The partition wall 16 is located between the outer walls 14 and is always located inside the furnace body, and both sides of the partition wall 16 need to bear high temperature and high pressure, so that when no I-steel support is provided at the interval of the conventional Acheson furnace, the partition wall 16 should have a width larger than the thickness of the original wall.
