SILICA COMPLIANCE SEMINAR VIDEO
This series of videos will help metalcasters understand the new regulations on respirable silica dust. These videos will give you the best chance to learn how to comply with the new regulations for the good of your business.
The presentations provide a deep dive on the details on the new law, measurement requirements, sampling methodology, regulated areas, medical surveillance, respira- tors, and how to develop a written compliance control program.
Also included are PDFs of Power- Point presentations given during the seminar that highlight specifics about the topics covered.
AFS DEVELOPING MODEL FOR INVESTMENT CASTING
The model is hoped to predict the thermo-mechanical properties of silica based investment shells.
Problem: In steel casting, differ- ent shell pre-firing temperature and time profiles result in different amounts of silica devitrification, affecting the thermo-mechanical properties of the shell molds.
Research: Investigators will study the thermal properties of investment shells molds during solidification. Data from experiments and simula- tions can help determine optimal pre-firing temperature/time profiles and develop a computer model to predict shell properties. The proj- ect is being conducted at Missouri University of Science and Technol- ogy and monitored by the AFS Investment Casting Committee (4L).
