Lirolarake mohato oa bohlokoa ka ho fetisisa homokgoa o batang wa ho bopa. Ka hona, thepa e khethiloeng bakeng sa rolara e boetse ke ntlha ea bohlokoa ea ho ahlola boleng bamochini o etsang roll. Khetho ea lisebelisoa tse fapaneng tsa lirolara e tla baka phapang e kholo boleng ba profil le ka theko ea tlhahiso. 'Marakeng oa mochini oa mochini oa China, lisebelisoa tsa lirolara hangata li arotsoe ka mefuta e latelang: 45 tšepe, 45 tšepe electroplated le Cr, GCr15, Cr12, Cr12MOV, joalo-joalo.
Baetsi ba bangata le bona ba tla fetola lirolara hore li lahle tšepe e le ho boloka litšenyehelo. Bareki ba hloka ho khetholla ka hloko ha u reka mechini. Ka lebaka la likarolo tse fapaneng tsa tšepe tsa likarolo tsa lik'hemik'hale C, Cr, MO, V, joalo-joalo tsa mefuta e 'maloa ea lisebelisoa tse boletsoeng ka holimo, ts'ebetso ea ts'ebetso le theko li fapane haholo, kahoo kopo tlhahisong e boetse e fapane. Bakeng sa li-coil tse tloaelehileng tse nang le matla a ho hlahisa ka tlase ho 330Mpa le bophara ba botenya bo ka tlase ho 1.5mm, joalo ka maqephe a chesang a chesang, maqephe a batang, PPGI, tšepe ea galvanized, 45 steel kapa 45 steel chromed e ka finyella litlhoko. E le ho thibela li-roller hore li se ke tsa mafome le ho lelefatsa bophelo ba tšebeletso ea li-roller, Mechini ea Linbay e sebelisa mokhoa oa ho roala ka chrome ho li-roller tsohle tse 45 tsa tšepe (botenya ba chrome ke 0.05mm), 'me boima ba ka mor'a phekolo ea mocheso bo ka fihla ho 58-62HRC. e batla e tšoana le ho thatafala ha Cr12 le GCr15. Ha e ntse e fokotsa litšenyehelo, e fumana boleng bo botle ka nako e le 'ngoe. Haeba u batla ho hlahisa likhoele tse matla haholo tse nang le matla a ho kotuloa a fetang 350Mpa kapa litšepe tse sa hloekang, Linbay Machinery li tla khetha GCr15 kapa Cr12 joalo ka thepa ea lirolara, tse theko e phahameng haholo. Lisebelisoa tsena tse peli li na le khanyetso e phahameng ea ho apara, botsitso ba mocheso le matla a ho hatella, ts'ebetso e babatsehang ka kakaretso. Har'a tsona, karolo ea Cr12 e lekana le American Standard D3. Ntle le ho sebelisoa joalo ka thepa ea roll, Cr12 e boetse e sebelisoa hangata joalo ka setebele, ho shoa le ho kenya thepa. Thepa ea boleng bo holimo ea lirolara ke Cr12Mov kapa SKD11 e tloaelehileng ea Sejapane kapa D2 ea Amerika, e theko e phahameng haholo ha e bapisoa le tse ling, e na le khanyetso e phahameng ea ho roala ebile e na le nako e telele ea ts'ebeletso. Ntle le ho sebelisoa e le lisebelisoa tsa rolara, Mechini ea Linbay hangata e sebelisa thepa ena ho seha lehare.
Ka holim'a tsohle, o ka khetha thepa ea rolara ho latela litlhoko tsa profil ea hau le tekanyetso ea matsete. Linbay Machinery e tla lula e u fa tharollo e molemohali bakeng sa litlhoko tsa hau tse ikhethileng, e le hore u ka reka mochini o khotsofatsang haholo oa ho etsa moqolo.
