Otu esi eji mkpanaka Tungsten Carbide Composite

1. Debe elu dị ọcha

Ihe a ga-eji na-etinye mkpanaka carbide composite kwesịrị ka a kpochaa nke ọma na enweghị ihe mgbochi na ihe ndị ọzọ si mba ọzọ. Ịgba aja bụ usoro kachasị amasị; egweri, ihicha waya, ma ọ bụ aja na-eju afọ. Ịgba aja n'elu ga-ebute ihe isi ike na matriks tinning.

2. Okpomọkụ nke ịgbado ọkụ

Jide n'aka na etinyere ngwaọrụ ahụ maka brazing ala. Mgbe ọ ga-ekwe omume, chekwaa ngwaọrụ ahụ n'ime ngwa jig kwesịrị ekwesị.

Gbalịa idowe ọnụ ọnụ ọkụ gị abụọ ma ọ bụ atọ n'akụkụ elu ị na-eji ejiji. Jiri nwayọọ kpoo ọkụ ruo ihe dịka 600°F (315°C) ruo 800°F (427°C), na-ejigide okpomọkụ kacha nta nke 600°F (315°C).

3. Nzọụkwụ ise nke ịgbado ọkụ

(1)Mgbe a ruru okpomọkụ kwesịrị ekwesị, fesa elu ka a ga-eji ntụ ntụ brazing flux. Ị ga-ahụ flux afụ na obụpde ma ọ bụrụ na elu nke gị workpiece bụ ekpo ọkụ nke ọma. Mmụgharị a ga-enyere aka igbochi nguzobe nke oxides na matriks gbazere n'oge ejiji. Jiri ọkụ oxy-acetylene. Nhọrọ ndụmọdụ ga-adabere na ọnọdụ- # 8 ma ọ bụ # 9 maka uwe akwa ebe, # 5, # 6 ma ọ bụ # 7 maka obere mpaghara ma ọ bụ nkuku siri ike. Gbanwee ọkụ na-anọpụ iche nke obere nrụgide na ihe nlele gị setịpụrụ na 15 na acetylene yana 30 na oxygen.

(2)Gaa n'ihu na-ekpo ọkụ n'elu ka a na-eyi ya ruo mgbe njedebe mkpanaka nke carbide na-acha uhie uhie na brazing flux gị na-agba mmiri ma doo anya.

(3)N'ịnọgide na 50 mm ruo 75 mm pụọ n'elu, mee ka okpomọkụ dị n'otu mpaghara gaa na uhie cherry na-acha uhie uhie, 1600°F (871°C). Were mkpanaka brazing gị wee malite tinning elu na ihe dị ka 1/32" ruo 1/16" mkpuchi. Ọ bụrụ na a na-ekpo ọkụ n'elu nke ọma, mkpanaka na-ejuputa ga-asọba ma gbasaa iji soro okpomọkụ. Okpomọkụ na-ezighi ezi ga-eme ka ọla a wụrụ awụ gbasaa. Gaa n'ihu na-ekpo ọkụ wee tie elu ka a yie ya ngwa ngwa ka matriks ahụ gbazere agbaze ga-ejikọta.

(4) Were mkpanaka tungsten carbide composite gị wee malite gbazee akụkụ 1/2" ruo 1". Enwere ike ime ka nke a dịkwuo mfe site n'itinye njedebe n'ime mkpọ mkpọ nke mepere emepe.

(5)Mgbe ejiri mkpanaka ngwakọta kpuchie mpaghara ahụ, jiri tinning matrix hazie carbides na ọnụ kacha nkọ elu. Jiri mgbagharị okirikiri nwere n'ọnụ ọkụ ka ị ghara ikpo oke ebe akwa akwa. Debe itinye uche nke carbide na uwe akwa dị ka o kwere mee.

4. Akpachara anya maka welder

Jide n'aka na ebe a na-arụ ọrụ nwere ikuku nke ọma. Gas na uzuoku sitere na flux ma ọ bụ matrix na-emepụta na-egbu egbu ma nwee ike ịkpata ọgbụgbọ ma ọ bụ ọrịa ndị ọzọ. Onye welder ga-eyi oghere gbara ọchịchịrị #5 ma ọ bụ #7, akwa anya, ntị ntị, ogologo aka uwe, na uwe aka n'oge ọ bụla.

5. Akpachara anya

Ejila mkpara matrix filler gabiga ókè- ọ ga-ebelata pasentị matriks carbide.

Ejila kabides kpoo ọkụ. Ọkụ na-acha akwụkwọ ndụ akwụkwọ ndụ na-egosi oke okpomọkụ na carbides gị.

Oge ọ bụla iberibe carbide gị jụrụ ịbụ tin, a ga-ewepụrịrị ha na ọdọ mmiri ma ọ bụ jiri mkpanaka braz wepụ ha.

A. Mgbe ngwa gị chọrọ ka ị wuo pads n'elu 1/2 ", nke a nwere ike ịchọ a nwayọọ ígwè 1020-1045 pad ekara ka welded gị ngwá ọrụ na-eyi ebe.

B. Mgbe mpaghara gị na-eyiri, mee ka ngwa ahụ dị jụụ. Ejila mmiri ajụkwa oyi. Emeghachila ebe a na-eyi uwe site na ịgbado ọkụ ọ bụla n'akụkụ ya.

6. Otu esi ewepu carbide composite Rod

Iji wepụ ebe ị na-eji ejiji mgbe emechara ya, kpoo mpaghara carbide ka ọ bụrụ ụcha ọbara ọbara na-acha uhie uhie ma jiri ụdị ígwè dị ka ahịhịa wepụ carbide grits na matriks n'elu. Agbalịla iji ọkụ gị naanị pụọ na grits carbide na matrix.
