Melting and
refining furnaces
|
●DC
arc furnace
|
|
|
| ● |
The Daido DC Arc Furnace was developed by joint research and development with Shin Nippon Steel Corporation and Usinor-Sacilor (France). |
| ● |
DC method reduces flicker by half and enables high -power /high-speed melting. |
| ● |
DC method also reduces various specific consumption to a great extent and enables uniform melting. |
|
|
|
|
●Ladle
furnace (LF)
|
|
|
| ● |
Under current circumstances which include JIS standards review, deterioration of scrap quality, and improvements in steel quality, the arc-furnace-to-ladle furnaces process which carries out atmospheric refining such as deoxidization, desulphurization and the reduction of non ferrous impurities has become indispensable. |
| ● |
Enables smooth matching with the continuous casting machine
(CCM), thus improving productivity of arc furnaces. |
|
|
●Argon oxygen decarburization furnace (AOD)
|
|
|
| ● |
Decarburizes stainless steel at atmospheric pressure.
Excellent productivity and economics with high recovery percentage of chrome from slag. |
|
|
|
●Vacuum
degasser
|
|
|
| ● |
Recirculates the molten steel through the vacuum tank to remove hydrogen, oxygen and nitrogen and segregate non-ferrous impurities. |
