Development and Study of Conditions for Rolling Brass Sheets with Turning Providing Rolled Product Improved Quality

The effect of turning brass sheets before the second pass on unevenness of deformation and alloy grain shape and size is investigated. Results of computer simulation and rolling in a 150 × 235 laboratory mill show that when changing the rolling direction the value specifying deformation unevenness in longitudinal and transverse directions decreases with an increase in the degree of reduction compared with longitudinal rolling. Grain structure formation during longitudinal rolling, as well as with turning, is investigated. Recommendations are developed for improving rolling regimes for L63 brass sheets in the 610×940 twin-roll mill of the Kolchugino Non-Ferrous Metal Processing Plant that as a result of turning improves rolled product quality.
