Description
II
Изобретение относитс к порошков 58 металлургии, в частиости, к способам получени стального порошка.The invention relates to metallurgy powders 58, in part, to methods for producing steel powder.
Известен способ получени стального порошка, заключающийс в восстновлении окалины иизкоуглеродистых сталей газообразным или комбинированным вос; тановителем, размоле полученного спека, рассеве и сепараци порошка 1 .,A known method for producing steel powder consists in restoring the scale of low-carbon steels with gaseous or combined recovery; by the grinding agent, grinding of the obtained speca, sifting and separation of the powder 1.,
Недостатком способа вл етс высока стоимость получаемого порошка , The disadvantage of this method is the high cost of the resulting powder,
Наиболее близким к изобретению по технической сущности и достигаемому эффекту вл етс способ получени стального порошка из отходрв опиловочиых операций подшипникового производства, заключающийс в просушивании шихты при в атмосфере диссоциированного аммиака в течение 0,2-2 ч введении в шихту 3% сажи и последующего отжига в атмосфере восстановительного газа при 1050С вThe closest to the invention in technical essence and the achieved effect is the method of obtaining steel powder from waste operations of bearing production, which consists in drying the mixture when in an atmosphere of dissociated ammonia for 0.2-2 hours the introduction of 3% carbon black into the mixture and subsequent annealing in reducing gas atmosphere at 1050С
течение 1,5-2 ч, размоле спека и рассеве порошка 2.for 1.5-2 hours, grinding SPECA and sieving powder 2.
Недостатками известного способа вл ютс высока стоимость порошка, св занна с длительностью процесса восстановлени , необходимостью использовани сажи и применени осушенного и очищенного от кислорода восстановительного газа, Кроме того, известнь1й способ требует организации на подшипниковых предпри ти х раздельного сбора отходов опиловочных и шлифовальных операций и использование только отходов опиловрч-. ных опера:дий, что ограничивает строевую базу дл получени стального порошка.The disadvantages of this method are the high cost of the powder associated with the duration of the recovery process, the need to use carbon black and the use of a reducing gas that is dried from oxygen and requires a separate collection of grinding and grinding waste from bearing plants and the use of Only waste opilovrch-. operation: diy, which limits the drilling base for the production of steel powder.
Цель изобретени - снижение стоимости порошка и расширение сырьевой базы дл его получени .The purpose of the invention is to reduce the cost of the powder and expand the raw material base for its production.
