AOD (argon oxygen decarburization) Furnace

AOD (argon oxygen decarburization) Furnace 3T-120T Argon Oxygen Decarburization Furnace and Ladle Refining Furnace with 8000 KG Weight

AOD argon oxygen decarburization furnace is a kind of Ladle Refining Furnace, which is characterized by side-blowing oxygen through the bottom tuyere with an immersion way. When the tuyere center is blown in with oxygen, argon and mixed gas of nitrogen, the proportion of argen and oxygen should be adjusted, then, it can achieve the purpose of decarburizing and retaining of chrome. Argon and nitrogen are used as cooling gas for tuyere ring to extend the life of tuyere. It can get the best operation by controlling the flow of the tuyere ring. And the flow of the tuyere center and tuyere ring can be controlled in master-control room.

The burning loss of tuyere, refractories and chrome is influenced greatly by the temperature of molten steel. So we can offer a special online temperature measuring system to buyers.

We adopt secondary combustion of top lance technology. It can increase the volume of cold material put into the VOD and shorten the duration of smelting, and guarantee the continuous casting for multiple furnaces at last.

We also use the charging system with a weigh on its multiple bunkers, which can be directly connected with control system of computer. Then the smelting cycle will be shortened and labor intensity will be reduced.

This equipment has a control system of intellectualized smelting process, which can decrease the consumption of all kinds of raw materials and gas during the smelting, and guarantee a stable quality of products.

New security design for smelting

It is aiming at the plugging of lance and the back-flow of molten steel which caused by electricity interruption during smelting process.

AOD series Ladle Refining Furnaces have a function to keep pressure of tuyere and contain uninterruptable power output to stop the above accidents, consequently improve the safety of smelting process.
