Tungsten ibikoresho byo gukata karbide - amenyo yinganda, akoreshwa cyane mugukora ibikoresho byingenzi

Igikorwa cyo gukata kibarirwa hafi 90% yimashini ikora.Igikoresho ni "iryinyo" ryibikoresho byimashini zinganda, bigira ingaruka kuburyo butaziguye murwego rwo gutunganya inganda zikora.Gukata bivuga gukata ibintu birenze hejuru yumurimo wakazi, kugirango umenye neza ko igihangano cya geometrie, uburinganire bwuzuye, ubwiza bwubuso nibindi bice byubushakashatsi bwibisabwa muburyo bwo gutunganya, bingana na 90% byimirimo yose yo gutunganya.Gukata mubisanzwe bigerwaho mugukata ibikoresho byimashini, kandi igikoresho nigikoresho cyingenzi gikoreshwa, kuko "amenyo" yibikoresho byimashini zinganda, ubwiza bwayo bugira ingaruka kuburyo butaziguye ku musaruro w’ikoranabuhanga rikora imashini, gukora neza n’ubuziranenge bw’ibicuruzwa.Gukata ibikoresho hejuru yabatanga ibikoresho bibisi, epfo ikoreshwa mubikorwa bikomeye byo gukora.Fata ibikoresho byingenzi bya karbide nkurugero, ukurikije ibikoresho byatunganijwe birashobora kugabanywamo: ibyuma, ibyuma bidafite ingese, ibyuma bikozwe mucyuma, ibyuma bidafite fer, ibyuma birwanya ubushyuhe, ibyuma bikomye, nibindi. tungsten karbide, ifu ya cobalt, tantalum niobium igisubizo gikomeye, nibindi) abayikora, umurima wo kumurongo wo hasi wibanda mubikorwa byinganda, cyane cyane bikoreshwa mumodoka na moto, ibikoresho byimashini, imashini rusange, imashini, imashini zubaka nizindi nzego, ikirere, gisirikare, imashini zubuvuzi nizindi nzego nazo zitanga uburyo bwagutse bwa tekiniki hamwe nu mwanya wo guhindura ibikoresho bya karbide.

Ni ibihe bintu biranga ibikoresho byo guca karbide?

1.uburemere bukomeye: Igikoresho cya Carbide gikozwe muri karbide ifite ubukana bwinshi no gushonga (bizwi nka fase ikomeye) hamwe nicyuma gihuza ibyuma (bizwi nka binding phase) hakoreshejwe uburyo bwa powder metallurgie, ubukana bwayo ni 89 ~ 93HRA, burenze cyane ibyuma byihuta cyane , kuri 5400C, ubukana burashobora kugera kuri 82 ~ 87HRA, hamwe nubushyuhe bwicyumba cyicyumba cyihuta (83 ~ 86HRA) kimwe.

2. Kunama imbaraga no gukomera: imbaraga zo kugonda imbaraga zisanzwe zikomeye ziri murwego rwa 900 ~ 1500MPa.Iyo hejuru yibigize ibyuma bihuza icyiciro, niko imbaraga zunama.Iyo ibirimo guhuza ari bimwe, YG (WC-Co).Imbaraga zivanze zisumba YT (WC-Tic-Co) ivanze, kandi imbaraga ziragabanuka hamwe no kwiyongera kwa TiC.Amavuta akomeye ni ubwoko bwibintu byoroshye, ingaruka zabyo mubushyuhe bwicyumba ni 1/30 ~ 1/8 cya HSS.

3. Kurwanya kwambara neza.Umuvuduko wo kugabanya ibikoresho bya karbide wikubye inshuro 4 ~ 7 kurenza icyuma cyihuta, kandi ubuzima bwibikoresho buri hejuru ya 5 ~ 80.Gukora ibishushanyo, ibikoresho byo gupima, ubuzima burenze ibyuma byabigenewe ibyuma inshuro 20 ~ 150 hejuru.Irashobora guca 50HRC cyangwa ibikoresho bikomeye.
