High output AOD industrial refining furnace
Description of AOD industrial refining furnace
AOD is the refining equipment of argon oxygen decarburization. It’s named after the acronym of its English
name. Its configuration is similar to converter which is set on a support ring tilting front and back and is fixed
with dowel. On the side bottom of the furnace, spray lances are set to blow gases towards the horizontal
direction of the molten pool. The number of spray lance is different according to the tonnage of the furnace,
generally 2-3. The extension cord of spray lance coincides with the vertical spindle of furnace. Spray lance is made up of
inner pipe (copper) and outer pipe (stainless steel). Inner pipe is used to import the main blowing gases
(made up of Ar-O2 or Ar-N2). Annular gap between inner pipe and outer pipe imports Ar, N2 or air to cool the spray lance. Spray lance
is depletion type. It is imbedded into refractory layers when constructing furnace. It is burned up during the
period of smelting synchronizing with furnace lining. The blown oxygen is used to heat carbon oxide. Blown
argon is used to strong convection agitation. The blown nitrogen is used to alloy when producing high nitrogen
alloy. Lots of metal nitride are saved during the production process of 21-4N kinds of steel. For example, the amount of chromium nitride is reduced and cost of production is saved a lot.
The furnace body is built by magnesiacalcium brick, chrome magnesium brick or magnesium dolomite brick.
Higher quality of electric smelting chrome magnesium brick is used around the spray lance to
bear scour of high temperature and molten steel.Removable furnace lid is built with chrome magnesium brick or
alumina-magnesia brick. It also can be made by heat-resistant concrete.
Dimensional proportion of furnace hearth is pool depth: inside diameter:
total furnace height = 1:2:3. In the situation of furnace tilting forwards a certain angle, the primary molten steel
is poured into by |
