FURNACE STRUCTURE & SHUNTS: Rolled steel sections are welded to form hydraulic tilt structure. Shunts are bolted to steel columns centralize the coil, which in turn supports the refractory. Shunts are designed to avoid heating of the other steel parts, reduce stray losses and improve efficiency.

FURNACE COIL: Heavy extruded Rectangular Copper section Coil is designed on computer for extra efficiency, strength & rigidity. Studs brazed to coil are bolted to vertical supports to guard against vibrations & refractory expansion. High voltage insulation on coil avoids inter-turn sparking. Spacers are used to maintain the inter-turn gap.

COOLING COILS: The top & bottom cooling coils made up of stainless steel evenly cool the refractory to minimizing its cracking, spalling & overheating.

MAGNETIC SHIELD: Thick faraday shield is used at the bottom to avoid the bottom overheating. Cooled copper ring at the top reduces stray losses in the top structure.  

FREE BOARD: 10 - 20% free board above the coil assists furnace charging without effecting the stirring pattern.
