The paper embodies the influence of thermal treatment on the morphology, composition and leaching behaviour of titania slag. When Ti-slag was subjected to heat treatment, it developed pores and oxidized at high temperature. This slag consists mainly of a M3O5 phase with an orthorhombic structure. The decrepitation was studied by oxidizing the titania slag sample produced in a pot/muffle furnace...
This paper examines two mold powder related process problems experienced at BHP's Whyalla operations. Bands of deep transverse depressions extending about the perimeter of the strand in the first meter of cast product were identified as a potential cause of breakouts. These were associated with level drops in the mold during startup that allow sintered material to accumulate against the mold wa...
Basic oxygen steelmaking (BOS) slag, a product of hot metal element (e.g., Si, Mn, Fe, P) oxidation and flux (e.g. lime, dolomite) dissolution, plays critical role in the production high-quality crude steel, although its behavior inside BOS vessel (formation reaction with droplets gas) is still not clear recycling has always been challenging. Herein, examples BOS-slag-related research conducted...
This study analyzes six slags excavated from the iron making site in Gogi-ri, Namwon, Korea to understand characteristics of ruins, and confirm process performed at time. The chemical components by-products Gogi-ri were analyzed, findings indicate total Fe contents between 23.24% 37.56%, which are lower than typical content found ancient processes. deoxidation agent ranged 43.88% 58.13%, higher...
The Yodhawewa archaeometallurgical site was the latest discovery in Sri Lanka 2018. This study aimed to trace archaeological and geochemical relationship by analyzing soil slags of dating back c. first eighth centuries AD. analysis mainly based on X-ray fluorescence (XRF) method. chemistry resulted some clues special metal processing zones excavation-1 area. cultural layers that area (profiles ...
