The ultimate purpose of railway steel casting production is to obtain high-quality parts that meet the requirements of product quality inspection. Product quality inspection is not only the judgment basis for the continuous optimization and adjustment of the process scheme of railway steel castings and the continuous improvement of product quality, but also an important guarantee for the products to meet the specified performance requirements and work stably in practical application.
On the basis of mastering the coupler product quality inspection standards and technical documents and drawings, Tongling branch purchased comprehensive product quality inspection equipment, monitored the whole process of the trial production coupler according to the process flow, tested and inspected the raw materials and products in the process, and tested and verified the finished coupler blank and coupler composition quality, The process production scheme corresponding to the coupler products that have passed the final inspection has greater reliability, which lays a foundation for finally passing the product quality certification of the company and the Ministry of Railways and obtaining the qualification of mass production.
