Ma Rollerndi sitepe yofunika kwambiri munjira yopangira kuziziraChifukwa chake, zinthu zomwe zasankhidwa pa chopukutiracho ndi chinthu chofunikira kwambiri pakuweruza mtundu wamakina opangira mpukutuKusankha zipangizo zosiyanasiyana za ma rollers kumabweretsa kusiyana kwakukulu pa mtundu wa mbiri komanso mtengo wopangira. Mu msika wa makina opangira ma roll ku China, zipangizo za ma rollers nthawi zambiri zimagawidwa m'mitundu iyi: 45 chitsulo, 45 chitsulo chopangidwa ndi electroplated ndi Cr, GCr15, Cr12, Cr12MOV, ndi zina zotero.
Opanga ambiri amasinthanso ma roller kuti agwiritse ntchito chitsulo kuti asunge ndalama. Ogula ayenera kusiyanitsa mosamala mukagula makina. Chifukwa cha zinthu zosiyanasiyana zachitsulo zomwe zili mu C, Cr, MO, V, ndi zina zotero, za mitundu ingapo ya zipangizo zomwe zatchulidwa pamwambapa, momwe ntchito ndi mtengo wake zimagwirira ntchito zimasiyana kwambiri, kotero momwe zimagwiritsidwira ntchito popanga zinthu zimasiyananso. Pa ma coil wamba omwe ali ndi mphamvu yotsika kuposa 330Mpa komanso makulidwe osakwana 1.5mm, monga mapepala otenthedwa, mapepala ozizira, PPGI, galvanized steel, 45 steel kapena 45 steel chromed amatha kukwaniritsa zofunikira. Pofuna kupewa ma roller kuti asachite dzimbiri ndikuwonjezera moyo wa ma roller, Linbay Machinery imagwiritsa ntchito njira yopangira ma chrome pa ma roller onse 45 achitsulo (makulidwe a chrome plating ndi 0.05mm), ndipo kuuma pambuyo pa chithandizo cha kutentha kumatha kufika 58-62HRC, komwe kuli kofanana ndi kuuma kwa Cr12 ndi GCr15. Ngakhale kuchepetsa ndalama, kumakhala kwabwino nthawi imodzi. Ngati mukufuna kupanga ma coil amphamvu kwambiri okhala ndi mphamvu yotulutsa yoposa 350Mpa kapena ma coil achitsulo chosapanga dzimbiri, Linbay Machinery idzasankha GCr15 kapena Cr12 ngati zinthu zopangira ma rollers, zomwe ndi zodula kwambiri. Zipangizo ziwirizi zimakhala ndi kukana kwambiri kutopa, kukhazikika kwa kutentha komanso mphamvu yopondereza, komanso magwiridwe antchito abwino kwambiri. Pakati pawo, gawo la Cr12 ndi lofanana ndi American Standard D3. Kuphatikiza pa kugwiritsidwa ntchito ngati zinthu zozungulira, Cr12 imagwiritsidwanso ntchito kwambiri ngati nkhonya, die, ndi insert. Zipangizo zapamwamba kwambiri za ma rollers ndi Cr12Mov kapena Japanese standard SKD11 kapena American standard D2, zomwe ndi zodula kwambiri poyerekeza ndi zina, zimakhala ndi kukana kwambiri kutopa ndipo zimakhala ndi moyo wautali kwambiri. Kuphatikiza pa kugwiritsidwa ntchito ngati zinthu zozungulira, Linbay Machinery nthawi zambiri imagwiritsa ntchito izi podula tsamba.
Koposa zonse, mutha kusankha zinthu za roller malinga ndi zomwe mukufuna komanso bajeti yanu. Linbay Machinery nthawi zonse imakupatsani yankho labwino kwambiri pazosowa zanu, kuti mugule makina opangira ma roll oyenera kwambiri.
