The AISI direct steelmaking project evaluated a continuous refining process for the conversion of hot metal as from a bath smelter to steel. 10 The project studied a single zone and two zone reactors. In the two-zone reactor, hot metal is decarborized to approximately one percent carbon. Final decarborization occurs in the second reactor.

A slab casting of uniform dimension, shown in figure 21, demonstrates directional solidification. The metal is poured through the riser, and as it flows over the mold surface, it gives up some of its heat to the mold. Such a condition will mean that when the mold is filled, the metal at the right end will not be as hot as the metal near the riser.
