Viewed from the backyard gardens of Brandywine Mansion, post 1890, the mill building on the far left houses the new open hearth furnaces. |

This view, post-1900, shows the original Open Hearth building in the foreground. Open Hearth #1 was originally built in 1890 with two 30-ton open hearths. It was quickly expanded. The two 30-ton furnaces were upgraded to 35 tons, and four new 35-ton furnaces were installed to bring the total to six 35-ton open hearths, one furnace for each stack. Notice also the Pennsylvania Railroad bridge, built out of steel, is in the background. |

This view shows the heart of the Lukens Steel Company, post-1918. To the left, in front of the large, single stack, is where the 206" Rolling Mill and Spun Heads Departments are located. The low building to the right is the first Open Hearth #2, where ten 50-ton furnaces are located. Open Hearth building #3, to the right of that, houses the eight 90-ton furnaces. The two stacks in the extreme right are two 35-ton furnaces from Open Hearth #1. |

Electric Arc Furnace |

A new kid of steel-making building with no stacks houses the Electric Arc Furnaces. Planned in the early '50s, these furnaces came on-line in the late '50s with "A" Furnace a 50-ton furnace. While of a lower tonnage than the open hearths, these furnaces reduced drastically the time between taps from 8 hours per heat to 1-1/2 hours per heat. They used less fuel to keep hot and that fuel, electricity, they did use was more environmentally friendly than the open hearths, which burned coal. |
