C1.064 GB3092 Kub-dip Galvanized Steel Pipes

Cov mis rau xam qhov yield point yog:
Hauv cov qauv: Fs--yield force (constant) thaum lub sij hawm tensile txheej txheem ntawm tus qauv, N (Newton) Yog li-- thawj qhov chaw hla ntu ntawm tus qauv, mm2.
Elongation tom qab so (σ)
Hauv kev sim tensile, qhov feem pua ​​​​ntawm qhov ntev ntawm qhov ntsuas qhov ntev ntawm cov qauv tom qab nws tawg mus rau qhov ntsuas qhov ntev yog hu ua elongation. Qhia los ntawm σ, chav tsev yog %. Cov mis laij lej yog:
Hauv cov qauv: L1-- qhov ntsuas qhov ntev ntawm cov qauv tom qab tawg, mm; L0-- qhov ntsuas qhov ntev ntawm tus qauv, mm.
Thaj chaw shrinkage (ψ)
Hauv kev sim tensile, qhov feem pua ​​​​ntawm qhov kev txo qis tshaj plaws nyob rau hauv cheeb tsam cross-sectional ntawm qhov txo txoj kab uas hla tom qab cov qauv raug tawg thiab qhov chaw seem ntawm qhov qub yog hu ua qhov txo ntawm cheeb tsam. Qhia los ntawm ψ, chav tsev yog %. Muab xam raws li nram no:
Hauv cov qauv: S0-- thawj qhov chaw hla ntu ntawm tus qauv, mm2; S1-- thaj tsam tsawg kawg ntawm ntu ntawm txoj kab uas hla txo tom qab tus qauv tawg, mm2.
Hardness index
Lub peev xwm ntawm cov khoom siv hlau los tiv thaiv qhov indentation ntawm qhov chaw los ntawm cov khoom tawv yog hu ua hardness. Raws li cov kev sim sib txawv thiab daim ntawv thov, qhov nyuaj tuaj yeem muab faib ua Brinell hardness, Rockwell hardness, Vickers hardness, Shore hardness, microhardness thiab kub hardness. Muaj peb feem ntau siv hardnesses rau cov kav dej: Brinell, Rockwell, thiab Vickers hardness.
A. Brinell hardness (HB)
Siv lub pob steel lossis carbide pob ntawm ib txoj kab uas hla los nias rau hauv cov qauv saum npoo nrog lub zog ntsuas (F). Tom qab lub sijhawm tuav tau teev tseg, tshem tawm qhov kev sim quab yuam thiab ntsuas qhov indentation txoj kab uas hla ntawm tus qauv nto. (L) Brinell hardness tus nqi yog cov quotient tau los ntawm kev faib cov kev xeem quab yuam los ntawm indentation spherical nto cheeb tsam. Qhia hauv HBS (steel ball), chav tsev yog N / mm2 (MPa).

FAQ

Q: Koj lub tuam txhab ua haujlwm li cas?

A: Peb lub tuam txhab yog cov chaw tsim khoom, peb tsuas yog tsim cov ntawv hlau stainless, stainless hlau kauj, stainless hlau yeeb nkab, stainless hlau tuav thiab lwm yam.

Q: Koj tuaj yeem ua kom koj qhov zoo?

1.Peb tuaj yeem muab daim ntawv pov thawj zoo rau koj.
