Tsav ncej piav qhia
Nov 06, 2024| Cov xwm txheej ua haujlwm
Cov ncej tsav yog raug hloov cov kev ntxhov siab xws li torsion, shear, nro, compression, thiab kev cuam tshuam, uas tuaj yeem ua rau torsional thiab dabtsi yog khoov vibrations ntawm tus tsav ncej, ua rau muaj kev ntxhov siab ntxiv; Kev faib tawm tsis sib xws; Muaj zawv zawg kev sib txhuam ntawm tus tsav ncej caj dab thiab cov kabmob.
kev ua tau zoo
Cov hom tsis ua haujlwm tseem ceeb ntawm cov ncej tsav yog qaug zog tawg thiab hnyav hnyav ntawm lub caj dab caj dab. Yog li, cov khoom siv yuav tsum muaj lub zog siab, qee qhov cuam tshuam toughness, txaus khoov thiab torsional qaug zog thiab nruj, thiab cov ntawv xov xwm saum npoo yuav tsum muaj siab hardness thiab hnav tsis kam.
Tsav ncej khoom
Forged steel tsav ncej: zoo nruab nrab carbon steel thiab nruab nrab carbon alloy steel, xws li 40, 45, 35Mn2, 40Cr, 45Cr, 35CrMo steel, thiab lwm yam;
Kev xaiv khoom
Cov khoom no yog nruab nrab carbon alloy steel, uas yog raug rau quenching thiab tempering (los yog normalizing) tshav kub kev kho mob los txhim kho nws cov kev ua tau zoo. Nyob rau hauv xyoo tas los no, ib hom hlau tshiab, uas yog alloy quenched thiab tempered steel, tau dav siv nyob rau hauv high-power engine. Cov hlau no tau ua kom zoo dua los ntawm kev ntxiv cov ntsiab lus alloying xws li Si, Cu, thiab Ti kom ntxiv dag zog rau cov matrix thiab txhim kho lub zog ntawm cov hlau.
