Kugadzira kuchenesainzira yekubvisa kuremara kwepamusoro kwefogi nenzira dzemakanika kana kemikari. Kuti uvandudze hutano hwepamusoro hwekugadzira, kuvandudza mamiriro ekucheka ekugadzira uye kudzivirira kuremara kwepamusoro kubva pakuwedzera, zvinotarisirwa kuchenesa pamusoro pemabhidhi uye mabheji chero nguva mukugadzirisa.
Kuti uvandudze hutano hwepamusoro hweforgings, kuvandudza mamiriro ekucheka kweforgingsuye kudzivirira kukanganisa kwepamusoro kubva pakuwedzera, kunodiwa kuchenesa nzvimbo yebhillet uyeforgingschero nguva muforging process. Steel forgingskazhinji dzinopisa pamberiforgingnebhurashi resimbi kana chishandiso chiri nyore kubvisa oxide scale. Iyo isina chinhu ine saizi yakakura yechikamu inogona kucheneswa nejekiseni remvura yekumanikidza. Zviyero pazviputi zvinotonhora zvinogona kubviswa ne pickling kana kuputika (pellets). Nonferrous alloy oxide scale ishoma, asi isati yatanga uye mushure mekugadzira kunhonga kuchenesa, kuona nenguva uye kubviswa kwehurema hwepamusoro. Kuremara kwepamusoro kwebillet kana forgings kunonyanya kusanganisira kutsemuka, kupeta, kukwenya uye inclusions. Kana zvikanganiso izvi zvikasabviswa nekufamba kwenguva, zvichava nemhedzisiro yakaipa pane inotevera yekugadzira maitiro, kunyanya paaluminium, magnesium, titanium uye alloys avo. Hurema hwakafumurwa mushure mekunhonga kweasina-ferrous alloy forgings anowanzo kucheneswa nemafaira, scrapers, grinders kana pneumatic maturusi. Kukanganisa kwesimbi yefogi kunocheneswa ne pickling, jecha blasting (pfuti), kuputika kwepfuti, roller, vibration nedzimwe nzira.

Acid kuchenesa

Kubviswa kwesimbi oxides nemakemikari reactions. Kune madiki uye epakati-akakura forgings anowanzo kutakurwa mudengu mumabhachi, mushure mekubviswa kwemafuta, pickling corrosion, rinsing, kuomesa uye mamwe maitiro. Iyo pickling nzira ine hunhu hwemhando yepamusoro yekugadzira, yakanaka yekuchenesa mhedzisiro, hapana deformation yefogi uye isina kurambidzwa chimiro. Pickling kemikari reaction process inozoburitsa magasi anokuvadza, saka, iyo pickling room inofanirwa kunge iine exhaust mudziyo. Kunonga zvakasiyana simbi forgings vanofanira kusarudza akasiyana asidhi uye kuumbwa reshiyo maererano simbi zvivakwa, uye kutora inoenderana pickling muitiro (tembiricha, nguva uye yekuchenesa nzira) hurongwa.

Kuputika kwejecha (pfuti) uye kupfura kuputika kwekuchenesa
Nemhepo yakamanikidzwa sesimba rejecha rinoputika (pfuti), ita jecha kana simbi pfuti ibudise kumhanya-mhanya (sandblasting kushanda kumanikidza kwe 0.2 ~ 0.3Mpa, kupfurwa kudongorera kushanda kumanikidza kwe0.5 ~ 0.6Mpa), jeti kuenda kunzvimbo yekugadzira bvisa oxide scale. Kuputika kwepfuti kunoitwa nekumhanya kukuru (2000 ~ 30001r/min) inotenderedza centrifugal simba remushonga, simbi inopfurwa kunzvimbo yekugadzira kugogodza sikero yeoxide. Guruva rejecha, kushanda kwakaderera kwekugadzira, mutengo wakakwira, unoshandiswa zvakanyanya kune zvakakosha zvehunyanzvi zvinodiwa uye zvakakosha zvekugadzira zvinhu (senge simbi isina simbi, titanium alloy), asi inofanirwa kutora inoshanda yekubvisa guruva matanho ehunyanzvi. Shot peening yakanyatso kuchena, kune zvakare zvakaipira zvekushomeka kwekugadzira uye mutengo wakakwira, asi mhando yekuchenesa yakakwira. Shot blasting inoshandiswa zvakanyanya pakugadzirwa kwayo kwepamusoro uye kushandiswa kwakaderera.
Shot peening uye kupfura kuputika kuchenesa, panguva imwe chete, kugogodza kubva pachiyero che oxide, ita kuti iyo yekugadzira nzvimbo ishande yakaoma, inobatsira kuvandudza kuneta kuramba kwezvikamu. Kune forgings mushure mekudzima kana kudzima uye kupisa kurapwa, basa rekuomesa mhedzisiro inonyanya kukosha kana uchishandisa yakakura saizi simbi kupfura, kuomarara kunogona kuwedzerwa ne30% ~ 40%, uye ukobvu hwekuomarara hunogona kusvika 0.3 ~ 0.5mm. Mukugadzira zvinoenderana nezvinhu uye tekinoroji zvinodiwa zve forgings kusarudza zvakasiyana zvinhu uye particle size yesimbi kupfura. Kushandiswa kwejecha kuputika (pfuti) uye nzira yekuputika kwepfuti yekuchenesa mafogi, kuputika kwepamusoro uye humwe hurema hunogona kuvharwa, zviri nyore kukonzera kupotsa kuonekwa. Naizvozvo, zvinodikanwa kushandisa magineti kutadza kuona kana fluorescence ongororo (ona yemuviri uye kemikari kuongororwa kwekuremara) kuti uongorore hurema hwepamusoro hwefogi.

kudonha
Iwo mafogi, mudhiramu rinotenderera, anodhumhana kana kukuyana kuti abvise oxide scale uye burr kubva workpiece. Iyi nzira yekuchenesa inoshandisa zviri nyore uye zviri nyore zvishandiso, asi ruzha rukuru. Inokodzera madiki uye epakati-saizi forgings ayo anogona kutakura kumwe kukanganisa uye zvisiri nyore kukanganisa. Drum yekuchenesa haina abrasive, chete wedzera katatu simbi kana simbi bhora dhayamita ye10 ~ 30mm yeasina-abrasive kuchenesa, kunyanya nekudhumhana kubvisa oxide scale. Imwe yacho ndeyekuwedzera jecha requartz, zvimedu zvemavhiri ekukuya uye mamwe mabrasives, sodium carbonate, mvura ine sipo uye zvimwe zvinowedzera, kunyanya nekukuya pakuchenesa.

Vibration kuchenesa
Mune forgings yakavhenganiswa nechimwe chikamu abrasives uye additives, akaiswa mumudziyo vibrating, kubudikidza vibration mugaba, kuti workpiece uye abrasive achikuya mumwe, pamusoro forgings oxide uye burr kure. Iyi nzira yekuchenesa yakakodzera kucheneswa uye kukwenenzverwa kwezvidiki uye zvepakati-saizi chaiyo forgings.
