Abstract
Electric arc furnace slag (EAF slag) is an industrial solid waste generated at steelmaking process. The increase in steel consumption in Egypt is thus the cause of the generation of EAF slag, and, consequently, the growth in EAF slag amount had impact on thinking to find and develop various methods of slag utilization. The Ezz flat steel company in Suez, was chosen as the case study for the current work as one of the biggest company for steel production. The glass samples batches were designed and produced firstly from pure powder additives as a reference glass (soda-lime silicate glass), and secondly by addition EAF slag up to 50 wt.%. The starting materials, the produced glasses and glass-ceramics were characterized using different techniques in terms of XRF, XRD, FTIR and SEM equipped with EDS advanced techniques. The mechanical properties of glass and glass ceramic materials in terms of hardness were also evaluated. The suggested production process (batch design, melting parameters med annealing process) succeed to produce glass materials containing different weights of EAF slag up to 30 wt.%. Furthermore, the reflection index and the ultra violet absorption were measured for the produced glass. The transformation temperature (750 oC) from glass to glass-ceramic was determined based on many laboratory experiments and using differential thermal analysis (DTA) test for the produced glass powder. The designed heat treatment regime succeeded to convert the produced glass materials to glass-ceramics. Mechanical properties in terms of hardness of the produced 2 glass and glass-ceramic materials are related to the chemical composition of the starting batch powder and heat treatment process. It reached a value of 640 and 840 HV for glass-ceramics containing 0 and 30 Wt.% EAF slag, respectively. Finally, the current work succeeded to utilize EAF slag industrial solid waste to fabricate glass and/ or glass-ceramics contained up to 30 Wt.% slag and it gives the opportunity to open new investment in Egypt.
