Detailed explanation of 7 types of refractory materials for trough tapping structures

When the electric furnace taps steel, the furnace body tilts to a certain angle (usually 45°) in the tapping direction. The molten steel flows through the tapping trough and enters the ladle. In addition to guiding the molten steel, the tapping trough also prevents the molten steel from scattering. , protect molten steel and reduce …
