Indicators on crucible alumina You Should Know
Wiki Article
Phosphate-bonded high alumina brick is favored in lots of aluminum furnace linings as the phosphate triggers the brick to generally be resistant to wetting and penetration by molten aluminum. Phosphate-bonding also enhances the refractory Attributes by escalating density, decreasing porosity, increasing power, and abrasion resistance.

five. The thermal shock resistance on the high alumina refractory brick is worse than that from the clay brick, which happens to be closely connected to the mineral composition inside the refractory brick. The high alumina brick, such as I, II grade is even worse compared to the III grade high alumina brick.
Right packaging ensures solution integrity through transit and storage. ceramic crucibles for sale Below are market-standard techniques:
High alumina bricks come in standardized sizes and styles, nevertheless personalized dimensions are offered for specialized installations.
Requesting samples and browsing the plant (or verifying by means of online video) is highly recommended for bulk deals.
Only if the changeover for the refractory brick which consists almost totally of corundum firebrick, that's to say, when the Al2O3 written content is over 95%, high toughness at high temperature is clearly improved.
Iron and Steel Field: Ideal for blast furnaces, hot blast stoves, and ladles because of their outstanding thermal steadiness and resistance to slag erosion.
