AI Technical Summary

Technical Problem

In large anchor cups, hot-cast anchoring materials for bridge cables are prone to problems such as high porosity and uneven casting, resulting in insufficient density and affecting anchoring efficiency.

Method used

A dynamic heat preservation device is adopted, including an annular sleeve, heat preservation device, temperature sensor and control system. The temperature sensor monitors the surface temperature of the anchor cup, and the control system adjusts the heat preservation device to ensure that the anchoring material maintains a uniform temperature during the casting process. Heat distribution is controlled by heat-conducting plate and phase change material to achieve multi-stage heating or heat preservation.

Benefits of technology

It solves the problems of high porosity and uneven casting of anchoring material, improves the density and casting efficiency of anchoring material, reduces thermal stress cracks during the cooling process of castings, and significantly improves the quality of anchoring material.
