Problems solved by technology

With the large amount of discharge and accumulation of magnesium slag, it not only takes up a lot of land resources, but also the magnesium slag flows into rivers and lakes with the rainwater, which has a great impact on crops and the surrounding environment, seriously endangering human health and well-being. crop growth

Abstract

A fireproof castable made of magnesium slag and manganese slag comprises the following raw materials in parts by mass: 20-30 parts of an aggregate, 70-80 parts of a powder and 10-15 parts of an additive; the aggregate is composed of corundum and magnesia alumina spinel; the powder is composed of alpha-Al2O3, a magnesium slag powder, fly ash and a manganese slag powder; and the additive is water-soluble phenolic resin.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a magnesium slag and manganese slag refractory castable. Background technique [0002] Compared with qualitative refractory products, unshaped refractory materials represented by refractory castables have the advantages of short process flow, low production energy consumption and cost, convenient use, wide application range, integrity and good use effect, so they are widely used in the world. It has developed rapidly, and its proportion in the whole refractory material is getting higher and higher. In some countries with advanced refractory technology, the output of unshaped refractories has approached or even exceeded the output of shaped products. For example, the current output of unshaped refractory materials in Japan accounts for about 60% of the total refractory materials; in the United States, it is about 50%; in Britain, Germany, France and other...
