Refractory erosion in iron melting is seldom attributable to mechanical wear. Erosion generally is the aftermath of slag’s chemical attack – chemical reactions between slag and refractory – producing reaction byproducts that enter the slag. The overall effect is refractory’s effective protection layer, the thickness of the refractory lining, is continually eaten away, eventually leading […]

Molten metal demands a lot of attention, to ensure purity while it is in the furnace and stability as its filling the mold. In between time, when the furnace is tapped or poured out, the metal must be monitored to ensure its quality is not degraded – and there is technology to assist with that. […]
