Riegl USA, Orlando, Fla., formed a partnership with Phoenix Refractory Technologies (PRT) to develop and offer blast furnace repair services for the steel industry using 3D digital imaging data. Under the partnership, PRT will utilize Riegl's 3D imaging equipment for enhanced determination of interior vessel lining geometry, resulting in the measurement of precise current geometry of the blast furnace interior vessel lining. It also has the ability to cross-reference this graphical data with the initial lining geometry to better coordinate the application of monolithic refractory.
