The Cast House is the area within the Blast Furnace where liquid slag and hot metal are tapped into several different types of cars and ladles. Both the cars and ladles transport blast furnace output to pig casting, open hearth, and Bessemer steel making processes; reserved in hot metal mixers, or disposed of in cooling pits.
Exemplary Pollock Contributions
Hot Metal Ladle
About: Refractory-lined chamber holding about 75 tons of liquid metal. Requires a suspension.
Advantages: Ease of transport from the Cast House
Cinder Car
About: Unlined, tulip shaped car used to tap and transport cinder to the slag dump.
Advantages: Fast dumping times via manual or mechanical means.
Kling Car
About: Refractory-lined, spherical in shape with an opening at the top where the iron enters.
Advantages: less radiating surface and longer cool times
Mixing Car
About: Refractory-lined, cigar shaped chamber designed to transport increasingly large quantities of molten metal.
Advantages: iron can be poured directly into the car while mixing and transportation operations are simultaneous.
Slag and its Disposal
Slag and its Disposal
Slag is a byproduct of steel making operations which is incidental to the concrete and insulation industries.
Once the Blast Furnace is tapped, slag flows directly into cinder ladles and is carried to cooling pits for further processing.
