Method for increasing the bulk density of refractory bricks and improving the strength of refractory bricks 1. The increase of the molding pressure of the refractory brick machine increases the density of the refractory bricks. Only by increasing the density of the bricks can high-strength sintered bricks be fired. For refractory bricks with a molding…
Continue ReadingWhat is the fire resistance limit of refractory bricks? The main indicators of refractory bricks are: refractoriness, softening under load, etc. 1. Refractoriness is also called refractory and melting resistance. This performance index characterizes the high temperature tolerance of the object without melting. Refractoriness is not a physical constant, but a technical indicator. Its content…
Continue ReadingWhat are the factors affecting the service life of refractory bricks? 1. Physical action: generally refers to dry and wet change, temperature change, freeze-thaw cycle, etc. These effects will make the volume of refractory brick change or cause the expansion of internal cracks, and gradually destroy the material. 2. Chemical action: including the erosion of…
