KEY WORDS: briquetting; cement replacement; granulated blast furnace slag; fly ash; tumble strength; isothermal reduction. 1. Introduction As the implementation of traditional sintering plants is receding, the cold-agglomerated briquetting process is increasingly favored in recycling secondary raw materials to the blast furnace (BF).

Slag, being a material of lower density, flows out over the surface of molten iron in blast furnace and is removed at regular intervals from the furnace. The GBSF temperature at the blast furnace output reaches about 1400 ÷ 1450 °C and it is cooled slowly by means of air or quickly by waterjet. The latter process is called granulation and ...
