Teeb meem thiab ua rau Carbide txiav cov cuab yeej

Tungsten carbide brazed txiav cov cuab yeej feem ntau muaj qee qhov teeb meem brazing tom qab brazing. Hauv qab no yog qee qhov teeb meem braze thiab lawv cov laj thawj.

1. Tungsten carbide taub hau tawg thiab tawg

Cov laj thawj tseem ceeb ntawm kev tawg thiab tawg ntawm lub brazing yog raws li hauv qab no:

A: Lub kaum sab xis ntawm qhov ntxhib ntawm qhov chaw hauv qab ntawm lub taub hau cutter thiab lub hauv paus ntawm lub taub hau cutter tsis tsim nyog thiab qhov chaw brazing tsawg dhau, yog li cov khoom siv vuam thiab cov flux tsis tuaj yeem muab faib tag nrho.

B: Cov hlau tsis sib haum yog luv luv luv ntawm lub ntsej muag braze, uas ua rau muaj kev sib cuag ncaj qha ntawm lub hauv qab kawg ntawm cov ntsiab lus carbide thiab lub hauv paus hlau, nrog rau cov khoom braze faib ntawm lawv.

C: Lub sijhawm cua sov thiab cua txias yog nrawm dhau los yog qeeb dhau

D: Qhov kub ntawm soldering yog siab dhau. Txij li thaum lub coefficient ntawm linear expansion ntawm cemented carbide yog tsawg heev, yog hais tias qhov kub thiab txias yog siab dhau heev lawm, thermal stress loj yuav raug generated nyob rau hauv lub sib koom tes, uas tshaj lub tensile lub zog ntawm cemented carbide, uas yuav ua rau tawg ntawm cemented carbide.

2. Braze porosity

Cov laj thawj tseem ceeb rau qhov teeb meem brazing nrog pores yog:

A: Yog tias qhov kub thiab txias dhau lawm, nws yuav ua rau zinc foaming nyob rau hauv cov khoom siv tab

B: Yog tias qhov ntsuas kub qis dhau lawm, cov flux yuav tsis yaj tag, ua rau foaming

3. Carbide taub hau poob

Cov teeb meem tseem ceeb ntawm carbide ntsis poob yog vim:

A: Kev xaiv ntawm cov khoom siv tsis raug, nws tsis tuaj yeem ntub nrog cov hlau hauv paus, lossis qhov chaw ntub dej tsawg dhau

B: Qhov kub thiab txias yog qhov tsawg dhau, thiab cov hlau tsis tuaj yeem nkag mus, ua rau txo qis ntawm lub zog ntawm lub braze thiab lub taub hau txiav poob.

C: Cov khoom siv me me dhau, thiab lub zog raug txo

D: Qhov kub thiab txias heev, thiab ib feem ntawm cov solder overflows

E: Cov khoom siv solder tsis yog concentric, ua rau tsis sib npaug ntawm cov khoom siv, ua ib feem ntawm lub brazing seam cuav brazing, thiab tsis txaus brazing lub zog.

Yog tias koj txaus siab rau tungsten carbide txiav cov cuab yeej thiab xav tau cov ntaub ntawv ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
