IPC: C22B1/16
Filed: 1981-12-17
Abstract: PURPOSE:To produce sintered ores having high cold strength and hot strength by mixing limestone of adequate grain size distributions as sintering raw materials according to the meltability value of raw materials for sintered ores that do not contain linestone powders. CONSTITUTION:Limestone powders having different grain sizes are stored separately, and the limestone powders of adequate grain size distributions are delivered out according to the actually measured values of the meltability value of raw materials contg. no limestone powders from the relations between the quality of sintered ores by each predetermined meltability value of raw materials contg. no limestone powders and the grain size distributions of the limestone powders to be compounded with the sintering raw materials. These limestone powders are mixed as sintering raw materials. The above-mentioned meltability values are expressed by the temp. in the starting stage of melting by heating the raw materials contg. no limestone powders successively. As the grain sizes of the limestone powders diminish moderately, said powders are dispersed uniformly in the sintering raw materials and the air permeability after the decomposition in the calcining zone is degraded, quality is improved and the cold strength and hot strength are improved.
