   Sammanfattning : Water modelling investigations of pressure change at tuyere tip or back attack and wear of H3B03 disks, as well as high temperature modelling wear tests of BOF refractory using single- or double-tuyere and Ar or N2 gas, have been carried out to study mechanisms for mechanical wear of the refractory for BOF stirring tuyeres and plugs. A new nominal Mach number, M*', was defined and adopted as the criterion for correlating test data. LÄS MER
