Itandukaniro riri hagati ya Carbide ya sima na Steel yihuta (HSS)

Carbide ya sima hamwe nicyuma cyihuta nibisanzwe byamanuka kumashanyarazi ya tungsten (W), byombi bifite imiterere myiza ya termodinamike, kandi birashobora gukoreshwa mugukora ibikoresho byo gutema, imashini ikora ubukonje nubushyuhe bukora, nibindi, ariko, kubera ibintu bitandukanye bigize ibice byombi, biratandukanye kandi mubijyanye nubukanishi no gukoresha.

1. Igitekerezo
Carbide ya sima nigikoresho kivanze kigizwe nicyuma cyangiza nka karubide ya tungsten (WC) hamwe nicyuma gihuza ifu ya cobalt. Izina ry'icyongereza ni Tungsten Carbide / Carbide Cement. Ubushyuhe bwo hejuru bwa karbide buruta ubw'uburebure bwibyuma byihuta bya.

Ibyuma byihuta cyane ni karubone nyinshi-ivanze cyane igizwe na tungsten, molybdenum, chromium, cobalt, vanadium nibindi bintu, bigizwe ahanini na karubide yicyuma (nka karbide ya tungsten, karbide ya molybdenum cyangwa carbide ya vanadium) na ibyuma bya matrix, hamwe na karubone ya 0,7% -1,65%, igiteranyo cyibintu byose bivanga ni 10% -25%, naho izina ryicyongereza ni Umuvuduko mwinshi Ibyuma (HSS).

2. Imikorere
Byombi bifite ibiranga ubukana buhanitse, imbaraga nyinshi, ubukana bwiza, ubukana butukura, kwambara birwanya, kurwanya ubushyuhe nibikorwa, kandi ibyo biranga bizaba bitandukanye kubera amanota atandukanye. Muri rusange, ubukana, ubukana butukura, kwambara no kurwanya ubushyuhe bwa karbide ya sima nibyiza kuruta ibyuma byihuta.

3. Ikoranabuhanga mu musaruro
Igikorwa cyo gukora karbide ya sima gikubiyemo ahanini ifu ya metallurgie yifu, tekinoroji yo gutera inshinge cyangwa uburyo bwo gucapa 3D.

Uburyo bwo gukora ibyuma byihuta cyane birimo tekinoroji ya casting gakondo, tekinoroji yo gusana electroslag, tekinoroji ya powder metallurgie hamwe nubuhanga bwo gutera inshinge.

4. Koresha
Nubwo byombi bishobora gukora ibyuma, ibishushanyo mbonera byakazi hamwe nimirimo ikonje, imikorere yabo iratandukanye. Umuvuduko wo kugabanya ibikoresho bisanzwe bya karbide wikubye inshuro 4-7 ugereranije nibikoresho bisanzwe byihuta byihuta, kandi ubuzima bwa serivisi buba inshuro 5-80. Kubijyanye nububiko, ubuzima bwa serivisi ya karbide ya sima ipfa yikubye inshuro 20 kugeza 150 kurenza iy'ibyuma byihuta bipfa. Kurugero, ubuzima bwumurimo wo gushyushya imitwe ishyushye bipfa bikozwe mubyuma bya 3Cr2W8V inshuro 5.000. Gukoresha imitwe ishyushye gukuramo bipfa gukora YG20 ya sima ya karbide Ubuzima bwa serivisi ni inshuro 150.000.
