【 摘 要 】

Using the results of theoretical and experimental research a new rolling mode of long-length rails on the universal rail-and-structural steel mill JSC "EVRAZ Consolidated West Siberian Metallurgical Plant" ("EVRAZ ZSMK") was developed with a reduced number of passes in the breakdown stands. Experimental and industrial testing and implementation of the new rolling mode showed a high technical and economic efficiency of its use - reduction in the specific energy consumption was registered, as well as decrease in rejection of rails due to their surface defects, consumption of mill rolls and increase in mill productivity. The cost- effectiveness after implementation was more than 98 million RUB per year.
