Ama-Carbide saw blades asetshenziswa kakhulu amathuluzi okusika ukucubungula umkhiqizo wezinkuni. Izinga le-carbide saw blades lihlobene eduze nekhwalithi yemikhiqizo ecutshungulwayo. Ukukhethwa okulungile nokunengqondo kwama-saha ama-carbide kubaluleke kakhulu ekuthuthukiseni ikhwalithi yomkhiqizo, ukunciphisa imijikelezo yokucubungula, nokunciphisa izindleko zokucubungula.
1. Ukukhethwa kwama-saha ama-carbide
I-Carbide saw blades ihlanganisa amapharamitha amaningi njengohlobo lwekhanda lokusika ingxubevange, impahla ye-matrix, ububanzi, inombolo yamazinyo, ukujiya, ukuma kwezinyo, i-engeli, indawo yokuvula, njll. Le mingcele inquma ikhono lokucubungula nokusebenza kokusika kwe-saha blade. . Lapho ukhetha i-saw blade, kufanele ukhethe i-saw blade efanele ngokusho kohlobo, ukujiya, isivinini sokusaha, isiqondiso sokusaha, isivinini sokudla, nobubanzi bendlela yokusaha yezinto ezisikwayo.
(1) Ukukhethwa kwezinhlobo ze-carbide ezinosimende
Izinhlobo ezivame ukusetshenziswa ze-carbide enosimende i-tungsten-cobalt (ikhodi YG) ne-tungsten-titanium (ikhodi YT). Ngenxa yokuthi i-tungsten-cobalt carbide inokumelana nomthelela ongcono, isetshenziswa kabanzi embonini yokucubungula izinkuni. Amamodeli asetshenziswa kakhulu ekwenziweni kwezinkuni yi-YG8-YG15. Inombolo engemva kwe-YG ibonisa iphesenti lokuqukethwe kwe-cobalt. Njengoba okuqukethwe kwe-cobalt kukhula, ukuqina komthelela namandla okugoba we-alloy ayanda, kodwa ubulukhuni nokumelana nokugqoka kuncipha. Kuyadingeka Khetha ngokuvumelana nesimo sangempela.
(2) Ukukhethwa kwe-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. Insimbi yamathuluzi ekhabhoni iqukethe ikhabhoni ephezulu kanye ne-thermal conductivity ephezulu, kodwa ukuqina kwayo nokumelana nokuguga kwehla kakhulu lapho ichayeke kumazinga okushisa angu-200°C-250°C. Inokuguqulwa okukhulu kokwelashwa kokushisa, ukungaqini kahle, futhi ijwayele ukuqhekeka ngemva kwesikhathi eside sokushisa. Yenza izinto ezongayo zamathuluzi okusika afana ne-T8A, T10A, T12A, njll.
3. Uma kuqhathaniswa nensimbi yensimbi ye-carbon, insimbi yensimbi ye-alloy inokumelana nokushisa okuhle, ukumelana nokugqoka nokusebenza okungcono kokucubungula. Izinga lokushisa elikwazi ukumelana nokushisa lingu-300℃-400℃, elilungele ukukhiqiza ama-saha ayindilinga ayindilinga yekhwalithi ephezulu.
4. Insimbi yamathuluzi esivinini esikhulu inokuqina okuhle, ubulukhuni obuqinile nokuqina, kanye nokuguqulwa okuncane okungamelana nokushisa. Insimbi enamandla amakhulu kakhulu ene-thermoplasticity ezinzile futhi ifanele ukukhiqiza ama-saha ama-ultra-thin blades anekhwalithi enhle.
