Embodiment 1
[0041] This example provides a preparation process of titanium coils for high-end anodes, the preparation process steps include:
[0042] S1: After forging the titanium ingot into a slab and keeping it warm, the slab is obtained;
[0043] S2: Perform hot rough rolling and finish rolling on the slab to obtain hot coils, and perform online annealing treatment on the hot coils to obtain hot rolled coils;
[0044] S3: Surface treatment and rolling in the first rolling pass are performed sequentially on the hot-rolled coils to obtain cold-rolled coils of the first thickness;
[0045] S4: After performing continuous annealing, surface treatment and rolling in the second rolling process in sequence, the cold-rolled coil of the first thickness is obtained to obtain the cold-rolled coil of the second thickness;
[0046] S5: After degreasing the surface of the cold-rolled coil with the second thickness, anneal the finished product, and after smoothing, the titanium coil for high-end an...
Embodiment 2
[0060] In this example, according to the preparation process of Example 1, a titanium coil for high-end anodes was prepared. Specifically:
[0061] S1: Select grade 0 sponge titanium with a Brinell hardness of 105HB for mixing. The content of main impurities in the sponge titanium after mixing is: Fe content 0.04wt%, O content 0.05wt%, N content 0.007wt%. The titanium ingot was smelted in a furnace, and then the titanium ingot was forged into a slab with a thickness of 180mm. The chemical composition of the slab was tested, and the contents were: Fe content 0.04%, O content 0.052%, N content 0.0071%, and the Brinell hardness of the slab was 110HB, then keep the slab at 860°C for heating, holding time 6h;
[0062] S2: rolling the slab processed in step S1 to a thickness of 3.6mm after hot rough rolling and finish rolling, and then performing online annealing in a continuous annealing furnace at an annealing temperature of 740°C;
[0063] S3: The hot-rolled coil after continuo...
