When blended with different amounts of magnesia and higher qualities of fused alumina these brick attributes give Price-productive refractory efficiency for that steel ladle.
two. For your refractory brick with the Al2O3 information below 70%, the refractoriness beneath load relies on the quantitative proportion of crystal phase and liquid stage, it raise with the rise in the number of mullite.
The reduction of impurities written content is favor of enhancement of slag resistance. Meanwhile, the improvement of refractory brick density, the reduction of porosity, They are really the productive measure to improve the slag resistance.

three. For that mullite- corundum refractory brick with the AL2O3 information of 70% ~ 90%, the material of AL2O3 raises, but the improvement of refractoriness less than load is not carbon bonded silicon carbide crucible really evident. That is a result of the partial softening in the mullite crystals at high temperature as well as a slight boost in the quantity of flux impurities that interact with the mullite crystals.
A phosphate chemical addition reacts with free of charge alumina inside the brick combine to type an aluminum ortho-phosphate chemical bond in the course of medium temperature curing. Firing a phosphate-bonded brick to higher temperatures leads to a composition that has both phosphate and a ceramic bond.

Only once the transition towards the refractory brick which is composed almost solely of corundum firebrick, that is to convey, in the event the Al2O3 information is in excess of 95%, high power at high temperature is clearly enhanced.
Iron and Steel Market: Perfect for blast furnaces, scorching blast stoves, and ladles due to their great thermal balance and resistance to slag erosion.
We specialize in producing high quality high-temperature alumina bricks tailor-made to meet the requires of varied industries. Our items are crafted making use of Sophisticated technologies and high-quality Uncooked components, ensuring Fantastic functionality and durability.
