Tungsten carbidejẹ agbo ti o jẹ tungsten ati erogba.Lile rẹ jẹ iru si diamond.Awọn ohun-ini kemikali rẹ jẹ iduroṣinṣin pupọ ati pe o jẹ olokiki pupọ ni awọn aaye ile-iṣẹ lọpọlọpọ.Loni, Sidi Xiaobian yoo ba ọ sọrọ nipa ọna iṣelọpọ ti tungsten carbide.
Ni ibamu si awọn ibeere titungsten carbide rolaiwọn, awọn titobi oriṣiriṣi ti tungsten carbide ni a lo fun awọn idi oriṣiriṣi.Awọn irinṣẹ gige Carbide, gẹgẹ bi awọn irinṣẹ gige abẹfẹlẹ V-sókè ẹrọ, alloy didara pẹlu ultrafine subfine tungsten carbide patikulu.Alloy isokuso lilo alabọde patiku tungsten carbide;Awọn alloy fun gige walẹ ati gige eru jẹ ti alabọde tungsten carbide isokuso.Apata ti a lo fun awọn irinṣẹ iwakusa ni lile giga ati awọn ẹru ipa ati lilo tungsten carbide isokuso.Ipa apata kekere, fifuye ipa kekere, pẹlu patiku alabọde tungsten carbide bi ohun elo aise ti awọn ẹya sooro;Ni emphasizing yiya resistance, titẹ resistance ati dada smoothness, ultrafine ultrafine alabọde patiku tungsten carbide ti lo bi aise ohun elo.Ọpa ipa ni akọkọ nlo alabọde ati ohun elo aise tungsten carbide isokuso.
Tungsten carbide ni akoonu erogba imọ-jinlẹ ti 6.128% (50% atomiki).Nigbati akoonu erogba ti tungsten carbide tobi ju akoonu erogba imọ-jinlẹ, erogba ọfẹ yoo han ni tungsten carbide.Iwaju erogba ọfẹ jẹ ki awọn patikulu tungsten carbide ti o wa ni ayika dagba tobi lakoko sisọ, ti o mu ki awọn patikulu carbide cemented ti ko ni deede.Tungsten carbide gbogbogbo nilo erogba ti a so pọ (≥6.07%) ati erogba ọfẹ (≤0.05%), lakoko ti erogba lapapọ da lori ilana iṣelọpọ ati ibiti ohun elo ti carbide simenti.
Labẹ awọn ipo deede, lapapọ erogba ti igbale sintering tungsten carbide nipasẹ ọna paraffin jẹ ipinnu nipataki nipasẹ apapọ akoonu atẹgun ti briquette ṣaaju ki o to sintering.Apakan ti akoonu atẹgun pọ si nipasẹ apakan 0.75, iyẹn ni, lapapọ erogba ti tungsten carbide = 6.13% + akoonu atẹgun% × 0.75 (a ro pe oju-aye didoju wa ni ileru sisun, ni otitọ, lapapọ erogba ti tungsten carbide ni Pupọ awọn ileru igbale kere ju iye ti a ṣe iṣiro) [4] Lapapọ akoonu erogba ti tungsten carbide China le pin ni aijọju si awọn ilana paraffin mẹta.
Vacuum sintered tungsten carbide ni apapọ erogba akoonu ti nipa 6.18± 0.03% (erogba ọfẹ yoo pọ si).Apapọ akoonu erogba ti paraffin epo-eti hydrogen sintering tungsten carbide jẹ 6.13± 0.03%.Apapọ erogba akoonu ti roba hydrogen sintering tungsten carbide jẹ 5.90± 0.03%.Awọn ilana wọnyi ni igba miiran miiran.Nitorinaa, akoonu erogba lapapọ ti tungsten carbide jẹ ipinnu ni ibamu si awọn ipo kan pato.
