Period nickel tungsten both sides can produce raw edges, in the mistake of long base band rolling, continuous heat, subsequent coated transition zone and superconducting layer
Broken belt is easily caused in journey, therefore trimming processing is carried out to base band after appropriate rolling reduction can avoid problem above simultaneously
The shearing number of times in the operation of rolling is reduced, and burr can be produced during raw edges is sheared, it is larger in follow-up cold-rolled process
Burr some small pits can be caused to roll particularly work roll surface, and then these pits can be right in cold-rolled process
A certain degree of influence is caused on base band surface, such as produces periodic minute protrusions；In order to improve the production of textured metal base band
Efficiency, prepare one fixed width base band be an effective approach, therefore for wide base band finally need carry out shear slitting into
Required width specifications, due to after rolling base thickness it is relatively thin and after dynamic recrystallization treatment nickel-tungsten alloy base-band hardness compared with
It is low, larger burr is easily produced during slitting is sheared, small in wave and the defect, the above sheared deficit such as during nest
The high performance transition zone of subsequent deposition and superconducting layer can be had a strong impact on.Therefore, after appropriate deflection carry out shear fracture side and
The shearing quality in base band preparation process is controlled to improving the final performance of texture nickel-tungsten alloy base-band and improving production efficiency tool
There is important realistic meaning.
