The electric smelter is used to extracts steel from steel slag chunks and metal weapons and armor. Colonists assigned to crafting will make use of it.

Acquisition

It is built with Steel 170 Steel, Component 2 Component in 3,500 ticks (58.33 secs) after the research Electricity has been completed.

Summary

Electric smelters are placed on the ground and require 700 W of power. Powered electric smelters can convert steel slag chunks, metal weapons, and metallic armor pieces into usable metal. Smelting Speed is not affected by skills, but can be increased by manipulation and Global Work Speed.

While powered, smelters output light in a 6 tile radius; the nearest 3.442 tiles are above 50% light level and considered "lit", negating the work speed penalty from darkness. Smelters also produce heat while in process of smelting things (amount comparable to output of one heater). No heat is produced when idle, even if powered on.

Work

Steel slag chunks are melted into Steel 15 steel after 400 ticks (6.67 secs) of work.

Weapons and armor can be smelted to return 25% of their crafting cost, minus any components, advanced components, or chemfuel, after 1,600 ticks (26.67 secs) of work. Smelting will convert the same items to the same materials, regardless of quality, damage, biocoding, or tainting.

The smelter also has the option to destroy weapons and apparel for no gain, which works even for nonmetallic items.

Analysis

Smelters are undoubtedly useful for steel slag chunks, tainted clothes, and biocoded weapons, which are all outright unsellable. Meanwhile, damage will quickly reduce the value of an item, so you could receive more silver by smelting. When making smelting bill(s), take these factors into account.

Destroying items is rarely worth it. The destroy bill can help get rid of unsmeltable items like cloth apparel and stone clubs. However, most of them can be sold for silver, which brings a little profit (as opposed to none at all). It has some use in wealth management, though you can also create a caravan and drop items on the world map, destroying them all the same.

As smelting is unaffected by skill, the fastest smelters are those with bionic arms (or better), or have work speed modifying traits like Industrious.

Sell vs Smelt

This graph shows dependence item sell price multiplier($) from item hit points.

For items that you can both sell and smelt, the table below describes the sale value (excluding sell/buy penalties and pawn trade skill) of the items at each quality, alongside the value of the raw resources that can be attained by smelting. Items made of different kinds of stuff do not have data. In parenthesis are the hit point percentages at which the item's value is equal to that of the raw resources. Above this percentage it is better to sell the item, where as below the percentage it is better to sell the raw resources. Note that this only considers selling each, so the cost to buy the same raw resources is not included.

In general, very damaged items (under 60% health remaining, the value of an item drops rapidly after 60 percent) are better to smelt, as the sale price is reduced while the amount of resources recovered are unaffected. Note that items with 90% or more health remaining retain full value.
