Embodiment 1
[0040] in the attached figure 1 and 2 In the preferred embodiment shown, take the metal casting and continuous rolling equipment of φ560 / φ980×1820mm specification as an example to produce aluminum alloy slabs, and further illustrate the present invention:
[0041] The thickness of the crystallizer channel is 10mm, casting slabs with a thickness of 8mm, the casting speed is 6-18m / min, the deformation rate of the casting slab is 20-65%, the thickness of the casting and rolling mill exit is 2.8-6.4mm, and the exit speed is 7.2-30m / min.
[0042] Before the vertical plate: the crystallizer is docked with the rolls of the casting and rolling mill, the linear speed of the rolls is set within the range of 6-18m / min, and the gate of the distributor is confirmed to be closed, and the aluminum alloy melt at 680°C-720°C is continuously injected into the front box and Distributor, open the discharge port of the distributor, when the temperature of the melt at the discharge port is close t...
Embodiment 2
[0047] in the attached figure 1 and 2 In the preferred embodiment shown, take the metal casting and continuous rolling equipment of φ540 / φ920×1200mm specification as an example to produce copper alloy slabs, and further illustrate the present invention:
[0048] The thickness of the crystallizer runner is 30mm, casting a slab with a thickness of 25mm, the casting speed is 4-10m / min, the deformation rate of the casting slab is 12-58%, the thickness of the exit of the casting and rolling mill is 10-22mm, and the exit speed is 4.5-16m / min.
[0049] Before the vertical plate: the crystallizer is docked with the rolls of the casting and rolling mill, the linear speed of the rolls is set within the range of 4 to 10m / min, and the gate of the distributor is confirmed to be closed, and the copper alloy melt at 1100°C to 1160°C is continuously injected into the front box and Distributor, open the discharge port of the distributor, when the temperature of the melt at the discharge port ...
