The provided hard Refractory Fireclay Brick is fabricated from unfired hard-headed bond clay and fireclays fired recalcitrant clay or comparative grog materials. This has two primary parts to be specific 18- 44 % alumina and 50- 80 % silica. The assortment of clays and assembling procedures permits the generation of various block types proper to specific applications. In addition, the helpfulness of our product is high because of the existence of mineral mullite that frames amid firing. It is portrayed by high hard-headedness and low heat extension.
Production of Product:
Our solid Refractory Fireclay Brick basically comprises of hydrated aluminum silicates alongside minor ratio of different minerals. It is the most well-known individual from this group. At elevated temperature, the consolidated water is driven off, and the buildup hypothetically comprises of 54.1% silica and 45.9 % alumina. Nevertheless, even the most flawless clays contain small measures of different constituents, for example, mixes of lithium, potassium, sodium, titanium, magnesium, calcium, iron and typically some free silica. The absolute amount of the fluxing specialists that bring down the dissolving point ought to be at a dimension of 5-6 % optimum.

1) Refractory Fireclay Brick for Blast Heater : This sort of firebricks is produced with fireclay as the material to construct coating of the heater. It likewise can be utilized to construct heater throat, heater stack, heater hearth and heater base of small blast heater, and heater stack of vast heaters.
2) Refractory Fireclay Brick for Hot Blast Stove : The bricks are made of fireclay as a material to make hot blast stove. This sort of bricks are essentially utilized in insulating wall, regenerative chamber and more areas, which have great heat shock safety, high recalcitrance under low and load creep deformation.
