Creating Steel

The advantage of steel over iron is greatly improved strength. The openhearth furnace is one way to create steel from pig iron. The pig iron, limestone and iron ore go into an openhearth furnace. It is heated to about 1,600 degrees F (871 degrees C). The limestone and ore form a slag that floats on the surface.

Disc Pelletizers (Pan Pelletizers)

Disc pelletizers utilize a nonpressure (tumble growth) approach to agglomeration and work by tumbling material on a rotating disc, with a binding agent and feedstock being continuously added. The binding agent causes the fines (or seed pellets, when utilizing a preconditioning step) to become tacky and pick up additional fines as the material tumbles against itself.
