        The consumption of various refractories in China is increasing day by day, and the proportion of used refractory materials has reached 45% of the total consumption of refractory. However, the role of so many waste refractory materials in a long time is landfill waste, which not only causes waste of resources, but also causes irreversible pollution to the environment.
        The consumption of various refractories in China is increasing day by day, and the proportion of used refractory materials has reached 45% of the total consumption of refractory. However, the role of so many waste refractory materials in a long time is landfill waste, which not only causes waste of resources, but also causes irreversible pollution to the environment.
        Many countries in foreign countries have already begun to reuse waste refractory materials, even some of which have reached more than 90%. China has also begun to use this research gradually, striving for the development of zero emission.
        But there are many kinds of refractory materials. In the steel industry alone, there are hundreds of waste refractory materials. How can we make better use of the old refractory? Here, we will introduce several common refractory reuse for you.
        1. waste high aluminum brick
        The waste high aluminum brick is crushed to produce refractory mud, and the granular material is used to produce high aluminum castable and plastic, such as castable for rigid cover and plastic for repair.
        2. waste light brick
        After grinding, it can be used to produce light castable or light refractory mud.
        3. castable residual lining
        The castable with high aluminum, corundum, mullite and silicon carbide as aggregate is taken as an example to crush and process into granular material. After iron removal, it can be directly re processed into castable or ramming material.
        4. waste aluminum silicon carbide brick
        The powder can be used to produce refractory mud of the same material and used for building aluminum carbide brick. The granular material can be mixed with new materials to produce aluminum carbide amorphous refractory materials, such as slag ditch castable, slag iron ditch cover, etc.
        5. waste aluminum magnesia carbon brick
        After crushing, it can be added to produce the same material of aluminum magnesium carbon conversion, or can be ground into powder to produce refractory mud for building aluminum magnesium carbon brick.
        6. waste ceramics and electric porcelain
        After grinding into powder, it can improve the wear resistance and thermal shock stability by adding it into the refractory. It can also be added to the aluminum silicon castable. (the working temperature is below 100 ℃
        Above is several common waste refractory reuse, hope to help you!
