Pakati pa miyezo ya mapaipi achitsulo chosapanga dzimbiri, kuuma kwa Brinell ndiko komwe kumagwiritsidwa ntchito kwambiri. M'mimba mwake nthawi zambiri amagwiritsidwa ntchito kuwonetsa kuuma kwa zinthuzo, zomwe zimakhala zosavuta komanso zosavuta. Koma sizoyenera mapaipi achitsulo opangidwa ndi chitsulo cholimba kapena chopyapyala.
Mayeso a Rockwell olimba pogwiritsa ntchito chitoliro chachitsulo chosapanga dzimbiri ndi ofanana ndi mayeso a Brinell olimba, omwe ndi njira yoyesera yolowera mkati. Kusiyana kwake ndikuti amayesa kuzama kwa kulowa mkati. Mayeso a Rockwell olimba pakadali pano ndi njira yomwe imagwiritsidwa ntchito kwambiri, pakati pawo HRC imagwiritsidwa ntchito mu miyezo ya chitoliro chachitsulo yachiwiri pambuyo pa Brinell hardness HB. Kulimba kwa Rockwell kungagwiritsidwe ntchito poyesa zipangizo zachitsulo kuyambira zofewa kwambiri mpaka zolimba kwambiri. Zimakwaniritsa zofooka za njira ya Brinell. Ndi yosavuta kuposa njira ya Brinell ndipo kuchuluka kwa kuuma kumatha kuwerengedwa mwachindunji kuchokera pa dial ya makina olimba. Komabe, chifukwa cha kulowa mkati kochepa, kuchuluka kwa kuuma sikolondola ngati njira ya Brinell.
Kuyesa kuuma kwa Vickers pogwiritsa ntchito chitoliro chachitsulo chosapanga dzimbiri ndi njira yoyesera yolowera mkati yomwe ingagwiritsidwe ntchito kudziwa kuuma kwa zinthu zoonda kwambiri zachitsulo ndi zigawo za pamwamba. Ili ndi ubwino waukulu wa njira za Brinell ndi Rockwell ndipo imagonjetsa zofooka zawo zoyambira, koma si zophweka ngati njira ya Rockwell. Njira ya Vickers siigwiritsidwa ntchito kawirikawiri mu miyezo ya chitoliro chachitsulo.
1. Mapepala apulasitiki
Ponyamula mapaipi achitsulo chosapanga dzimbiri, mapepala apulasitiki nthawi zambiri amagwiritsidwa ntchito popakira mapaipi. Njira yopakira iyi ndi yothandiza kuteteza pamwamba pa chitoliro chachitsulo chosapanga dzimbiri kuti chisawonongeke, kukanda ndi kuipitsidwa, komanso imagwira ntchito yoteteza chinyezi, fumbi komanso yoteteza dzimbiri.
2. Kulongedza tepi
Kuyika ma tepi ndi njira yotsika mtengo, yosavuta komanso yosavuta yoyika mapaipi achitsulo chosapanga dzimbiri, nthawi zambiri pogwiritsa ntchito tepi yoyera kapena yoyera. Kugwiritsa ntchito ma tepi sikungoteteza pamwamba pa payipi yokha, komanso kulimbitsa mphamvu ya payipi ndikuchepetsa kuthekera kosuntha kapena kupotoza payipi panthawi yoyendera.
3. Mapaleti amatabwa
Ponyamula ndi kusunga mapaipi akuluakulu achitsulo chosapanga dzimbiri, kulongedza mapaipi amatabwa ndi njira yothandiza kwambiri. Mapaipi achitsulo chosapanga dzimbiri amamangiriridwa pa mapaipi ndi zingwe zachitsulo, zomwe zingapereke chitetezo chabwino kwambiri ndikuletsa mapaipi kuti asagundane, kupindika, kusokonekera, ndi zina zotero panthawi yonyamula.
4. Katoni yolongedza
Pa mapaipi ena ang'onoang'ono osapanga dzimbiri, kulongedza makatoni ndi njira yodziwika bwino. Ubwino wa kulongedza makatoni ndikuti ndi opepuka komanso osavuta kunyamula. Kuwonjezera pa kuteteza pamwamba pa chitoliro, ingakhalenso yabwino kusungira ndi kuyang'anira.
5. Kuyika chidebe
Pa kutumiza mapaipi akuluakulu osapanga dzimbiri, kulongedza zidebe ndi njira yodziwika bwino. Kulongedza zidebe kumatha kuonetsetsa kuti mapaipi akunyamulidwa bwino komanso popanda ngozi panyanja, komanso kupewa kupatuka, kugundana, ndi zina zotero panthawi yonyamula.

Kasitomala Wathu
1. Mitengo yanu ndi yotani?
Mitengo yathu imasintha malinga ndi kupezeka kwa zinthu ndi zinthu zina pamsika. Tidzakutumizirani mndandanda wamitengo wosinthidwa mukamaliza kulankhulana ndi kampani yanu.
Titumizireni uthenga kuti mudziwe zambiri.
2. Kodi muli ndi oda yocheperako?
Inde, tikufuna kuti maoda onse apadziko lonse lapansi azikhala ndi oda yocheperako nthawi zonse. Ngati mukufuna kugulitsanso koma pang'ono kwambiri, tikukulimbikitsani kuti muyang'ane tsamba lathu lawebusayiti.
3. Kodi mungapereke zikalata zoyenera?
Inde, titha kupereka zikalata zambiri kuphatikizapo Zikalata Zowunikira / Kutsatira; Inshuwalansi; Chiyambi, ndi zikalata zina zotumizira kunja komwe kukufunika.
4. Kodi nthawi yoyambira ntchito ndi yotani?
Pa zitsanzo, nthawi yoperekera chithandizo ndi pafupifupi masiku 7. Pakupanga zinthu zambiri, nthawi yoperekera chithandizo ndi masiku 5-20 mutalandira ndalama zolipirira. Nthawi yoperekera chithandizo imayamba kugwira ntchito pamene
(1) talandira ndalama zomwe mudapereka, ndipo (2) talandira chilolezo chanu chomaliza cha zinthu zanu. Ngati nthawi yathu yopezera zinthu sikugwirizana ndi nthawi yanu yomaliza, chonde kambiranani zomwe mukufuna pogulitsa. Nthawi zonse tidzayesetsa kukwaniritsa zosowa zanu. Nthawi zambiri timatha kutero.
5. Ndi mitundu yanji ya njira zolipirira zomwe mumavomereza?
30% pasadakhale pofika pa T/T, 70% idzakhala yoyambira isanatumizidwe pa FOB; 30% pasadakhale pofika pa T/T, 70% motsutsana ndi kopi ya BL basic pa CIF.
