Effect of tension on steel strip in the furnace / Nor Azni Yusoff

Physical defects produce on steel strip due to unsuitable tension applied were identified. The effect of line speed on defect produce was analyzed and grades were recommended. To obtained the result, a steel strip with the same width of 1219 mm and manipulated thickness of 0.35 mm and 0.50 mm was ru...
