Cov khoom tseem ceeb ntawm cemented carbide yob

Cov khoom tseem ceeb ntawmtungsten carbideyuav tsum tau txiav txim siab hauv kev xaivtungsten carbide yobyog raws li nram no:
Resistance rau thermal cracking
Feem ntau rau cov rolls ntxhib rau lub zog, tiv thaiv thermal cracking raws li qhov tseem ceeb;me me 20-yob zeb ua hauj lwm yob hnyav li ntawm 100 grams, thaum lub luj ntawm cov kev txhawb nqa yob rau dav phaj mills tau tshaj 200 tons.Kev xaiv cov yob ua ntej raws li cov kev xav tau ntawm lub zog ntawm cov zeb ntawm cov yob, xaiv kom muaj kev nyab xeeb nqa cov khoom tseem ceeb (ntau qib ntawm cam khwb cia hlau, cam khwb cia hlau lossis forged steel, thiab lwm yam).

Hardness
Thiab ua tiav yob ceev yog siab dua, dov cov khoom kawg kom muaj qhov zoo ntawm qhov chaw, rau nws rau hardness, hnav tsis kam, thiab lwm yam raws li cov kev cai tseem ceeb.Tom qab ntawd xav txog cov yob yuav tsum tau siv thaum hnav tsis kam.Vim hais tias kev hnav mechanism ntawm yob yog qhov nyuaj heev, nrog rau cov kev ntxhov siab ntawm cov neeg kho tshuab, cov nyhuv thermal ntawm dov, txias, tshuaj lom neeg cov nyhuv ntawm lubricating nruab nrab thiab lwm yam teebmeem, tsis muaj kev ntsuam xyuas ntawm cov yob hnav tsis kam ntawm kev sib koom ua ke. qhov ntsuas.Txij li thaum lub hardness yog ib qho yooj yim los ntsuas thiab muaj peev xwm cuam tshuam qhov hnav tsis kam nyob rau hauv tej yam kev mob, lub radial hardness nkhaus feem ntau yog siv los kwv yees qhov hnav tsis kam Performance index ntawm yob.
Kev cuam tshuam tsis kam
Tsis tas li ntawd, muaj qee qhov tshwj xeeb uas yuav tsum tau ua rau cov yob, xws li lub zog loj, cov yob yuav tsum muaj qhov muaj zog tom rau hauv lub peev xwm, tiv taus ntau dua;

Ua kom du
Thaum dov nyias cov khoom tshwj xeeb, rigidity, uniformity ntawm cov ntaub so ntswg, kev ua kom raug thiab nto tiav ntawm cov yob yog qhov yuav tsum tau nruj dua;

Txiav kev ua tau zoo
Thaum dov qhov nyuaj ntawm ntu, kuj xav txog kev txiav cov txheej txheem ua haujlwm ntawm lub yob lub cev.
Thaum xaiv cov yob, qee qhov kev ua tau zoo ntawm cov yob feem ntau tsis sib haum, yob yuav thiab tu cov nqi yog kim heev, yog li cov txheej txheem thiab kev lag luam zoo thiab qhov tsis zoo yuav tsum tau hnyav hnyav los txiav txim siab seb yuav siv cam khwb cia lossis forged, alloy lossis tsis- alloy, ib qho khoom siv lossis cov khoom sib xyaw.
