Improving Blind Riser Efficiency

摘要

Providing blind risers with adequate passage to atmospheric air and a hotter top metal front will increase your casting yield and reduce your energy costs. Confronted with escalating raw material and energy costs, ferrous metalcaster AG Anderson, a division of AmeriCast Technologies, London. Ontario, Canada, went back to the basics by re-evaluating sound and simple techniques. Blind risers, or closed risers, are used to feed various casting sections. Although they can be indispensable when feeding certain complex configurations, they are less efficient than open risers. AG Anderson designed a new blind riser system that was able to improve casting yield and reduce labor and energy costs for large carbon and low alloy steel castings.
