Fire Resistant SK34 Clay Refractory Brick 40MPA Yellow Color

High Acid Resistance Fire Resistant SK34 SK36 SK38 Fire Clay High Alumina Refractory Fire Brick for hot blast stove sical and chemical indexes:

Chemical composition (%)

High Acid Resistance Fire Resistant SK34 SK36 SK38 Fire Clay High Alumina Refractory Fire Brick for hot blast stove is comparable to that of silica bricks, up to 1690~1730℃, but the softening temperature under load is more than 200℃ lower than that of silica bricks. In addition to the high refractory mullite crystals,High Acid Resistance Fire Resistant SK34 SK36 SK38 Fire Clay High Alumina Refractory Fire Brick for hot blast stove also contain nearly half of the low melting point amorus glass se.In the temperature range of 0~1000℃, the volume of High Acid Resistance Fire Resistant SK34 SK36 SK38 Fire Clay High Alumina Refractory Fire Brick for hot blast stove expands uniformly as the temperature rises. The pansion curve is approximately a straight the pansion rate is 0.6%~0.7%, which is only about half of that of silica bricks. When the temperature reaches 1200 ℃ and then continue to rise, its volume will start to shrink from the maximum expansion. The residual shrinkage of High Acid Resistance Fire Resistant SK34 SK36 SK38 Fire Clay High Alumina Refractory Fire Brick for hot blast stove leads to the loosening of mortar joints in masonry, which is a major disadvantage of clay bricks. When the temperature exceeds 1200°C, the low melting point substances in the High Acid Resistance Fire Resistant SK34 SK36 SK38 Fire Clay High Alumina Refractory Fire Brick for hot blast stove gradually melt, and the particles are tightly pressed against each other due to surface tension, resulting in volume shrinkage.Production practice in China has proved that before crushing, high-aluminum clinker is strictly sorted and classified, and stored in tiers.The use of bauxite clinker and combined clay fin grinding method can improve product quality. Competitive Advantage:
