Abstract

Se describe una placa de acero eléctrico no orientado de bajo costo con un contenido de aluminio extremadamente bajo, cuya placa comprende los siguientes elementos químicos en porcentaje en masa: 0.003 % o menos de C, 0.1 %-1.2 % de Si, 0.1 %-0.4 % de Mn, 0.01 %-0.2 % de P, 0.003 % o menos de S, 0.001 % o menos de Al, 0.003 %-0.01 % de O, 0.003 % o menos de N, y 0.005 %- 0.05 % de Sn, con la condición Si2/P: 0.89-26.04 que se satisface. Además, se describe adicionalmente un método de fabricación de la placa de acero eléctrico no orientado. El método comprende las etapas de: (1) fundición; (2) colada continua; (3) laminado al calor: en donde una placa laminada al calor se somete a remojo y conservación del calor por medio del calor residual de las bobinas de acero laminado al calor, en lugar de someterse a un tratamiento de normalización o recocido en horno recubierto después del embobinado; (4) laminado en frío primario; y (5) recocido continuo. En la placa de acero eléctrico no orientado de la presente invención, se usan ingredientes químicos y diseños de proceso razonables, y la placa de acero eléctrico no orientado no solo tiene una excelente economía, sino que también tiene propiedades de alta inducción magnética y baja pérdida de hierro.
