Ukulungiswa kwendawo yisona sinyathelo esibaluleke kakhulu ngaphambi kokufaka unswakelo kunoma yisiphi isakhiwo sensimbi esizochitha amashumi eminyaka emanzini olwandle. Amapulangwe omkhumbi nezingxenye zokwakha zifika egcekeni zimbozwe i-mill scale, ukugqwala, namafutha okugoqwa angonakalisa ngokuphelele ukunamathela konswakelo uma kungelashwa. Ngisho nongqimba oluncane lokungcola ngaphansi kwefilimu kapende ludala i-electrochemical cell esheshisa ukugqwala futhi luholele ekwehlulekeni konswakelo ngaphambi kwesikhathi okubizayo. Izinhlangano zokuhlukanisa imikhumbi nabahlinzeki bonswakelo bafuna ubufakazi obucacile bokuhlanzeka nokulinganiswa kweprofayili ngaphambi kokufaka i-primer, futhi noma ukuphambuka kusho ukuphinda kwenziwe nokubambezeleka edokini. I-cast steel shot yokwakha imikhumbi iyona thuluzi eliqondile elisetshenziswa amagceke ukufeza lezi zimfuneko eziqinile ngendlela ephindaphindekayo nongaphandle kokulahlekelwa. Ukubuka okuphelele kwamazinga atholakalayo we-media kungatholakala ku-IKHASI LASEKHAYA ikhasi.

Ukuhlanza nge-steel shot (abrasive blasting) kususa ukugqwala (rust), imbuzo yensimbi (mill scale), kanye nokugqokwa okudala, kuyilapho kanyekanye kufaka iphethini elawulwayo (anchor pattern) ebusweni bensimbi. Umthelela obukhali, ongaguquki we-shot ususa ukungcola futhi uqinisa insimbi ukuze ibe nobushaqa obufanayo (uniform roughness) okudingwa izinhlelo zokugqoka (coating systems). Ngenxa yokuthi i-shot isetshenziswa kabusha izikhathi eziningi, le nqubo ikhiqiza imfucuza encane kakhulu kune-abrasives ezilahlwayo, okwehlisa izindleko zokulahla imfucuza futhi kugcine igceke lihlanzekile. Abasebenzi bangalungisa umfutho (pressure), i-engeli, nosayizi we-shot ukuze balungise umphumela (profile) ngokwe-coating ecacisiwe, okubanika ukulawula okugcwele ngomphumela. Le nhlanganisela yamandla okuhlanza, ukuphindaphindeka, kanye nomnotho yilokho okwenza izinkampani eziningi zanamuhla zokwakha imikhumbi zithembele ezinhlelweni ze-steel shot blasting njengendlela yazo eyinhloko yokukhiqiza. Ekugcineni, ukukhethwa kwe-abrasive kunquma ngokuqondile kokubili ikhwalithi ye-coating kanye nezindleko eziphelele zamasikweletha ngamunye acutshungulwayo.

Ukusebenza kokuhlanzwa ngamandla kungavamile ukuba umphumela wenombolo eyodwa, kodwa izici ezimbalwa zomzimba zinquma iningi lomphumela. Ubulukhuni, usayizi wezinhlayiya, ukuma, kanye nesakhiwo esincane kuthinta ngayinye ukuthi i-shot ihlanza ngokushesha kangakanani nokuthi ihlala isikhathi esingakanani kumjikelezo wokubuyisela. Ukuqonda lezi zici kusiza abaqhubi ukuthi bacacise i-media efanele yamapuleti endekhi, ingaphandle le-hull, kanye nomsebenzi wesakhiwo ngaphandle kokukhokha ngokweqile ngekhono abangalidingi. Izigaba ezingezansi zichaza isici ngasinye ngamagama asebenzayo umphathi wokuqhuma angawasebenzisa ngqo emsebenzini. Lolu lwazi futhi lwenza kube lula ukuhlola izitifiketi zomthengisi nokwenqaba ukulethwa okungahambisani nezimfuneko ngaphambi kokuba kufinyelele emshinini wokuqhuma.

Ukuqina kukalwa ngesikali se-Rockwell C futhi kuwumthetho wokuqala umkhumbi awuhlola lapho u-oda izinto ezintsha. I-shot eqinile idlulisa amandla amaningi e-kinetic lapho ishaya futhi ikhipha i-rust ne-scale ngokushesha, okufinyeza isikhathi sokuqhuma futhi kukhulise umkhiqizo. Nokho, i-shot eqine kakhulu ingaphinde ilimaze i-substrate uma ihlukana, futhi izinto eziphukayo ngokweqile zidala ukugqoka okweqile kuma-impeller omshini wokuqhuma nezingxenye zangaphakathi. Ezinkundleni zomzimba wezikebhe kanye nezinto eziningi ze-carbon steel, ububanzi bokuqina obungu-40 kuya ku-51 HRC bunikeza ibhalansi engcono kakhulu yokushesha nokuqina. I-shot ethambile engaphansi kuka-40 HRC ivamise ukuphahlazeka ngokushesha futhi ilahlekelwe ukusebenza kahle kokuhlanzwa, kuyilapho amazinga angaphezu kuka-51 HRC kufanele agcinelwe umsebenzi okhethekile we-peening kunokuhlanzwa okujwayelekile. Umkhiqizi oqinisekisiwe uyohlale eshicilela ububanzi bokuqina esitifiketini se-lot ukuze ukwazi ukuqinisekisa ukuthobela imithetho lapho uthola izinto.

Usayizi we-shot ulawulwa yi-SAE J444, ehlukanisa i-steel shot ngokuvuleka kwe-sieve okukalwa ngezinkulungwane ze-intshi. I-shot enkulu ikhiqiza i-anchor pattern ejulile futhi isusa ukungcola okunzima ngokushesha, kodwa ingase yeqe i-profile ecacisiwe umkhiqizi we-coating futhi ilahle i-media. I-shot encane idala i-profile eqinile, ephansi efanele i-primers ezincanyana nezidingo zokuqedela okubushelelezi ezingxenyeni zangaphakathi. Ukukhetha ingxube efanele kuvame ukubaluleka kakhulu kunokukhetha usayizi owodwa, ngoba ingxube ehlanganiswe kahle igcwalisa indawo ngempumelelo futhi igweme izikhala ekumbozeni.
