Achieving carbon neutrality in the hard-to-abate iron and steel industry requires feasible mitigation at plant level. Presently, decarbonization pathways are mainly assessed country or sector level, whereas specifics regional differences socioeconomic conditions have been underexplored. Here, we take China, world’s largest producer, as an example assess level using a provincial AIM/Enduse model...

Carbon nanotubes (CNT) are produced from a rare variety of natural vein graphite (VG) distinctive to Sri Lanka using electric arc discharge. Electric arc-discharge produces both single walled and multi walled nanotubes. The products are characterized using high resolution electron microscopy and Raman spectroscopy for verification and validation. Keywords—CNT, vein graphite, arc discharge, SWCNT

Abstract In the present study, a modified duplex melting process was set up so as to be able produce an EN-GJL-150 gray cast iron from local manganese-rich pig iron. A descriptive statistics showed average Mn and Si content in raw material such that: % = 2.457±0.133 0.682±0.088. The demanganization run monitored cascade of two industrial-scale furnaces: rotary kiln electric arc furnace. perform...

Annealing furnaces are used to heat steel in order to change its chemical structure. In this paper we model an electric radiant furnace. One of the major defects in steel strips processed in such furnaces is a wave-like pattern near the edges of the strip, apparently due to extra heating near the edges. The aim of the paper is to model this effect and provide a way to calculate the elevated tem...
