(3) ingot casting is put into hot rolls again, pressure be 700T, temperature is rolled under being 520 DEG C of conditions, controlled rolling speed is 0.4m/min, and rolling obtains woollen sheet material; Again woollen sheet material is put into process furnace and be heated to 400 DEG C, insulation 7h carries out process annealing process, put into hot rolls again, pressure be 700T, temperature is rolled under being 470 DEG C of conditions, controlled rolling speed is 0.5m/min, rolling obtains sheet material and puts into process furnace and be heated to 380 DEG C, and insulation 8h carries out process annealing process
(4) it is cold rolling that sheet material hot rolling obtained carries out 5 passages, and the cold roling reduction of final passage is 15%, and final rolling thickness is 0.8mm,
(5) sheet material is placed in 370 DEG C of 5 hours heat-up times of annealing furnace temperature; Then be cooled to 300 DEG C of insulations 4 hours,
(6) surface treatment step is carried out: first adopt sandblasting to carry out removing foreign material and roughening treatment to magnesium alloy plate surface, then on magnesium alloy plate, thermal spraying aluminum alloy is carried out, afterwards at 370 DEG C, be incubated 5 hours, 300 DEG C of insulations 3 hours are down to afterwards with the rate of temperature fall of 20 DEG C/h, 180 DEG C of insulations 4 hours are down to afterwards with the rate of temperature fall of 20 DEG C/h, obtain magnesium alloy sheet, thermal spraying aluminum alloying constituent is: Zn8-9%, Cu5-6%, Cr1-2%, Mg0.5-0.6%, Sn0.5-0.6%, and surplus is aluminium and inevitable nonmetal inclusion.
7. the preparation method of magnesium alloy sheet as claimed in claim 6, thermal spraying aluminum alloying constituent is: Zn8%, Cu5%, Cr1%, Mg0.5%, Sn0.5%, and surplus is aluminium and inevitable nonmetal inclusion.
8. the preparation method of magnesium alloy sheet as claimed in claim 6, thermal spraying aluminum alloying constituent is: Zn9%, Cu6%, Cr2%, Mg0.6%, Sn0.6%, and surplus is aluminium and inevitable nonmetal inclusion.
9. the preparation method of magnesium alloy sheet as claimed in claim 6, thermal spraying aluminum alloying constituent is: Zn8.5%, Cu5.5%, Cr1.5%, Mg0.55%, Sn0.55%, and surplus is aluminium and inevitable nonmetal inclusion.
10. the preparation method of magnesium alloy sheet as claimed in claim 6, thermal spraying aluminum alloying constituent is: Zn8.3%, Cu5.6%, Cr1.8%, Mg0.53%, Sn0.51%, and surplus is aluminium and inevitable nonmetal inclusion.
