In order to meet the severe requirements of market and reduce production costs of high quality steels,advanced run-out table cooling based on ultra fast cooling(UFC) and laminar cooling(LC) was proposed and applied to industrial production.Cooling mechanism of UFC and LC was introduced first,and then the control system and control models were described.By using UFC and LC,low-cost Q345B strips had been produced in a large scale,and industrial trials of producing low-cost dual phase strips were completed successfully.Application results show that the ultra fast cooling is uniform along the strip width and length,and does not affect the flatness of strips.The run-out table cooling system runs stably with a high precision,and makes it possible for the user to develop more high quality steels with low costs. 展开更多

In contrast to inorganic solar cells, organic solar cells (OSCs) show advantages such as low cost, light weight, and flexi- bility. In fact, the most attractive feature of OSCs is that they could be produced in large scale and at low cost by roll-to-roll printing, just like printing newspapers, which does not in- volve complicated and high-cost procedures that are required in the production of inorganic solar cells. It is this fascinat- ing feature that has drawn great attention on the OSC study during the past two decades. 展开更多
