镁合金板卷的控温轧制工艺
摘要：
本发明公开了一种镁合金板卷的控温轧制工艺，其步骤是：（1）镁卷板材补热并开卷；（2）板材补热并调节镁合金板材的转向方向；（3）测板材张力并控制卷曲力大小；（4）对即将咬入板材部分进行整体控温；（5）对即将咬入板材部分的宽度方向进行梯度控温；（6）板材经控温轧辊进行精轧变形；（7）测板材张力并控制卷曲力；（8）板材补热并调节镁合金板材的转向方向；（9）板材补热并卷曲成卷；（10）若此镁板卷板材厚度未达到目标镁板厚度（t0）时，把镁板卷按工艺步骤在可逆控温轧机上逆向重复步骤（1）-（9），进行下一道控温精轧加工；（11）若轧制后镁板材厚度达到目标镁板厚度（t0）时，即获得满足厚度要求的镁合金板卷。
摘要（英）：

The invention discloses a temperature-controlled rolling technology of magnesium alloy coiled sheets. The steps comprise: (1) performing heating compensation on a magnesium coiled sheet and uncoiling the magnesium coiled sheet; (2) performing sheet heating compensation and adjusting turning directions of the magnesium alloy sheets; (3) measuring tension of the sheet and controlling a crimp force value; (4) performing integrated temperature control on a part which is to bite into the sheet; (5) performing gradient temperature control on the width direction of the part which is to bite into the sheet; (6) through a temperature-controlled roll, performing finishing rolling on the sheet and the sheet deforming; (7) measuring tension of the sheet and controlling a crimp force; (8) performing sheet heating compensation and adjusting turning directions of the magnesium alloy sheets; (9) performing sheet heating compensation and coiling the sheet in rolls; (10) if the thickness of the magnesium plate coil sheet does not reach the thickness (t0) of a target magnesium plate, reversely repeating the steps (1)-(9) on magnesium coiled sheets on a reversible temperature-controlled rolling mill according to the process steps, performing next temperature-controlled finish rolling processing; (11) if the thickness of the magnesium sheet reaches the thickness (t0) of the target magnesium plate, obtaining the magnesium alloy coiled sheet satisfying the thickness requirements.
