Analysis of Properties of Selected Aluminium Alloys, Obtained by Twin Roll Casting Method and Subjected to Cold Rolling Process

Abstract

Modern manufacturing technologies of flat cold-rolled products made of aluminium and its alloys are based on raw materials produced with the use of continuous casting technology. One of the most frequently used integrated production processes, based on continuous casting of metal, is twin roll casting method (TRC). In TRC method liquid metal flows into the area formed by two water-cooled rolls, solidifies and next is deformed (rolled) which allows to obtain strip with several millimetres thickness. Thanks to this, it is possible to eliminate hot rolling stage from the typical production technology, and directly subject obtained sheets to cold rolling process.This paper presents results of cold rolling strain dependency on the mechanical properties of tested aluminium alloys from 1XXX, 3XXX and 8XXX series, produced in the laboratory conditions with the use of TRC method. Furthermore the rolling loads and basic mechanical properties, determined in an uniaxial tensile, were examined.

The effect of degree of deformation on forward slip in experimental research on cold longitudinal rolling of flat bars made from en aw-6063 aluminium alloy

“…This method involves rolling samples at maximum degree of deformation. On the basis of geometric parameters of samples after deformation measurements, the value of the roll bite angle (a ch = 15.58°) friction factor (µ = 0.28) and forward slips were calculated from formulae (1)÷ (7). The deformation ratios of material in paper were defined as relative strain ε and logarithmic strain ε: on the high ε wh , ε h ; on the width ε wb , ε b and on the length ε wl , ε l , respectively.…”
