During the period per-iod the Ironton ovens are on standby, high quality coke for the plant's No. 2 blast furnace fur-nace will continue to move by rail from nearby Geneva. To return cold standby ovens to production, the batteries are slowly heated and the protective protec-tive coating scraped from the top. As the brickwork expands, the tie rods or framework are slowly loosened which is much the same procedure as is followed for new ovens.
