The first geared motor is rotated forward from the first geared motor to connect the geared shaft and the shaft to the chain gear and the chain so that power is transmitted and rotated forward.

The bevel gear for connection to the shaft rotated by the first geared motor transmits the rotational force to the drum bevel gear.

Subsequently, the first drum and the second drum are rotated to rotate the first rotating roll having a "ㅛ" shape.

At this time, the lower support frame and the second roller conveyor are descended to the cooling tank part while the driving wire for lifting and lowering wound around the first rotating roll is released.

Next, the solution-alloyed aluminum alloy plate co-located on the second roller conveyor in the cooling tank part is quenched by cooling water for 15 minutes at a temperature of 30 degrees. The quenching time may vary depending on the thickness.

Next, in the elevator unit of the elevator-type quenching apparatus, the quenching-completed aluminum alloy plate which is located together on the second roller conveyor in an elevator elevating manner is raised entirely.

It is reversely rotated in the first geared motor is connected to the bevel gear of the (200) shaft received power from the geared motor is reversed.

The bevel gear for connecting the power transmitted from the geared motor rotated by the first geared motor transmits the rotational force to the drum bevel gear.

Subsequently, the first drum and the second drum are rotated to rotate the second rotary roll having a "ㅛ" shape.

At this time, when the balance weight is lowered while the balance weight driving wire wound on the second rotating roll is released, the lower support frame and the second roller conveyor are slowly raised upward in the cooling tank part.
