High Precision 20 High Cold Rolling Mill For AHSS SUS Steel (750)
20-high cold rolling mill for production of the stainless steel precision strip as well as high-strength carbon steel strip, copper, copper alloys, and special materials in perfect quality.
20Hi cold rolling mill undoubtedly is the optimum solution of thickness reducing for hard deformation alloy strips such as stainless steel strip.
The 750mm 20Hi mill proposal is made as per the marketing requirements of finished product and feasible machine configuration, which can guarantee producing all the required product sizes in stability at economical cost and thus good profit.
