Induction Furnace is the top tier of IndustrialCraft 2's electric smelting line — an upgraded Electric Furnace that processes two item stacks simultaneously and saves 50% of the energy those stacks would cost smelted separately. The Induction Furnace draws 16 EU/t and accepts low and medium voltage up to 128 EU/t; above that ceiling the Induction Furnace explodes, and Transformer Upgrades offer no fix. The Induction Furnace also buffers 10,000 EU internally, riding out short power dips. The signature mechanic is heat: every smelting operation pushes the heat gauge toward 100%, and at full heat one operation costs 208 EU instead of 6,000 EU and finishes in 0.65 seconds instead of 18.75.
Heat management decides whether the Induction Furnace pays off. Warming from 0% to 100% takes 10,000 ticks — 8 minutes 20 seconds — and about 10,000 EU, while an idle Induction Furnace cools four times faster, dropping back to zero in 2 minutes 5 seconds. A constant redstone signal holds the heat at 1 EU per tick while idle, so veteran players wire the Induction Furnace into an always-powered smelting room and load both input slots before big batches. Craft the Induction Furnace from an Electric Furnace, an Advanced Machine and copper. Two upgrade slots accept ejection and pulling upgrades for automated lines, and a Wrench dismantles the Induction Furnace without risk.
