Complete with ore crushing, limestone generation, iron ore fab system from iron nuggets, cobblestone and limestone, charcoal to coal converter, coking oven, blasting mixture converter, wasteless feed system, working roatary kiln, power generation, control room, flarestack, creosote storage, casting station and two train stations for lava supply/creosote export, train station for liquid steel and slag transport and raw supply feed. Designed in creative but built in survival. The material list is ridiculous. The schematic also includes the two trains. The build is based on real steel production plants. Hope you like it!

Important:
Test the schematic in a test world before building it. It might crash your game. I had no issues but other hardware might respond diffently. Also the schematic sometimes screws up the girders, walkways/railings, tanks, vaults, list filters and lamps. Vaults and Tanks have to be rebuilt to fix it, list filters must be placed correctly or even be replaced. The list filters on the tunnels must be relocated correctly. If you have trouble with this, hit me up. In general some adjustments after building might be necessary. Schematic needs to be placed a few blocks under ground because of the basements and underground shafts/belts.

If you want to build this in survival, you'll need an iron and maybe a deepslate farm, as well as access to some steel. The material list is about 30 pages long.

Have fun with your steel plant. Will post some more schematics in the future :)
