Abstract

509,442. Purifying and refining steel. BRASSERT & CO., Ltd., H. A. (Colclough, T. P.). March 18, 1938, No. 8476. [Class 72] To degasify steel and free it from suspended impurities, small quantities of both aluminium and a fluoride are added to the metal during pouring into an ingot mould. A fluoride of calcium or sodium or both may be used with the aluminium.
