Brick fire-resistant shamotny in Ukraine

Fire-resistant brick — the brick intended for internal facing of furnaces, fireplaces, flues and chimneys. The fire-resistant bricks which were in the use are called fire-resistant scrap and are used in processing.

Fire-resistant bricks serve for fire isolation. Fire-resistant bricks form a cover which protects a furnace laying from direct fire or the heated coals therefore has to distinguish them:

• heat resistance — the brick has to maintain long heating to temperature of 1000 °C without loss of durability
• high thermal stability — the brick has to maintain without loss of durability many raskalivaniye and ostyvaniye
• low heat conductivity — the brick has to keep warmly in the furnace or a fireplace

Fire-resistant bricks serve for preservation of heat. Furnaces and fireplaces create a cosiness in the house — they accumulate and gradually give heat, maintaining the pleasant temperature therefore has to distinguish fire-resistant bricks in the house:

• big thermal inertia — the brick has to heat up long and cool down slowly
• big thermal capacity — the brick has to accumulate a lot of heat
