Cov Khoom Taw Qhia thiab Siv
Cov Khoom Siv Hlau G31 yog cov pa roj carbon hlau cemented carbide yog ib hom cov khoom siv hluav taws xob ua tau los ntawm cov khoom siv hluav taws xob nyuaj thiab sib txuas ua ke los ntawm cov txheej txheem me me me me.
Cemented carbide muaj cov yam ntxwv zoo heev xws li hnav tsis zoo, thiab cov khoom siv hluav taws xob zoo dua, thiab nws tseem muaj lub hardness nyob rau 1000 degree.
Cemented carbide yog dav siv raws li kev txiav cov khoom, cov hlau, cov hlau thiab cov hlau thiab lwm yam hlau thiab lwm yam khoom siv nyuaj-rau-tshuab. Cemented carbide muaj siab tawv, lub zog, siv cov cuab yeej, siv me me thiab hnav thiab lwm yam kev tsim khoom lag luam, nrog rau kev tsim cov khoom siv hauv qab. Nrog rau kev loj hlob ntawm cov lag luam hauv av, qhov kev thov ntawm kev ua haujlwm carbide kev ua haujlwm carbide ntau zuj zus. Thiab yav tom ntej, kev tsim cov tshuab hluav taws kub siab thiab cov kev kawm ntawm kev tsim kho ntawm cov khoom siv carbide kom zoo nkauj thiab cov ntsiab lus zoo.

Kev Kho Cua Sov
Lub tshav kub kho txoj kev HSS yog peb qhov kev ua haujlwm ntawm quenching, Tempering thiab annealing. Quenching yog kom tau lub hardness siab thiab lub zog siab, kev kub siab yog los txhim kho kev nruj thiab cov yas, anealing yog los tshem tawm sab hauv kev ntxhov siab thiab txhim kho kev ua haujlwm sab hauv. Cov HSS HSS yuav tsum muaj kev kho cua sov sib txawv los ua kom lawv ua tiav zoo.
Kev kho vaj kub ceev steel tshav kub kho kom sov muaj xws li cov txheej txheem xws li anealing, quenching, tempering thiab lwm yam. Cov kauj ruam tshwj xeeb yog: anealing kub feem ntau yog nruab nrab ntawm860 degrees Celsius rau 880 degrees Celsius.
Thawj Preheat thaum 800 txog 850 degrees Celsius (yog li tsis tau ua rau muaj kev kub ntxhov loj rau lub 1220 txog 1250 degrees Celsius, tom qab cov roj txias. Tom qab quenching vim hais tias sab hauv lub koom haum kuj tseem khaws ib feem (txog 30%) ntawm cov khoom seem tsis hloov mus rau hauv martite, cuam tshuam rau kev ua haujlwm ntawm cov hlau ceev.
