Indlela yokusebenzisa i-Tungsten Carbide Composite Rod

1. Gcina ubuso buhlanzekile

Izinto okumele kufakwe kuzo induku ye-carbide composite kufanele zihlanzwe kahle futhi zingabi nokugqwala nezinye izinto zangaphandle. I-sandblasting iyindlela ekhethwayo; ukugaya, ukuxubha ucingo, noma ukugcotshwa kwesihlabathi nakho kuyagculisa. Ukuqhunyiswa kwesihlabathi kuzodala ubunzima ku-matrix yokubopha.

2. Izinga lokushisa lokushisela

Qiniseka ukuthi ithuluzi libekwe endaweni yokubhulaza ngesandla. Uma kungenzeka, vikela ithuluzi endaweni efanele ye-jig.

Zama ukugcina ichopho lethoshi lakho ngamayintshi amabili kuya kwamathathu lisuke endaweni oyigqokile. Shisisa kancane kancane uye ku-600°F (315°C) ukuya ku-800°F (427°C), ugcine izinga lokushisa elincane elingu-600°F (315°C).

3. Izinyathelo Ezinhlanu Zokushisela

(1)Lapho izinga lokushisa elifanele lifinyelelwa, ufafaze ubuso obuzogqokiswa nge-brazing flux powder. Uzobona ibhamuza le-flux bese ubilisa uma ingaphezulu lomsebenzi wakho lishisisa ngokwanele. Lokhu kugeleza kuzosiza ukuvimbela ukwakheka kwama-oxides ku-matrix encibilikisiwe ngesikhathi sokugqoka. Sebenzisa ithoshi ye-oxy-acetylene. Ukukhethwa kwethiphu kuzoncika esimweni- #8 noma #9 ngokugqoka izindawo ezinkulu, #5, #6 noma #7 ezindaweni ezincane noma amakhona aqinile. Lungisa ilangabi elingathathi hlangothi elinengcindezi ephansi ngamageji akho asethwe kokuthi 15 ku-acetylene kanye nama-30 kumoya-mpilo.

(2)Qhubeka ushisisa indawo ukuze ugqokiswe kuze kube yilapho imikhawulo ye-carbide composite ibomvu futhi i-brazing flux yakho iwuketshezi futhi icacile.

(3)Ukuhlala ku-50 mm kuya ku-75 mm ngaphandle kwendawo, beka ukushisa endaweni eyodwa endaweni ebomvu ye-cherry, 1600°F (871°C). Thatha i-brazing rod yakho bese uqala uku-thina indawo engaphezulu ngekhava ewugqinsi engu-1/32" ukuya ku-1/16". Uma ubuso bushiswa kahle, induku yokugcwalisa izogeleza futhi isakaze ukulandela ukushisa. Ukushisa okungafanele kuzokwenza insimbi encibilikisiwe ibe ubuhlalu. Qhubeka nokushisa bese uthina indawo engaphezulu ukuze igqokwe ngokushesha njengoba i-matrix yesigcwalisi esincibilikisiwe izobopha.

(4) Thatha induku yakho eyinhlanganisela ye-tungsten carbide bese uqala ukuncibilika engxenyeni engu-1/2 "kuya ku-1". Lokhu kungenziwa kube lula ngokucwilisa isiphetho ethini elivulekile lokugeleza.

(5)Ngemuva kokuthi indawo imbozwe induku eyinhlanganisela, sebenzisa i-matrix yokufaka ukuze uhlele ama-carbides ngomkhawulo obukhali kakhulu. Sebenzisa ukunyakaza okuyindilinga ngethiphu yethoshi ukuze ungashisi ngokweqile indawo egqokile. Gcina ukugcwala kwe-carbide ekugqokeni kuminyene ngangokunokwenzeka.

4. Ukuqapha kwe-welder

Qinisekisa ukuthi indawo yokusebenza inomoya omuhle. Igesi nentuthu ekhiqizwe i-flux noma i-matrix inobuthi futhi ingadala isicanucanu noma ezinye izifo. Umshiseli kufanele agqoke ilensi engu-#5 noma engu-#7 emnyama, okokugqoka kwamehlo, izixhumi ezindlebeni, imikhono emide, namagilavu ​​ngaso sonke isikhathi ngesikhathi sokufaka isicelo.

5. Isexwayiso

Ungasebenzisi amanani eqile we-filler matrix rod- izonciphisa iphesenti le-matrix ye-carbide.

Ungawashisi ngokweqile ama-carbides. Ukukhanya okuluhlaza kubonisa ukushisa okukhulu kuma-carbides akho.

Noma nini lapho izingcezu zakho ze-carbide zenqaba ukuba ithini, kufanele zikhishwe echibini noma zisuswe ngenduku yokufaka.

A. Uma isicelo sakho sidinga ukuthi wakhe amaphedi ngaphezu kwe-1/2”, lokhu kungase kudinge insimbi enomumo ongu-1020-1045 emaphakathi ukuthi ishiselwe ethuluzini lakho endaweni egugile.

B. Ngemva kokuba indawo yangakini isigqokile, pholisa ithuluzi kancane. Ungalokothi uphole ngamanzi. Ungashisi kabusha indawo egqokile ngokwenza noma yikuphi ukushisela eduze kwayo.

6. Indlela yokususa i-carbide composite Rod

Ukuze ususe indawo yakho eyinhlanganisela egqokile ngemva kokuba isifiphele, shisisa indawo ye-carbide ibe nombala obovu ongalungi futhi usebenzise ibhulashi lohlobo lwensimbi ukuze ukhiphe amagridi e-carbide kanye ne-matrix phezulu. Ungazami ukusuka ku-grits ye-carbide kanye ne-matrix ngethoshi lakho lodwa.
