Abstract

The invention discloses an assembly structure for improving the service life of a molybdenum sheet heat preservation screen, which comprises a plurality of mutually overlapped molybdenum sheets; each single molybdenum sheet is divided into a hollow zone, an inner zone, a middle zone and an outer zone sequentially from the center to the outside, wherein a reinforcing crossers is arranged at the middle zone, a plurality of inner support roller mounting holes and outer support roller mounting holes are respectively and annularly distributed in the inner zone and the outer zone of the molybdenum sheet, and inner reinforcing crossers and outer reinforcing crossers are respectively arranged at the inner support roller mounting holes and the outer support roller mounting holes. By changing the existing assembly manner, the deformation strength of each single molybdenum sheet is improved, the deformation strength of the original clearance zone between every two adjacent molybdenum sheets is enhanced, the possibility of deformation is low when a crucible and the molybdenum sheet heat preservation screen are attached at a high temperature state, the service life of the molybdenum sheet heat preservation screen is effectively improved, and the production cost is reduced.

Description

technical field

[0001] The invention relates to the field of temperature field structures of crystal growth furnaces, in particular to an assembly structure and an assembly method for improving the service life of a molybdenum sheet insulation screen. Background technique

[0002] As an important part of the temperature field, the molybdenum sheet insulation screen plays the role of heat preservation and temperature adjustment. Since the existing molybdenum sheet insulation screen is formed by stacking multiple molybdenum sheets, this structure will Deformation is easy to occur under the environment, and the deformation will affect the fit between the crucible and the molybdenum sheet insulation screen, resulting in a decrease in the insulation effect of crystal growth, and a very bad influence on the internal quality of the crystal (product). Therefore, the deformed molybdenum sheet insulation screen must be replaced. According to the usage statistics, the existing molybden...
