Abstract
The invention relates to a novel high strength refractory brick and a production method thereof. The novel high strength refractory brick comprises, by weight, 50-70 parts of corundum, 20-40 parts of mullite, 1-10 parts of first grade clay, and 1-10 parts of an ultrafine powder binder, and also comprises arched CrNi steel fibers, and 100Kg of the CrNi steel fibers are added to 1m<3> of the refractory brick. Compared with refractory bricks in the prior art, the novel high strength refractory brick provided by the invention has the advantages of high refractoriness and high flexural strength.
