Development of distribution control techniques for burdens in furnace The distribution of the ore and coke layers toward to the direction of the radius is the decisive factor affecting gas distribution and ventilation. When a PCI facility is introduced, it will worsen the ventilation in a furnace due to sulfur instability-creating a factor reducing productivity. In order to improve on this, the distribution of burdens in furnaces must be controlled by controlling the bell-less burden equipment tilting angles, revolutions, and MCG opening inside furnaces. Our goal is to achieve the prevention of heat loss, obtain a reduction of fuel expenses, perform ventilation/reduction/heat exchange functions, and provide a solution for furnace sulfur instability, as well as develop high quality cupola and high productivity by developing the distribution of burdens in a furnace.
