Longitudinal crucible gaps filled with conductive packing boost resistive heating, raising graphite output while cutting power use.
Using different fuel gases across heating and equalization zones cuts CO2 while limiting scale formation and hydrogen uptake in steel.
Different fuel gases in furnace ceiling and side burners cut steel scale and hydrogen uptake while supporting lower CO2 heat treatment.
A thermally insulated core with dual temperature sensing tracks heat flow to estimate refractory thickness continuously without downtime.
Radar, laser profiling, and AI separate refractory thickness from slag buildup in furnaces and ladles to improve maintenance timing.
