由于生产的不断改进和对外贸易保证质量的要求,解决快速、准确、自动化的测试技术与仪器装备是我国铸造工业的当务之急。 国外已大量运用电子技术控制、检测合金成份、物理和力学性能,最后采用各种各样的无损探伤技术,严格控制出厂铸件的质量,从而获得用户信誉,扩大了铸件的销路。我国近年来作了不少工作,研制成功铝液炉前快速测氢仪、红外线测温仪、数字显示测温仪 Due to the continuous improvement of production and the quality assurance requirements of foreign trade, solving the rapid, accurate, and automated testing technologies and equipment and equipment is a pressing matter of our country’s foundry industry. Abroad has used a large number of electronic technology to control, detect alloy composition, physical and mechanical properties, and finally adopted a variety of non-destructive testing technology, strictly control the quality of the factory castings, thereby gaining the reputation of the user and expanding the sales of the castings. In recent years, China has done a lot of work to develop a rapid hydrogen meter, infrared thermometer, digital display thermometer
