ROASTING-FREE REFRACTORY MATERIAL Russian patent published in 2000 - IPC

FIELD: refractories industry, more particularly manufacture of refractory products for lining of heat assemblies operating at temperature up to 1400 C. SUBSTANCE: roasting-free refractory material comprises as hydrotation components, binding agent, lime and tripoli, as ceramic structure forming components, spent sulfur production catalyst and pyrite cinders and as filler fireclay having fractions, wt.%; 0-0.63 mm fractions, 25; 0.63-1.25 mm fractions, 12.5; 1.25-2.5 mm fractions, 62.5; ratio of components is as follows, wt. %; spent sulfur production catalyst, 20.0-22.1; pyrite cinders, 5.3-6.8; tripoli, 5.6-7.2; lime, 6.0-6.68; fireclay, 57.5-62.5. EFFECT: reduced pressing pressure, lower price and no ecological problems are involved, since two types of large tonnage waste products are utilized. 3 tbl
