Marollerndiwo matanho akakosha zvikuru mumaitiro ekuumba kutonhora-kukotamaSaka, zvinhu zvakasarudzwa zveroller chinhu chakakoshawo pakuongorora mhando yemuchina wekugadzira mupumburuKusarudzwa kwezvinhu zvakasiyana-siyana zvemaroller kunokonzera mutsauko mukuru pamhando yeprofile uye pamutengo wekugadzira. Mumusika wemuchina wekugadzira maroller wekuChina, zvinhu zvemaroller zvinowanzo kamurwa kuita mhando dzinotevera: 45 simbi, 45 simbi yakaiswa electroplated neCr, GCr15, Cr12, Cr12MOV, nezvimwewo.
Vagadziri vazhinji vanozochinjawo maroller kuita simbi yekukanda kuitira kuchengetedza mari. Vatengi vanofanirwa kunyatsosiyanisa paunotenga michina. Nekuda kwesimbi dzakasiyana dziri muzvinhu zvemakemikari C, Cr, MO, V, nezvimwewo zvezvinhu zvataurwa pamusoro apa, mashandiro ekuita uye mutengo zvakasiyana zvikuru, saka mashandisirwo ari kuitwa mukugadzira akasiyanawo. Kune ma coil akajairwa ane simba rekugadzira risingasviki 330Mpa uye ukobvu huri pasi pe1.5mm, senge masheets anoputirwa nemoto, masheets anoputirwa nemhepo inotonhora, PPGI, galvanized steel, 45 steel kana 45 steel chromed zvinogona kusangana nezvinodiwa. Kuti maroller asaite ngura uye kuwedzera hupenyu hwebasa remaroller, Linbay Machinery inoshandisa chrome plating process kune ese maroller esimbi makumi mana nemashanu (ukobvu hwe chrome plating i0.05mm), uye kuomarara mushure mekupisa kunogona kusvika 58-62HRC, iyo yakafanana nekuomarara kweCr12 neGCr15. Kunyangwe ichideredza mitengo, inowana mhando yakanaka panguva imwe chete. Kana uchida kugadzira ma coil ane simba guru ane simba rekugadzira rinodarika 350Mpa kana ma coil esimbi isina ngura, Linbay Machinery ichasarudza GCr15 kana Cr12 sezvinhu zvema roller, izvo zvinodhura zvakanyanya. Zvinhu zviviri izvi zvine simba rekudzivirira kupisa, kugadzikana kwekupisa uye simba rekumanikidza, uye kushanda zvakanaka kwazvo. Pakati pazvo, chikamu cheCr12 chakaenzana neAmerican Standard D3. Kuwedzera pakushandiswa sechinhu chekuputira, Cr12 inowanzo shandiswawo sechinobaya, chinopisa, uye chinopinza. Chinhu chemhando yepamusoro chema roller iCr12Mov kana Japanese standard SKD11 kana American standard D2, iyo inodhura zvikuru kana ichienzaniswa nedzimwe, ine simba rekudzivirira kupisa uye inogara kwenguva refu. Pamusoro pekushandiswa sechinhu chekuputira, Linbay Machinery inowanzo shandisa chinhu ichi chekucheka banga.
Pamusoro pezvose, unogona kusarudza zvinhu zveroller zvinoenderana nezvinodiwa paprofile yako uye bhajeti rekudyara. Linbay Machinery inogara ichikupa mhinduro yakanakisa kune zvaunoda, kuitira kuti ugone kutenga muchina wekugadzira roll unogutsa zvikuru.
