Technological reconstruction of circulating water treatment for converter dedusting and analysis of its effect;

Wet-type dust removal fan applied in mechanical coal cutting stope;

Application of high voltage frequency converter on the arc furnace dust removal fan;

3 Steelmaking plant of Jinan steel used domestic technology of high voltage and large power frequency transformer to adjust speed in dusting fan serving for LF refining furnace.

In this paper,the structure,work principle,performance and using effect of the wet—dusting fan are intoduced.

The paper introduces the working process and electricity saving characteristics of steel making,and puts forward the operation and application of AC frequency modulation for speed regulation used in dedusting fan of converter.

After the dedusting fan is taken on the technology of preventing wear,the service life of centrifugal impeller can be up to above two years.

The treatment system for converter dedusting water of No.

ring upped the solution to problem for introduction for Handan Iron and Steel Company first steel mill converter dedusting water handling the system making the detail, as to it s application effect making the covariance analysis, as to it s esse.
