An apparatus for mounting a refractory component such as a turbine shroud ring segment ( 32 ) with a ceramic core ( 42 ) onto a combustion turbine engine structure ( 34 ). The ring segment has a ceramic matrix composite skin ( 40 ), and optionally, a thermal insulation layer ( 46 ). A pin ( 60 ) is inserted through a bore ( 48 ) in the core and through an attachment bar ( 54 ) with ends received in wells ( 50 ) in the core. The attachment bar may be attached to a backing member, or tophat ( 64 ), by a biasing device ( 76 ) that urges the refractory component snugly against the backing member to eliminate vibration. The backing member and refractory component have mating surfaces that may include angled sides ( 52 S, 70 ). The backing member is attached to the engine structure. Turbine shroud ring segments can be attached by this apparatus to a surrounding structure to form a shroud ring.
