Küresel vanalar, petrol boru hatlarından barajlara kadar çok yaygın kullanım alanına sahip endüstriyel malzemelerdir. Son yıllarda maliyet azaltma ve performans artışı beklentisiyle çeşitli tip ve tasarımlarda vanalar üretilmektedir. Bu durum sonucunda özellikle vana gövdelerinde çok farklı kesit kalınlıkları elde edilmektedir. Döküm yöntemi ile üretilen vana gövdelerinde kesit kalınlıklarındaki bu farklılaşma, bazı alaşım gruplarında sıcak yırtılma riskini ortaya çıkarmaktadır. Bu çalışmada 1.0619 çelik alaşımından dökülen bir vana gövdesi parçasında meydana gelen sıcak yırtılma hatasının kök nedeni araştırılmış ve sonrasında döküm tasarımı optimize edilerek hatasız bir ürün üretilmiştir.

Globe valves are industrial materials with a wide range of uses, from oil pipelines to dams. In recent years, valves of various types and designs have been produced with the expectation of cost reduction and performance increase. As a result of this situation, very different section thicknesses are obtained, especially in valve bodies. This variation in cross-section thicknesses of valve bodies produced by casting method reveals the risk of hot tearing in some alloy groups. In this study, the root cause of the hot tear failure occurring in a valve body part cast from 1.0619 steel alloy was investigated and then a defect-free product was produced by optimizing the casting design.
