Abstract: The equipment and technology characteristics of endless strip production line in Rizhao steel were analyzed and the achievements of endless strip production in Rizhao steel were illustrated with detailed productive data in 2017. The achievements of endless continuous casting process was introduced from the aspects of the mold level deviation, the casting speed and the tundish temperature. The achievements of endless continuous rolling process was described from the rolling length, the mechanical properties and the microstructure at different position along the width. The achievements of endless continuous casting and rolling process was discussed from the product qualification rate, the yield rate, the thin strip ratio, the accident rate and the energy consumption. The productive practice of endless strip production (ESP) shows that the longest number of continuous casting furnace reached to 15 heats (4500 tons), the longest rolling length in single casting period was 182 km, the qualified rate of products was up to 99.73%, the yield rate was up to 97.51% and the thin strip ratio had a maximum value of 40.57%. At the same time, its accident rate was below 2.02% and its energy consumption was less than 27.26 kgce·ton^-1. These achievements indicated that the ESP line in Rizhao steel had the advantages of low cost, good performance and green manufacturing, so the endless rolling technology will be rapidly promoted and the hot rolled thin products by ESP will further expand the market.

Abstract: With rapid development of internet, various applications based on internet are increasingly highlighted. In the teaching of quality and technology supervision system, there are more and more businesses to use computer and the theory can be combined with practice to complete work with strong profession including inspection and enforcement. It requires staff in the system to learn theoretical knowledge and practice a lot to master knowledge really and play a role in practical application. In the current education and assessment mode, real level of staff cannot be assessed really. In terms of level in the practice aspect, it cannot guide staff to learn these courses with effective means. The online testing system based on Web comes into being under the circumstance. It gradually develops with network technology and database technology. It can test staff at any time with the network, stretching traditional testing room; in addition, network resources can be utilized effectively to service quality supervision cause in a better way.

Abstract: In order to improve the estimation system for the physical education students and to make the evaluation function as completely as possible, we developed a performance evaluation system for volleyball public course and designed an intelligent examination template match with the system, using literature data, questionnaire combined with statistical and computer knowledge. The evaluation system can effectively reflect the training objectives for the physical education students and the characteristics of volleyball sports. It has the guiding role for students. The proposed evaluation template makes the summarization process intelligent and can act as the reference to the role of evaluation for other courses in physical education.
