Thaum lub sijhawm nug cov neeg siv khoom, peb yuav hais tus nqi ntawm ib kilogram，Qee cov neeg siv khoom tsis meej pem, vim lawv tsis ua’t paub qhov hnyav ntawm cemented carbide round bar, yog li ntawd lawv tsis paub meej txog tus nqi ib zaug. Tam sim no zzbetter qhia koj cov qauv kev suav ntawm cov khoom carbide puag ncig bar:

Muab: G=π×（Diameter/2）²×Ntev×Qhov ntom÷10⁶=    KG

Q: Qhov hnyav ntawm YG10X yog dab tsiΦ10mm * 330mm round bar?

 Cia peb suav ua ke:

G=3.14×(10.4/2)2×330×14.5÷1000000=0.407KG

Nco ntsoov：Peb feem ntau xa mus rau lubΦ10 blanks uaΦ10.3-Φ10.4 (ibtiav carbide pas nrig yog Φ10 thiab yuav tsum tau av). Peb feem ntau cia lawv mus331 rau 333 ntev. Yog li siv cov ntaub ntawv saum toj no los nqa.)

Qee tus neeg tsis paub ntau txog qhov ntom ntawm cemented carbide qib, yog liZhuzhou zoo tungsten carbide Co., Ltdpaub tias cov qib ntawm feem ntau siv cemented carbide puag ncig tuav tau teev tseg hauv qab no:

Qhov ntawd puas nkag siab?

muaj tswv lub laij lej txoj kev ntawm lub saum toj no puag ncig bar, lub xam txoj kev ntawm lubtungsten carbide tube yog qhov yooj yim dua, Tam sim no zzbetter qhia koj cov qauv kev suav ntawm cov khoom carbide round tube:

(Radius ntawm lub voj voog sab nrauv * vojvoog ntawm lub voj voog sab nrauv * 3.14 * ntev * ceev / 10⁶= qhov hnyav ntawm lub voj voog sab nraud)—(Lub vojvoog ntawm lub voj voog sab hauv * lub voj voog sab hauv * 3.14 * ntev * ntom / 10⁶= luj ntawm puab lub voj voog) = carbide raj luj

Piv txwv li

Q: Qhov hnyav ntawm YG10X yog dab tsiΦ10*Φ8 * 330 carbide raj

Cia peb suav ua ke:

G=5.2*5.2*3.14*330.5*14.5/1000000—3.9*3.9*3.14*330.5*14.5/1000000=0.178kg

Cov saum toj no yog cov txheej txheem kev suav ntawm lub round bar uas zzbetter paub nrog koj hnub no, kuv vam tias nws yuav pab tau! Koj puas tau kawm?
