The technical scheme realizing above-mentioned purpose and take, including body of heater, being provided with heat-insulation cage device in body of heater, be provided with thermal field attemperator in heat-insulation cage device, described heat-insulation cage device is rectangular cylindrical housing, rectangular cylindrical housing includes 4 steelframe faces, connecting side angle plate between 4 steelframe faces, side gusset bottom is provided with connecting plate, and heat-insulation cage device is provided with gripper shoe, gripper shoe is provided with 3 risers, and described heat-insulation cage bottom of device is provided with heat-preservation bottom；Described thermal field attemperator includes heater block, is provided with 4 blocks of inside holding plates outside heater block, and 4 blocks of inside holding plates are connected with each other by medial angle warming plate, is provided with 4 pieces of heat-insulation plate for external outside inside holding plate, and 4 pieces of heat-insulation plate for external are connected with each other by laterior horn warming plate.
Beneficial effect
Compared with prior art this utility model has the following advantages.
The present invention solves crucible during ingot casting and ruptures the silicon hydrorrhea stream caused and find the most in time, the problem being likely to cause furnace chamber burn through, heat-insulation cage can be met with furnace binding symmetrically, improve thermal field eccentric, there is features such as being easy to assembling, and crystal ingot earning rate can be effectively improved, improve crystal mass, reducing energy consumption, safety is high.
