In view of the phenomenon of the difference in sheet thickness of sintered neodymium iron boron quick-co-agulation sheet,by optimizing and improving the timing procedure of crucible pouring and pouring,the structural composition of the pouring system is designed to increase,and control the assembly coaxiality and tundish angle of the cooling copper roller,so that the thickness difference of the quick-coagulation sheet has been improved.The re-sults show that the proportion of quick-coagulation sheets with different thickness has been reduced from 36.1%to 6.7%,which is 29.4%.The thickness difference enrichment area of the quick-coagulation sheet has been reduced from 0.1 mm～0.15 mm to 0.03 mm～0.06 mm,and the average thickness difference of the sheet has been re-duced from 0.129 mm to 0.046 mm now,which has been reduced by 0.03 mm,which has improved significantly.
