The characteristic of spatial distribution of plasma ion density in reaction chamber were diagnosed by a Langmuir double probe, and the effect of Ar pressure and RF power were also investigated.
The probe introduces molt en steel form the steel bath into sampling chamber during blowing.
在吹氧时，钢水会自动进入到探头的取样盒内，形成对钢水的取样。

Due to the unique ability of levitating a charged char particle in a chamber, the electrodynamic balance technique can be used to probe the combustion process of single char particle in situ.
