Refractory brick selection tips
Refractory brick The use of kilns is inseparable from refractory bricks, but if the details of refractory bricks are not properly handled during the masonry process, it will bring a lot of trouble to the later use. Therefore, when building refractory bricks, pay attention to the angle and also Pay attention to the location, as far as possible, choose refractory bricks with good refractory material performance, and there will be no thermal expansion and contraction and chemical reactions during use, as described in detail below. How to choose refractory brick: 1. Resist the effect of high temperature heat load, not softening or melting. Refractory bricks are required to have a fairly high degree of refractoriness. 2. Resist the effect of high temperature heat load, the volume does not shrink and only uniform expansion. It is required that the material has high volume stability, the residual shrinkage and residual expansion should be small, without crystal form transformation and ...
