Automatic Control of Foundry Molding Sand Constituents

Abstract

<p>Some of the advantages and problems involved in the conversion from manual to automatic control of foundry molding sand constituents are discussed. The principal problem is that a transducer capable of monitoring each additive content is currently not available. The results of a search for an analytical technique suitable for such a transducer are presented. Of the numerous analytical methods reviewed, the multiparameter electrical technique, appeared to be most advantageous at the time that the survey was made. A description of its experimental evaluation is given. While a suitable transducer is not positively identified, guidelines for further work are suggested.</p>
