Iron LadleHarbisonWalker International Refractory
The iron ladle is often used as a refining vessel to decrease the sulfur content in the molten iron. This desulfurization process is detrimental to the refractory lining due to the turbulence created. Consequently iron ladle maintenance is required on a regular basis. HarbisonWalker International offers two different lining designs for iron Phosphoric acid is an excellent bonding agent for high-alumina refractory products. The bond is formed by reaction of the acid with the alumina in the refractory aggregate yielding an aluminum phosphate cement. Magnesia zirconia and carbon refractories can also be bonded with phosphoric acid.
