Therefore, the thin rolled steel products are usually cold-rolled with higher cost. With these reasons, we make a study to improve the production line of hot-rolling thin steel plate for the steel hot-rolling mills. This study presents a improving and upgrading process for the production line of hot-rolling steel plate based on methods of Teoriya Reshniya Izobretatelskikh Zadatch (TRIZ).The methods has been well-known and expectations for the steel rolling- metallurgy industry. Applying the basic inventions and the contradictions of TRIZ, we present a simple process to solve problems. In this study, we have discovered the weak points and improved three steps in the production chain. After improving and innovating production methods with repeated experiments, we saw that the new methods reduced by 21.5% (time) compared with the old ones. For the results, we can apply to intrustrial sector in producing hot rolling steel plate and reduce costs.
