What is Skimming? - Definition from Corrosionpedia

Skimming stations are the locations inside a basic oxygen process furnace shop where slag is removed from the top of the molten metal bath. The skimming technique is used in . Any blast-furnace slag and slag formed during desulfurization is skimmed off before the iron is charged. Specific ore applications where.

How to calculate the flow of metal exiting the Blast Furnace.

The blast furnace runners essentially consists main trough, metal dam & the slag and metal launders. The design comes in place for calculating the volume required for proper slag metal seperation such that the slag floats above the metal and can be skimmed out. For this you need to know the maximum slag tapping rate.
