<p>ABSTRACRT OF THE DISCLOSURE A sand cooler control system for a sand casting foundry system incorporates a cooling system positioned downstream of the shakeout station where castings are separated from the hot sand. The amount of cooling fluid utilized in the cooling process is controlled by a digital system responsive to the total heat (BTU) content of the sand as determined by a combined function of sand temperature and volume. The temperature and volume parameters are determined by non-contact sensors which take the form of an infrared sensor and sonic sensor, respectively.</p> |
