SQW-A material at high temperature strength tester (high temperature molding sand strength tester, high temperature strength of the molding material tester)

Significant Scientific Achievement Award was awarded the State Economic Commission, the Electrical and Mechanical Services Department
Jointly developed by Tsinghua University, Central South University, Shenyang Research Institute of Foundry
I. Overview
This instrument is suitable inorganic non-metallic materials, the casting modeling material high temperature, room temperature determination of overall performance, but also applied to simulate the shape of the real situation of the liquid metal to the casting mold mixes high-temperature performance test.
The instrument is the use of advanced computer technology, the smart meter technology for real-time detection and control of different parameters, experimental process parameters reflect real and effective, and to achieve a fast, stable, and reliable results. The heating of the sample as well as the constant temperature process can be set with the actual process of user requirements program control, PID control, etc..
In the furnace Φ30 × 50mm cylinder specimens under test between the uprights, suffered the loads and the generated amount of deformation measured by the load sensor and the inductive displacement converted into electrical parameters, the input to the computer, the computer data processing , storage, and output data results report.
