The only things which effect steel quality now are the crucible's quality, the quality of the wrought you are using, and the quality of the charcoal in the slots. The fuel you use is completely irrelevant.
You ought to be filling a couple palisade signs near the crucibles, then taking out 4 blocks, turning them into branches, and filling with those. Doing so means refueling them is a couple minute process at best, and makes it considerably easier to fit in. 12 hours is a pretty long time, especially when you only have to remember to spend 2-3 minutes twice a day.
