Способ плавки чугуна в вагранке, включающий загрузку шихты, ее плавление, перегрев чугуна, накопление его в копильнике и выпуск через металлическую ленту в ковш, отличающийся тем, что, с целью устранения "замерзания" металлической летки преимущественно в первоначальный период плавки, перед накоплением чугуна нужной марки предварительно обогревают летку жидким чугуном, содержащим 3,5 - 4,4% C, 0,9 - 2,2% Si, 0,4 - 2% Mn, объемом, равным
Figure 00000001
где dк - диаметр копильника, м, причем обогрев летки ведут одновременно с подачей в жидкий чугун кислорода, при этом подачу кислорода осуществляют в предлеточное пространство копильника по трубопроводу, смонтированному в футеровки дверки копильника.
A method of melting cast iron in a cupola, including loading the mixture, melting it, overheating cast iron, accumulating it in a piggy bank and releasing it through a metal strip into a ladle, characterized in that, in order to eliminate the “freezing” of the metal notch mainly during the initial melting period, before the accumulation of cast iron of the desired brand, the notch is preheated with molten iron containing 3.5 - 4.4% C, 0.9 - 2.2% Si, 0.4 - 2% Mn, with a volume equal to
Figure 00000001
where d k is the diameter of the piggy bank, m, and the holes are heated simultaneously with the supply of oxygen to the liquid cast iron, while the oxygen is supplied to the pre-storage space of the piggy bank through a pipe mounted in the lining of the piggy bank door.
