Low cement castables use calcium aluminate cement as a binder, and castables with a CaO content of less than 2.5% are generally called low-cement castables.
High density
High intensity
Low porosity
Low wear
Resistant to penetration and corrosion
Low cement refractory castables mainly include three types: high alumina refractory castables, mullite refractory castables, and corundum refractory castables. Low cement castables are used in heating furnaces, soaking furnace linings, tundish linings, electric furnace roofs, tap trenches, RH lift pipes, spray guns, etc.
