Nhanganyaya yeHardfacing uye Yayo Carbide Zvishandiso

Mumakore ekupedzisira hardfacing yakava nyaya yekukura kwakasimba kwakabatana nekupfeka zvinopikisa application. Hardfacing, inozivikanwawo se "Hardsurfacing", iko kushandiswa kwesimbi inovaka kana kupfeka-inodzivirira weld simbi pamusoro pechikamu nenzira yewelding kana kujoinha kuti irambe abrasion, corrosion, high tembiricha, kana kukanganisa. Iko kuiswa kwemajasi akakora emidziyo yakaoma, isingapfeki pachinhu chakasakara kana chitsva chinopfekwa mubasa. Thermal spraying, spray-fuse uye welding maitiro anowanzo shandiswa kuisa iyo hardfacing layer. Iyo alloy yakadaro inogona kuiswa pamusoro, kumucheto, kana kungoti poindi yechikamu chinopfekwa. Welding deposits inogona kushanda pasi uye kutorazve zvikamu zvinowedzera hupenyu hwavo hwesevhisi. Welding ndiyo yakakosha tekinoroji kuzadzisa izvi zvinodiwa uye kushandisa hardfacing alloys. Zvikamu zvemukati zvakaita semacrusher zvinoratidzwa mukupfeka zvinorema uye zvinoda matanho ekudzivirira epamusoro kudzivirira kudhura nguva uye kuderedza mutengo wezvikamu zvinodhura. Iyi nzira yakagamuchirwa mumaindasitiri mazhinji akadai seSimende, Migodhi, Simbi, Petro-kemikari, Simba, Shuga uye Chikafu.

Tungsten carbide ndechimwe chezvinhu zvakaomesesa zviripo zvekushandisa mumaindasitiri. Haikwanise kunyungudutswa nechero Ordinary low tembiricha murazvo. Izvo zvakare zviri nani brittle. Nokuda kwezvinangwa zvakaoma, inopwanyika uye inoshandiswa pamwe chete nesimbi "inosunga". Iyo tungsten carbide particles inowanzovharirwa musimbi chubhu tsvimbo.

ZZBETTER ine akati wandei akadai akaomesesa welding zvinhu seanotevera:

1.Tungsten Carbide Wear Insets:

2.Tungsten Carbide Grits: Tungsten carbide grit inopa kuchengetedzwa kwekugara kwenguva refu munzvimbo dzekupfeka kwakakwira. Inoshandiswa kuchengetedza zvikamu zvinodhura zvakadai semabulldozer blades, mazino emubhaketi, kukuya huni, sando, mazino emagetsi, uye zvakasiyana-siyana zvezvimwe zvinodyiwa. Tungsten Carbide grit inzira inoshanda yekudzivirira muchina uye zvikamu zvemuchina nekupa kuwedzera kwakakosha kwehupenyu hurefu hwezvikamu izvozvo. Izvi zvinoderedza nguva uye zvinoderedza mutengo unobatanidzwa nezvikamu zvisina kudzivirirwa.

3.Composite Tsvimbo dzine Carbide Insets: Aya emhando yepamusoro anoumba tsvimbo anoshandisa yedu carbide inoisa inokupa yakapinza yehasha yekucheka mipendero uye kusimba kunodiwa munzvimbo dzakakosha dzechigayo chako.

4.Nickel Carbide Composite tsvimbo: Nickel carbide composite rods anga ari kuomarara uye kugadzirisa kweakagadzika cutter bits uye anoshandiswa sekudzivirira kupfeka kwezvigadzika uye reamers muindasitiri yemafuta negasi. Iyo hombe tungsten carbide pellets inopa abrasion kuramba ukuwo akapfava pellets achidzivirira matrix kubva pakupfeka uye kukukurwa. Iyo nickel matrix inopa yakakwira-tembiricha corrosion kuramba, inodzivirira zvishoma muviri uye ichibvumira kugadziridzwa kwekucheka uye kudhirowa kwemusoro kushandiswa zvakare.

5.Flexible Welding Tambo: Flexible welding tambo inogadzirwa kubva kucast tungsten carbide, spherical cast tungsten carbide kana musanganiswa wezviviri sechikamu chakaoma, self-fluxing nickel alloy poda yechikamu chekubatanidza, zvinoenderana nechimwe chikamu chemusanganiswa bonding, extrusion kuumba, kuomesa, ndokuzogadzirwa pawaya yenickel.

6.Nickel Silver Tinning tsvimbo: Nickel sirivheri tinning rods ndeye-chinangwa-chinangwa oxyacetylene tsvimbo yebraze welding akasiyana ferrous uye asiri-ferrous simbi, senge simbi, cast iron, anobleable iron, uye mamwe nickel alloys. Iwo anowanzo shandiswa kubatanidza welding yendarira, bhuronzi, uye copper alloys pamwe nekuvaka nzvimbo dzakasakara.

7.Kanda Tungsten Carbide Poda: Cast tungsten carbide powder, inowanzonzi W2C, chinhu chakanyanya kuoma chinoshandiswa mumhando dzakasiyana dzekushandisa. Iine eutectic chimiro, yakakwira kunyungudika uye kuoma, izvo zvinogona kubatsira mukupfeka kudzivirira uye kupfeka zvimiro zvekudzivirira. Nyaya yacho inogadzirwakubva mumusanganiswa wecarbon, tungsten uye tungsten carbide poda uye isirivha/grey muruvara ine yakapinza blocky particle shape.

8.Tungsten Carbide Pellet Welding tsvimbo: Kuenzaniswa ne cast tungsten carbide poda, tungsten carbide pellets ine zvirinani kukanganisa uye kupfeka kuramba. Iyo ine maitiro eimwe-nguva welding pasina reflow soldering. Ma pellets ane denderedzwa; iyo friction coefficient idiki, iyo inogona kuderedza casing kupfeka uye inodhura-inoshanda.

Mubvunzo: Ko hardfacing yakakosha here? 

Hardfacing inogona kuitwa kuburikidza nemhando dzakasiyana-siyana, muchitoro uye mumunda, zvichiita kuti zvive zvakasiyana-siyana uye zvinodhura. Pamusoro pezvo, kushandisa maitiro aya pazvikamu zvitsva zvinogona kuwedzera hupenyu hwesevhisi kusvika ku300%. Zvakadaro, kana iwe wakapfekwa zvikamu zvakaoma, unogona kuchengetedza kusvika 75% maringe nekutsiva mutengo.

Kupedzisa, hardfacing ndiyo nzira inosiyana-siyana yekuvandudza hupenyu hwechikamu chakasakara; hardfacing ndiyo yakanakisa yakasarudzwa maitiro mazuva ano ekudzikisa mutengo wekutsiva; hardfacing inoderedza nguva yekudzikira nekuti zvikamu zvinogara kwenguva refu uye zvishoma zvivharo zvinodikanwa kuti zvitsive; hardfacing inogona kuitwa pane chero zvinhu zvesimbi uchishandisa akasiyana siyana ekugadzira welding maitiro.

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana KUTITUMIRA MAIL pazasi peji rino.
