Qhov ceev ntawm steel phaj yog feem ntau 7.85 grams ib cubic centimeter (g / cm³), tus qauv tus nqi rau carbon steel thiab qis - alloy steel. Steel phaj ceev yog ib qho tseem ceeb ntawm lub cev khoom ntawm cov khoom, ncaj qha cuam tshuam qhov hnyav xam thiab cov qauv tsim. Cov kev ntsuam xyuas hauv qab no muab ntau qhov kev pom -dimensional:
Technical Principple: Qhov ntom yog qhov piv ntawm qhov loj rau ntim. Qhov ceev ntawm lub phaj steel nyob ntawm nws cov tshuaj muaj pes tsawg leeg (xws li cov ntsiab lus ntawm cov ntsiab lus xws li hlau, carbon, thiab manganese) thiab microstructure (xws li cov nplej loj thiab suav nrog). Cov pa roj carbon steel, vim nws cov ntsiab lus tsis tshua muaj carbon (feem ntau Tsawg dua lossis sib npaug li 2.1%), tswj qhov ceev ruaj khov ntawm 7.85 g / cm³. Stainless hlau, vim nws cov ntsiab lus alloying xws li chromium thiab npib tsib xee, muaj qhov ntom ntom dua me ntsis (7.93-8.0 g / cm³).
Daim Ntawv Thov Scenario: Qhov ntom ntom yog qhov tseem ceeb hauv engineering. Piv txwv li, qhov hnyav ntawm cov hlau phaj siv hauv cov thawv yuav tsum tau muab xam kom meej kom muaj kev nyab xeeb kev thauj mus los. Hauv cov qauv tsim, qhov ntom ntom, ua ke nrog cov tuab, tuaj yeem siv los kwv yees cov khoom thauj -cov kabmob muaj peev xwm.
Cov qauv kev lag luam: Cov qauv hauv tsev thiab thoob ntiaj teb (xws li ASTM A36 thiab GB / T 709) xav tias qhov ntom ntom ntawm 7.85 g / cm³ rau cov hlau phaj. Tshwj xeeb alloy steel daim hlau yuav tsum tau kho raws li lawv muaj pes tsawg leeg.
Piv txwv: Yog tias cov hlau phaj qhov ntev yog 1m × 2m × 10mm (0.01m), ces hnyav=ntim × ntom=1 × 2 × 0.01 × 7.85 × 1000=157kg. Hauv kev ua lag luam tiag tiag, thov nco ntsoov seb qhov ntsuas qhov ntsuas qhov ntsuas (qhov ntsuas qhov hnyav) lossis qhov hnyav tiag tiag yog siv.
Lus Cim: Qhov kub thiab txias ua haujlwm yuav ua rau muaj kev hloov pauv me ntsis ntawm qhov ntom ntom (± 0.5%), tab sis qhov no tsis tsim nyog rau feem ntau cov ntawv thov.
