Zvigayokuita basa rakakosha muindasitiri yekugadzira, kushandura mbichana kuita mhando dzakasiyana dzezvigadzirwa zvesimbi. Pakati pekushanda kwechigayo ndichorolls, iyo inokonzera kuumbwa, kuderedza ukobvu uye kugovera zvinhu zvinodiwa kune simbi. Mune ino blog, isu tichaongorora kukosha kwekutenderedza mill rolls uye tiongorore kuti anobatsira sei mukusimudzira maitiro ekugadzira.

Kana zvasvika pazvigayo, therollskutora nzvimbo yepakati. Aya ma cylindrical mativi akagadzirwa kuti amire kumanikidza kwakanyanya, kupisa uye simba rinogadzirwa panguva yekukunguruka. Basa ravo guru nderekushandisa simba pane workpiece, ingave simbi, aluminium kana chero imwe simbi, nokudaro vachiiumba muchimiro chaunoda. Rolls inofambisa shanduko kubva kune ingots kana slabs kune mamwe anogoneka maumbirwo semashiti, mahwendefa kana kunyange waya.

Roller, rimwe shoko rinowanzoshandiswa zvakafanana nerokuti roll, chikamu chinokosha cheguyo. Ndivo vane basa rekudzikisa ukobvu hwesimbi sezvo ichipfuura nepaguyo. Iwo ma rollers anoshandisa kumanikidza kune simbi, zvishoma nezvishoma kuderedza ukobvu hwayo uchichengetedza hupamhi hunoenderana. Iyi nzira inovimbisa kuenderana kwechigadzirwa chekupedzisira, ingave iri simbi simbi inoshandiswa muindasitiri yemotokari kana makoiri mumagetsi ekushandisa.

Izvo zvakasiyana-siyana zvekushandisa muindasitiri yesimbivakagadzira nzira yekugadzirwa kwemhando dzakasiyana-siyana dzakakodzera maitiro akasiyana-siyana. Zvichienderana nezvinodiwa chaizvo zvechigayo chinotenderedza, zvinhu, saizi, kurapwa kwekupisa uye kupera kwepamusoro kwemapumburu zvinogona kusiyana. Mhando dzakawanda dzinosanganisirawork rolls, backup rollsuye mipumburu yepakati. Mipumburu yebasa iri kutarisana zvakananga nesimbi, nepo ma-back-up rolls anopa rubatsiro uye kudzivirira kukanganisa kwechimiro kunokonzerwa nepamusoro-kudzvinyirira mamiriro. Theintermediate rollerinobatsira kuparadzanisa ma rollers ebasa uye kugadzirisa kushushikana kwezvinhu.

Kusarudza epamusoro-mhando rolls kwakakosha kuchengetedza kushanda uye kugadzirwa kwechigayo chako. Rolls ine zvinhu zvakanakisa zvezvinhu, senge kupfeka kwakanyanya, kupisa uye kuneta kuramba, inogona kumirisana neyakaomarara mamiriro ekutenderera zuva nezuva, ichideredza nguva yekudzikira uye kuwedzera hupenyu hwesevhisi. Pamusoro pezvo, zviyero zvakaringana, kupedzisa kwepamusoro uye kurongeka kwakaringana kunobatsira kuvandudza kunaka kwechigadzirwa, kuderedza kutambisa zvinhu uye kunatsiridza kunyatsoshanda.

Kwemakore, kufambira mberi mune metallurgical sainzi neinjiniya kwakashandura dhizaini uye kugadzirwa kwema rolling mill rolls. Innovative alloys, yakadai seyepamusoro-speed simbi, simbi yekushandisa uye akasiyana-siyana magiredhi e carbide, anovandudza mashandiro uye kusimba kwemapumburu. Pamusoro pezvo, kufambira mberi mukugadzira tekinoroji senge centrifugal casting uye maitiro ekurapa kupisa kwaita basa rakakosha mukuvandudza hupenyu nekuita kwe rolling mill rolls.

Muchidimbu, rolling mill rolls inoshanda semagamba asina kufambwa, achifambisa shanduko yesimbi kuita zvigadzirwa zvakakosha zvinosimbisa maindasitiri mazhinji. Kubva pakuumba nekudzikisira ukobvu kusvika pakupa zvinhu zvinodiwa kune simbi, mipumburu chikamu chakakosha chekukunguruka. Nekunzwisisa kukosha kwemaroll uye kutora kufambira mberi kwetekinoroji, vagadziri vanogona kukwidziridza mashandiro avo echigayo, kuwana chigadzirwa chepamusoro, uye kuendesa zvigadzirwa zvemhando yepamusoro kuti zvizadzise zvinodiwa neindasitiri yanhasi.
