由于科学技术的发展,人们对永磁体的应用越来越广泛。现在不仅在科研、国防、通讯、电力上得到应用,而且也应用于选矿、医学、造纸、制糖等方面。我国铸造行业引入永磁体始于1972年。目前在铸造行业的砂处理中,应用永磁体的设备,已有悬挂带式永磁分选机、永磁皮带轮及旧砂再生装置等十多个品种。随着工业的发展,永磁体的应用前景将更加阔广。
Due to the development of science and technology, people use permanent magnets more and more widely. Now it is not only used in scientific research, national defense, communications and electricity, but also used in mineral processing, medicine, papermaking and sugar refining. China’s foundry industry to introduce permanent magnets began in 1972. Currently in the sand casting industry, the application of permanent magnet equipment, there are hanging belt permanent magnet sorter, permanent magnet pulley and old sand regeneration device more than 10 varieties. With the development of industry, the application prospect of permanent magnets will be more broad.
