A heat treatment rack setter is provided to secure structural stability and product reliability by preventing a crack or damage generated from a thermal shock. A rack setter(200) for putting on a thermal object includes upper frames(210,220) of a window type reaching directly with the thermal object and a supporting frame(230) of a window type extended to a lower part of the upper frame to make space on the lower part. The upper frame has consecutive rack structure intersecting with a plurality of straight lines or curves. Discontinuous rack structure is formed with the consecutive rack structure on one side of the upper frame alternately. |
