This invention relates to the field of material mechanical property testing technology, specifically to a method and system for determining the strength grade of planted concrete using recycled aggregate. The method includes the following steps: quantifying the multi-level loading response characteristics and deformation compatibility of planted concrete; identifying damage sequence and dividing waveband propagation paths; statistically analyzing aggregate frequency to assess weight and analyze hierarchical strength; screening associated measurement paths through key nodes; calculating extension values ​​and prioritizing them; and obtaining a concrete strength propagation aggregation information table. In this invention, by extracting response data from the loading stage, multi-level stress states and damage trajectories are identified, achieving accurate characterization of deformation compatibility and strength evolution, improving damage evolution identification capabilities, associating recycled aggregate types with damage stages, enhancing the ability to assess the impact on structural performance, identifying key damage nodes and triggering relationships, optimizing strength measurement paths, and solving the problems of insufficient measurement accuracy and incomplete understanding of structural response under complex working conditions.

This utility model relates to the field of tellurium ingot casting technology, and specifically discloses a tellurium ingot casting device, including a furnace, a chute, a casting sump, and a casting machine platform. The furnace includes a crucible, a cover plate, insulating bricks, a heating device, a thermocouple, a first outer shell, a support, a rotating shaft, a connecting shaft, a leak detection port, and a pressure cap. The furnace is mounted on the support and connected by the rotating shaft. The cover plate is connected to the first outer shell through the connecting shaft. The first outer shell is made of stainless steel. The leak detection port is located on the side of the furnace near the chute. The crucible is made of silicon carbide graphite and is fixed to the first outer shell by the pressure cap. The insulating bricks and the heating device are located between the crucible and the first outer shell. This utility model adopts a two-stage zoned temperature-controlled melting and impurity removal method from bottom to top. Impurities easily float to the surface and solidify, resulting in good stratification with the molten tellurium. The impurity removal effect is good, the operation is simple, and the tellurium yield is high. The entire operation process is controlled by PLC, with a high degree of automation, avoiding frequent contact between operators and the high-temperature molten material, and creating a friendly working environment.
