A direct reduction technology for rotary kiln features that the adhesive prepared from humate and bentonite is used for sphericizing, and the resultant spheres are heated by a vertical furnace as external heater. Its advantages are high reduction speed, low cost, long service life. High compression strength of sphere (1000-1500 N), and low requirement to S content (1%)

either partial reduction of iron or total reduction of iron. One partial reduction and one total reduction example are discussed below. a. Kerr-McGee process The Kerr-McGee process is shown in Figure 4. It involves partial reduction of ilmenite in a rotary kiln. The

Coal Based Direct Reductionrotary Kiln Process Ispatguru. Feb 14 2017 the process of direct reduction is carried out in a rotary kiln where the operating temperatures are maintained in a range from 1000 deg c to 1100 deg c the product of the kiln dri and char mix is then cooled in a rotary cooler with external water cooling system the products of the kiln is screened and magnetically separated

The reduction flue gas, containing CO 2, H 2 O and some trace fuel oil vapor is recovered from the reducing portion of the rotary kiln and re-introduced into the end of the kiln to flow countercurrent to the advancing reduced ore. The traces of fuel oil vapor in the recycle flue gas provide the necessary reductant to reduce any iron (III
