Carbide saw hniav feem ntau yog siv cov cuab yeej txiav rau kev ua cov khoom ntoo. Qhov zoo ntawm carbide saw hniav yog ze ze rau qhov zoo ntawm cov khoom tiav. Kev xaiv raug thiab tsim nyog ntawm carbide saw hniav yog qhov tseem ceeb rau kev txhim kho cov khoom zoo, ua kom luv luv, thiab txo cov nqi ua haujlwm.
1. Kev xaiv ntawm carbide saw hniav
Carbide saw hniav muaj xws li ntau yam tsis xws li hom alloy cutter taub hau, cov khoom ntawm matrix, txoj kab uas hla, tus naj npawb ntawm cov hniav, thickness, hniav zoo, lub kaum sab xis, aperture, thiab lwm yam. . Thaum xaiv cov saw hniav, koj yuav tsum xaiv qhov tseeb saw hniav raws li hom, thickness, sawing ceev, sawing kev taw qhia, pub ceev, thiab sawing txoj kev dav ntawm cov khoom raug txiav.
(1) Kev xaiv cov cemented carbide hom
Feem ntau siv hom cemented carbide yog tungsten-cobalt (code YG) thiab tungsten-titanium (code YT). Vim tias tungsten-cobalt carbide muaj kev cuam tshuam zoo dua, nws tau siv dav hauv kev lag luam ntoo. Cov qauv siv feem ntau hauv kev ua ntoo yog YG8-YG15. Tus lej tom qab YG qhia qhov feem pua ntawm cov ntsiab lus cobalt. Raws li cov ntsiab lus cobalt nce, qhov cuam tshuam toughness thiab dabtsi yog khoov lub zog ntawm alloy nce, tab sis hardness thiab hnav tsis kam txo. Nws yog tsim nyog Xaiv raws li qhov xwm txheej tiag tiag.
(2) Kev xaiv ntawm matrix
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. Cov cuab yeej carbon steel muaj cov pa roj carbon ntau thiab cov thermal conductivity, tab sis nws cov tawv tawv thiab hnav tsis kam poob qis thaum raug kub ntawm 200 ° C-250 ° C. Nws muaj kev kho cua sov loj deformation, tsis zoo hardenability, thiab nws yooj yim rau tawg tom qab tempering lub sij hawm ntev. Ua cov khoom siv nyiaj txiag rau cov cuab yeej txiav xws li T8A, T10A, T12A, thiab lwm yam.
3. Muab piv nrog cov cuab yeej carbon steel, cov cuab yeej hlau alloy muaj cov cua sov zoo, hnav tsis kam thiab ua haujlwm zoo dua. Lub tshav kub-resistant deformation kub yog 300 ℃ -400 ℃, uas yog tsim rau kev tsim cov khoom zoo zoo alloy ncig saw hniav.
4. High-speed tool steel muaj zoo hardenability, muaj zog hardness thiab rigidity, thiab me ntsis tshav kub-resistant deformation. Nws yog ib qho ultra-high-strength steel nrog ruaj khov thermoplasticity thiab yog tsim rau kev tsim ultra-nyias saw hniav nrog zoo zoo.
