Direct pouring system design and optimization in steel castings
Main Article Content
Abstract
The aim of this study is to establish a correlation between various version direct pouring systems for steel castings in industrial conditions. In the study, a computer-aided design solid modeling program was used in the design of the kalpur direct pouring system, non-filter bottom direct pouring system, and filtered direct pouring system for steel castings. The flow and solidification simulation of the kalpur direct pouring system and the non-filter bottom direct pouring system of the casting part was made in 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 steel castings, such as sand, gas, and slag. In addition, it has been revealed in the study that the non-filter bottom direct pouring system prevents non-metallic casting defects in steel castings such as the kalpur direct pouring system. Kalpur direct pouring system is recommended to be used in ferrous based castings by FOSECO, was used for the first time in the ÇİMSATAŞ foundry in the steel castings and the appropriate result was obtained.
