5 Hot-Rolled Wide Steel Strip Mill

5.1 Production Capacity

5.1.1 The economic production scale shall be determined according to the product mix,raw material supply,and overall plant conditions,etc.in the design.The design capacities of rolling mills of different types,in different specifications and compositions shall not be lower than the values specified in the following table 5.1.1-1-table 5.1.1-4.

Table 5.1.1-1 Specifications and design outputs of conventional hot strip rolling mills

Note:The design output can be determined as the lower limit if the steel strips are relatively narrow or thin,or the proportion of product varieties that are difficult to produce is high,or a hot coiling chamber is used.

Table 5.1.1-2 Specifications and design outputs of thin slab continuous casting and rolling mills

img

Note:The design output can be determined as the lower limit if the quantity of product varieties is large or the percentage of steel strip varieties in narrow width is high.

Table 5.1.1-3 Specifications and design outputs of medium slab continuous casting and rolling mills

img

Note:The design output can be determined as the lower limit if the quantity of product varieties is large or the percentage of steel strips in narrow width is high.

Table 5.1.1-4 Specifications and design outputs of steckel mills

img

Note:The design output can be determined as the lower limit if the steel strips are relatively narrow or thin,or the percentage of product varieties that are difficult to produce is high.

5.1.2 The specifications of the rolling mill shall be selected according to the requirements of article 4.1.2 in this code.
