What is Ladle Covering Agents:<\/strong><\/p>\n

Ladle covering agents<\/strong><\/a> are functional materials used to cover the molten steel surface in ladles during steelmaking, with core functions including:<\/p>\n

Thermal insulation: Reducing heat loss to maintain pouring temperature stability;
\nAnti-oxidation: Isolating air to prevent secondary oxidation of molten steel;
\nInclusion adsorption: Purifying molten steel through slag-metal interface reactions;
\nImpact buffering: Mitigating splashing and slag entrainment during steel pouring.<\/p>\n

\"\"<\/p>\n

Typical Components of Ladle Covering Agents:<\/strong><\/p>\n

Their typical components are dominated by Al\u2082O\u2083, SiO\u2082, and CaO, supplemented with heating agents (e.g., Al powder) and lightweight thermal insulation materials (e.g., float beads).<\/p>\n

Classified by function of Ladle Covering Agents:<\/strong><\/p>\n

Heat-generating type: Compensates for temperature loss via exothermic reactions, suitable for long-time casting or low-temperature steel grades;
\nInsulating type: Uses low thermal conductivity materials as the matrix, focusing on heat preservation with lower costs;
\nComposite type: Integrates both heat generation and insulation, adapting to complex process requirements.
\nPerformance requirements: Melting point <1200\u00b0C, low viscosity, basicity (CaO\/SiO\u2082) 1.0\u20131.5, and rapid slag formation capability.<\/p>\n
