refractory selection for a blast furnace trough
Principles for Blast Furnace Refractory Lining Inspection
Blast furnaces are lined by carbon and graphite refractory bricks to protect the integrity of the vessel. Carbon and graphite refractories are primarily used for blast furnace linings because of their high temperature conductivity and their ability to reduce the heat load by moving the excessive heat to the shell where the heat can be
