Embodiment 1
[0025] A method of rolling extremely thin niobium strip. Described rolling method comprises two parts of rolling equipment and rolling process:
[0026] The rolling equipment of the present embodiment adopts a 16-roll mill, and the roll profile of the 16-roll mill is: the upper intermediate roll of the 16-roll mill is as follows figure 1 As shown, the cone length is 40mm, and the roll diameter difference is 0.1mm; the lower intermediate roll of the 16-roll mill is as follows figure 2 As shown, the cone length is 40mm, and the roll diameter difference is 0.15mm; the working rolls of the 16-roll mill are as follows image 3 As shown, the work roll is a flat roll with a length of 200 mm and a diameter of 22 mm.
[0027] The material of the upper intermediate roll of the 16-high rolling mill, the lower intermediate roll of the 16-high rolling mill and the work roll of the 16-high rolling mill are all GCr15; the upper intermediate roll of the 16-high rolling mill, the lower inte...
Embodiment 2
[0037] A method of rolling extremely thin niobium strip. Described rolling method comprises two parts of rolling equipment and rolling process:
[0038] The rolling equipment that present embodiment adopts is the same as embodiment 1.
[0039] The rolling process that present embodiment adopts is three-pass rolling:
[0040] 1) The first rolling pass
[0041] Put the niobium strip to be rolled into the 16-roll mill, and carry out the first pass rolling at room temperature. The mechanical parameters of the first pass rolling are: the driving side force is 103-113KN, the operating side force 111-121KN, the left tension is 1.112-1.127KN, the right tension is 0.874-0.884KN, the rolling force is 218-233KN; the thickness of the niobium strip after rolling is 0.04-0.047mm.
[0042] The width of the niobium strip to be rolled in this embodiment is 147-150 mm, and the thickness is 0.10-0.11 mm.
[0043] 2) The second rolling pass
[0044] Put the niobium strip rolled in the firs...
Embodiment 3
[0048] A method of rolling extremely thin niobium strip. The rolling method comprises two parts of rolling equipment and rolling process:
[0049] The rolling equipment used in this embodiment is the same as in Embodiment 1.
[0050] The rolling process that present embodiment adopts is three-pass rolling:
[0051] 1) The first rolling pass
[0052] Put the niobium strip to be rolled into the 16-roll mill, and carry out the first pass rolling at room temperature. The mechanical parameters of the first pass rolling are: the transmission side force is 112-122KN, the operation side force 118-128KN, the left tension is 1.125-1.140KN, the right tension is 0.882-0.892KN, the rolling force is 230-245KN; the thickness of the niobium strip after rolling is 0.036-0.043mm.
[0053] The width of the niobium strip to be rolled in this embodiment is 149-153 mm, and the thickness is 0.09-0.10 mm.
[0054] 2) The second rolling pass
[0055] Put the niobium strip rolled in the first pass i...
