Dense Castables
The category of refractory castables classified as dense castables represents a
large and diverse group consisting of conventional-type castables and the various
categories of advanced products. For the refractory user, the differences in the
types of advanced castable are important to understand since dense refractory
castables are used as structural components in furnaces and kilns, as primary linings in vessels containing molten metals and slags, in corrosive atmospheres, and
in furnace areas experiencing physical abuse and abrasive conditions. Based on
the intended application, different physical characteristics come into play when
choosing the appropriate castable material.
