The invention discloses a vertical rack. The vertical rack is used for containing aluminum rolls for heat treatment. The vertical rack comprises at least one supporting disc arranged horizontally, all the supporting discs are arranged in the vertical direction, supporting frames are arranged between the adjacent supporting discs, the supporting discs are provided with containing holes for containing the ends of sleeves of the aluminum rolls, and multiple flow cells are arranged on the upper side portions of the supporting discs. According to the vertical rack, the problem that the annealed aluminum rolls are vertically put and supported in a bell furnace is solved, and the aluminum rolls are annealed in the bell furnace; by means of gas flow passageways between the end faces of the aluminum rolls and supporting plates, the end faces of the aluminum rolls are more uniformly heated, and axial and radial transfer of heat is facilitated; the bell furnace is only provided with one circulation fan on a coil base, t
