ZXJ-2铸铁性能检测仪由集成电路和晶体管组成,是一台结构合理、体积小、重量轻、携带方便,适宜于生产现场使用的高精度仪器。它具有测定超声波在金属材料中的传播速度、测量金属和非金属材料的厚度,以及探测金属材料的内部缺陷等功能。经过杭州市机械研究所、杭州汽车制造厂、杭州机床厂共同试验证明,该仪器可测超声波在球墨铸铁、灰铸铁等中传播的速度,即可评定其球化等级、预测抗拉强度、延伸率、硬度等机械性能。是铸造生产中检测和控制铸件质量的重要测试设备。根据超声波速度能判定铸铁球化等级和强度性能的原理是:超声波在材料中的传播速度取决于材料的声学性质。在均质材料中超声波速度是恒定的,当在 ZXJ-2 cast iron performance tester consists of integrated circuits and transistors, is a reasonable structure, small size, light weight, easy to carry, suitable for use at the scene of production of high-precision instruments. It has the function of measuring the propagation speed of ultrasonic waves in metal materials, measuring the thickness of metal and non-metal materials, and detecting the internal defects of metal materials. After the Hangzhou Institute of Machinery, Hangzhou Automobile Factory, Hangzhou Machine Tool Plant joint test proved that the instrument can measure the speed of ultrasonic in ductile iron, gray cast iron, etc., you can assess the ball level, predict the tensile strength, extension Rate, hardness and other mechanical properties. It is an important test equipment for testing and controlling the quality of castings in foundry production. The principle of determining the grade and strength of cast iron based on the ultrasonic velocity is that the propagation velocity of the ultrasonic wave in the material depends on the acoustic properties of the material. The ultrasonic velocity in a homogeneous material is constant when in
