It would, but smelting is not a process that likes being started and stopped. Once furnaces and other bits and pieces are up to temperature they want to stay there. Thermal expansion is a thing, but also letting them all cool down is throwing energy away. And iron workers don't like sitting around "on call" waiting for energy prices to swing enough to justify going to work.

Same too with customers. The people buying bulk metal need is when they need it. They don't want to wait around, literally, for the winds to change.
