выдержкой 30 час и последующим иагревом до 900° или 1000° С с выдержкой при этих температурах в течение 2 час.exposure for 30 hours and subsequent ignition to 900 ° or 1000 ° C with exposure at these temperatures for 2 hours.
Свойства электротехнической стали характеризуютс следующими значени ми:The properties of electrical steel are characterized by the following values:
Форм у Л а изобретен и The form in LA is invented and
Способ термической обработки электротехнической стали, включающий обезуглероживающий и рафинирующий отжиги гор чека таиого подката и окончательный отжиг холоднокатаных листов, отличающийс тем, что, с целью улучщени магнитных свойств стали, рафинирующий отжиг осуществл ют при температуре 1020-1300 С в течение 2-10 час и окончательный отжиг ступеи ми при 500-600° С с выдержкой 10- 50 час с последующим подъемом температуры до 850-1000° С и выдержкой в течение 2 час.The method of heat treatment of electrical steel, including decarburizing and refining annealing of hot rolled strip and final annealing of cold rolled sheets, characterized in that, in order to improve the magnetic properties of steel, refining annealing is performed at a temperature of 1020-1300 C for 2-10 hours the final annealing with steps at 500–600 ° C with a holding time of 10–50 h, followed by raising the temperature to 850–1000 ° C and holding for 2 h.
