[0002] The rapid development of the heavy-duty gas turbine industry has placed increasingly higher demands on the efficiency of gas turbines. However, the clearance between the turbine blade tip and the casing is one of the significant factors affecting the overall efficiency of the gas turbine and increasing gas consumption. In actual production, due to excessive blade operation and material degradation, large quantities of materials often require post-weld heat treatment. Traditional heat treatment equipment cannot achieve batch heat treatment, resulting in low efficiency and unstable fixing equipment. Therefore, it is necessary to design a material rack to achieve effective fixing and batch heat treatment. Utility Model Content
