產品描述

Fireclay brick for blast furnace are used in the part of throat, stack, hearth, bottom for a small blast furnace and the stack for a big blast furnace. Fireclay brick for blast furnaces have the following good features:
 High compressive strength in normal temperature
 High ability for anti-abrasion during work
 Low shrinkage degree under high temperature so as to maintaining an integrity of the furnace lining;
 Low apparent porosity and Fe2O3 content to reduce the carbon deposit in the blowhole and avoid the bricks broken in case of expansion
 Seldom melting point settings shape.
