(54) СПОСОБ ИЗГОТОВЛЕНИЯ ПОКОВОК ИЗ МАГНИТОМЯГКИХ ЖЕЛЕЗОКОБАЛЬТОВЫХ СПЛАВОВ(54) METHOD OF MANUFACTURING OF FORGINGS FROM MAGNETIC SOFT IRON-ALBALTAL ALLOYS
ff
Изобретение относитс к металлургии , в частности к изысканию способа изготовлени поковок из магнито.-м гких железокобальтовык сплавов, используемых дл изготовлени сердечников соленоидов, полюсных наконечников и т.п.The invention relates to metallurgy, in particular, to finding a method for producing forgings from soft magnetic iron-cobalt alloys used to make solenoid cores, pole pieces, and the like.
Известен способ :улучшени , магнитных свойств поковок из магнито-м гких сплавов, состо щий из гор чей прокатки, отжига при , холодной прокатки со степенью деформации 7-60% и заключительного отжига при 1100-12000с 1.The known method: improvement, magnetic properties of forgings from soft magnetic alloys, consisting of hot rolling, annealing during cold rolling with a degree of deformation of 7-60% and final annealing at 1100-12000s 1.
Поковки из железокобальтовых сплавов с высокой индукцией насыщени 50 КФ, 49КФ, изготовленные по известному способу практически изотропны .Forgings of iron-cobalt alloys with a high induction of saturation of 50 KF, 49 CF, made by a known method are almost isotropic.
Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс способ, состо щий из нагрева на температуру Э50-1150°С, деформации, отжига и охлаждени 2.The closest to the proposed technical essence and the achieved result is a method consisting of heating at a temperature of E50-1150 ° C, deformation, annealing and cooling 2.
Недостатком известного способа. вл ютс низкие магнитные свойства .The disadvantage of this method. are low magnetic properties.
Цель изобретени - повышение магнитных свойств.The purpose of the invention is to increase the magnetic properties.
Данна цель достигаетс тем, что в способе изготовление поковок из магнито-м гких железокобальтовых сплавов (типа 50 КФ, 49КФ), включающем нагрев, пластическую деформа .цию, отжиг и охлаждение, деформацию осуществл ют осадкой со степенью деформации 3-80% при 550-800°С в направлении , совпадающем с направлеto нием намагничивани поковки, а отжиг провод т при 620-700 С с последу рщим охлаждением со скоростью 70150 град/ч.This goal is achieved by the fact that in the method of manufacturing forgings from magnetically soft ferro-cobalt alloys (50KF type, 49KF type), including heating, plastic deformation, annealing and cooling, the deformation is carried out by draft with a degree of deformation of 3-80% at 550 -800 ° C in the direction coinciding with the direction of magnetization of the forging, and the annealing is carried out at 620-700 ° C with subsequent cooling at a speed of 70150 degrees / hour.
Така последовательность опера15 ций обеспечивает получение ориентировки с направлением-, совпадающей с нормалью к деформируемой поверхности , что.улучшает магнитные свойства в этом направлении. Одновре20 менно улучшает-7 магнитна микрооднородность сплава, так как уменьшаетс кристаллографическа разориентировка зерен.Such a sequence of operations provides an orientation with a direction that coincides with the normal to the deformable surface, which improves the magnetic properties in this direction. At the same time, it improves the -7 magnetic microhomogeneity of the alloy, as the crystallographic disorientation of the grains decreases.

Дл снижени уровн напр жений и твердости перед механической обработкой поковок провод т их отжиг при 620-700С, с последующим охлаждением со скоростью 70-150 град/ч. 30 Длительность выдержки при отжигеTo reduce the level of stresses and hardness, prior to machining the forgings, they are annealed at 620–700 ° C, followed by cooling at a speed of 70–150 deg / h. 30 The duration of exposure during annealing
Устанавливают из расчета 1 ч на I см толщины.Set at the rate of 1 hour per I cm of thickness.
Индукци насыщени в образцах сплава 49КФ, вырезанных из поковок, изготовленных по предлагаемому и известному способам, приведена в таблице.The induction of saturation in samples of the 49KF alloy cut from forgings made according to the proposed and known methods is given in the table.
Поковки, изгЪтовленные по предлагаемс 1у способу, проход т отжиг по режиму 700с, с последующим охлаждением со скоростью 70 и 150 град/ч.The forgings manufactured by the proposed first method are annealed in the mode of 700 s, followed by cooling at a speed of 70 and 150 deg / h.
