Embodiment 1
[0105] The rolling product type is selected as AZ31, the width of the incoming material is 600mm, the thickness of the incoming material is 6.0mm, the thickness of the magnesium alloy wide sheet product is 1.5mm, and the width l is 1600mm.
[0106] Such as Figure 1~2 Shown, the processing method of magnesium alloy cast-rolled plate preparation wide-width thin plate is characterized in that: the rolling process of magnesium alloy wide-width thin plate comprises the following steps:
[0107] (1) Determination of the shape and size of the wide thin plate rolling billet, the cross section of the wide thin plate rolling billet includes a middle thin area, thick areas are set on both sides of the middle thin area, and a transition area is used to connect the thick area and the middle thin area. The blank thickness in the transition zone decreases continuously from the thick zone to the intermediate thin zone.
[0108] The reduction rate ε of the middle thin area of the billet in...
Embodiment 2
[0131] The rolling product type is selected as AZ31, the width of the incoming material is 1000mm, the thickness of the incoming material is 8.0mm, the thickness of the magnesium alloy wide sheet product is 1.0mm, and the width is 2000mm.
[0132] Such as Figure 2~3 As shown, the cross-sectional shape of the wide sheet rolling billet includes a middle thin area, and thick areas are set on both sides of the middle thin area. The thick area and the middle thin area are connected by a transition area. area decreases continuously. The transition connection mode of the transition zone in the second embodiment is a straight line transition connection.
[0133] The rolling process of magnesium alloy wide sheet is carried out in the following steps:
[0134] (1) Determination of the shape and size of the rolled billet
[0135] The reduction rate ε of the middle thin area of the billet in the second embodiment b is 10%, then the thickness of the middle thin area after rolling is...
Embodiment 3
[0155] The rolling product type is selected as AZ31, the width of the incoming material is 600mm, the thickness of the incoming material is 6.0mm, the thickness of the magnesium alloy wide sheet product is 1.5mm, and the width l is 1600mm.
[0156] Such as Figure 1~2 As shown, the cross-sectional shape of the wide sheet rolling billet includes a middle thin area, and thick areas are set on both sides of the middle thin area. The thick area and the middle thin area are connected by a transition area. area decreases continuously. The transition connection mode of the third transition zone in this embodiment is a circular arc transition connection.
[0157] The rolling process of magnesium alloy wide sheet is carried out in the following steps:
[0158] (1) Determination of the shape and size of the rolled billet
[0159] In this embodiment three, the reduction rate ε in the middle thin area of the rolled billet b is 15%, then the thickness of the middle thin area after ro...
