Nyeredzi kabhoni simbi pombi imwe yemapombi eboiler anoshandiswa musimba rekudyara boiler pombi.Mazhinji eaya machubhu anoshanda pasi pekushisa kwakanyanya uye kumanikidzwa, saka, pane zvimwe zvinodikanwa pamichina yehunyoro kabhoni simbi pombi, welding kuita uye kuita kwesangano, mukuwedzera kune inodiwa kuve nekamuri yakanaka tembiricha uye tembiricha yepamusoro michina, aya machubhu. inoda kutonhora kwakawanda, saka, izvo zvinodikanwa zvemachubhu aya zvinofanirwa kuve nepamusoro ductility uye kuoma.Cold processing program yakakosha kune boiler pombi yekumisikidza maitiro, asi mukutonhora kukotama maitiro, kuomesa basa kuchavewo kwemwongo.Cold-formed general, kune nzira mbiri, imwe haina kutonhora-yakaumbwa isati yatanga kupisa inotonhora inozvitutumadza preheating.Preheated kazhinji mazhenje kubikwa, preheat tembiricha zvine simba nemushandisi kuti abate, uye mushure mekukotama kwese kutonhora, uye pasina kupisa maitiro.Nokudaro, kutonhora kwekugadzirisa kupukunyuka kunowanzounza kuchinja kwezvigadzirwa zvemichina uye kuchinja mukushanda kwemasangano, izvo zvakaumba pombi inogona kujeka mubasa rekuita inishuwarenzi kuti ive chimwe chezvikonzero zvekukundikana.Inonyatsozivikanwa, kutonhora kukotama mushure mekuoma kunokonzera kusimba kwechubhu yesimbi uye kuwedzera kwekuoma, ductility uye kuoma kwakaderera, chikonzero chakatyoka kristaro uye padhuze nelatisi yakasimba torsional SUI yemhangura inotsvedza ndege, ichiwedzera kutsvedza kuramba saka ramba uchienderera. kutsvedza kunonetsa kuita.Uyezve, nekuwedzera kwechiyero che deformation, basa rekuomesera bvudzi goridhe rakawedzera.

Kune yakapfava kabhoni simbi pombi, kutonhora kugadziridzwa (kusanganisira kutonhora-kuumbwa kusati kwadziya-kumusoro) kuchava nemhedzisiro yakakura pakurongeka kwepombi yesimbi, zvinotungamira zvakananga mukuputsika kwakakomba.Naizvozvo, iyo sangano inofanirwa kuve inotonhora-yakaumbwa kabhoni simbi pombi pombi yekugadzirisa matanho ediki.

Kugadzira kudziya-up kunonzwisisika

Zvinoenderana neakasiyana masimbi anopindura uye tembiricha yekudzoreredza tembiricha, kugadzira iyo chaiyo preheat tembiricha uye maitiro ekushanda, uye kwete nebofu kupisa, isingapfuure Ac] chikamu chekuchinja nzvimbo, iyo inodziya-up inogona kudzivirira kudonha kwekona kana kuumbwa kweiyo micro. -kutsemuka.Nekudaro, iyo data inoratidza kuti iyo yakaderera-kabhoni simbi mu300. C nezve apo pachava ne "blue brittle" pane kuoma kwepurasitiki kunoderera.Saizvozvo, kuitira kuti zviwedzere kutsetseka kune deformation nhanho, iyo preheating tembiricha pa400 ~ 500. C yekunhuhwirira inonyanya kukodzera.Panguva imwecheteyo, teerera kune shangu, tauro, kutonhora zvakanyanya kubhenda deformation kumhanya;too fast.Kuvandudza kukurumidza kwezhizha-yakaita, iyo yakakwirira tembiricha ye "Blue marrow".

Kupisa kurapwa mushure mekukotama kwemambure

Recrystallization annealing, uye kubviswa kweiyo mechanical properties nekuda kwekuoma kwebasa rekuchinja maererano nemhando dzakasiyana-siyana uye mamiriro ekushanda e workpiece inofanira kuitwa pane workpiece mushure mekushanda kunotonhora.640 inoshandiswa kune pombi yesimbi ye20# annealing, inogona kuve yakanaka yekuzorodza kushushikana uye kudzoreredza kwemakanika zvinhu.Asi zvinofanirwa kucherechedzwa kuti, mune inotevera kutonhora maitiro, zvinodikanwa kunonoka kutonhora, - senge kutonhora kutonhora hakugone kupfuura 6 kusvika 8. C / mvura.

Muchidimbu, munyoro kabhoni simbi pombi mukutonhora kupeta muitiro (kusanganisira kudziya-kumusoro), kukonzeresa kukuru pakuita kwesangano kuve pombi yesimbi, mhedzisiro yakananga yekuputsika kwakakomba kukundikana.Preheat iyo inotonhora-yakaumbwa kabhoni simbi pombi inofanira kunyatsoenderana nemaitiro ekuuraya, mushure mekutonhora-yakaumbwa kunofanirwa kudzivirira mutsetse annealing kupisa kurapwa.
