Low Porosity Industrial Kiln 1750C Refractory Fire Clay Bricks Heat Resistant
Fire Clay Bricks 1400 degree heat proof bricks is made from clinker clay by mixing, forming, drying, sintering and machine pressing moulding with good resistance to corrosion and abrasion, good thermal shock resistance, good spelling resistance, high mechanical strength, good volume stability under high temperature.
Clay brick is a common kind of firebrick, also known as sintering brick.Refers to the alumina content of 30%~40% aluminum silicate made of clay products.Clay brick is composed of 50% soft clay and 50% hard clay clinker in accordance with certain particle size requirements.After forming and drying, it is fired at 1300~1400℃.The raw material of clay brick is clay, shale, coal gangue and other powder materials, and the mineral composition is mainly kaolinite (Al2O3 2SiO2 2H2O) and 6%-7% impurities (oxides of potassium, sodium, calcium, titanium and iron).
