Production of high-magnesia fluxes and extension of converter-lining life: Part 2

Research on the use of high-magnesia fluxes in (160?C400)-t oxygen converters reveals the influence of the smelting parameters, the composition of the metal and the slag, and the working temperature on the assimilation of MgO from the flux. Slag formation and the removal of sulfur and phosphorus are considered, as well as the influence of magnesia slags on lining wear in the converter.     

Experience Gained in the Service of a Zonal Lining for Converters at the Magnitogorskii Iron-and-Steel Works Joint-Stock Company

A brief report on the execution of a step of a program on improving durability of the refractory converter lining at the MISW JSC in 2001 is presented. The use of refractory components PUPK-1 (available from Kombinat Magnezit) and refractory components available from Meierton Co. in various campaigns is discussed.     

Production of high-magnesia fluxes and extension of converter-lining life: Part 1

A new class of slag-forming materials has been developed: magnesia fluxes with up to 90% MgO. Their mineralogical composition and physicomechanical properties are investigated. The solution of fluxes in synthetic and converter slag melts is studied as a function of their structural properties and chemical composition. A production technology for such fluxes has been developed and introduced.
