Description

СПОСОБ ОБЕЗЖИРИВАНИЯ МЕТАЛЛИЧЕСКОЙ СТРУЖКИMETHOD OF METAL CHIP DEGREASING

1one

Изоб|рете)Н.ие относитс  к области металлургии , в часТНости ж технике предварительной П01д1готов1КИ .металлической стружки к брикетироваиию, панкетированию и переплаву.Inventory. In the field of metallurgy, in particular, the technique of preliminary metal chips for briquetting, panketing and remelting.

Известе  опособ обезжиривани  металличеоКОЙ стружки цри нагреве в газовой атмосфере , например во вра1ща1Ю:Щихс  ба1раба«ных печах, по которому стр{}Жку загружают в печь и одновремавно в лечь подают воздух, а образующиес  тазы отвод т из печи. Одиако от1мечаетс  высокий yraip ст)руж-ки (до lOVo) и выброс в атмосферу томсичных веществ - прадуктоВ ого)рани  /масла.It is known that metal chips should be degreased when heated in a gaseous atmosphere, for example, in a rotary: Schichs furnace shop, through which the furnace is loaded into the furnace and at the same time air is fed into the cavity and the formed pellets are removed from the furnace. Odiaco has a high yraip st) rifle (up to lOVo) and an emission of tomsic substances into the atmosphere — praduttow th) wounds / oils.

Предложенный опособ отличаетс  тем, что обезжиривание 1ароизвод. т в атмосфере ийертного газа, а пары масла и влаги колденоируют в холодиль1НИ1ке. Это .исключает угар стружки и снижает выброс токсичных веществ в атмосфе|ру.The proposed method is characterized in that the degreasing is a derivative. t in an ihert gas atmosphere, and oil and moisture vapor are codenoated in an icebox. This eliminates the waste of chips and reduces the release of toxic substances into the atmosphere.

Приме)р. Замасл нную стружку напревают в присутствии азота при 200°С. Образующиес  пары коиде слируют в холодильни.ке. Полученный конденсат ие и.меет примесей твердых частиц и ха.рактериэуето  «инематической в зкостью при 50°С, равной 23,6 ест, температу(рой вспьиплки 183°С, кислотным числам 0,58 мг/г, кислой реакцией водной выт жки зольностью 0, и содержит 5,0% воды. При этом не на-блюдаетс  увеличени  окисленной Металлической стружки.Example. Oily chips are sprayed in the presence of nitrogen at 200 ° C. The resulting pairs of coide are drained in a refrigerator. The resulting condensate has impurities of solid particles and has an “inmatic viscosity at 50 ° C, equal to 23.6 eats, temperature (swarm 183 ° C, acid numbers 0.58 mg / g, acidic reaction of water extract the ash content is 0, and contains 5.0% of water, while no increase in oxidized metal chips is observed.

Предмет изобретени Subject invention

Опособ обезжиривани  1металличе ской струшки при нашраве в газовой атмосфере, отличающийс  тем, чпо, с целью исключени  угара стружки и .масла и снижен.и  выброса токсичных веществ в атмосферу, обезжиривание производ т в атмосфе|ре инертного газа, а пары масла и влаги кО|Нде«сируют в холодильнике .The method of degreasing metal flakes under gas in the atmosphere of the atmosphere, which is different in that, in order to eliminate shavings of oil and oil, and reduce and release toxic substances into the atmosphere, degreasing is carried out in an atmosphere of inert gas, and oil and moisture vapor are removed. | Nde "sirut in the fridge.
