Abstract

The invention relates to a material basket used for heat treatment of an aluminum alloy profile roller hearth furnace, which comprises several split frames. The split frame includes an upper and lower two-layer truss structure. The first layer of truss structure includes two parallel and equal-length stainless steel square tubes and multiple seamless steel pipes; the second layer of truss structure includes stainless steel square tubes and multiple stainless steel round rods. , the stainless steel plate is perpendicular to the stainless steel square; the seamless steel pipe and the stainless steel round bar are staggered up and down to form several X shapes. The beneficial effects of the present invention are: the split frame as a whole adopts a truss structure, and the middle part forms a triangular structure, which has good stability, and the number of split frames can be freely assembled according to the length of aluminum alloy profiles in the actual production process, effectively reducing the rapid The overall thermal stress during the cooling process reduces deformation; in addition, the aluminum alloy profile and the stainless steel round bar are in line contact, and the stainless steel round bar has a small blocking effect on the quenching water.
