Apwopriye pou desen gwo twou san fon ak detire bobin asye difisil frèt woule tankou miray, chodyè lwil oliv la ak etaj la. Yo itilize woule frèt tou pou fè bobin ki pi mens pase moulen woule cho yo ka pwodui kounye a (mwens pase 0.8-1.0 mm).
Echantiyon an se echantiyon P6 nan GB/T 228 ak direksyon echantiyon an transverse.
c. Egzijans r90 ak n90 valè aplike sèlman pou detire bobin asye difisil woule frèt ak epesè pa mwens pase 0.50mm. Lè epesè a gen plis pase 2.00mm, valè r90 yo pèmèt yo bese 0.2.
