Kev Ceeb Toom Rau Kev Siv Cemented Carbide (Tungsten Steel)

1. Lub xeev saum npoo ntawm tungsten steel muaj kev cuam tshuam zoo rau nws lub zog khoov. Nyob rau hauv tus txheej txheem ntawm kev tsim cov cuab yeej tungsten steel, ntau yam kab nrib pleb ntawm qhov chaw yuav tsum tau tiv thaiv, txwv tsis pub lub zog khoov ntawm tungsten steel yuav cuam tshuam zoo heev.
2. Lub brittleness ntawm tungsten hlau yog siab heev thiab tsis muaj dab tsi ua rau kub. Nyob rau hauv chav tsev kub, qhov cuam tshuam ntawm hardened steel yog 1-2 zaus ntau dua li ntawm cov hlau tungsten. Yog li ntawd, kev cuam tshuam ntawm tungsten steel tsis raug tso cai thaum ntxig thiab vuam tungsten hlau. Tsis txhob ua rau lawv sib tsoo lossis raug cuam tshuam los ntawm ib leeg thaum thauj.
3. Nws yog ib qho tseem ceeb heev kom nkag siab txog cov kab nthuav dav coefficient ntawm tungsten steel. Lub linear expansion coefficient ntawm tungsten steel yog ntau tshaj li ob zaug ntawm high-speed steel. Thaum tungsten steel thiab high-speed steel yog welded, vim qhov sib txawv ntawm linear expansion coefficient ntawm tungsten steel thiab high-speed steel, thaum cov pwm welded txias, qhov kev ntxhov siab ntawm cov txheej sab hauv thiab sab nrauv txawv, thiab sab hauv tensile. kev ntxhov siab yog tsim rau ntawm qhov chaw. Tom qab vuam, kev ntsuas yuav tsum tau coj los daws qhov kev ntxhov siab, txwv tsis pub cov tungsten steel yuav muaj cov kab nrib pleb lossis desoldering.
