Masses based on calcined and granulated dolomite for coating vessels for containing liquid iron and steel. (Didier-Werke A.-G., Ger.). Belg. BE 861684 31 Mar 1978, 11 pp. (French). (Belgium). CODEN: BEXXAL. CLASS: IC: C04B. PRIORITY: GB 76-51683 10 Dec 1976. DOCUMENT TYPE: Patent CA Section: 55 (Ferrous Metals and Alloys) Section cross-reference(s): 57 The compns., for lining vessels which receive molten Fe or steel, consist essentially of calcined granulated dolomite, a natural triglyceride oil (1-6%), and a ground inorg. binder (2-6%). Thus, a suitable compn. is made by spraying dolomite with soybean oil 4 and mixing the product with ground Na3PO4 [7601-54-9] 2 and ground Na silicate [1344-09-8] 0.5% by wt. of the final anhyd. product. Dried paper pulp may also be added. The compns. can be stored without special precautions against hydration.
