Investigation of Production Parameters, Mechanical Properties and Microstructures of 5005 Aluminium Alloys Produced by St/Cu Shell Pair in TRC
Öz
This study was carried out on the rollers where solidification occurs in the twin-roll casting method, which is one of the flat product production methods. The rollers where solidification occurs consist of two components, core and shell, and the shell material is cooled by water circulating between the core and shell. The shell and the core material are connected to each other using a shrink-fitting method. Since cast rolls are exposed to high loads and thermal cycles during solidification, alloy forged steel is commonly used as the shell material. It is known that the copper element has a much higher thermal conductivity coefficient than steel. For this reason, copper shell material can be used industrially instead of steel due to the properties that affect the material and production, such as rapid solidification and increase in productivity. In this thesis study, instead of alloy steel/steel shell, a steel shell pair was used in the upper roll and a beryllium alloy forged copper shell pair was used in the lower roll, and the effects of this shell pair on the parameters, microstructures and mechanical properties in the production of 5005 aluminum alloy were examined.
