Mukurapa kwekupisa kwekugadzira, nekuda kwesimba guru rehuni hwekupisa uye nguva yakareba yekudzivirira, kushandiswa kwesimba kwakakura mubasa rose, munguva yakareba, nzira yekuchengetedza simba mukupisa kwekupisa kwekugadzira kwave kuri dambudziko rakaoma.

Iyo inonzi "zero insulation" quenching, ndiko kunongedza kuforoma kudziyisa, pamusoro wayo uye musimboti kusvika quenching kudziyisa tembiricha, hapana insulation, pakarepo quenching kutonhora process.According yechinyakare austenitic dzidziso, forging inofanira kuva refu insulation nguva mukupisa muitiro, kuitira kuti apedze nucleation uye kukura kwe austenisoal hosha yezviyo, kuparara kwezviyo uye kuparara kwezviyo. of austenitic.The ikozvino quenching uye kupisa tekinoroji forgings inobudiswa pasi kutungamirirwa dzidziso iyi.Kuenzaniswa nezvino quenching muitiro, "zero kupisa kuchengetedza" quenching inoponesa nguva yekudzivirira kupisa kunodiwa nehomogenization of austenitic chimiro, kwete chete inogona kuchengetedza 20% -30% yesimba, inovandudza kugadzirwa kwe302%, kuvandudza kugadzirwa kunogonawo kuderedza 302%. oxidation, decarbonization, deformation uye zvichingodaro, izvo zvinobatsira pakuvandudzwa kwemhando yechigadzirwa.

Kana kabhoni simbi uye yakaderera alloy simbi inopisa kuAc1 kana Ac2, iyo homogenization process ye austenite uye kupera kwe carbides mu pearlite inokurumidza.Kana saizi yesimbi iri yechikamu chakaonda chikamu, kuverenga kwekupisa nguva hakudi kufunga nezve thermal insulation, ndiko kuti, kuzadzisa zero thermal insulation kana ukobvu hwe4 kana chidimbu chesimbi chinodzima. 100mm, kupisa muchoto chemhepo, tembiricha yepasi nepakati inenge yasvika panguva imwe chete, saka nguva yayo yakafanana inogona kufuratirwa, kana ichienzaniswa neyechinyakare kugadzirwa maitiro (r = aD) nehombe yekudziya coefficient, inogona kuderedzwa neinenge 20% -25% quenching kupisa nguva.

Ongororo yedzidziso uye mhedzisiro yekuyedza inoratidza kuti zvinogoneka kutora "zero insulation" mukudzima uye normalizing kupisa kwesimbi yezvimiro. Kunyanya, 45, 45 mn2 kabhoni yakarongeka simbi kana imwechete element alloy simbi yekugadzira, kushandiswa kwe "zero insulation" maitiro anogona kuve nechokwadi chemichina yezvinodikanwa; "zero insulation" kupisa kupfuura kupisa kwechinyakare kunogona kuchengetedza kupisa nguva ye50%, iyo yakazara simba rekuchengetedza ye10% -15%, inovandudza kushanda kwe20% -30%, panguva imwechete "zero insulation" yekudzima nzira inobatsira kunatsa zviyo, kuvandudza simba.
