Remarks:
The index of the amount of steel passing is mainly determined by the inspection standards of each company. The amount of steel passing through high-speed steel rolls compared with ordinary bainite rolls is 3 to 3.5 times that of a single slot. The total amount) is 4 times and more than that of bainite; under the same process conditions, the passing amount of reinforced high-speed steel A is 15% higher than that of ordinary high-speed steel, and the passing ratio of enhanced high-speed steel B The passing rate of ordinary high-speed steel is 25% higher, and the roll of high-alloy steel is 50% higher than that of ordinary high-speed steel. (Recommended for foreign customers: high-speed steel rolls can be used)
