Reducing casting defects in ductile iron castings by optimized pouring system
Main Article Content
Casting simulation technology is an most effective method to provide the predicted information on casting defects such as shrinkage, gas entrapment and non-metalic inclusions. In the study, various version pouring systems have been designed for ductile iron castings in the industrial conditions and a computer-aided design solid modeling program was used in the design of pouring systems for ductile iron castings. Pouring system for ductile iron castings and the gating system ratio of the casting part was selected as 1:3,5:2,5. The flow and solidification of the pouring systems of the casting part was simulated by using magma flow and solidification program. The study clearly shows that the kalpur direct pouring system has revealed that it plays a significant role in preventing non-metallic casting defects in ductile iron castings, such as sand, gas, and slag. In addition, it has been observed in the study that clean parts can be obtained in ductile iron castings with an effective and well-designed pouring system design. The kalpur direct pouring system is recommended to be used in ferrous based castings by FOSECO. The kalpur direct pouring system was used for the first time in ÇİMSATAŞ foundry in the ductile iron castings and the appropriate result was obtained.
