Product Description
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.

SHOO-IN (INT'L) Holding Xi'an Equipment Co., Ltd is specialized in producing electric arc furnace, refining furnace, VD, VOD vacuum casting and kinds of ferro-alloy submerged arc furnace and medium frequency furnace as well as spare parts and metallurgical equipment. It is an international metallurgical equipment engineering company, which is shared by Hong Kong international super large enterprise group SHOO-IN (ITL) holding Xi'an equipment Co., Ltd and hold by Fujian new investment management Co., Ltd. Senior management, key technical staff, line manager, installation and debugging personnel in SHOO-IN also share. The registration place is Xi'an China.
With the development of more than ten years, SHOO-IN has been a large comprehensive engineering company. The main business is domestic first-class metallurgical equipment design, production, complete design and project general contracting. There are over 100 staff which include 50 workers and 40 people for designing and administration. We also have lots of expert of high reputation as counselor group to supply solution on innovative and high technology, management, quality controlling etc. 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.
