La separaci\u00f3n de estas impurezas determina la calidad del acero. La escoria de refinaci\u00f3n act\u00faa como un \"dializador de sangre\" en la purificaci\u00f3n del acero fundido.<\/p>\n<p>I. \u00bfQu\u00e9 es la escoria de refinaci\u00f3n de acero? La escoria de refinaci\u00f3n es un material auxiliar metal\u00fargico derivado de piedra caliza, bauxita, etc., mediante sinterizaci\u00f3n o prefusi\u00f3n. Se a\u00f1ade a la cuchara durante los procesos de refinaci\u00f3n, como en los hornos LF y RH. Los sistemas de escoria m\u00e1s comunes son CaO-CaF\u2082 y CaO-Al\u2082O\u2083, caracterizados por bajos puntos de fusi\u00f3n y alta basicidad.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-88232\" src=\"https:\/\/keruiref.com\/wp-content\/uploads\/2026\/05\/Steelmaking-Refining-Slag-1.jpg\" alt=\"\" width=\"650\" height=\"355\" srcset=\"https:\/\/keruiref.com\/wp-content\/uploads\/2026\/05\/Steelmaking-Refining-Slag-1.jpg 650w, https:\/\/keruiref.com\/wp-content\/uploads\/2026\/05\/Steelmaking-Refining-Slag-1-300x164.jpg 300w, https:\/\/keruiref.com\/wp-content\/uploads\/2026\/05\/Steelmaking-Refining-Slag-1-18x10.jpg 18w\" sizes=\"auto, (max-width: 650px) 100vw, 650px\" \/><\/p>\n<p>Seg\u00fan el m\u00e9todo de producci\u00f3n, se divide en tres categor\u00edas: tipo mixto (mezcla directa, bajo costo pero poca uniformidad); tipo sinterizado (sinterizaci\u00f3n a baja temperatura, composici\u00f3n m\u00e1s uniforme pero propensa a la absorci\u00f3n de gases); y tipo prefundido (fusi\u00f3n completa, alta pureza, r\u00e1pida formaci\u00f3n de escoria, pero alto costo).<\/p>\n<p>II. Mecanismo de purificaci\u00f3n de la escoria de refinaci\u00f3n Se basa en un mecanismo dual de \u201cpurificaci\u00f3n qu\u00edmica + aislamiento f\u00edsico\u201d.<\/p>\n<p>Desulfuraci\u00f3n y desoxidaci\u00f3n: El CaO es el componente principal para la desulfuraci\u00f3n. Tras la formaci\u00f3n de escoria blanca (FeO &lt; 1%), el azufre se convierte en CaS, logrando una desulfuraci\u00f3n profunda. La tasa de desulfuraci\u00f3n puede alcanzar m\u00e1s del 70% con una basicidad de 3,4 a 4,2.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-88233\" src=\"https:\/\/keruiref.com\/wp-content\/uploads\/2026\/05\/Steelmaking-Refining-Slag-2.jpg\" alt=\"\" width=\"650\" height=\"380\" srcset=\"https:\/\/keruiref.com\/wp-content\/uploads\/2026\/05\/Steelmaking-Refining-Slag-2.jpg 650w, https:\/\/keruiref.com\/wp-content\/uploads\/2026\/05\/Steelmaking-Refining-Slag-2-300x175.jpg 300w, https:\/\/keruiref.com\/wp-content\/uploads\/2026\/05\/Steelmaking-Refining-Slag-2-18x12.jpg 18w\" sizes=\"auto, (max-width: 650px) 100vw, 650px\" \/><\/p>\n<p>Adsorci\u00f3n de inclusiones: La escoria de alta basicidad y baja viscosidad puede adsorber eficazmente inclusiones no met\u00e1licas como Al\u2082O\u2083 y SiO\u2082.<\/p>\n<p>Protecci\u00f3n contra la escoria espumada: Cubre el acero fundido, lo a\u00edsla del aire para evitar la oxidaci\u00f3n secundaria, protege el revestimiento del horno y mantiene el calor.<\/p>\n<p>III. C\u00f3mo seleccionar cient\u00edficamente la escoria de refinaci\u00f3n<br \/>\nConsidere el tipo de acero, el proceso y la protecci\u00f3n ambiental. Una basicidad de 2,5 a 3,0 permite obtener buenos resultados generales. Para acero al carbono simple y acero para la construcci\u00f3n, se pueden seleccionar tipos sinterizados o mixtos de menor costo; para aceros de alta calidad, como el acero para la industria automotriz y el acero el\u00e9ctrico, se deben utilizar tipos prefundidos de alta basicidad.<\/p>\n<p>IV. Transformaci\u00f3n verde: Una nueva direcci\u00f3n para la escoria de refinaci\u00f3n libre de fl\u00faor.<br \/>\nLa escoria tradicional suele contener fluoruro de calcio (CaF\u2082) para reducir su viscosidad, pero esto genera gas fluoruro de hidr\u00f3geno (HF), altamente t\u00f3xico, que corroe el revestimiento del horno y contamina las masas de agua. Wuhan Iron and Steel (WISCO) y otras empresas han desarrollado una escoria de refinaci\u00f3n sin fl\u00faor, que no corroe los equipos, se forma r\u00e1pidamente y logra un equilibrio entre la protecci\u00f3n del medio ambiente y el rendimiento.<\/p>\n<p>Con el creciente \u00e9nfasis en la producci\u00f3n de acero ecol\u00f3gico, las nuevas escorias de refinaci\u00f3n, eficientes, de bajo costo y respetuosas con el medio ambiente, se est\u00e1n convirtiendo en la norma en la industria, brindando un s\u00f3lido respaldo para la producci\u00f3n de acero de alta gama.<\/p>\n<p>Kerui Refractory suministra diversos tipos de escorias de refinaci\u00f3n.
