Abstract

The bell-less blast furnace tops of the type Wurth or Vitkovice, i.e. the bell-less tops equipped with a rotary chute, enable effective management of the blast furnace burdening. The calculations using the sufficiently true mathematical model make possible to reduce the number of difficult and expensive experiments to obtain the needed management data. The motion of burden materials in the bell-less top can be formally separated into several phases. One of the crucial phases is just the motion of burden materials at the rotary chute of the bell-less top.
