Point Feed Prebake cells and Bar Broken Prebake cells - это то подвиды метода Centre-Worked Prebake (CWPB) http://www.proz.com/kudoz/1701734


В этой ссылке этот метод описан, но как перевести, не знаю:

Prebake technology is also subdivided into several categories depending on the type of alumina
feeding mechanism. The most modern of these technologies is the Point Feed Prebake cells
(PFPB) where the crust is broken at multiple points along the centerline of the cell by mechanical
punches. Alumina is then dropped into the cell through the newly established opening. In some
older prebake cells, feeding is accomplished by a metal bar extending along the centerline of the
cell that periodically breaks the surface cover and feeds the cells. These cells are referred to as
bar broken Center Work Prebake cells (CWPB). In yet another cell design, the cell is fed from
the sides rather than the center and these cells are referred to as Side Work Prebake cells
(SWPB).
