Firebrick Features

Own property
1, the chemical composition of : determining the main component of the quality and characteristics of the refractory
2 , bulk density: weight per unit volume , density , indicating good density , high strength may , but probably large thermal conductivity
3 , apparent porosity : not to make a CBN abrasive grit specific request, but manufacturers must be strictly controlled as apparent porosity .
4 , RUL : Also called high-temperature load deformation temperature start , this parameter is very important, high temperature resistance marker material
5, the thermal shock resistance : resistance to sudden temperature change capacity without being destroyed
6 , the compressive strength : bear ( room temperature ) maximum pressure capability
7 , flexural strength : the ability to CBN abrasive grit withstand the shear stress
8 , the linear rate of change : change , also called heavy firing line or call residual line changes , refer to the expansion and contraction of each change in volume occurs at the same temperature change , if every expansion and contraction , we define such a linear rate of change 0
Physical and chemical properties
1, wear resistance :
2 Thermal conductivity : the unit temperature gradient conditions by the rate of heat flow per unit area of ??the material , with a porosity of about
3 , Impact resistance: do not explain it , good impact resistance , service life is long
4 , slag resistance : ability without being destroyed slag erosion resistance at high temperatures
