Kev txhim kho ntawm kev kho cua sov technology rau yas shredder hniav
Cov yas hniav tshuaj kho cov txheej txheem yog quenching + tempering. Raws li qhov kev nthuav dav ntawm kev siv tshuab, qhov kev kho tshuab ntawm cov hniav yuav piav tau ntau yam. Lub hnab yas shredder tib lub plhaub yuav muaj qhov sib txawv ntawm kev kho thiab kev ua haujlwm, thiab yuav muaj ntau yam ntaub ntawv. Tsim cov teebmeem txawv; cov yam ntxwv ntawm cov yas ntim quav, cov ntaub ntawv thiab cov khoom siv hlau ntim yog qhov tseem ceeb rau kev zoo, thiab cov txheej txheem no yog sib npaug zos rau kev kho cov txiab.
Nyob rau xyoo tas los no, qhov kev lag luam thaum tshav kub kub tau npaj siab tias cov txheej txheem nitriding tau decompose microcracks, nce lub thickness ntawm lub nitriding txheej, thiab muaj txheej seem ntawm cov quav hniav, uas ua rau lub neej ntawm cov hniav. Cov hniav ua ke nrog cov ntsev da dej sulphur-nitrogen muaj qhov zoo ntawm kev ua haujlwm, kev tiv thaiv kev ua kom tsis muaj zog, kev tiv thaiv kev kub, thiab kev ua hauj lwm lub neej yog ob npaug.
Los ntawm kev ntsuam xyuas cov txheej txheem cua kub txheej hauv cov hniav, cov khoom siv sib txawv thiab kev kho cua sov yuav pab txhim kho kev ua tau zoo ntawm cov yas hniav thiab ua kom zoo dua qub; txoj kev txhim kho cov kev coj ua yog kom muab cov txheej txheem cov tshuaj tua hluavtaws coj los ua ke nrog cov txheej txheem kev kho cov txheej txheem los txhim kho cov cuab yeej hluav taws xob thiab kev ua haujlwm hnyav. ; carbonitriding xyaw nrog pa quenching thiab tempering xyum, tuaj yeem ua tau yooj yim dua hardness, nce qhov tob ntawm lub txheej hardened, thiab txhim kho cov stabilization tempering thiab corrosion resistant, yog li ntawd tus hniav tau zoo kub kho kho. Tib lub sij hawm, qhov zoo ntawm qhov zoo thiab kev ua tau zoo heev.
Kev hloov ua kom muaj peev xwm ua kom lub zog tawv ntawm cov yas pulverizer hniav thiab txhim kho lub neej kev ua haujlwm; tom qab cov hlau tau raug ua rau carburizing -11040 ~ 1150 ° C quenching - 550 ° C tempering ob zaug thiab lwm cov txheej txheem kev kho cua sov, qhov hardness tuaj yeem ncav cuag HRC56 ~ 61, zoo tib yam Lub neej ntawm quenching zeb hniav yog nce ntawm 1.8 mus rau 3.0 sij hawm. Nqus cov khoom sib dhos thiab cov ion carburising yog cov cuab yeej tsim tawm hauv 20 lub xyoo dhau los. Cov cuab yeej muaj cov yam ntxwv ntawm kev ceev nrawm ceev ceev, cov teeb meem infiltration teeb, kev ua kom pom zoo thiab cov me nyuam deformation ntawm cov hniav. Nws yuav ua si ib qho tseem ceeb rau txoj haujlwm nyob rau yav tom ntej kev kho mob ntawm cov khoom me me. Tseem ceeb heev.
Muaj ntau txoj hau kev rau nitriding, xws li ion nitriding, carbonitriding, oxygen-nitrogen osmosis, sulfur-nitrogen osmosis, thiab sulfur-carbon nitrogen, oxygen-nitrogen ternary osmosis. Lub hnab yas tau yooj yim kho nitride, cov adaptability muaj zog thiab cov me nyuam deformation ntawm lub workpiece, tshwj xeeb tshaj yog tsim rau qhov kev txhawb zog ntawm cov xim me me, thiab cov nitride txheej muaj kev sib zog, kev coj zoo thiab ua haujlwm zoo tiv thaiv.
Cov kev kho mob nitriding yuav hloov tau cov kev kho kom sov thiab kub ntawm cov hniav ua los ntawm H13 hlau. Lub zog ntawm cov hniav tom qab kev kho qhov dej saum nruab ntug yog siab li HRC65-70, thiab qhov nyuaj ntawm cov tub ntxhais muaj tsawg thiab lub toughness zoo, yog li ntawd cov hniav tau zoo meej txhua yam khoom siv.
