I-Solid Forged Steel Work Roll, I-Integrated Heavy-Duty Rolling Mill Roll ye-Seamless Tube kunye ne-Plate Rolling

Iiroli zentsimbi eziqinisiweyo zizinto eziqengqelekayo ezenziwe ngentsimbi enye, ngaphandle kwendandatho yangaphandle edibeneyo okanye enemikhono. Umzimba wonke weeroli kunye neziphelo zeshaft zenziwe ngokubumba, kulandele unyango lobushushu, ukujika okurhabaxa, ukujika okugqityiweyo kunye nokusila ngokuchanekileyo.

Uluhlu olubanzi lwee-alloy steel grades lunokukhethwa ngokweemeko zokusebenza eziqengqelekayo, kuquka i-Cr-series alloy steel, i-high-chromium forged steel, i-semi-high-speed steel kunye ne-high-speed steel. Ngokusebenzisa i-quenching kunye ne-tempering ephuculweyo kunye nonyango lokuqina komphezulu, le miqulu ifezekisa ukusebenza okulinganayo: amandla aphezulu okuxinana, ukuqina okuhle, ukumelana okunamandla nokudinwa kobushushu kunye nokumelana okugqwesileyo kokuguguleka. Ngokungafaniyo nemiqulu edibeneyo, akukho nxibelelwano lokubopha phakathi kwezinto ezahlukeneyo, okususa umngcipheko wokukhululeka kwendandatho okanye ukwahlukana phantsi kwemithwalo enzima yokuqengqeleka.

Iiroli zentsimbi eziqinileyo ezibunjiweyo zisetyenziswa kakhulu kwiinkqubo zokuqengqeleka ezithwala umthwalo onzima. Iimeko eziqhelekileyo zokusetyenziswa ziquka ii-seamless steel pipe mills, ii-plate kunye nee-medium plate rolling mills, ii-heavy bar kunye nee-large section steel rolling stands. Zikwasetyenziswa njengee-backup rolls kunye nee-work rolls kwimigca ebandayo yokuqengqeleka.

Iingenelo zabo ezibalaseleyo zikwimeko entle kakhulu yesakhiwo kunye nokumelana nokuchasana okuthembekileyo kwempembelelo. Isakhiwo sokwakha esidibeneyo sinokumelana noxinzelelo olunzima lokuqengqeleka kunye nemithwalo yempembelelo ngamanye amaxesha. Unyango olufanelekileyo lobushushu luvumela umphezulu weroli ukuba ugcine ubulukhuni ngelixa ugcina umongo weroli uqinile, umelana ngempumelelo nokwanda kwemingxunya yobushushu kunye nokuqhekeka komphezulu ngexesha lokuqengqeleka okushushu okuqhubekayo.

Ngexesha lemveliso, kwenziwa uhlolo olungqongqo olungonakalisiyo olufana novavanyo lwe-ultrasonic ukuze kufunyanwe iziphene zokubumba kwangaphakathi, izinto ezifakiweyo kunye nee-voids. Ukusila ngokuchanekileyo kuqinisekisa ukugqitywa komphezulu okugqwesileyo kunye nokunyamezelana okuqinileyo, okuqinisekisa ubungakanani obuzinzileyo kunye nomgangatho womphezulu weemveliso zentsimbi ezigoqiweyo.

Nangona kunjalo, imiqulu yentsimbi eqinileyo eyenziwe ngobumba inemida ekugugeni xa ithelekiswa nemiqulu ye-tungsten carbide composite. Phantsi kweemeko zokuqengqeleka ezikhawulezayo nezinde, umngxuma wokuqengqeleka uyaguga ngokukhawuleza kwaye ufuna ukugaywa rhoqo. Ukukhetha inqanaba kunye nesicwangciso sonyango lobushushu kufuneka senziwe ngokwezifiso ngokusekelwe kumandla okuqengqeleka, ubushushu bokuqengqeleka, izinto zokusebenza kunye nesigqi semveliso.

Ngamafutshane, imiqulu yentsimbi eqinileyo eqinisiweyo lukhetho oluvuthiweyo noluthembekileyo kwiifektri eziqengqelekayo ezinzima. Ulwakhiwo lwazo oluqiniweyo oluyinxenye enye lunika uzinzo olubalaseleyo lwesakhiwo kunye nokumelana nempembelelo, nto leyo eyenza ukuba zibe zizinto ezisetyenziswayo ezibalulekileyo kwipleyiti, intsimbi enkulu kunye nemveliso yokuqengqeleka kweetyhubhu ezingenamthungo.
