Abstract

The invention discloses equipment for directly growing a sapphire fairing. The equipment comprises a rack, a furnace body, a crucible and a capillary guide mold, wherein a rotating component is arranged below the rack and comprises a fixed frame, a rotary motor and a drive rod; the crucible can be driven by the rotary motor to rotate; a support is arranged above the furnace body; a longitudinal moving mechanism and a horizontal moving mechanism are arranged on the support; the horizontal moving mechanism is connected with the longitudinal moving mechanism; a torque motor is arranged on the horizontal moving mechanism; a seed rod fixed frame is arranged on an output shaft of the torque motor; the capillary guide mold is vertically arranged in the furnace body and is installed on the crucible via a fixed clamp; the lower end of the capillary guide mold extends in the crucible; a through hole through which a seed rod can pass is formed in the top of the furnace body; and the seed rod can move horizontally in the through hole. The equipment can effectively reduce the processing difficulty and improve the production efficiency.

Description

technical field [0001] The invention relates to the technical field of fairing production, in particular to a device for directly growing a sapphire fairing. Background technique [0002] As an optical material, sapphire is more and more widely used in infrared military equipment and satellite window materials due to its good light transmission in the 0.2-5μm band and its excellent physical, chemical and mechanical properties. Compared with other materials of the same application (MgF2, ZnS, etc.), sapphire has extremely high mechanical strength, good heat resistance, good chemical corrosion resistance, and good wave transmission in a wide band (visible light, infrared, microwave) , so its application is getting wider and wider. Especially with the rapid development of missile technology in recent years, the advantages of sapphire as a fairing and window material have become more and more obvious, and the quality requirements for sapphire fairings are getting higher and hig...
