Description

Used to smelt ore into ingots and alloys using an oxygen/volatile gas mix. Ice (Oxite) and Ice (Volatiles) can be manually input directly in the furnace in order to create crude gas mixtures, or to be directly extracted as an easy trick for melting the ice.

If the contents of the furnace are ejected without reaching the required temperature and pressure for smelting, they'll come out as Reagent Mix which can be processed in a Centrifuge to recover the raw ores. Reagent Mix can also be re-smelted if the ingredients and ratios are a valid alloy recipe. This allows an intermission when the resources for reaching the required temperature / pressure are not on hand / need to be gathered first. Effectively, this means that the used metals can be 'reserved' for the intended alloy.

Recipes

While smelting steel is easily achieved with ice, other recipes usually require a working piping setup (a valve and passive vent at bare minimum to vent the internal gasses). This can be done by separating gases into tanks using atmospheric units and piping individual gases through a mixer and a Pressure Regulator or a Pipe Volume Pump connected to the furnace input. Output should also be extracted and vented/recycled through a backpressure regulator to keep furnace pressure in check. The optimal gas mix that burns completely is 1 part (33.3%) oxygen to 2 parts (66.6%) volatiles, other mixes would also work but leave you with leftover oxygen or volatiles depending on the percentages used. It could also result in lower temperature if that is desired, but you could also use a volume pump with a lower fuel input setting.


Make sure to put the fuel in first, then press the activate button. Afterwards put in the ingredients and press the handle after you see the "will produce" while hovering over the furnace. Also, You MUST put in exact amounts matching the recipe amounts. For instance, you must put in 12 iron and 4 coal to make 16 steel. You cannot put in 12 iron and 7 coal. The furnace will not manufacture anything if the ingredient ratios are not correct and you will have to eject it all or add resources to balance the recipe.

Tips

  • Placing 15 ice(volatiles) and 15 ice(oxite) will bring pressure to around 22000kpa and temp 2000k. For Invar, you will have to wait for the temperature to drop before you can process. You can use this time while the pressure is still over 20000kpa to make constantan.
  • All other alloys can be achieved with a ratio of 2 volatiles to 1 oxite
  • If atmosphere inside and/or around furnace is too cold to melt ice one can press 'activate' button to manually melt one ice per ignition attempt. You will need to press the ignition button for each piece of ice from the first stack that you put in. Until all solid matter was melted the import slot will remain blocked.
  • Reagent Mix can be re-melted to continue balancing the recipe should you need to gather more resources or find yourself unable to balance the temperature/pressure manually.
