Abstract:

In a previous publication at FLOGEN SIPS 2016, ORIEN Technology was introduced as a new technology that is compact, energy intensive and self-sufficient. It is also environmentally friendly with numerous advantages compared to the classical iron and steel production technologies. In a subsequent paper at FLOGEN SIPS 2017, the basic physicochemical principles of this process were described. This included its special characteristics of direct liquid-state reduction of unique iron-ore cold-pressed briquettes which simultaneously achieve the reduction of iron ore out of the briquettes and convert it into steel. This process is performed in a single electric furnace unit and produces a unique iron melt of a special type in which the carbon exists in a non-equilibrium colloidal form that can be controlled to vary widely from 0.04% to 30%. This paper describes various unique characteristics and advantages of this process in terms of energy saving, environmental protection, economy and steel quality.
