The invention discloses a glass
coating suspension deep undercooling fast
directional solidification device and a solidification method thereof. The solidification device comprises a closed furnace body. A glass
pipe, a glass
pipe clamp, a
ball screw, an
induction heater, a
thermal insulation mold shell and a
water cooling copper mold are arranged in the closed furnace body. The glass
pipe in the closed furnace body is placed on the clamp. The clamp is driven by the
ball screw. The glass pipe is filled with
alloy raw materials. The closed end of the glass pipe is located in the inner axial position of the heater. After installation, the closed furnace body is vacuumized and is filled with
argon. A power source of the heater is started for heating, thus the
alloy raw materials are subjected to suspension melting, an
alloy melt is purified, heating is continued, and thus the alloy melt is overheated. The
electric current of the heater is lowered, and a deep undercooling alloy melt is obtained. Under the action of the gravity, the deep undercooling alloy melt enters a mold cavity formed by the
water cooling copper mold and the
thermal insulation mold shell. Fast one-way growth of a block sample is achieved. In the operation process of the solidification method, expensive Ga-In-Sn
liquid alloy is not used, thus production cost is low, and operation is simple and convenient.
