[0001] The utility model relates to the technical field of spheroidization treatment, in particular to a bearing steel wire accelerated spheroidization treatment device. Background Art

[0002] Spheroidizing annealing is one of the basic ways to improve the structure and performance of steel. The main purpose of spheroidizing annealing is to spheroidize the carbides in the microstructure of steel materials, reduce the hardness of the materials, improve the plasticity of the materials, reduce the deformation resistance of the materials, and make the materials easy to plastically process. Bearing steel wire is mainly used to manufacture rolling elements or rings of rolling bearings. The key is to select the appropriate spheroidizing annealing process;

[0003] Patent No. CN220537854U discloses a continuous spheroidizing annealing device for bearing steel wire, including a shell, a fuel pipeline interface and a high-speed burner, wherein the fuel pipeline interface and the high-speed burner are both arranged on the side wall of the shell, and the bottom and top of the side wall of the shell are respectively provided with a circulating air inlet pipe and a circulating air outlet pipe; a motor is fixedly provided at the bottom of the shell, and the output end of the motor extends to the interior of the shell and is fixedly provided with a rotating column, and the column wall of the rotating column is fixedly provided with a plurality of evenly distributed hanging rods, and the rod wall of the hanging rod is provided with a plurality of groups of evenly distributed clamping mechanisms; an opening is provided on one side of the shell, and a shell cover is provided at the opening. The utility model can make the bearing steel wire rotate and spheroidize anneal inside the shell, thereby improving the uniformity of the spheroidizing annealing of the bearing steel wire, ensuring the quality of product use, and at the same time improving the efficiency. When the above scheme is actually performing the annealing operation, the spring fixing the bearing steel wire will fail due to the high temperature inside the shell, and when the rotating column drives the hanging rod and the bearing steel wire to rotate, the centrifugal force may also cause the spring to fluctuate, affecting the fixing effect of the bearing steel wire, and then affecting the annealing effect of the bearing steel wire. For this reason, we propose a bearing steel wire accelerated spheroidizing treatment device. Utility Model Content
