“…vibropressing, roller pressing and the stiff extrusion. The stiff-extrusion technique which was mastered by J. C. Steel & Sons (USA), had its 1st industrial application in the year 1993 [1]. In this cold briquetting technology various steel plant by-products can be easily agglomerated using very few amount of binder material and also cost effective than other agglomerating processes, due to their less processing steps.In this advanced technology homogenizing mixture of raw materials with the moisture content of 12-16% passes through the vacuum chamber and then pushed through the die holes by pressure 3-3.5 Mpa [2].…”

Abstract. Different metallurgical wastes are generated during pyro processing of iron ore, which is used for making sponge iron or hot metal and for producing steel. Apart from these wastes, coke fines are generated during the coke making, and iron ore fines are generated during mining of iron ore. Although iron ore fines are used for making pellet after beneficiation still, it generates a huge quantity of iron ore waste during beneficiation with comparatively lower iron content. In the present study, briquettes are made by a stiff extrusion process from metallurgical waste like iron ore fines and coke fines with the addition of Portland cement as a binder and clay as a rheology modifier. Physical properties of the briquettes are evaluated, and reducibility of the briquettes is studied in comparison to lumpy iron ore. Phase analysis and microstructural analysis of the briquettes and lumpy iron ore are carried out after firing at different temperatures in the simulated blast furnace condition. Physical and mineralogical properties are correlated with the reducibility of the briquettes and lumpy iron ore. Briquettes made by a stiff extrusion process show a better mechanical strength fired at a different temperature to take the load of burden and better reducibility than lumpy iron ore. The briquettes after self-curing are charged to a 23 mt3 blast furnace which shows encouraging results.

“…The main distinctive features of the stiff extrusion technology were studied and described in details earlier. [3][4][5][6][7] In particular it has been established that the green BREX do exhibit appropriate mechanical strength and require less amount of the binder to achieve the strength levels required by the metallurgical furnaces. The capacity of the industrial stiff extruders ranges from 15 to 115 tons per hour.…”

Stiff vacuum extrusion has been applied for the agglomeration of the iron ore concentrate and fine coal. The products of agglomeration-extrusion briquettes (BREX) were subjected to the high temperature reduction. Under the conditions similar to the ITmk3 process in general. It has been demonstrated that the iron ore and coal BREX could be considered as the alternative to the iron and coal pellets for the high temperature reduction in furnaces like Rotary Hearth Furnace (RHF).
