| Abstract | The paper provides results of analysis of tensions in the inter-stand gaps of the continuous sub-train of the 2,000 mm mill roughing train of OJSC Magnitogorsk Iron and Steel Works. It shows that the existing system of automated no-pull control does not fulfil modern requirements. Reasons of the roll product dimensional accuracy reduction at the gauge diversification have been defined. The main reason is presence of uncontrolled longitudinal forces in the strip between tandem stands. The study offers the algorithm of electric drive speed mode control based on the calculation of the static load moments for modes of the separate and simultaneous rolling. According to the algorithm, electric drive speed control is performed based on the results of comparing the calculated moments with the set reference values. Results of experimental studies of this algorithm at 2,000 mm mill are provided. Improvement of the tension control accuracy by the factor of 2-2.5 has been proved. The paper emphasizes advantages of the commercial introduction of the developed algorithm and lists main technical effects. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
