The Al2O3 content of the Yellow Low Bulk Density 1350C Fire Clay Bricks Insulating
Refractory Brick refractory bricks used For steel Furnace is from 30-48%.During the manufacturing,first mix the clay chamotte
with refractory clay powder,then prepared with clay aggregate into
dry mud,high pressure molding,sintering at about 1400C.Under high
temperature,the Yellow Low Bulk Density 1350C Fire Clay Bricks Insulating
Refractory Brick refractory bricks used For steel Furnace show weakly acidic,and the ability of resistance to alkaline slag
erosion is poor,but with the increase of the content of Al203,the
thermal stability of Yellow Low Bulk Density 1350C Fire Clay Bricks Insulating
Refractory Brick refractory bricks used For steel Furnace is better than silica brick, magnesia brick and so on.
Yellow Low Bulk Density 1350C Fire Clay Bricks Insulating
Refractory Brick refractory bricks used For steel Furnace is made from clinker clay by mixing, forming, drying, sintering and
matching characterized by good resistance to corrosion and
abrasion, good thermal shock resistance, good spelling resistance,
high mechanical strength, good volume stability under high
temperature.
Yellow Low Bulk Density 1350C Fire Clay Bricks Insulating
Refractory Brick refractory bricks used For steel Furnace is made of local top grade fireclay materials under the high
temperature according to the lasted national standard, which
possesses even bulk density, high strength, low thermal
conductivity and low impurity.
Advantage
1. Good resistance to corrosion and abrasion,
2. Perfect thermal shock resistance,
3. Good spalling resistance,
4. High mechanical strength,
5. Good volume stability under high temperature,
6. Excellent thermal performance, and acid resistance.
Application:
1) Cement and other building materials industry kiln back
insulation;
2) Petrochemical, metallurgical, ceramics, glass industry, the
furnace lining insulation;
3) Heat treatment furnace backlash insulation;
