Just learned the old Bessemer converter at the Pittsburgh plant could process a 25 ton heat in under 20 minutes.
I was reading a history book about steel towns from the library. It said the Bessemer process was so fast, the whole pour was done before the furnace lining got too cold. I always thought those big heats took hours, not minutes. Has anyone else come across old facts about our trade that blew their mind?

That speed is wild. Makes you wonder how many heats they could run back to back before a full reline.

Probably not many, honestly. That kind of wear has to be crazy.
