Coal furnaces are not used in mass steel production for 150+ years.
When they were used long time ago, they were not operated continuously.
May be, you mean pig iron production?
Here, indeed, coal (coke, in fact) furnaces are operated continuously for very long periods - like many months. Still, it's much shorter than lifetime, which tends to be several tens of years.
