Pressurized gating system design and optimization in steel castings
Main Article Content
Abstract
The aim of this study is to establish a correlation between the proven version of the pressurized gating system for steel castings and the cost-effective version of the pressurized gating system in industrial conditions. In the study, a computer-aided design solid modeling program was used in the design of the pressurized gating system for steel castings and the ratio of the pressurized gating system was selected as 1: 3: 1. Flow simulation of the gating-designed casting part was made in computer-aided design metal casting simulation. In the study, calculations used in the design of the pressurized gating system were made based on the weight of the part and effective casting height. The study clearly shows that the well-designed pressurized gating system has revealed that it plays a significant role in preventing non-metallic casting defects in steel castings, such as sand, gas, and slag. In addition, the '' Spin Trap '' that is recommended to be used in gating systems in ferrous based castings in the literature, was used for the first time in the ÇİMSATAŞ foundry in the steel castings at the end of the runner in the pressurized gating system and the appropriate result was obtained. Computer-aided flow and solidification simulation was used in the design of the gating system containing Spin Trap.
