Izinkinga kanye Izimbangela Carbide Cutting Amathuluzi

Amathuluzi okusika ama-Tungsten carbide brazed ngokuvamile anezinkinga zokugqama ngemuva kokubhula. Ngezansi ezinye zezinkinga ze-braze nezimbangela zazo.

1. Ukuphuka nokuqhekeka kwethiphu ye-tungsten carbide

Izizathu eziyinhloko zokuphuka nokuqhekeka kwe-brazing yilezi ezilandelayo:

A: I-angle ye-rough surface phakathi kwendawo engaphansi yekhanda lokusika kanye nesisekelo sekhanda lokusika ayifanele futhi isikhala sokubhinca sincane kakhulu, ngakho-ke impahla yokushisela kanye ne-flux ayikwazi ukusatshalaliswa ngokuphelele.

B:  Amalugi e-solder angafani mafushane kakhulu uma kuqhathaniswa nobuso be-braze, okuholela ekuxhumaneni okuqondile phakathi komkhawulo ophansi wethiphu ye-carbide nesisekelo sensimbi, okusatshalaliswa kwe-braze phakathi kwawo.

C: Izikhathi zokushisisa nokupholisa ziyashesha kakhulu noma zihamba kancane

D: Izinga lokushisa lokunamathisela liphezulu kakhulu. Njengoba i-coefficient yokunwetshwa komugqa we-carbide enosimende iphansi kakhulu, uma izinga lokushisa liphezulu kakhulu, ukucindezeleka okukhulu okushisayo kuzokhiqizwa ekuhlanganyeleni, okudlula amandla aqinile we-carbide enosimende, okuzoholela ekuqhekekeni kwe-carbide enosimende.

2. I-Braze porosity

Izizathu eziyinhloko zale nkinga yokubhoboza ngama-pores yilezi:

IMP: Uma izinga lokushisa lokunamathisela liphezulu kakhulu, lizobangela i-zinc igwebu kokubalulekile kwethebhu ye-solder

B: Uma izinga lokushisa le-solder liphansi kakhulu, i-flux ngeke incibilike ngokuphelele, okuholela ekuphumeni kwamagwebu.

3. Ithiphu ye-carbide iyawa

Izinkinga eziyinhloko ngethiphu ye-carbide ziyawa ngenxa yokuthi:

A: Ukukhethwa kwempahla ye-solder akulungile, akukwazi ukumanziswa ngesisekelo sensimbi, noma indawo emanzisiwe incane kakhulu.

B: Izinga lokushisa le-solder liphansi kakhulu, futhi i-solder ayingeni ngokugcwele, okuholela ekwehleni kwamandla e-braze kanye nekhanda lokusika liyawa.

C: Impahla ye-solder incane kakhulu, futhi amandla ayancipha

D: Izinga lokushisa liphezulu kakhulu, futhi ingxenye ye-solder iyachichima

E: Impahla ye-solder ayigxili, okuholela ekusabalaliseni okungalingani kwe-solder, okwenza ingxenye ye-brazing brazing brazing yamanga, namandla anganele okubhula.

Uma uthanda amathuluzi okusika i-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE I-MEyili ezansi ekhasini.
