This episode constitutes Part 2 in the set of 2 that addresses the manufacturing engineering of steel casting mechanical properties, cosmetic appearance, and mitigation of reoxidation inclusions.  Specifically, the 2 parts are Webinar 9, Gating, and this Webinar 10, Risering.  The two webinars address all of the fundamental principles in the manufacturing engineering of a steel casting mold cavity that work together to maximize the most important capabilities of steel castings… and, at their maximum, the best of all metalcastings in structural capability.

Gating of steel castings has 5 necessary fundamentals from physics that govern successful design, but there is latitude for steel casting producers’ personal preferences.  Not so for risering of steel castings, which is very rule-driven and narrow when designed to maximize mechanical properties and cyclic life.

“Risering” (quotes intentional) of steel castings is a system, an orchestrated spectrum, of multiple facets.  This episode defines and illustrates all the facets in that spectrum.  Across the 3 steel casting alloy sub-groups and between the two major mold-making processes (sand and investment), there is consistency in the major “Risering” requirements.  But, there is some important variation among the 3 sub-groups’ differences and the process’s differences.
