Desulphurization of Liquid SteelIspatGuru
Jul 30 2016 · Use of dolomite or other basic refractory lined materials are to be used for efficient desulphurization. After tapping of the liquid steel from the primary steelmaking furnace the amount of slag carried over is not known. Another unknown parameter is the loss of aluminum (Al) during tapping which results in different amounts of Al2O3 in the slag.

What Are the Reasons for Refractory Brick Erosion WAM
In severe cases the furnace body will be damaged. Chemical attack is also divided into furnace gas attack and oxidative attack. Sometimes there is mutual erosion between refractory materials. Just like the mixing of basic refractory bricks and acid refractory materials they will be electrochemically attacked by refractory bricks.

Foundry ManualPart 4Maritime
In an emergency an oil-fired crucible furnace can be used to melt the high-carbon high-silicon cast irons. This practice however is slow and permits only one or two heats per crucible and results in reduced refractory life in the furnace. Because of its high pouring temperature cast iron is difficult to melt in an oil-fired crucible furnace.
