Mokhoa oa ho sebelisa Tungsten Carbide Composite Rod

1. Boloka bokaholimo bo hloekile

Lisebelisoa tseo molamu oa motsoako oa carbide o lokelang ho sebelisoa ho tsona li lokela ho hloekisoa ka ho feletseng 'me li se ke tsa senyeha le lintho tse ling tse tsoang linaheng tse ling. Sandblasting ke mokhoa o ratoang; ho sila, ho borashe ka terata, kapa ho roala lehlabathe le tsona lia khotsofatsa. Ho qhomisa lehlabathe bokaholimo ho tla baka bothata ho matrix a tinning.

2. Mocheso oa ho cheselletsa

Etsa bonnete ba hore sesebelisoa se behiloe molemong oa ho theola letsoho. Ha ho khoneha, boloka sesebelisoa sebakeng se loketseng sa jig.

Leka ho boloka ntlha ea toche ea hau ka lisenthimithara tse peli ho isa ho tse tharo ho tloha sebakeng seo u se apereng. Butle-butle chesa pele ho hoo e ka bang 600°F (315°C) ho ea ho 800°F (427°C), ho boloka mocheso o fokolang oa 600°F (315°C).

3. Mehato e Mehlano ea ho tjheseletsa

(1)Ha mocheso o nepahetseng o fihla, fafatsa holim'a metsi ho apesoa ka phofo ea brazing flux. U tla bona bubble ea flux ebe u pheha haeba bokaholimo ba mosebetsi oa hau bo futhumetse ka ho lekaneng. Phallo ena e tla thusa ho thibela ho thehoa ha li-oxide ka har'a matrix a qhibilihisitsoeng nakong ea ho apara. Sebelisa toche ea oxy-acetylene. Khetho ea malebela e tla ipapisa le boemo- #8 kapa #9 bakeng sa ho apara libaka tse kholo, #5, #6 kapa #7 bakeng sa libaka tse nyane kapa likhutlo tse thata. Fetola lelakabe le sa nke lehlakore le nang le khatello e tlase 'me li-gauge tsa hau li behiloe ho 15 ho acetylene le 30 ho oksijene.

(2)Tsoela pele ho futhumatsa bokaholimo ho apara ho fihlela lipheletso tsa molamu oa carbide li le khubelu 'me brazing flux ea hau e le metsi ebile e hlakile.

(3)Ha u le 50 mm ho isa ho 75 mm ho tloha holim'a metsi, beha mocheso sebakeng se le seng ho ea ho bofubelu ba cherry e lerootho, 1600 ° F (871 ° C). Nka molamu oa hau oa ho betla 'me u qale ho koala bokaholimo ka sekoahelo se teteaneng sa 1/32" ho isa ho 1/16". Haeba bokaholimo bo futhumetse hantle, molamu oa ho tlatsa o tla phalla 'me o hasane ho latela mocheso. Mocheso o sa lokang o tla etsa hore tšepe e qhibilihisitsoeng e be lifaha. Tsoela pele ho futhumala ebe o kenya thini holim'a metsi hore a apesoe kapele kamoo matrix a molt a tla kopana.

(4) Nka molamu oa hau oa tungsten carbide 'me u qale ho qhibiliha karolo ea 1/2 "ho isa ho 1". Sena se ka nolofalloa ka ho kenya pheletso ka har'a lekotikoti le bulehileng la phallo.

(5)Ka mor'a hore sebaka se koaheloe ke molamu o kopantsoeng, sebelisa matrix a tinning ho hlophisa li-carbides ka bohale bo phahameng ka ho fetisisa. Sebelisa motsamao oa selikalikoe o nang le ntlha ea toche ho thibela ho chesa haholo sebakeng se apereng. Boloka khatello ea carbide ka har'a moaparo e le e teteaneng ka hohle kamoo ho ka khonehang.

4. Tlhokomelo bakeng sa welder

Etsa bonnete ba hore sebaka sa mosebetsi se na le moea o motle. Khase le mosi tse hlahisoang ke flux kapa matrix li chefo 'me li ka baka ho nyekeloa ke pelo kapa mafu a mang. The welder e tlameha ho roala lense e lefifi ea #5 kapa #7, liaparo tsa mahlo, li-earplugs, matsoho a malelele, le liatlana ka linako tsohle nakong ea kopo.

5. Tlhokomeliso

Se ke oa sebelisa litekanyo tse feteletseng tsa "filler matrix rod" - e tla hlapolla peresente ea carbide matrix.

U se ke ua chesa haholo li-carbides. Leseli le letala le bontša mocheso o mongata haholo ho li-carbide tsa hau.

Nako le nako ha likotoana tsa hau tsa carbide li hana ho ba thini, li tlameha ho ntšoa ka har'a puddle kapa li tlosoe ka molamu oa brazing.

K. Ha kopo ea hau e hloka hore u hahe liphaephe ho feta 1/2”, sena se ka hloka hore tšepe e bonolo e nang le sebopeho sa 1020-1045 e kenngoe ho sesebelisoa sa hau sebakeng sa ho roala.

B. Kamora hore sebaka sa heno se apesoe, pholisa sesebelisoa butle. Le ka mohla u se ke ua pholile ka metsi. U se ke ua futhumatsa sebaka se apereng ka ho kenya welding leha e le efe haufi le eona.

6. Mokhoa oa ho tlosa "carbide composite Rod".

Ho tlosa sebaka sa hau se kopantsoeng se apereng ka mor'a hore se fokotsehe, futhumatsa sebaka sa carbide ho 'mala o mofubelu o lerootho' me u sebelise borashe ba mofuta oa tšepe ho tlosa grits ea carbide le matrix holim'a metsi. Se ke oa leka ho suthela hole le grits ea carbide le matrix ka toche ea hau feela.
