AOD furnace (argon oxygen decarburization process) is advanced technology for producing ULC stainless steel and pure high quality alloy-steel casting. It can   be used for smelting ULC (C<3%) and ULS (S<0.003%) steel. The primary degumming steel molten in electrical arc furnace or intermediate frequency furnace is injected AOD furnace by steel ladle. The O2, Ar or N2 gas mixture during smelting will decarburize for steel, meanwhile will be put reducing agent, desulfurization agent, ferroalloy, coolant, etc. to adjust the molten steel composition. And smelt the qualified stainless steel products.

AOD furnace will produce large volume dust during against steel, smelting or tapping.  For how to collect the dust for all process and deal with the high-temperat-ure dust, our company had designed the capture hoods and cooling methods for furnace condition. For example central suction hood roof, bilateral suction hood, mobile top suction hood, etc.

Our company give a detail explain and design selection for AOD furnace smelting condition.

Design specifications

Smoke dust arrestment rate ≥95%;

Smoke dust concentration ＜30mg/Nm3;

Countries and environment protection department establish the other relevant specifications and requirements.
