Chiyambi cha Hardfacing ndi Zida Zake za Carbide

M'zaka zapitazi hardfacing idakhala nkhani yachitukuko chachikulu chokhudzana ndi mavalidwe osamva. Hardfacing, yomwe imadziwikanso kuti "Hardsurfacing", ndikugwiritsa ntchito zitsulo zowotcherera zomangira kapena zosamva kuvala pamwamba pa gawo pogwiritsa ntchito kuwotcherera kapena kujowina kuti zisawonongeke, dzimbiri, kutentha kwambiri, kapena kuyaka. Ndiko kuyika kwa zokutira zolimba, zolimba, zosavala pa chinthu chong'ambika kapena chatsopano chomwe chimatha kuvala muutumiki. Kupopera mbewu kwa matenthedwe, kupopera mbewu mankhwalawa ndi njira zowotcherera nthawi zambiri zimagwiritsidwa ntchito popaka wosanjikiza wokhazikika. Aloyi yotereyi imatha kuyikidwa pamwamba, m'mphepete, kapena pagawo la gawo lomwe lingavale. Kuwotcherera madipoziti amatha kugwira ntchito pamwamba ndikubwezeretsanso zigawo zomwe zimakulitsa moyo wawo wautumiki. Kuwotcherera ndi ukadaulo wofunikira kuti mukwaniritse zofunikirazi komanso kugwiritsa ntchito ma alloys olimba. Zigawo zazikuluzikulu monga ma crushers amavala kwambiri ndipo zimafunikira njira zotetezera pamwamba kuti zipewe kutsika mtengo komanso kuchepetsa ndalama zosinthira zodula. Njirayi yavomerezedwa m'mafakitale ambiri monga Simenti, Migodi, Zitsulo, Petro-chemical, Mphamvu, Nzimbe ndi Chakudya.

Tungsten carbide ndi imodzi mwazinthu zovuta kwambiri zomwe zimagwiritsidwa ntchito m'mafakitale. Sizingasungunuke ndi Lawi lililonse lotentha lotsika. Komanso ndi m'malo brittle. Zolinga zolimba, zimaphwanyidwa ndikugwiritsidwa ntchito pamodzi ndi chitsulo "chomangiriza". Ma tungsten carbide particles nthawi zambiri amatsekeredwa mu ndodo yachitsulo.

ZZBETTER ili ndi zida zingapo zowotcherera zolimba motere:

1.Tungsten Carbide Wear Insert:

2.Zakudya za Tungsten Carbide: Tungsten carbide grit imapereka chitetezo chokhalitsa kwanthawi yayitali m'malo okhala ndi ma abrasive kwambiri. Amagwiritsidwa ntchito kuteteza ziwalo zamtengo wapatali monga bulldozer blades, mano a ndowa, kugaya nkhuni, nyundo, mano a trencher, ndi zina zambiri zomwe zimagwiritsidwa ntchito. Tungsten Carbide grit ndi njira yabwino yotetezera makina ndi zida zamakina popereka chiwonjezeko chachikulu cha moyo wautali wa magawowo. Izi zimachepetsa nthawi yopuma ndikuchepetsa mtengo womwe umakhudzidwa ndi magawo osatetezedwa.

3.Ndodo Zophatikizika Zokhala ndi Carbide Insert: Ndodo zophatikizika izi zimagwiritsa ntchito zoyika zathu za carbide zomwe zimakupatsirani m'mphepete mwaukali komanso kulimba kofunikira pazida zofunika kwambiri za mphero.

4.Nickel Carbide Composite Ndodo: Ndodo za nickel carbide zakhala zolimba ndikukonza zodulira zosasunthika ndipo zimagwiritsidwa ntchito ngati zodzitchinjiriza zodzitchinjiriza ndi zowongolera mumakampani amafuta ndi gasi. Ma pellets akuluakulu a tungsten carbide amapereka kukana kwa abrasion pomwe ma pellets abwino amateteza matrix kuti asawonongeke komanso kukokoloka. Matrix a nickel amapereka kutentha kwambiri kwa dzimbiri, kuteteza thupi laling'ono komanso kulola kukonzanso kodula ndikubowolanso mutu.

5.Flexible Welding Chingwe: Chingwe chowotcherera chosinthika chimapangidwa kuchokera ku tungsten carbide, spherical cast tungsten carbide kapena osakaniza awiriwo ngati gawo lolimba, ufa wodzigudubuza wa nickel alloy pagawo lomangirira, malinga ndi gawo lina la kuphatikiza kosakanikirana, kuumba kwa extrusion, kuyanika, kenako amapangidwa pa waya wa nickel.

6.Ndodo za Nickel Silver Tinning: Ndodo za siliva za nickel ndizomwe zimagwiritsidwa ntchito nthawi zonse powotcherera zitsulo zosiyanasiyana zachitsulo komanso zopanda chitsulo, monga chitsulo, chitsulo chosungunuka, chitsulo chosungunuka, ndi ma aloyi a faifi tambala. Nthawi zambiri amagwiritsidwa ntchito pophatikiza zowotcherera zamkuwa, zamkuwa, zamkuwa komanso kupanga malo owonongeka.

7.Ponyani Tungsten Carbide Powder: Cast tungsten carbide ufa, womwe umatchedwa W2C, ndi chinthu cholimba kwambiri chomwe chimagwiritsidwa ntchito m'njira zosiyanasiyana. Ndi kapangidwe ka eutectic, malo osungunuka kwambiri komanso kuuma, komwe kungathandize pakudzitchinjiriza ndi kuvala kukana. Zinthuzo zimapangidwakuchokera ku kuphatikiza kwa kaboni, tungsten ndi tungsten carbide ufa ndipo ndi wasiliva/imvi mumtundu wokhala ndi mawonekedwe akuthwa a tinthu tating'ono.

8.Ndodo zowotcherera za Tungsten Carbide Pellet: Poyerekeza ndi ufa wa tungsten carbide, ma pellets a tungsten carbide amakhala ndi mphamvu komanso kukana kuvala. Ili ndi mawonekedwe a kuwotcherera nthawi imodzi popanda reflow soldering. Ma pellets ndi ozungulira; friction coefficient ndi yaying'ono, yomwe ingachepetse kuvala kwa casing komanso yotsika mtengo.

Q: Kodi hardfacing ndiyofunika? 

Kuyika molimba kumatha kuchitika pogwiritsa ntchito njira zosiyanasiyana, m'sitolo ndi m'munda, zomwe zimapangitsa kuti zikhale zosunthika komanso zotsika mtengo. Kuphatikiza apo, kugwiritsa ntchito njirayi pazinthu zatsopano kumatha kukulitsa moyo wautumiki mpaka 300%. Komabe, ngati mutavala zida zolimba, mutha kusunga mpaka 75% poyerekeza ndi mtengo wosinthira.

Pomaliza, hardfacing ndiyo njira yosunthika kwambiri yopititsira patsogolo moyo wa gawo lotha; hardfacing ndiyo njira yosankhidwa bwino kwambiri masiku ano yochepetsera mtengo wosinthira; hardfacing imachepetsa nthawi yopumira chifukwa magawo amakhala nthawi yayitali ndipo kutsekeka kochepa kumafunika kuti m'malo mwake; hardfacing akhoza kuchitidwa pa chilichonse zitsulo ntchito zosiyanasiyana njira kuwotcherera.

Ngati mukufuna zambiri zamtundu wa tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZENI MAIL pansi pa tsambali.
