LABORATORY CORROSION TESTS OF ROTARY LIMEKILN REFRACTORIES

A modification of the Hugill, Ainsworth, and Green laboratory method for determining the corrosive action of lime on refractories was used to indicate the best refractory for rotary limekilns. An intermediate handmade refractory, two high alumina, two superduty, and two first‐quality, stiff‐mud refractories were tested. It was found that the depth of penetration of the lime attack decreases with an increase in alumina content of the refractory. Better resistance of the 70% aluminous refractories to slagging was indicated by the small‐scale tests which were substantiated by plant‐scale operation.
