▎ 摘　　要

NOVELTY - Device comprises a vacuum furnace shell (13) whose lower part is provided with a horizontal box body (10). A circulating flow cooling component is set in the horizontal box body. A vertical supporting leg (11) is set at a bottom of two ends of the horizontal box body. A horizontal sealing component is matched with a transverse arc-shaped open sealing sleeve (21). A window is set on one side of an upper part of the horizontal box body. A hinge is located at one side of the window. The circulating flow cooling component is used for circularly radiating and cooling a mold shell. The horizontal sealing component is used for heating an inner container (15). A resistance heater (17) is sealed when smelting. A shuttering telescopic rotating control component is used for matching with the circulating flow cooling component for rotating auxiliary radiating shuttering. USE - Directional solidification device for casting alloy used in coagulation system used for manufacturing large size directional blade for heavy combustion engine. ADVANTAGE - The device has a modularized combined structure that is convenient to assemble and use, and realizes production operation of intelligent automation. The circulating flow cooling component greatly increases casting cooling speed and temperature gradient in the solidification process, thus reducing material solidification segregation, simplifying heat treatment of large casting, saving cost, improving efficiency, and improving tissue stability of the material. The device realizes anti-cracking of the mold shell, graphene nano-ball particles of the rotary mold for extruding and splitting, and graphene nano ball particles to the mold shell. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a coagulation system. DESCRIPTION OF DRAWING(S) - The drawing shows a main view structure schematic diagram of an alloy casting directional solidification device. 10Horizontal box body 11Vertical supporting leg 12Transverse plate 13Vacuum furnace shell 14Inner shell 15Inner container 16Feeding port 17Resistance heater 18Electric wire 19Transverse cylinder seat 20Transverse cylinder 21Cross arc-shaped open sealing sleeve 22Connecting part 23Arc-shaped sealing plate 24Cross cylinder heat insulation sealing ring 25Graphene nano-ball particles 26Second vertical cylinder 27Vertical connecting block 28Mold shell seat limiting block supporting transverse plate 30Vertical rod 41Horn-shaped aggregate block 44Vertical connecting block limiting lug plate 45Vertical connecting block limiting lug plate through-hole 46Second vertical limiting rod 47Semicircular clamping groove 48Circulating feeding pipe 49Circulating particle feeding pump 50Discharging pipe 51Circulating discharging pipe 52Circulating particle discharging pump 57Cold air inlet fan
