Mexican Steel Producer Orders Vacuum Degassing Plant
Siemens Metals Technologies received an order from Mexican steel producer Altos Hornos de Mexico, S.A.B. de C.V. (AHMSA) to supply a 150-ton, twin RH vacuum degassing plant with mechanical vacuum pumps for converter Steel Works # 2 in Monclova. It will be able to handle 50 charges per day, which is the equivalent of about 2 million metric tons of liquid steel per year. The new plant, which is scheduled for commissioning in October 2015, will allow AHMSA to produce steels with the very low hydrogen content required for applications in the oil and gas industry. The main functions of RH degassing plants are the removal of hydrogen, forced decarburization and the chemical heating of the liquid steel, which is processed under vacuum conditions with the injection of oxygen.
