Ticari saf alüminyumun yönlü katılaştırılması için düzenek geliştirilmesi

Bu çalışmada alüminyum alaşımlarının yönlü katılaştırılabilmesi için doğru sıcaklık kontrolü sağlayabilecek bir deney düzeneği kurulmuştur. Hazırlanan düzenek üzerinde sıcaklık kontrolünün sağlanabilmesi amacıyla hareketli ısı bariyeri, soğutucu ısıtma fırını ve soğutma sistemi entegre edilmiştir. Deney düzeneğinin kalibrasyonu için sıcaklık haritası çıkarılmıştır. Sıcaklık haritası sonuçlarına göre fırının farklı konumlarında kalıp içinde 2,5–4,8$^oC$/cm aralığında sıcaklık gradyan değerleri elde edilmiştir.

A system development for directional solidification of commercialliy pure aluminum

An experimental apparatus which can provide an accurate temperature control was constructed for directional solidification of aluminium alloys. A moving heat barrier, a chill heater and a cooling system was integrated to the system for temperature control purpose. Temperature map was achieved in order to calibrate the apparatus. The results of the temperature map showed that 2.5-4.8$^oC$/cm temperature gradients were obtained in the mold at various positions of the furnace.
