A36 steel puas tuaj yeem khoov?

Feem ntau cov dabtsi yog khoov thiab dov cov cav tov tau ntsuas siv "tus qauv" ntawm cov hlau me me A36 lossis 1018nrog yield zog nyob ib ncig ntawm 36,000 psi. Nco ntsoov tias cov no yog cov khoom raug lossis txawm tias yam tsawg kawg nkaus.

Steel Phaj Rolling thiab khoov ntawm Siab zog Steels

Thaum ua steel phaj dov thiab khoov ntawm lub zog siab dua steels, koj yuav muaj ob lub ntsiab lus tseem ceeb:

1. Lub tonnage/muaj peev xwm ntawm lub tshuab
2. Lub caij nplooj ntoos hlav rov qab ntawm cov khoom tom qab lub siab tso tawm

Lub tonnage yog ncaj ncaj hauv kev faib ua feem nrog lub zog tawm los. Yog li yog tias lub zog tawm los ua ob npaug, yog li lub tonnage yuav tsum tau khoov nws. Feem ntau cov dabtsi yog khoov thiab dov cov cav tov tau ntsuas siv "tus qauv" ntawm cov hlau me me A36 lossis 1018 nrog lub zog tawm los ntawm 36,000 psi.

Nov yog qee cov qhab nia uas tau teev tseg rau kev khoov thiab dov:

Qib TYPICAL Yield zog Tonnage MultiplierGrade TYPICAL Yield zog Tonnage Multiplier
A572Gr .50 50,000psi x 1.38
A588 Corten 50,000psi x 1.38
A516Gr .70 70,000 psi x 1.94
AR 400 100,000psi x 2.78

Nco ntsoov tias cov no yog cov khoom raug lossis txawm tias yam tsawg kawg nkaus.

Koj yuav tsum tau saib ntawm MTR (Cov Ntaub Ntawv Qhia Txog Cov Khoom Siv) los ntawm cov khoom tsim los xyuas qhov tseeb ntawm cov hlau koj tab tom sim khoov.

Lub caij nplooj ntoos hlav rov qab ntawm cov khoom siv yog ib qho qauv nyuaj, tab sis feem ntau:

1. Qhov siab dua lub zog tawm los, qhov ntau ntawm cov khoom siv rov qab
2. Qhov loj dua lub vojvoog tsim, ntau lub caij nplooj ntoos hlav rov qab lub kaum sab xis

Piv txwv li, thaum koj khoov ¼ "phaj mus rau ¼" vojvoog 90 degrees,
A36 yuav springback tsuas yog 0.25 degrees.
Gr50 yuav springback tseem tsuas yog 0.35 degrees.

Tab sis yog hais tias lub vojvoog loj dua, hais 2", ces
A36 yuav springback 2.58 degrees.
Gr50 yuav springback 3.58 degrees.

cov lus hauv qab no sib xyaw ntawm cov txiaj ntsig thiab lub zog tensile rau ob yam khoom nram qab no
