Coefficient yekuwedzera kwechaiyo simbi pombi

Tarisa iyo nzira inogona kushandiswa muchoto chekuvharisa mvura ine sipo kupukuta yega yega majoini mutswe, kuona kana uchimhanyisa gasi;nzvimbo idzo gasi rinowanzo pinda muchoto chekubira uye nekuisa chubhu panzvimbo, nzvimbo ino zvisimbiso zvinonyanya kutambudzika kusakara uye kubvaruka, Gara uchitarisa kazhinji kuchinja.Yakaunzwa pamberi pemupumburu wekugadzira chaiyo simbi pretreatment process scheme;Kuongororwa kweiyo normalizing tembiricha, kubata nguva uye kutonhora pesvedzero yeiyo raw material chubhu microstructure uye michina zvivakwa;kuona iyo yakajairwa normalizing muitiro chaiyo simbi machubhu: kupisa tembiricha (890 ± 10) ℃, kutonhora kwemhepo mushure mekubata 6min yakapindirana.Yakajairika normalizing process inogona kubviswa zvachose chaiyo simbi Widmanstaten kuti ienderane nekusimba kwegoho uye kusimba kwesimba kunonzwisisika goho reshiyo σS / bσ≤0.78, elongation 5δ≥30%, uye yakagadziridzwa zvakanyanya kutonhora kuumbwa kudzivirira mutswe wakagadzirwa nechando.Kuwedzera coefficient inogona kuratidzwa nehuwandu kana kureba kunowanzo kuratidzwa maererano nehurefu.

Density ndiko kuwanda kwehuwandu hwezvinhu payuniti vhoriyamu yechinhu, iyo unit ikg / m3 kana 1b / in3.Tensile residual stress kunyanya kubva kune tensile residual stress inogadzirwa mumudziyo panguva yewelding process.Parizvino, inoshandiswa zvakanyanya muinjiniya annealing kurapwa kuti ibvise kushushikana kwasara mushure mekupisa kutonhora, uye kutonhora mushure mewelding residual stress inzira yakakosha, nzira iyi kutambisa simba uye nyore kuve nekunyanya welding kusara kunetseka.Post weld heat treatment ndiyo tekinoroji nyowani yekubvisa kushushikana kwasara.Usati welding precision simbi pombi preheated kune tembiricha kupisa kurapwa uye welding process weldment yakaramba ichidziya kuchengetedza tembiricha iyi, kushandiswa kwewelding kunopera donje insulation insulation inobvumidzwa kutonhora zvishoma nezvishoma.Kudzima pombi yesimbi kuwedzera simba uye kuoma, asi kuderedza plastiki yavo.Kudzima kuomesa agent inowanzoshandiswa mumvura, mafuta, munyu uye alkali mhinduro nezvimwe zvakadaro.Ichange iine simbi yakanyoroveswa yakaomeswa nesimbi chaiyo ichidziiswazve kune imwe tembiricha, uyezve imwe nzira yekutonhodza inozivikanwa sekudziya.Chinangwa chayo ndechekubvisa kushushikana kwemukati kunokonzerwa nekudzima kudzikisa kuoma uye brittleness, kuitira kuti uwane inodiwa mechanical properties.Tempering points yakakwira-tembiricha kudzikama, kudzikama uye kudzikira tembiricha kudziyisa mapoka matatu.Multi-quenching uye tempering, normalizing inoshandiswa pamwe chete.Pashure quenching uye tempering quenching nzira inonzi quenching.
