✦ Synopsis

The dry mixture that results from the blending of iron-rich oxide dust and other such wastes carbonaceous material is heated to release the volatiles with agglomeration. It is subsequently loaded into a preheated furnace with rotary hearth and heated for 5-12 min at 2150-2350°F for smelting and discharging the metalized product suitable for recycling. The dry mixture is briquetted at >lO,OOO psi, and the briquettes are smelted at the nominal CO/CO: ratio of 2-5 for the reduction of metal oxides. The metalized Ferich briquettes are suitable for recycling to the steelmaking plant. 97103134 Some aspects of pneumatic injection with particular reference to the design of dischargers and lock feeders
