PT Krakatau-Posco Company (PTKP), Indonesia, and SMS Siemag, Germany, have put the converter-vessel changing concept involving a 300-ton change-vessel converter, a changing car as well as highly effective environmental technology for the converter shop into operation. SMS Siemag developed the concept for the converter-vessel changing technology for PTKP and delivered the tilting gear unit for the converter, the changing car, which has a working load of 1,200 tons, and the complete X-Pact electrical and automation package.
In the new PTKP plant, the latest generation of SMS Siemag’s dry-type converter-gas dedusting technology has been deployed for the first time. This technology includes a gas-conditioning tower and a dry-type electrostatic precipitator.
The converter-vessel changing concept provides for two blowing stands with permanently installed trunnion rings, three exchangeable converter vessels, a vessel-changing car, a demolition and relining stand, a stand-by depositing station and a connecting trackway.
Converter changing takes ten hours, and can be accomplished within a regular maintenance shift at the steelworks.
