Purpose. Substantiation of solutions aimed at reducing heat losses, mainly, by refractory lining during forced downtime and steelmaking bath in conditions traditionally low specific power transformer. Methodology. Mathematical modeling mass transfer processes numerical experiment. Findings. A mathematical model energy-technological arc furnace workspace has been developed to analyze minimize en...

SiC nanowires have been synthesized at 1,600 degrees C by using a simple and low-cost method in a high-frequency induction furnace. The commercial SiO powder and the arc-discharge plasma pretreated carbon black were mixed and used as the source materials. The heating-up and reaction time is less than half an hour. It was found that most of the nanowires have core-shell SiC/SiO(2) nanostructures...

smelting of hammerable iron and its treatment in antiquity and Medieval produced also by-product: slag. Because of small yields of iron the process produced only small amounts of slag that did not attract attention of smelters concerning its possible use. the use of slag pieces was only accidental. a lot of slag pieces and blocks from slag pit shaft furnaces were used as a material for mound bu...
