High Efficiency Effective Energy Saving Aod Furnace - China

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 swiveling ladle.

At this time, pneumatic lance is on the surface of molten steel.

When the

furnace is back to the upright position, spray lance is submerged into the deep molten steel and begins to blow

and refine.

After refining, steel is still out from furnace lid.

  The engineering project contracting is all over the country related with more than 100 large and medium sized enterprises in more than 10 provinces, municipalities and autonomous regions.
  
  At the same time, our company supplies steel mill in many countries and regions with equipment, technical cooperation, technical exchange and joint design.
  
  What's more, environmental protection and energy saving vertical charging scrap preheating arc furnace independently developed by our company has reached the international lowest power consumption.
  
  Power consumption of scrap steel smelting is close to 300 KWH per ton, and reduce the cost $12.3 for per ton steel.
  
  Take an example of annual output 200000 tons of steel factory, power consumption and energy saving aspects increase profits $2.5 million.
  
  The electrode adjustment system is adopted Siemens technology.
  
  The electric furnace and the vertical feeding system are developed by our company independently.
  
  And we applied for a patent.
  
  Our company applied for dozens of patents over the years.
  
  We often have technical exchanges with Japan, America, Germany and other countries.
  
  We also exchange and cooperate with China Iron & Steel Research Institute and academic institutions such as University of Science and Technology Beijing, Northeastern University, Xi'an University of Architecture and Technology, Xi'an University of Technology, etc.
  
  Thus, our company made a breakthrough in multiple key technology of metallurgical equipment.
  
  Now, we are applying for national energy conservation and scientific research funds.
  
  The concept of our company is "Establishing the industry credibility; Win the customers trust.
