Methods of research and analysis of wear gauges rolls wire block // Material working by pressure. – 2019. – № 1 (48). – P. 157–162. The study of roll wear as the main working tool in rolling processes remains an urgent task, despite numerous works in this area. The use of new roll materials, providing higher wear resistance, requires additional study of the features of their wear and improvement of methods for measuring wear. In this regard, the purpose of this work is to develop a methodology for the experimental study of roll wear, using the example of a wire block. Experimental studies of the wear of the rolls of the wire block using a hour indicator and optical-light method are performed. Statistical processing of the obtained data confirmed the uniformity of the measurement results and the possibility of applying the optical-light method as more informative. This method allows you to determine the wear on the entire contour of the grooves of rolls. Studies performed during the rolling of a rod of 5.5 mm in diameter using an optical-light method made it possible to establish that the depth of wear of the rolls of the rolls is unevenly distributed and significantly depends on the nature of the change in the average pressure of the metal on the rolls. Gauge of the fourth and fifth stands, where abrasive wear prevails, are most susceptible to development. In the first two stands, osteous wear is observed. The size of the gap between the rolls also has a certain influence on the wear of the roll gauges. With an increase in this gap, the probability of stalling a roll in caliber increases, which is reflected in its development |
