Main cable saddle casting quality control method

The invention provides a main cable saddle casting quality control method, which comprises the following steps of: performing scale-reduction pouring according to a preset proportion to obtain a scale-reduction main cable saddle, an attached casting test plate and single casting test plates with different thicknesses, and performing heat treatment on the scale-reduction main cable saddle, the attached casting test plate and the single casting test plates; respectively sampling the reduced scale main cable saddle, the attached test plate and the singly-cast test plates with different thicknesses according to preset positions to obtain a reduced scale main cable saddle sample, an attached test sample and a singly-cast test sample; and detecting the reduced-scale main cable saddle sample, the attached casting sample and the single casting sample, comparing the mechanical properties and metallographic structure differences of all the samples, and judging whether the quality requirements are met or not.
