Abstract The causes and damage of the important raw material defects such as shell， pits and folding， which influenced the stable operation of Shougang Jingtang 1420 Pickling Line-Tandem Cold Mill， were described. The working principle of monitoring equipments of raw material defects， i.e.， surface detector and hole detector， was introduced. On-line inspection of steel strip quality after acid pickling by surface detector could effectively avoid the occurrence of stripbreakage. The quality of strip steel after rolling was detected online using the hole instrument， which could avoid unnecessary production loss caused by the flow of the hole to thefollowingprocess. Two groups of on-line detection systems played an important role in ensuring the stable operation of production lines. The material defect control measures proposed in this paper could provide reference for the similar production lines.

Key words： raw material defect surface detector hole detector plan review
