A Furan No-Bake Binder System Analysis for Improved Casting Quality

摘要

Traditional cast metal markets have been confronting incessant competition from overseas producers as their lower wage scales and environmental standards reduce their product cost. Many foundries have made changes in their processes reducing air and water emissions. One foundry, Krislur Castomech Pvt. Ltd., Bhavnagar, Gujarat, India, has adopted a newer furan no-bake binder system over a single-part binder system that offers an advantage in terms of strength and environmental concerns by reuse of the sand, which is discussed herein. In this work, grain fineness number and compressive tests are performed and the effect of temperature and resin is measured using the analysis of variance method. Sand topology and defect photographs were taken using a scanning electron microscope to identify sand size and shape. Investigation of the exact defect was performed using energy dispersive spectroscopy. In this work, progress was made in reducing casting defects and improving casting quality.
