我所在上海自动化仪表所的协助下,自六八年以来,研制了Fe-Cr、Fe-Ni、Fe-Al等耐腐蚀软磁合金。现已使用在油、氨、空气、煤气、肼、氟利昂、蒸汽、水及海水等介质的电磁阀上,解决了原用纯铁易锈蚀卡死及多种电磁阀依靠进口的局面,填补了我国空白。 电磁阀系自动控制和自动调节系统中的常用元件,它要求所用的软磁合金具有良好的耐腐蚀性,较高的磁感应强度,较小的矫顽力,并要求一定的机械强度,以及耐磨性、可加工性、可焊性等。
With the help of Shanghai Automation Instrumentation Co., Ltd., we have developed corrosion-resistant soft magnetic alloys such as Fe-Cr, Fe-Ni and Fe-Al since 1960. Has been used in the oil, ammonia, air, gas, hydrazine, Freon, steam, water and sea water on the solenoid valve to solve the original pure iron easy rust and a variety of solenoid valve to rely on imports, to fill the My country is blank Solenoid valve automatic control and automatic adjustment system components commonly used, which requires the use of soft magnetic alloys with good corrosion resistance, high magnetic flux density, small coercive force, and requires a certain degree of mechanical strength, and resistance Grindability, workability, weldability and the like.
