Abstract
La presente invención se refiere a una composición de materia que es una suspensión para aplicación a tira de acero al silicio, como un agente para impedir que vueltas adyacentes queden adheridas entre sí durante el recocido subsecuente de una bobina de dicha tira, la suspensión consistiendo principalmente de óxido de magnesio y agua, la mejora que comprende añadir a la suspensión una cantidad de hasta 1 por ciento en peso de heptahidrato de sulfato de magnesio y aproximadamente 1 a 12 por ciento en peso, basado en el óxido de magnesio presente y valores típicos de perdida a la calcinación obtenidos despues del secado, de polvo de metal de magnesio, efectivas para impedir el desarrollo de defectos de revestimiento sobre la superficie del acero durante el recorrido, en donde el polvo de metal de magnesio se define dentro de una escala de tamaño de malla de menos 50 a menos 320.
