Analysis of operational indicators and ways to improve the efficiency of transport service of the rolling mills at metallurgical enterprises

The article analyzes the transport service of the cold rolling plant. The additional downtime of the railway carriages in the freight areas and at the station serving the plant has been defined. The factors influencing the process in question have been established. It was found that the loading process itself is carried out according to sophisticated transport technology that provides consistent service of significant amount of the rolling rolls freight areas with powerful locomotives and the supply and cleaning of the railway carriages carried out by small groups as well. It was determined that the share of transport operations is more than 55% of the total time of technological operations in the rolling mills transport and freight complexes. It has been stated that the combined actions of all these factors directly influence on operational indicators in the transport and freight complexes of rolling mills when shipping finished products, the volume of transportation increases and that is manifested as the maximum loading of the station capacities, additional downtime of railway carriages and the use of locomotive time. It has been stated that the proper estimation of transport maintenance of rolling mills becomes an important scientific and technical task. That will make it possible to work out a new approach to increasing the efficiency of transport technologies in transport and freight complexes
