Publisher's Synopsis
Excerpt from Present Development of Heavy Ordnance in the United States
The ladle is then transferred by rail to the fluid com pression plant* where the steel is compressed or run into the moulds for which the metal has been intended. The sizes of the ladles are governed by the capacity of the furnaces and the class of work for which the steel is to be used. Of heavy iron construction they are lined with a refractory mixture and pierced in two places in the bottom for the insertion of fire-brick nozzles, through which the metal runs into the moulds. Into these nozzles clay-plum bago stoppers are fitted and attached to heavy rods which extend upward and out over the side of the ladle to the levers or other attachments provided for lifting and con trolling them. The device shown in the view* is a simple and effective one. The moulds are of steel, iron, brick, or sand, and are of dimensions and shapes suited to the purpose for which the ingot or casting is to be used. Bethlehem has four open-hearth melting furnaces, of the respective capacities of fifteen, thirteen, and two forty tons.
