Jan 15,2016 20cr4#0183;The results of experimental work on 20Cr4 enabled establishing that the maximum efficiency of nanostructuring burnishing in terms of hardness and HV,H IT is achieved at limiting value of N c 3035 (F b = 200 N,f b = 0.04 mm/rev,v b = 10 m/min, = 0.34).The Wear on Roller Press Rollers Made of 20Cr4/1.7027 This paper defines the wear process of rollers made of 20Cr4.Rollers with a diameter of 1000 mm were installed in a roller press used for the production of drop-shaped briquettes and the copper concentrate was briquetted for 1100 h.Three-dimensional (3D) geometry analysis,metallographic analysis,macroscopy,scanning electron microscopy,as well as hardnessSome results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456Next
