分析了型砂性能在线检测技术与ＩＳＯ－９０００标准系列的关系，并分析了国外八家厂商所生产的湿型砂性能在线检测仪器的结构原理和主要功能。分析表明，在各种湿型砂性能在线检测仪器中，紧实率都是必测项目；在有关型砂强度的检测方面，目前趋向于测量砂样的剪切强度，并与变形量的测试相结合，更能反映高密度砂型对型砂性能的实际要求。预计在今后５～１０年内，型砂性能在线检测仪器将在我国和世界范围内得到广泛的应用。
The relationship between on-line testing technology of sand properties and ISO-9000 standard series was analyzed. The structural principle and main functions of on-line wet testing equipment produced by eight foreign companies were analyzed. The analysis shows that in a variety of wet sand performance on-line testing equipment, the compaction rate is a must-test items; in the detection of sand-related strength, the current tend to measure the shear strength of sand samples, and combined with the deformation test , Better reflect the actual requirements of high-density sand on the performance of sand. It is estimated that in the next 5 ~ 10 years, on-line testing equipment for sand performance will be widely used in our country and in the world.
