Foundry Practice 266

Welcome to our 266TH EDITION of our in-house technical journal of Foundry Practice. The journal, now in its 87th year, is designed to inform foundrymen of Foseco’s latest technologies and application techniques to ensure the ongoing advancement of our customer’s foundry practice.
This edition highlights a new technology in non ferrous metal treatment and presents fundamental research from our R&D teams on thermally efficient crucibles and best practice filter application techniques for vertically parted moulding lines.

Thermally-efficient crucible technology

Calculating the energy savings from the deployment of thermally efficient crucibles in the foundry is extremely difficult to do due to the number of influencing variables affecting performance and the problems of monitoring the energy consumption of individual melting and holding furnaces. Through the development of mathematical models, the benefits of using thermally efficient crucibles become clear and represent an important and underused source of value for the foundryman.

SMARTT – defined hydrogen levels after aluminium rotary degassing

The SMARTT degassing system is the latest advance in automated aluminium melt quality control. The SMARTT degassing process takes ambient conditions into account when calculating the optimum treatment parameters to facilitate the achievement of constant melt quality. Full data logging provides vital information for quality control.

Best practice filter application techniques

The deployment of ceramic foam filters in gating systems of mass produced safety critical parts has become standard practice in the modern foundry. However, the performance of the filter and the benefits achieved in inclusion removal, turbulence control and lower scrap rates are strongly influenced by the correct placement of the filter and the design of the filter print.
