Carbide saw agụba na-ejikarị egbutu ngwaọrụ maka osisi ngwaahịa nhazi. Ogo nke mkpụrụ osisi carbide nwere njikọ chiri anya na ịdị mma nke ngwaahịa emebere. Nhọrọ ziri ezi na ezi uche dị na ya nke mkpụrụ osisi carbide dị oke mkpa iji melite ogo ngwaahịa, na-ebelata usoro nhazi, na ibelata ọnụ ahịa nhazi.
1. Nhọrọ nke carbide saw agụba
Carbide hụrụ agụba na-agụnye multiple parameters dị ka ụdị alloy cutter isi, ihe onwunwe nke matriks, dayameta, ọnụ ọgụgụ nke ezé, ọkpụrụkpụ, nha nha udi, n'akuku, oghere, wdg Ndị a parameters ikpebi nhazi ike na ịcha arụmọrụ nke saw agụba. . Mgbe ị na-ahọrọ agụba, ị ga-ahọrọ nke ọma saw agụba dị ka ụdị, ọkpụrụkpụ, sawing ọsọ, sawing direction, nri ọsọ, na sawing ụzọ obosara nke ihe a na-ebipụ.
(1) Nhọrọ nke ụdị carbide cimented
Ụdị carbide ciment a na-ejikarị eme ihe bụ tungsten-cobalt (koodu YG) na tungsten-titanium (koodu YT). N'ihi na tungsten-cobalt carbide nwere mmetụta dị mma nke ukwuu, a na-ejikarị ya eme ihe na ụlọ ọrụ nhazi osisi. Ụdị a na-ejikarị eme ihe na nhazi osisi bụ YG8-YG15. Ọnụọgụ gachara YG na-egosi pasentị ọdịnaya cobalt. Ka ọdịnaya cobalt na-abawanye, mmetụta siri ike na ike na-ehulata nke alloy na-abawanye, mana ike na iyi mgbochi na-ebelata. Ọ dị mkpa ka Họrọ dabere na ọnọdụ n'ezie.
(2) Nhọrọ nke matriks
1. 65Mn spring steel has good elasticity and plasticity, economical material, good heat treatment hardenability, low heating temperature and easy deformation, so it can be used for saw blades with low cutting requirements.
2. Carbon ngwá ọrụ ígwè nwere elu carbon na elu thermal conductivity, ma ya ekweghị ekwe na eyi na-eguzogide dara sharply mgbe ekpughere okpomọkụ nke 200C-250C. Ọ nwere nnukwu nrụrụ ọgwụgwọ okpomọkụ, ike siri ike na-adịghị mma, ọ na-enwekwa ike ịgbawa mgbe ogologo oge iwe gasịrị. Mee ihe eji echekwa ego maka ịkpụ ngwaọrụ dịka T8A, T10A, T12A, wdg.
3. N'iji ya tụnyere carbon ngwá ọrụ ígwè, alloy ngwá ọrụ ígwè nwere ezigbo okpomọkụ na-eguzogide, eyi iguzogide na mma nhazi arụmọrụ. The okpomọkụ na-eguzogide deformation okpomọkụ bụ 300 ℃-400 ℃, nke bụ adabara n'ichepụta elu-edu alloy okirikiri ikwo agụba.
4. Ngwongwo ngwa ngwa ngwa ngwa nwere ezigbo ike ike, ike siri ike na siri ike, na obere nrụrụ na-eguzogide okpomọkụ. Ọ bụ ígwè siri ike dị elu nke nwere thermoplasticity kwụsiri ike ma dabara adaba maka imepụta ihe ọkụkụ dị mkpa dị mkpa nke nwere ezigbo mma.
