Nta thiab Kev Siv Cemented Carbide

Cov yam ntxwv ntawm tungsten carbide

Tungsten carbide muaj siab hardness thiab hnav tsis kam. Kev txiav ceev ntawm cov cuab yeej carbide yog 4 mus rau 7 npaug siab dua li cov hlau ceev ceev thiab 5 mus rau 80 npaug ntawm lub neej kev pabcuam siab dua. Carbide cov khoom tuaj yeem txiav cov ntaub ntawv nyuaj txog li 50HRC. Cov ntawv yuav qhia qee qhov kev paub tseem ceeb txog cemented carbide.

Cov khoom siv ntawm tungsten carbide

Cemented carbide feem ntau yog cov hmoov me me ntawm carbides (WC, TiC) ntawm high-hardness refractory hlau. Cov khoom tseem ceeb yog hmoov metallurgical khoom sintered nyob rau hauv lub tshuab nqus tsev vacuum los yog ib tug hydrogen txo cubalt nrog cobalt (Co), npib tsib xee (Ni), thiab molybdenum (Mo) raws li cov binder.

Lub matrix ntawm cemented carbide yog tsim los ntawm ob qhov chaw: ib feem yog hardening theem, thiab lwm qhov yog cov hlau sib txuas.

Lub hardened theem yog cov carbide, xws li tungsten carbide, titanium carbide, thiab tantalum carbide. Nws hardness yog siab heev. Nws cov ntsiab lus melting yog siab dua 2000 ° C, thiab qee qhov tseem tshaj 4000 ° C. Lub hav zoov ntawm lub hardening theem txiav txim siab heev hardness thiab hnav tsis kam ntawm carbide.

Tungsten carbide WC grain loj yuav tsum tau rau cemented carbide siv cov nplej sib txawv WC raws li kev siv sib txawv.

Kab lus no feem ntau qhia peb txoj kev siv cov cemented carbide:

1. Tungsten carbide ua cov cuab yeej carbide

Carbide tej cuab yeej yog dav siv rau hlau txiav thiab machining. Fine machining alloys xws li ko taw cutter hniav thiab V-CUT riam siv ultra-fine, sub-fine, thiab nplua-grained WC. Rough-machining alloys siv nruab nrab-grain WC. Lub ntiajteb txawj nqus txiav alloys thiab hnyav-duty txiav alloys siv nruab nrab thiab ntxhib Granular WC ua raw khoom.

2. Cemented carbide rau kev ua cov cuab yeej carbide mining

Lub pob zeb muaj siab hardness thiab muaj kev cuam tshuam loj. Coarse WC tau txais yuav, thiab lub pob zeb cuam tshuam me me nrog lub nra me. Qhov nruab nrab WC yog siv los ua cov khoom siv raw.

3. Hard alloy ua rau carbide hnav-resistant qhov chaw

Thaum hais txog nws qhov hnav tsis kam, compression resistance, thiab nto tiav, WC nrog ntau qhov sib txawv yog siv los ua raw khoom, thiab nruab nrab thiab ntxhib-grained WC raw khoom yog siv los ua cov khoom tseem ceeb.

4. Hard hlau ua tungsten carbide Tuag

Cov carbide tuag muaj ob peb kaum lub sijhawm ua haujlwm ntev dua li cov pwm hlau. Carbide pwm muaj siab hardness, siab zog, corrosion kuj, high-temperature kuj, thiab me me expansion coefficient, feem ntau yog tsim los ntawm tungsten cobalt.
