Heat exchange rack for heat treatment furnace

The utility model discloses a heat exchange material rack for a heat treatment furnace, which is characterized in that an assembling structure is arranged to solve the problem that the assembly is inconvenient to adjust according to the height of a pit type resistance furnace, and a stabilizing structure is arranged to solve the problem that the heat exchange material rack is not stable enough when the pit type resistance furnace is lifted; the assembling blocks are clamped into the assembling grooves, then the fixing bolts are rotated to be screwed into the bolt holes, firm installation between the assembling blocks and the assembling grooves is achieved, then a plurality of connecting bases and connecting annular frames can be assembled according to actual requirements, and the requirements of well type resistance furnaces with different heights are met; by pressing a stabilizing wheel, a stabilizing frame slides to compress a stabilizing spring, then the base is put into the pit type resistance furnace, at
