Low-cost fire-resistant pouring material and method for making same

Abstract

The present invention discloses a fireproof pouring material with low cost, which takes the low-grade fireproof waste material residue such as waste clay brick, waste wonderstone brick and waste aluminum brick and so on as the raw materials, water glass as the binding agent, fluoriin sodium silicate as the accelerating agent. By using of pouring material, the fireproof precast block can be prepared. The fireproof pouring materials can be used in the heat stove bushing including metallurgy residue pot separated container, middle enveloping level and heat stove bushing and so on. The fireproof pouring material is not only with high refractoriness and large intension, but also can decrease the cost of the residue pot. The present invention plays very importance to saving fireproof material resource, decreasing the discharge of the fireproof material after being used, improving the environment and circulating the economy and so on.

Description

technical field [0001] The invention relates to the recycling of used refractory materials, in particular to a low-cost refractory castable and a preparation method thereof. Background technique [0002] Iron and steel enterprises will produce a large amount of steel slag in daily production, and the steel slag produced by steelmaking is poured into the slag tank. The steel slag is transported to the slag treatment field or workshop by the slag tank, and then the subsequent slag treatment is carried out. The timely cleaning and reuse of steel slag plays an important role in the smooth production and economic benefits of steel mills, and is conducive to the sustainable development of enterprises and the country. Therefore, the slag tank containing steel slag is an indispensable important container for steel mills to maintain normal production. Since the steel slag often contains residual steel, the steel slag poured from the slag tank becomes a large slag mound, which is di...

Problems solved by technology

Since the melting point of scrap steel slag, slag and gypsum is very low, it is easy to be melted by the poured high-temperature steel slag and combined to form a whole, which cannot achieve the purpose of dividing the steel slag block

Chinese Patent Publication CN2465840 discloses a device for setting one or more layers of grids in the slag tank. The grids are assembled from prefabricated plates made of cement, steel slag or refractory materials, but it does not provide And the specific type of refractory material used
