The SL/RN Process is the most widely used coal based reduction Technology the world. The iron ore, coal and flux charged into the rotary kiln are rapidly heated up by the combustion of coal volatiles released in the charge using the specially designed RN inderbed air injection system. The reduction of iron ore in the solid.

SL/RN Process | Industrial Efficiency Technology & Measures

The so-called Stelco-Lurgi/Republic Steel-National Lead (SL/RN) process is a widely used coal-based DRI-making process which uses a rotary kiln. The process uses lump ore, pellets, beach sand or ilmenite ore and solid carbon to produce hot or cold DRI. The process operates at high temperature and atmospheric.
