Insulation Fireclay Bricks Series
description
Insulation fireclay bricks are a kind of high temperature insulation refractory material. It is made of refractory clay clinker as raw material, plastic clay as binder, adding an appropriate amount of combustible or foaming agent, pressed brick press molding, and then sintered.
Features
It has the characteristics of high strength, good thermal shock resistance, small change of permanent linear, small thermal conductivity, good insulation performance.
Application
Widely used in metallurgy, machinery, ceramics, chemical and other thermal equipment and industrial furnace lining and layer.
