在电讯器材工业和反复磁化时功率损耗无意义的许多物理仪表中,大量采用工业纯铁(ГОСТ 3836-47)作为制造各种具有磁性的零件(电枢、膜片等)的软磁金属。根据技术条件,这样的铁若是棒材立具有不高于1.2奥斯特的娇顽力,如系板材则不应超过1奥斯特。而铁在供应状态和机械加工后其磁性通常不能满足这些要求,可以制就的铁件还得由使用厂施以退火,提高其磁性。列宁格勒М. И.加里宁工学院热外理实验室曾研究能保证工业纯铁荻得高磁性的退火规范。为了研究退火温度对铁磁性的影响,曾用棒材制了
In many applications, such as the telecommunications industry and many physical instrumentation where power loss is not significant when repetitive magnetization, industrial pure iron (ГОСТ 3836-47) is widely used as a soft magnetic metal for manufacturing various magnetic components (armatures, diaphragms, etc.). According to the technical conditions, such iron if the bar legislation has not more than 1.2 Auster’s coercive force, such as the Department of the plate should not exceed 1 Oersted. The iron in the supply state and its magnetic processing can not usually meet these requirements, can be made of iron must be annealed by the use of plant to improve its magnetic. Leningrad М. И. Kalinin Institute of Thermal Physics Laboratory has studied to ensure that the industrial iron Di Di was high magnetic annealing specifications. In order to study the influence of annealing temperature on ferromagnetism, it was made of bar material
