Example Embodiment
[0050] Example 1: A alloy, the size of the aluminum alloy plate is 80mm×500mm×1500mm, and there are 4 pairs of nozzle rows, which have the characteristics of the four types of nozzle rows of the present invention. The angle between the direction of spraying water and the plane of the roller table during quenching Adjusted to 90°, the vertical distance between the nozzle and the surface of the aluminum alloy plate is adjusted to 150mm. After the aluminum alloy plate is sent to the roller table, it passes through the first pair and the second pair of nozzle rows at a speed of 100mm / s, at a speed of 10mm / s. Through the third and fourth pairs of nozzle rows, the flow density of the first pair of nozzle rows spraying water on the aluminum alloy plate is 10L / (m 2 ·S), the pressure of the water leaving the nozzle is 0.5MPa, and the flow density of the water sprayed by the second pair of nozzle rows on the aluminum alloy plate is 20L / (m 2 ·S), the pressure of the water leaving the nozzle ...

[0051] Example 2: B alloy, the size of the aluminum alloy plate is 120mm×500mm×4000mm. In this embodiment, 6 pairs of nozzle rows are designed, among which the first pair of nozzle rows has the characteristics of the first type of nozzle rows of the present invention, and the second The pair and the third pair of nozzle rows have the characteristics of the second type of nozzle row according to the present invention, the fourth pair of nozzle rows have the characteristics of the third type of nozzle row according to the present invention, and the fifth and sixth pairs of nozzle rows have the present invention The characteristics of the fourth type of nozzle row; the angle between the direction of spraying water and the plane of the roller table during quenching is adjusted to 45°, the vertical distance between the nozzle and the surface of the aluminum alloy plate is adjusted to 50mm, and the aluminum alloy plate is sent to the roller table at 200mm / s through the 6 pairs of nozzl...
Example Embodiment
[0052] Example 3: C alloy, the size of the aluminum alloy plate is 150mm×500mm×4000mm, 4 pairs of nozzle rows are provided, which have the characteristics of the four types of nozzle rows of the present invention. The direction of spraying water above the roller table during quenching is consistent with that of the roller table. The angle of the plane is adjusted to 65°, the angle between the direction of spraying water under the roller table and the plane of the roller table is adjusted to 65°, the vertical distance between the nozzle and the surface of the aluminum alloy plate is adjusted to 75mm, and the aluminum alloy plate is sent to the roller table at 300mm / The speed of s passes through the first and second pairs of nozzle rows in turn, passes through the third pair of nozzle rows at a speed of 200mm / s, passes through the fourth pair of nozzle rows at a speed of 100mm / s, and sprays through the first pair of nozzle rows in turn The flow density of water on the aluminum allo...
