①The number of roll changes is small, the productivity is high, and high-speed rolling can be realized. ②The 2 roll ring has less melting, scratching and sticking, and the groove marks and wear points on the surface are small in size. Compared with the steel roll ring, the grinding time is short, and the grinding cost is only 1/40 of the steel roll ring. ③The rolling product has high precision and good surface quality (it can make the wire and strip have mirror finish), the waste products are greatly reduced, and the comprehensive performance is significantly improved. ④The amount of pass reduction is increased, and when the total reduction is constant, the power consumption is reduced and energy is saved.
