Abstract

The invention belongs to the technical field of preparation of refractory materials, and particularly relates to a vibrating material and a preparation method thereof. The method comprises the following steps: carrying out heating reaction on carob bean gum, sodium carboxymethyl starch and the like to prepare a carob bean gum reactant; subsequently, carrying out reaction on sodium alginate, the carob bean gum reactant and the like to obtain a reaction product, and then lyophilizing and pulverizing to obtain a viscous material; mixing the viscous material, silicon dioxide, lime powder and clay to obtain a binding agent; mixing fused magnesia, sintered magnesia and the like in parts by weight to obtain a refractory aggregate; mixing alpha-aluminum oxide micro-powder, diatomite and the like to obtain a powder material; grinding the refractory aggregate, the powder material and an admixture in a mixed manner and mixing with the binding agent to obtain a mixture; filling a mould with the mixture for jolt ramming; finally, baking and demoulding to obtain the vibrating material. The vibrating material has higher sintering strength and good slag corrosion resistance performance, and the service life of the vibrating material is effectively prolonged; meanwhile, the binding agent used by the invention has preferable physical performance, the pollution to molten steel is avoided after sintering, and a clean steel-making requirement can be met.

Description

technical field [0001] The invention belongs to the technical field of refractory material preparation, and in particular relates to a vibrating material and a preparation method thereof. Background technique [0002] The tundish is the intermediate link of the steelmaking production process, and the connection point from intermittent operation to continuous operation. As a metallurgical reactor, the tundish is an important part of improving steel production and quality. The role of the tundish cannot be ignored whether it is for the smooth progress of the continuous casting operation or to ensure the quality of molten steel meets the requirements. Since the working layer of the tundish is directly in contact with the molten steel, it is required that the working layer of the tundish can reduce the inclusions in the molten steel, improve the purity of the molten steel, and also be able to resist the erosion of molten steel and slag, so that the continuous casting and pourin...
