Uyisebenzisa njani iTungsten Carbide Composite Rod

1. Gcina ubuso bucocekile

Izinto eziza kufakwa kuyo intonga ye-carbide kufuneka ihlambuluke ngokucokisekileyo kwaye ingabikho kwi-corrosion kunye nezinye izinto zangaphandle. I-Sandblasting yindlela ekhethiweyo; nokusila, ukubrasha ucingo, okanye ukugalela isanti nako kuyanelisa. Ukuqhunyiswa kwesanti kumphezulu kuya kubangela ubunzima kwi-tinning matrix.

2. Ubushushu be-welding

Qinisekisa ukuba isixhobo sibekwe kwindawo yokubeka isandla phantsi. Xa kunokwenzeka, khusela isixhobo kwindawo efanelekileyo yejig.

Zama ukugcina incam yetotshi yakho i-intshi ezimbini ukuya kwezintathu ukusuka kumphezulu owunxibileyo. Kancinci ukufudumeza ukuya kuma-600°F (315°C) ukuya kuma-800°F (427°C), ugcine ubushushu obuncinane obuyi-600°F (315°C).

3. Amanyathelo amahlanu e-welding

(1)Xa ubushushu obufanelekileyo bufikelelwe, fafaza umphezulu ukuba unxibe ngebrazing flux powder. Uya kubona iqamza eliguquguqukayo kwaye ubilise ukuba umphezulu womsebenzi wakho ushushu ngokwaneleyo. Le ntsholongwane iya kunceda ukuthintela ukubunjwa kwe-oxides kwi-matrix etyhidiweyo ngexesha lokugqoka. Sebenzisa itotshi ye-oxy-acetylene. Ukukhetha ingcebiso kuya kuxhomekeka kwimeko- #8 okanye #9 yokunxiba iindawo ezinkulu, #5, #6 okanye #7 kwiindawo ezincinci okanye iikona ezixineneyo. Lungisa idangatye elisezantsi loxinzelelo olungathathi hlangothi kunye neegeyiji zakho ezibekwe kwi-15 kwi-acetylene kunye ne-30 kwi-oxygen.

(2)Qhubeka ukufudumeza umphezulu ukuze unxibe de iziphelo zentonga ye-carbide zibomvu kwaye i-brazing flux yakho imanzi kwaye icacile.

(3)Ukuhlala kwi-50 mm ukuya kwi-75 mm ukusuka kumphezulu, beka ubushushu kwindawo enye kwindawo ebomvu yecherry ebomvu, 1600 ° F (871 ° C). Thatha intonga yakho yokuqhafaza kwaye uqalise ukuthambisa umphezulu malunga ne-1/32 "ukuya kwi-1/16" yesigqubuthelo esikhulu. Ukuba umphezulu ushushu ngokufanelekileyo, intonga yokuzalisa iya kuhamba kwaye isasazeke ukulandela ubushushu. Ubushushu obungafanelekanga buya kubangela ukuba isinyithi esinyibilikisiweyo sibe ngamaso. Qhubekeka ubushushu kwaye ke umphezulu wetoti ukuze unxibe ngokukhawuleza njengoko i-matrix yokugcwalisa etyhidiweyo iya kudibanisa.

(4) Thatha intonga yakho ye-tungsten carbide kwaye uqale ukunyibilika kwi-1/2 "ukuya kwi-1" icandelo. Oku kunokwenziwa lula ngokufaka isiphelo kwitoti evulekileyo ye-flux.

(5)Emva kokuba indawo igutyungelwe yintonga edibeneyo, sebenzisa i-matrix ye-tinning ukulungiselela i-carbides kunye neyona nto ibukhali phezulu. Sebenzisa isindululo sesetyhula kunye nencam yetotshi ukuze ungatshisi ngokugqithisileyo indawo enxityisiweyo. Gcina i-concentration ye-carbide kwi-dressing ixinene ngokunokwenzeka.

4. Ukulumkisa kwi-welder

Qinisekisa ukuba indawo ekusetyenzwa kuyo ingena umoya. Irhasi kunye nomsi oveliswa yi-flux okanye imatrix iyityhefu kwaye inokuvelisa isicaphucaphu okanye ezinye izigulo. Umshicileli kufuneka anxibe #5 okanye #7 ilensi emnyama, iimpahla zamehlo, iindlebe, imikhono emide, kunye neeglavu ngamaxesha onke ngexesha lokufaka isicelo.

5. Isilumkiso

Musa ukusebenzisa izixa ezigqithisileyo ze-filler matrix rod- iyakuhlambulula ipesenti ye-carbide matrix.

Musa ukutshisa i-carbides. Ukukhanya okuluhlaza kubonisa ubushushu obuninzi kakhulu kwi-carbides yakho.

Naliphi na ixesha iziqwenga zakho ze-carbide zingavumi ukuba yi-tin, kufuneka zikhutshwe kwi-puddle okanye zisuswe ngentonga yokuqhafaza.

A. Xa isicelo sakho sifuna ukuba wakhe iipads phezu kwe-1/2”, oku kunokufuna intsimbi ethambileyo eyi-1020-1045 iphedi emiliselwe ukuba idityaniswe kwisixhobo sakho kwindawo yokunxiba.

B. Emva kokuba indawo yakho inxityiwe, sipholisa isixhobo kancinane. Ungaze uphole ngamanzi. Musa ukuyifudumeza kwakhona indawo enxityiweyo ngokwenza nayiphi na i-welding ekufutshane nayo.

6. Indlela yokususa i-carbide composite Rod

Ukususa indawo yakho edibeneyo enxibileyo emva kokuba iphelile, fudumeza indawo ye-carbide kumbala obomvu obomvu kwaye usebenzise ibrashi yohlobo lwesinyithi ukukhupha i-carbide grits kunye ne-matrix ebusweni. Sukuzama ukusuka kwigrits ye-carbide kunye ne-matrix ngetotshi yakho yodwa.
