The strand casting machine isnt in yet, so I probably forgot to change the category there, will fix that for the next version.
The smelting processes are close to real world counterparts so dont blame me for chemistry stuff

I fixed the acid mix up for the ore in the next petrochem version. I might add acid requirements to other infinite variant later on, depends on how well it is received
Does it just not match the consumption elsewhere in bobs?
