Abstract

La presente invención se refiere a un método para la comprobación y control en la línea de un horno de arco eléctrico en la fabricación de acero, utilizando un sistema procesador de datos para suministrar la información de control, para controlar el horno de arco eléctrico, que comprende los pasos de: (a) comprobar los datos eléctricos procedentes del horno de arco representativos de la condición eléctrico y energía eléctrica suministrada al horno (b) calcular un factor de estabilidad de los datos eléctricos de acuerdo con el algoritmo siguiente; factor de estabilidad 200- Reactancia de operción * 100/Reactancia de Corto Circuito, en donde; Reactancia de Operación Megavares Medidos/3* Corriente de Electrodo (calculada) elevado al 2; Corriente de electrodo (calculada) MVA*/3 elevado al 1/2 * V primario; La reactancia de corto circuito Constante la cual es derivada sumergiendo el electrodo en el baño de acero líquido y desarrollando el siguiente cálculo; Reactancia (a corto circuito) Megavares/3*Corriente elevado al 2* N elevado al 2 en donde: Megavaresenergia primaria medida; Corrientecorriente primaria promedio medida; Nrelación de voltaje de transformador; (c) comparar dicho Factor de Estabilidad calculado con un factor de Estabilidad prestablecido para dicho horno de arco que corresponde a un periódo dado de operación de horno y (d) introduciendo materia prima en el horno cuando el Factor de Estabilidad calculado esté por abajo del nivel pre-establecido por dicho periódo de operación de horno, para elevar el Factor de Estabilidad a dicho nivel pre-establecido.
