Codex Processing Induction Furnace

Induction Furnace

The Induction Furnace smelts with energy instead of fuel: every furnace recipe of every mod in half the furnace time, and alloys from two ingredients. It is one of the four machines you can build from the start, and it makes the steel that most later machines need.

Property	Value
Tier	1
Energy buffer	20,000 E
Max. input	4000 E/t
Input slots	2
Output slots	1
Upgrade slots	3
Recipe type	Induction Smelting

The Induction Furnace window: 1 input slots, 2 progress, 3 output slots, 4 upgrade slots, 5 energy and tank bars, 6 value, status and redstone lines, 7 buttons (redstone mode, telemetry, codex).

What it does

Put the items into the two input slots and give the furnace energy. One run takes the ingredients, uses energy every tick and puts the product into the output slot. For an alloy, the two ingredients may lie in either slot.

The furnace knows two kinds of recipes:

• Smelting: every recipe of the normal furnace, from Minecraft and from every other mod, becomes a furnace recipe here. It takes half the time of the furnace (at least 1 second) and 30 E per tick. Smelting recipes whose ingredient or result carries extra data (a name, an enchantment) are left out. The furnace gives no experience.
• Alloys: two ingredients become one alloy.

Alloys

These recipes come with QNet. Alloys of metals that only other mods add (tin, zinc, nickel, silver) exist only while some mod adds an ingot of the alloy and of its metals; dust works as well as ingots where the recipe allows it.

In	Out	E/t	Ticks
3 × any Copper Ingot, any Zinc Ingot	4 × any Brass Ingot	60	200
3 × any Copper Ingot, any Tin Ingot	4 × any Bronze Ingot	60	200
any Copper Ingot, 4 × any Redstone Dust	Conductive Alloy Ingot	60	200
any Copper Ingot, any Nickel Ingot	2 × any Constantan Ingot	60	200
any Gold Ingot, any Silver Ingot	2 × any Electrum Ingot	60	200
2 × any Iron Ingot, any Nickel Ingot	3 × any Invar Ingot	60	200
any Iron Ingot, 2 × any Coal Dust	any Steel Ingot	60	200

Tip

Steel first One iron ingot (or iron dust) and two coal dust give one steel ingot. Coal dust comes from the Crusher. Steel plates, rods and gears from the Metal Former are the base of almost every QNet machine.

Energy and upgrades

The furnace takes energy on every side, from a Pipster cable, a generator next to it or any FE or Team Reborn Energy source. When the buffer holds less than one tick of the current run, the run waits and keeps its progress.

The three upgrade slots at the right edge take one kind each:

Upgrade	Up to	Effect per upgrade
Speed Upgrade	2	half the time, 2.8 times the power
Efficiency Upgrade	3	0.85 times the power
Parallel Upgrade	2	2, then 4 copies per run, 1.25 times the power per doubling on top

Upgrades count from the next run. The buffer and the maximum input grow by the same factor as the power. A parallel run only starts as many copies as the inputs hold and the output has room for.

Automation

• Pipes, hoppers and other mods can put items into both input slots from every side, but only items that some recipe of the furnace uses.
• Upgrades can be inserted the same way; each slot takes only its own upgrade.
• Items can only be taken out of the output slot.
• When the output is full, the finished run waits until there is room.

Redstone

The R button in the top right corner switches the redstone mode: always runs, runs with a signal, or runs without a signal.

What the status line says

Status	Meaning
Idle – waiting for inputs	No recipe fits the inputs (or they are empty).
Running	A run is in progress.
Waiting for energy	The buffer is too low; the progress is kept.
Output full – take the products out	The product of the finished run does not fit.
Paused by redstone	The redstone mode stops the machine. A Grid Monitor that pauses machines shows the same text.

Building it

The Induction Furnace needs no components: iron and copper ingots, redstone and a normal furnace in the middle.

Iron Ingot	Copper Ingot	Iron Ingot
Iron Ingot	Furnace	Iron Ingot	→ Induction Furnace
Iron Ingot	Redstone Dust	Iron Ingot

When you break it, it keeps its energy and its redstone mode; items, upgrades and the ingredients of a running job drop.

In the world

While it runs, the item sits in the mouth of the crucible, turns slowly and shrinks as it melts, while the fan on top spins. Small flames flicker above the crucible, a soft hum plays now and then, and the furnace gives off a little light.

Tip

Dust instead of ore Ores smelted here give one ingot. Crush them first: two dusts per ore, and each dust smelts into an ingot in half the furnace time.

Note

Large amounts For many items at once, the Tunnel Furnace smelts tray after tray with process heat.
