Abstract
Preferentially castable or precast shapes like EAF delta, tundish furniture, and porous plus have a significant share among all monolithic during steelmaking. Several classic considerations are required for the castable composition design to improve performance: on-site casting in vessels or installed precast shapes. While the castable composition is a concern, the variation of cement content influences the high-temperature performance as low CaO content; thus low porosity facilitate better slag corrosion resistance, hot strength, high abrasion, and thermal shock resistance. The influence of aggregates, binders, deflocculant, and particle grading are correlated with flowability behavior and mechanical response to design the suitable precast shape. Anchoring materials, shape, and preferred position result in the cumulative strength of the on-site castable lining, and such an issue has been covered systematically. Different classes of purging plug design, installation, maintenance, clogging, corrosion, and the influence of their operational parameters ensure the purging plug selection that eventually reduces the open-eye formation during secondary steelmaking.
