From platinum melting to rare-earth reduction, tomorrow’s high-purity metals demand temperatures above 2,000 °C and atmospheres that dissolve steel. Success hinges on thermally stable, chemically quiet and dimensionally precise tooling that survives thousands of rapid heat-cool cycles without contaminating the melt.
Carbon stands in for ceramics and metals where they fail. Graphite electrodes arc 200 kA through scrap in EAF furnaces, converting megawatt-hours into liquid steel in minutes; isostatic graphite crucibles and setter plates carry powders through 1,600 °C sintering cycles without creep or spall; lightweight graphite insulation barrels lock heat inside furnaces, cutting energy loss and holding tight dimensional tolerances. Inert to most slags and salts, these graphite components let producers raise temperature, shorten cycle time and reach ultra-low impurity levels.
From mega-ampere graphite electrodes to machined crucibles and vacuum-tight insulation barrels, Harog Technology supplies the carbon backbone that turns ores and powders into high-grade metals and chemicals-helping metallurgists and chemists run hotter, cleaner and more efficiently.
