| titleOfInvention | Energy-saving thermal field structure for sapphire growth furnace |
| abstract | The utility model relates to an energy-saving thermal field structure for sapphire growth furnace, which comprises a furnace body, a crucible shaft, a heater and a heat preservation layer, wherein the heat preservation layer comprises an upper heat preservation layer, a side heat preservation layer and a bottom heat preservation layer, the upper heat preservation layer, the side heat preservation layer and the lower heat preservation layer form a cylinder shape with a hollow part, the heat preservation layer is positioned in the furnace body, the crucible is positioned in the hollow part, the heater is arranged at the periphery of the crucible, one end of the crucible shaft is connected to the bottom of the crucible, the other end of the crucible shaft extends out of the bottom heat preservation layer, and the crucible shaft is hollow to form a channel; the side heat-insulating layer comprises an inner layer, a middle layer and an outer layer, wherein the inner layer is made of tungsten materials, the middle layer is made of zirconia sand and a molybdenum screen, and the outer layer is made of alumina bubble bricks. The utility model discloses a by the long brilliant energy consumption of reduction sapphire that hard brick of zirconia, zirconia sand and molybdenum screen, the temperature field side heat preservation screen of alumina bubble brick preparation can be great, the temperature field cost of manufacture is low, long service life to can change the part that local damage, unnecessary whole change has reduced cost of maintenance. |
