting. During the production process of the polycrystalline crucible, the polycrystalline crucible needs to be sprayed. For a long time before, the cr...
