Ntchito Zokonza ndi Kusintha Mapepala Ovekedwa ndi Overlay Wear

Mu mafakitale amakono, mbale zovekera za CCO (mbale yosagwira ntchito yoteteza chromium carbide() imagwiritsidwa ntchito kwambiri m'malo omwe zinthu zimawonongeka kwambiri monga migodi, zipangizo zomangira, chitsulo, ndi magetsi chifukwa cha kukana kwake kuvala bwino komanso kusinthasintha kosiyanasiyana kwa zinthu zomwe zimagwiritsidwa ntchito. Imapangidwa ndi alloy ya chromium yokhala ndi kaboni wambiri yomwe imalumikizidwa pamwamba pa chitsulo chopanda kaboni wambiri, ndikupanga kapangidwe kake kosagwirizana ndi kuvala kwa bimetallic komwe kumakhala kolimba komanso kolimba, komwe kumatha kukulitsa moyo wa zida ndikuchepetsa ndalama zosamalira. Nkhaniyi ifotokoza kapangidwe kake, mawonekedwe ake, ndi ntchito zosinthira zomwe zakonzedwa kale za mbale yovala ya CCO kuti zithandize ogwiritsa ntchito kumvetsetsa bwino ndikugwiritsa ntchito izi.

Kapangidwe ka mbale yosavala yophimba pamwamba

Chopangira cha chromium chokhala ndi mpweya wambiri ndiye chinthu chachikulu chaMbale yovala ya CCO. Chigawo chake chachikulu chingapange kuchuluka kwa Cr7C3 hard carbide pansi pa kutentha kwambiri komanso kupanikizika kwambiri, ndikupanga kapangidwe ka eutectic + M7C3. Kapangidwe kameneka kamatsimikizira kukana kwake kuvala bwino, komwe kumakhalabe kokhazikika ngakhale m'malo ovuta kuvala. Kuti zinthu ziwongolere magwiridwe antchito onse, zinthu zazing'ono monga molybdenum, tungsten, vanadium, boron, ndi niobium zitha kuwonjezeredwa kuzinthuzo kuti ziwonjezere kuuma kwa kutentha kwambiri, kukana kugunda, komanso kukana dzimbiri.

Ma carbide a M7C3 amakonzedwa mozungulira pansi pa kapangidwe kake kakang'ono. Kapangidwe kameneka kangathebe kugwira ntchito bwino ngakhale kutentha kwambiri kapena kukangana kwakukulu, kopitilira chitsulo wamba.

Kuchita bwino kwa mbale yosavala pamwamba

Kukana kugwedezeka ndi chimodzi mwazofunikira kwambiri poyesa ubwino wa mbale zosatha. Chingwe cholumikizira chachitsulo cha mbale yosatha ya CCO chimapangitsa kuti chivundikirocho chikhale chomangiriridwa mwamphamvu ku substrate ya mbale yachitsulo, kuti chisakhale chosavuta kugwa, ndipo chimakhalabe chokhazikika komanso chodalirika ngakhale chikakhudzidwa kwambiri kapena chikalemera kwambiri.

Ma CCO plates amatha kugawa magawo molondola pogwiritsa ntchito laser, plasma, ndipo amathanso kukonzedwa m'njira zosiyanasiyana, monga kupindika kozizira, kuboola, kuwotcherera, ndi zina zotero, popanda kufooketsa kwambiri kukana kwawo kutopa. Mwachitsanzo, 5+5 overlay clodding plate (5mm substrate + 5mm cladding layer) ndi mtundu wamba wa structural, womwe sumangokhala ndi mphamvu ya structural komanso umaganizira za kusawononga ndalama komanso kusinthasintha kwa processing.

Utumiki wokonza mbale wosawonongeka ndi overlay

Ngakhale akupereka zinthu zoteteza ku kuwonongeka kwa CCO, Wodon iperekanso ntchito zonse zokonza. Ponena za kudula, zida za plasma kapena laser zimagwiritsidwa ntchito podula mwanzeru kwambiri, zomwe sizimangogwira ntchito bwino komanso zili ndi malo ochepa omwe amakhudzidwa ndi kutentha, komanso zimakhala ndi mtundu wabwino kwambiri wa chinthu chomalizidwa.

Mwachitsanzo, pankhani yopindika ndi kupanga, mbale zachitsulo zosakanikirana za bimetallic zosatha kuzizira zimatha kukonzedwa mozizira kukhala zigawo zopindika kapena zozungulira kuti zikwaniritse zofunikira pakugwiritsa ntchito zida zovuta. Ntchito zobowola zimaphatikizapo kukonza mabowo owongoka ndi mabowo ozungulira, zomwe zimakhala zosavuta kulumikiza bolt kapena kuyika welding pambuyo pake. Kuphatikiza apo, mtundu uwu wa mbale wosatha kutha uli ndi kutha kusweka bwino ndipo ungagwiritsidwe ntchito kupanga zigawo zosatha kutha monga mabaketi ofukula, ma liners, ndi ma bushing a conveyor system.

Utumiki wosinthidwa

Poganizira kusiyana kwa zosowa za mafakitale osiyanasiyana ndi zida zogwiritsira ntchito zipangizo zosatha, Wodon imaperekanso njira zosinthira ma plate osatha. Kukhuthala kwa plate, kukula kwa plate, ndi zina zitha kusinthidwa malinga ndi zofunikira za ogwiritsa ntchito kuti zitsimikizire kuti chinthucho chikugwirizana bwino ndi momwe chikugwiritsidwira ntchito. Mwachitsanzo, pogwiritsira ntchito payipi yonyamula katundu wanga, zigawo zokhuthala za plaipe ndi mbale zophatikizika zosatha dzimbiri zitha kuperekedwa kuti ziwonjezere moyo wa ntchito.
