PROBLEM TO BE SOLVED: To provide a plate liner structure of an ore receiving metal material which suppresses the thermal deformation of a plate liner and need not replace the plate liner itself even when a tensile chain fitting part is broken. SOLUTION: In the plate liner of an ore receiving metal material 5 in a blast furnace, the plate liner 1 is formed of plates 2 and 3 that are divided into a plurality of stages in the vertical direction, joining portions of the divided plates 2 and 3 placed with a clearance therebetween, and tightened by bolts 4 in a freely deformable manner. A cone-shaped hole 6 in which a fitting part of a tensile chain fitting metal material 8 to fit a tensile chain 7 to be connected to a fixing piece 11 of a skin of the blast furnace is inserted, can be provided in the plate liner 1.
