2022-058 – Applications of Chromite Sizing for Casting Production

Saturday, April 23^rd, 2022 at 1:30pm
Session Room B231-232

Kelley Kerns

This discussion will review the impact that Chromite Sizing has on castings to foundry customers. Mined sources of Chromite vary in unique chemistry based upon the geographical location of the ore. This chemistry influences the shape and sizing of the product that impact the screen distribution. This screen distribution impacts many elements of foundry application. These include the casting surface appearance, binder level requirements and others.

2022-105 – Effect of Phenolic Urethane Resin Ratios on Ambient and High Temperature Mechanical Properties

Saturday April 23^rd, 2022 at 3:15-4:45
Session Room B244-245

Brodie Biersner

Understanding the influence that resin ratio has on phenolic urethane no-bake in both room temperature and high temperature physical properties. Show how ratios can help the foundry optimize costs, and target certain performance attributes associated with the production of mold/cores. Show the effect resin ratios have on the mechanical properties of core sand.

2022-095 – Influence of Refractory Coating Formulation on the Surface Roughness of A356 Aluminum Castings Produced by 3D Printed Sand

Monday, April 25^th, 2022 at 1:30pm
Session Room B242-243

Daniel Cygal & Nathaniel Bryant (University of Northern Iowa)

HA International and the University of Northern Iowa investigated the improvement of the surface roughness of A356 aluminum castings through the use of refractory mold and core coatings in 3D (additive manufacturing applications).
