Nigute Ukoresha Tungsten Carbide Igizwe na Rod

1. Komeza kugira isuku

Ibikoresho bigomba gukoreshwamo karbide bigomba gusukurwa neza kandi bitarangiritse kandi nibindi bintu by’amahanga. Sandblasting nuburyo bwatoranijwe; gusya, koza insinga, cyangwa umusenyi nabyo birashimishije. Umusenyi wo hejuru uzatera ingorane muri matrike.

2. Ubushyuhe bwo gusudira

Menya neza ko igikoresho gishyizwe kumurongo wo hasi. Mugihe bishoboka, shyira igikoresho muburyo bukwiye.

Gerageza kugumisha isonga yumuriro wawe kuri santimetero ebyiri kugeza kuri eshatu hejuru yambaye. Buhoro buhoro ushushe kugeza kuri 600 ° F (315 ° C) kugeza 800 ° F (427 ° C), ukomeza ubushyuhe buke bwa 600 ° F (315 ° C).

3. Intambwe eshanu zo gusudira

(1)Iyo ubushyuhe bukwiye bugeze, suka hejuru kugirango wambare ifu ya flux. Uzabona flux bubble hanyuma ubire niba ubuso bwibikorwa byawe bishyushye bihagije. Iyi flux izafasha gukumira ishingwa rya oxyde muri matrike yashongeshejwe mugihe cyo kwambara. Koresha itara rya oxy-acetylene. Guhitamo inama bizaterwa nuko ibintu bimeze - # 8 cyangwa # 9 byo kwambara ahantu hanini, # 5, # 6 cyangwa # 7 kubice bito cyangwa impande zombi. Hindura urumuri ruke rutagira aho rubogamiye hamwe n'ibipimo byawe byashyizwe kuri 15 kuri acetylene na 30 kuri ogisijeni.

(2)Komeza gushyushya hejuru kugirango wambare kugeza karbide igizwe ninkoni irangiye itukura kandi flux yawe ya flux iratemba kandi irasobanutse.

(3)Kuguma kuri mm 50 kugeza kuri mm 75 uvuye hejuru, shyira ubushyuhe ahantu hamwe kugeza kuri cheri itukura, 1600 ° F (871 ° C). Fata inkoni yawe ya brazing hanyuma utangire gutobora hejuru hamwe na 1/32 ”kugeza 1/16”. Niba ubuso bushyushye neza, inkoni yuzuza izatemba kandi ikwirakwize kugirango ikurikirane ubushyuhe. Ubushyuhe budakwiye buzatera icyuma gishongeshejwe. Komeza gushyushya hanyuma uhindure hejuru kugirango wambare vuba nkuko matrix yuzuza matrix izahuza.

(4) Fata inkoni ya karubide ya tungsten hanyuma utangire gushonga igice cya 1/2 "kugeza 1". Ibi birashobora koroha mugushira impera mumashanyarazi afunguye.

(5)Agace kamaze gutwikirwa ninkoni ikomatanya, koresha matrike ya tinning kugirango utegure karbide hamwe nuruhande rukomeye hejuru. Koresha uruziga ruzengurutse urumuri kugirango wirinde gushyushya ahantu wambaye. Komeza kwibanda kuri karbide mukwambara uko bishoboka kwose.

4. Kwirinda gusudira

Menya neza ko aho ukorera uhumeka neza. Gazi n'umwotsi biterwa na flux cyangwa matrix ni uburozi kandi birashobora kubyara isesemi cyangwa izindi ndwara. Umudozi agomba kwambara # 5 cyangwa # 7 lens yijimye, inkweto zijisho, gutwi, amaboko maremare, na gants igihe cyose mugihe cyo kubisaba.

5. Icyitonderwa

Ntukoreshe urugero rwinshi rwuzuza matrix- bizagabanya ijanisha rya karbide.

Ntugashyuhe karbide. Icyatsi kibisi cyerekana ubushyuhe bwinshi kuri karbide yawe.

Igihe icyo ari cyo cyose ibice bya karbide byanze kuba amabati, bigomba kuvanwa mu kidiba cyangwa bigakurwaho inkoni.

A. Mugihe gusaba kwawe bisaba ko wubaka amakariso hejuru ya 1/2 ”, ibi birashobora gusaba icyuma cyoroheje 1020-1045 kimeze nk'icyuma cyo gusudira mugikoresho cyawe aho wambaye.

B. Agace kawe kamaze kwambara, shyira igikoresho buhoro. Ntuzigere ukonjesha amazi. Ntugashyushya ahantu wambaye ukora gusudira hafi yacyo.

6. Nigute ushobora gukuramo karbide igizwe na Rod

Kugira ngo ukureho agace kawe wambaye nyuma yo guhindurwa, shyushya agace ka karbide kumabara atukura kandi ukoreshe icyuma cyo mu bwoko bwicyuma kugirango ukureho karbide grits na matrix hejuru. Ntugerageze kuva kure ya karbide grits na matrix hamwe numuriro wawe wenyine.
