Russian steel maker EVRAZ will launch unique installations for ultrasonic quality control of rails at ZSMK rolling mill. Five modern installations will be put into operation during 2022 to control surface and internal defects of rails at ZSMK rail and beam shop, as part of the project to modernize the non-destructive testing lines of 25 and 100-meter rails, Two installations of the ultrasonic pulsed mirror-shadow testing method have already been put into commercial operation at the LNK-25 and LNK-100 sites. They are designed to detect macrostructure defects in the area of the head and neck of rail products. These are the first installations in the world that, in addition to symmetrical profiles, can control non-symmetrical types of rails, such as pointed rails. The new equipment automatically saves the control protocol for each rail, which makes it possible to carry out end-to-end certification of each unit of production.In addition, LNK-25 is currently undergoing commissioning tests of another unit designed to control surface defects in rails. The principle of operation of the equipment is based on the use of phased array technology with the possibility of electronically changing the angle of entry of the ultrasonic wave. The units will replace the existing eddy current testing systems, which could also test only symmetrical profiles. Modern equipment will make it possible to investigate different types of rails, including sharp-witted rails and European standard profiles. The most important advantage of the new installations is the ability to control the quality of all areas of the rail, and not just the tread surfaces of the head and base of the sole. A similar unit at LNK-100 will be installed in the 1st quarter of 2022.By the end of 2022, LNK-100 is planning to put into operation another ultrasonic echo-pulse testing method using phased array technology, designed to test internal rail defects. It will also make it possible to control all standard sizes of rails manufactured by EVRAZ ZSMK.EVRAZ is investing more than 440 million rubles in the modernization of equipment for non-destructive testing lines. The project will allow by 2023 to increase the rail production capacity to 1. 59 million tonnes per year, increase the productivity of the shop by reducing the time for setting up equipment when
