Description

Известные дeфop иpyeмыe железо-кобальт-вольфрамовые сплавы не обладают достаточно высомими магнитными свойствами.Known deefer pyremye iron-cobalt-tungsten alloys do not have sufficiently high magnetic properties.

Описываемый силав на железной основе дл  роторов гистерезисных двигателей, содержащий кобальт, вольфрам и марганец, обладает высокими магнитными, в том числе гистерезисными, свойствами.The described iron-based force for rotors of hysteresis engines containing cobalt, tungsten and manganese has high magnetic, including hysteresis, properties.

Достигаетс  это изменением состава сплава, заключающимс  в снижении содержани  в нем вольфрама при одновременном введении в его состав кобальта, кремни , марганца и углерода.This is achieved by changing the composition of the alloy, which consists in reducing the content of tungsten in it while simultaneously adding cobalt, silicon, manganese, and carbon to its composition.

Сплав содержит 12%кобальта, 14% вольфрама, до 0,05% углерода, до 0,4% кремни , до 0,3% марганца, остальное - железо.The alloy contains 12% cobalt, 14% tungsten, up to 0.05% carbon, up to 0.4% silicon, up to 0.3% manganese, the rest is iron.

Магнитные свойства сплава повышаютс  в случае надлежащей его термической и механической обработки. Рекомендуетс  подвергать сплав гор чей прокатке до толщины 1,5-3,0 мм, затем закалке с 1200°, последующей холодной прокатке с обжатием в 40-60% и заключительному отпуску при 650-750°.The magnetic properties of the alloy are enhanced in the case of proper thermal and mechanical processing. It is recommended that the alloy be hot rolled to a thickness of 1.5-3.0 mm, then quenched from 1200 °, followed by cold rolling with a reduction in 40-60% and final tempering at 650-750 °.

После такой обработки сплав обладает следующими гистерезисиыми свойствами: коэффициеит выпуклости петли гистерезиса - 0,5,-0,6; удельные гистерезисные потери на 1 эрстед - 2000 -- 2500 эрг/см эр,After this treatment, the alloy has the following hysteresis properties: the coefficient of convexity of the hysteresis loop is 0.5, -0.6; specific hysteresis loss per 1 oersted - 2000 - 2500 erg / cm er,

Сплав выпускаетс  в виде холоднокатаного листа и предназначаетс  дл  изготовлени  активной част роторов гистерезисных двигателей с малыми (30-40 эр) рабочими пол ми. Сплав с успехом может заменить примен емые в насто щее врем  дл  этих же целей значительно более дорогие железо-кобальт-ванадиевые сплавь, содержащие до 53% кобальта. № 137947 2 Предмет изобретени  Сплав а железной основе дл  роторов гистерезисных двигателей, содержащий кобальт, вольфрам и марганец, отличающийс  тем, что, с целью повыщени  гистерезисных свойств, в его состав ввод т (в %): кобальта12, вольфрама14, углеродадо 0,05, кремни до 0,4, марганцадо 0,3, железо - остальноеThe alloy is produced in the form of cold-rolled sheet and is intended for the manufacture of the active part of the rotors of hysteresis motors with small (30-40 er) working fields. An alloy can successfully replace the much more expensive iron – cobalt – vanadium alloy used for these purposes, containing up to 53% cobalt. No. 137947 2 Subject of the invention Alloy on iron base for rotors of hysteresis engines, containing cobalt, tungsten and manganese, characterized in that, in order to increase hysteresis properties, cobalt 12, tungsten 14, carbonado 0.05 , silicon up to 0.4, manganese 0.3, iron - the rest
