Abstract

Способ выпуска шлака из стационарной печи включает следующие операции: формирование на стационарной печи выпускного отверстия для удаления из нее шлака, забивка указанного выпускного отверстия глиной или глинистой массой, пробуривание летки через глину или глинистую массу в выпускном отверстии для формирования летки, обеспечивающую возможность вытекания шлака, причем диаметр летки, пробуренной через глину или глинистую массу, значительно меньше ширины выпускного отверстия, и управления потоком шлака через летку путем регулирования размера летки.The method for discharging slag from a stationary furnace includes the following operations: forming an outlet on a stationary furnace to remove slag from it, plugging said outlet with clay or clay mass, drilling a tap hole through the clay or clay mass in the outlet to form a tap hole, allowing the slag to flow out, moreover, the diameter of the tap hole drilled through the clay or clay mass is significantly less than the width of the outlet, and controlling the flow of slag through the tap hole by adjusting the size of the tap hole.
