Features of Refractory Bricks for Hot Blast Stove

The characteristics of refractory bricks for hot blast stoves mainly include the following aspects:

High-temperature resistance: the working temperature of the hot blast furnace is generally above 1000 ℃, and the refractory brick has excellent high-temperature stability and can be used stably for a long time in a high-temperature environment without problems such as falling off and cracking.

Thermal shock resistance: During the working process of the hot blast furnace, the temperature changes rapidly, while the refractory brick has good thermal shock resistance and can withstand the stress caused by rapid temperature changes without cracking or cracking.

Wear resistance: The working conditions of hot blast stoves are relatively harsh, and there are erosion and wear of particles, smoke, burning substances, etc., while refractory bricks have excellent wear resistance and can maintain stable surface hardness and strength for a long time.

Chemical erosion resistance: There are acidic or alkaline gases, liquids, and other media in the hot blast stove. These media have a corrosive effect on refractory materials, while refractory bricks have excellent chemical erosion resistance and can be used stably for a long time under the erosion of these media.

Construction convenience: refractory bricks are easy to construct, can be cut and spliced according to needs, and are suitable for thermal equipment of various shapes and sizes.

In general, refractory bricks for hot blast stoves have the characteristics of good high-temperature stability, good thermal shock resistance, good wear resistance, good chemical corrosion resistance, and convenient construction, which can meet the high requirements for refractory materials under the working conditions of hot blast stoves.
