Vacuum Degassing of Steel - Vacaero

During the steelmaking process, while the molten steel is still in the ladle and before it is poured, the steel must be degassed in order to: (1) reduce/eliminate dissolved gases, especially hydrogen and nitrogen; (2) reduce dissolved carbon (to improve ductility); and (3) to promote preferential oxidation of dissolved carbon (over chromium) when refining stainless steel grades.

Dolomite – Its Processing and Application in Iron .

The most common process for the production of sintered dolomite is a single stage firing process in a shaft kiln or a rotary kiln. The raw dolomite is charged into the kiln and, while progressing through the kiln, it gets decomposed in two steps. In the first step CO2 is released from the MgCO3 component of the dolomite starting at around 550 deg C and in the second step CaCO3 component is ...

Chapter 18. Feed Milling Processes

Mechanically, the process of pelleting involves forcing soft feed through holes in a metal ring-type die. These holes may be round or square, tapered or non-tapered. Single or double rolls mounted inside the die ring on a cam or eccentric, turn on a rotating shaft as friction develops (due to the presence of feed between roll and die). Feed is forced through the die holes in increments so that ...
