Abstract:
Industrial stiff vacuum extrusion briquettes (BREX) producing line can efficiently provide for the small-scale blast furnace (BF) operation with 100% briquetted charge. Physical and metallurgical properties of the BREX are being investigated. A new effect of the non-linear strengthening of the BREX bonded with the combined Portland cement and Bentonite binder is described. The application of this combined binder results in the local maximum of the cold compressive strength of the BREX on third day of strengthening. The hot strength mechanism of the BREX is being explained. The results of the industrial operation of the small-scale BF with 100 % BREX in burden are analyzed. The consumption of coke in the BF at 100% of BREX does not exceed 500 kg/t compared to 680 kg/t for the smelting without BREX.<br />
KEY WORDS: extrusion briquette (BREX); stiff vacuum extrusion; small-scale blast furnace; coke rate; hot strength.
