摘要： A beam structure is described for supporting rails that carry wheeled cover carriages employed to close the openings of chambers in an industrial furnace of the soaking pit type. Each beam is disposed on the median wall between adjacent chambers and is arranged to mount a pair of rails, each of which is associated with one of the two adjacent chamber openings. The beam is structured and arranged to rapidly dissipate heat acquired during periods of furnace operation and especially due to exposure to the interior of the furnace when the associated cover is removed to thereby protect against undue thermal stressing. Ancillary insulating means may be appended to the structure in the most severely affected regions thereof.

摘要： Improved bits for ingot tongs, an improved tong-and-bit combination, and an improved method of handling ingots. The bits are formed of a durable metal, such as a nickel alloy or a cobalt alloy, and are rotatably fastened in the tong arms. Protrusions from the outside faces of the tong arms are avoided to prevent damage to parts struck by the tongs. The distance by which the points on the bits protrude from the inside faces of the tong arms can be adjusted for different sizes of ingots. The method includes a step of rotating the bits through a small arc each time an ingot is set down, whereby a fresh area is presented upwardly after each use and wear on the bit point is distributed around the circumference.
