According to SMS group, the project entailed replacement of the degasser’s vacuum pump and improvements to the vacuum lock system. The project is intended to increase plant availability and enhance steel quality. 

“Thanks to the modernization of the vacuum system, China Steel Corp. is now able to use the plant without interruption at significantly higher condensate cooling water temperatures of up to 38°C. Also, the suction capacity of the vacuum pump has been significantly increased. Now, final pressures of less than 1 mbar can be reached in shorter evacuation times,” SMS group said.
