Furnace lining is kaowool coated with a coating called "zircoat W" I purchased mine from cast metal services australia.
Hmmmm, I would like to know where I could get cast iron ingots with a known composition and for a reasonable price!
I use only scrap cast iron because I can get it for nothing, having said that not all scrap is the best to use. I have been melting cast iron for a long time and know what to avoid but to explain to a beginner what to use can be difficult. If there has been any machining done to it, holes drilled etc. it can be remelted. Modern cast irons can change when remelted so it is important to have some ferrosilicon to add so the iron can be machined. Thank you for watching the videos.
