Ingot Train

Normally, an ingot train would run inside a mill between the teeming facility in the open hearth building, the mill's yard tracks to let the steel cool, and the stripper in a rolling mill. [PracticalMachinist] Now ingots are obsolete because of continuous casting. The special heavy duty flatcars that carried the ingot molds were called ingot buggies.

Michael Riha posted two photos with the comment: "Been awhile since I posted, so William O'Neal Stringer's post about the ingot train inspires these shots from one of my first trips to Calumet Ave on the lakefront...long before CN or even the casino."
Steven Suhs I recall handling one of these had 2 300’s. Was interesting to hold the speed at 15 mph when loaded when the 300’s did not have speedometers.
Chuck Olen Olejniczak I worked at US Steel South Works where we filled those molds with molten steel from the #4 Electric Furnace shop. They were sent to Gary Works to be stripped and rolled at the plate mill as our plate mill was closed in the early 80's.

What we are looking at is really the molds holding the ingots. A machine called the stripper will lift a mold by the round lugs near the top and then a hydraulic plunger will shove the ingot out.



[There are no lugs at the top. Is the base put over a hole and the ingot is pushed through the hole?]

In front of the caboose is a steel ingot load.

Here we can see why they were called buggies. It looks like just two molds per car 2-axle car.

[Another model. Since ingot trains normally stayed in a mill, there won't be too many railfan photos of them.]
[I can't tell how many axles this buggy had.]
[The ratio of one mold per two axles is rather common.]
The buggies were also used to carry trays holding scrap metal that were used to charge open hearth furnaces.

[Note the cut of ingot cars in the middle of the photo. We are looking at the south side of U.S. Steel South Works.]
Ingot stripper in Homestead, PA  I could not find a date for this photo. The steel mill is not only gone, the brown land has been redeveloped.

John W. Coke shared his post of two photos with the comment: "Lehigh Heavy Forge Corporation, Hot ingot transport car. Photo by Barbara Ryan, Horseshoe Curve, October 2004."
Richard Middlekauff It is used to transport hot steel billets. We used to see them regularly thru Harrisburg from Steelton, hauling billets to Lehigh Heavy Forge. We had a Conrail engineer explain that there was a 16 hour window from when the billet hit the floor of the car to delivery at the forge. They would pull four or five of the cars up from Steelton to the Harrisburg yard. They hustled to connect them to the front of an eastbound stack train and take off.
Patrick Carroll I would assume that it was around 1600*-1800* Fahrenheit

Noe Gutierrez LHFX 37000 is a former Bethlehem (BFIX) car. It's a "hot ingot car"     Four 3-axle Buckeye trucks enables the car to have a rated capacity of 744,500 pounds, or just over 372 tons.


Mikl Lussier commented on John's share
From their site :
<<Lehigh Heavy Forge has earned the elite status of Forgemaster.
Starting with ingots up to 285 tons, our 10,000 ton open die hydraulic press produces the largest forgings in the western hemisphere with ship weights exceeding 166 tons. In addition we also operate a 3,000 ton open die hydraulic press for work roll forgings, billets and smaller forgings of various configurations with ship weights starting at 10 tons.>>
