Munzvimbo yekushandiswa kwemaindasitiri, kudiwa kwezvinhu zvinogara uye zvinopfekwa zvakakoshesesa, kunyanya muminda umo masimba abrasive uye mamiriro akaomarara akapararira. Chimwe chinhu chakadaro chakawana mukurumbira mumaindasitiri akasiyana-siyana isimbi inopisa-inoputira kupfeka-resistant ball steel. Iyi innovative alloy inomiririra kusimudzira kwakakosha muinjiniya yemidziyo, inopa kuomarara kwakasarudzika, kuomarara, uye kuramba abrasion, zvichiita kuti ive sarudzo yakanaka yezvishandiso uko hupenyu hurefu uye kuvimbika kwakakosha.
Kupisa-yakamoneredzwa kupfeka-inodzivirira bhora simbi imhando yakasarudzika yesimbi yakagadzirwa kuti ishingirire kuoma kwenzvimbo dzinokuvadza, dzakadai semigodhi, kuvaka, uye kugadzira maitiro anosanganisira kupwanya nekukuya. Maitiro ekugadzira anosanganisira kuisa pasi simbi kune yakanyanya tembiricha panguva yekupisa inopisa, inoteverwa neinodzorwa kutonhora, iyo inopa chaiyo mechanical uye metallurgical properties kuzvinhu. Iyi inyanzvi yekugadzira maitiro inoguma mune alloy yesimbi ine yakawedzera kuomarara uye kupfeka kuramba, ichiisa parutivi kubva kune akajairwa simbi.
Hunhu hwekutanga hunosiyanisa simbi inopisa-yakatenderedzwa kupfeka-inodzivirira bhora kuoma kwayo kunoshamisa, kunowanzo kuyerwa pachikero cheRockwell. Uku kuoma kwakasiyana kunowanikwa kuburikidza nekunyatsosarudzwa kwealloying zvinhu, kupisa kupisa, uye kunyatso kudzora maitiro ekugadzira. Iyo microstructure yesimbi yakarongedzwa kuti ibatanidze zvikamu zvakaoma, senge carbides, izvo zvinobatsira mukukwanisa kwayo kutsungirira kupfeka kweabrasive, kukanganisa, uye mitoro inorema.
Zvishandiso zve-hot-rolled wear-resistant bhora simbi zvakasiyana uye zvinotenderera mumaindasitiri akawanda. Mumabasa emigodhi, aya mabhora esimbi anoshandiswa mukupwanya nekukuya, uko ore inoderedzwa kuita zvidimbu zvakanatswa. Saizvozvo, maindasitiri anobatanidzwa mukugadzira simende, kugadzirwa kwemagetsi, uye kugadzirwa kwemakemikari anobatsirwa kubva mukupokana kwepamusoro kweaya mabhora esimbi mumakina akasiyana siyana nemidziyo.
Uyezve, kushandiswa kwekupisa-yakaputirwa kupfeka-inodzivirira bhora simbi kunobatsira kuwedzera kushanda zvakanaka uye kudhura-kubudirira mumagadzirirwo emaindasitiri nekuderedza nguva yekudzikira uye mari yekugadzirisa inoenderana nekupfeka kwemidziyo. Hupenyu hurefu hwemabhora esimbi aya hunoshandura hupenyu hwakawedzerwa hwesevhisi kumakina, pakupedzisira hunovandudza kugadzirwa kwese uye pundutso yekushanda kwemaindasitiri.
Mukupedzisa, hot-yakakungurutswa kupfeka-inodzivirira bhora simbi inomira seuchapupu hwekufambira mberi kwesainzi yemidziyo, ichipa mhinduro kumatambudziko anokonzerwa neabrasive nharaunda mumaindasitiri akasiyana siyana. Musanganiswa wayo wakasarudzika wekuoma, kuomarara, uye kupfeka kuramba kunoita kuti ive chinhu chakakosha mumakina nemidziyo uko kusimba kusingagone kutaurirana. Sezvo maindasitiri ari kuramba achishanduka, basa resimbi rinopisa-rakakungurutswa rinodzivirira bhora rinogona kuwedzera, richipa mhinduro dzekusingaperi kune zvinogara zvichikura zvinodiwa zvekushandisa zvazvino.
