Zogudubuza mpherozimagwira ntchito yofunika kwambiri pamakampani opanga zinthu, kusandutsa zida kukhala mitundu yosiyanasiyana yazitsulo. Pakati pa magwiridwe antchito a mphero ndimipukutu, omwe ali ndi udindo wopanga, kuchepetsa makulidwe ndi kupereka zinthu zofunika kuzitsulo. Mu blog iyi, tiwona kufunikira kwa ma rolls a mphero ndikuwunika momwe amathandizira pakukula kwa ntchito yopanga.

Pankhani yogubuduza mphero, amipukutukutenga pakati siteji. Magawo a cylindrical awa amapangidwa kuti athe kupirira kupsinjika kwakukulu, kutentha ndi mphamvu zomwe zimapangidwa pakugubuduza. Ntchito yawo yayikulu ndikugwiritsa ntchito mphamvu pa workpiece, kaya ndi chitsulo, aluminiyamu kapena chitsulo china chilichonse, potero amachipanga kukhala mawonekedwe omwe akufuna. Mipukutu imathandizira kusintha kuchokera ku ma ingots kapena masilabu kupita ku mawonekedwe osavuta kuwongolera monga mapepala, mbale kapena waya.

Wodzigudubuza, mawu ena amene nthaŵi zambiri amagwiritsidwa ntchito mofanana ndi mpukutu, ndi mbali yofunika kwambiri ya mphero. Iwo ali ndi udindo wochepetsera makulidwe a zitsulo pamene akudutsa mu mphero yogubuduza. Odzigudubuza amagwiritsira ntchito kukakamiza kwachitsulo, pang'onopang'ono kuchepetsa makulidwe ake ndikusunga m'lifupi mwake. Izi zimatsimikizira kugwirizana kwa chinthu chomaliza, kaya ndi chitsulo chachitsulo chomwe chimagwiritsidwa ntchito m'makampani oyendetsa galimoto kapena ma coil pamagetsi.

Zosiyanasiyana zogwiritsa ntchito mumafakitale achitsuloatsegula njira yopangira mipukutu yosiyanasiyana yoyenera njira zosiyanasiyana. Malingana ndi zofunikira zenizeni za mphero yogubuduza, zakuthupi, kukula, chithandizo cha kutentha ndi mapeto a pamwamba pa mipukutuyo zingasiyane. Mitundu yofala kwambiri imaphatikizapomipukutu ya ntchito, zosunga zobwezeretserandi ma rolls apakatikati. Mipukutu yogwirira ntchito imagwirizana mwachindunji ndi zitsulo, pamene mipukutu yobwereranso imapereka chithandizo ndikuletsa kuwonongeka kwa mawonekedwe chifukwa cha kupanikizika kwakukulu. Thewodzigudubuza wapakatikatikumathandiza kulekanitsa odzigudubuza ntchito ndi kusintha mavuto a zinthu.

Kusankha ma rolls apamwamba kwambiri ndikofunikira kuti musunge magwiridwe antchito ndi kutulutsa kwa mphero yanu. Mipukutu yokhala ndi zinthu zabwino kwambiri, monga kuvala kwambiri, kutentha ndi kukana kutopa, imatha kupirira mikhalidwe yovuta kwambiri tsiku ndi tsiku, kuchepetsa nthawi yopuma komanso kukulitsa moyo wautumiki. Kuphatikiza apo, miyeso yolondola, kumaliza bwino kwa pamwamba ndi kuyika bwino kwa mpukutu kumathandizira kukonza zinthu, kuchepetsa kuwononga zinthu ndikuwongolera magwiridwe antchito.

Kwa zaka zambiri, kupita patsogolo kwa sayansi ndi uinjiniya wazitsulo kwasintha kwambiri kamangidwe ndi kupanga ma rolling mill rolls. Ma alloys opangidwa mwaluso, monga chitsulo chothamanga kwambiri, chitsulo chachitsulo ndi magiredi osiyanasiyana a carbide, amawongolera magwiridwe antchito komanso kulimba kwa mipukutu. Kuphatikiza apo, kupita patsogolo kwaukadaulo wopanga mipukutu monga kuponyera kwa centrifugal ndi njira zochizira kutentha kwathandizira kwambiri kuwongolera moyo ndi magwiridwe antchito a rolling mill rolls.

Mwachidule, ma rolling mill rolls amakhala ngati ngwazi zosadziwika, zomwe zimathandizira kusintha kwazitsulo kukhala zinthu zamtengo wapatali zomwe zimayendetsa mafakitale ambiri. Kuchokera pakupanga ndi kuchepetsa makulidwe mpaka kupereka zomwe mukufuna ku chitsulo, mipukutu ndi gawo lofunikira pakugudubuza. Pomvetsetsa kufunikira kwa ma rolls ndikutengera kupita patsogolo kwaukadaulo, opanga amatha kukhathamiritsa ntchito zawo zogubuduza, kukhala ndi zokolola zambiri, ndikupereka zinthu zabwino kwambiri kuti zikwaniritse zomwe makampani amasiku ano akukulira.
