Kev siv cov ntaub ntawv kuj tseem ceeb heev raucov ntsia hlau tsis yog tus qauv, thiab covkev cai ntsia hlaucov ntaub ntawv uas siv tau rau hauv ntau daim ntawv thov sib txawv, xws li cov qauv kev ua tau zoo ntawm cov ntaub ntawv sib txawv, thiab lwm yam, raws lintsia hlau lag luam tam sim nomanufactur feem ntau suav nrog cov hlau carbon, hlau tsis xeb, tooj liab peb cov ntaub ntawv.
1. Vim li cas ho xaiv cov hlau carbon, hlau tsis xeb, tooj liab?
Cov hlau carbon: Peb paub qhov txawv ntawm cov hlau carbon qis, cov hlau carbon nruab nrab thiab cov hlau carbon siab, thiab cov hlau alloy los ntawm qhov ntau ntawm cov carbon hauv cov hlau carbon.
(1) Cov hlau carbon tsawg C% ≤0.25% feem ntau hu ua A3 hlau hauv Suav teb. Cov teb chaws txawv teb chaws feem ntau hu ua 1008, 1015, 1018, 1022, thiab lwm yam. Nws feem ntau yog siv rau cov khoom tsis muaj qhov yuav tsum tau ua kom tawv xws li 4.8 qib bolts, 4 qib txiv ntoo thiabcov ntsia hlau me me(Ceeb Toom: Cov khoom siv 1022 feem ntau yog siv rau cov ntsia hlau laum.)
(2) Cov hlau carbon nruab nrab 0.25%
(3) Cov hlau carbon siab C%> 0.45%. Tam sim no, nws yeej tsis siv hauv kev ua lag luam
(4) Cov hlau sib xyaw: ntxiv cov khoom sib xyaw rau cov hlau carbon ib txwm kom nce qee cov khoom tshwj xeeb ntawm cov hlau: xws li 35, 40 chromium molybdenum, SCM435, 10B38. Panvo screws feem ntau siv SCM435 chrome alloy steel, thiab cov khoom tseem ceeb yog C, Si, Mn, P, S, Cr, thiab Mo.
Cov hlau carbon ntsia hlaumuaj lub zog thiab qhov nyuaj siab, tiv taus kev hnav zoo, muaj zog plasticity, thiab tus nqi tsim khoom qis. Cov yam ntxwv no ua rau cov hlau carbon yog cov khoom siv zoo tshaj plaws rau kev tsim cov khoom txheem.
Hlau tsis xeb: qib kev ua tau zoo: 45, 50, 60, 70, 80
Cov khoom tseem ceeb yog austenite (18% Cr, 8% Ni), uas muaj kev tiv taus cua sov zoo, kev tiv taus corrosion zoo thiab weldability zoo. A1, A2, A4 martensitic thiab 13% Cr muaj kev tiv taus corrosion tsis zoo, lub zog siab thiab kev tiv taus hnav zoo. C1, C2, C4 ferritic stainless hlau. 18% Cr upsetting zoo dua, thiab kev tiv taus corrosion muaj zog dua li martensite. Tam sim no, cov ntaub ntawv xa tuaj hauv khw feem ntau yog cov khoom Nyiv. Raws li qib, nws feem ntau muab faib ua SUS302, SUS304, thiab SUS316.
Cov ntsia hlau tsis xebmuaj kev tiv thaiv corrosion zoo heev, tuaj yeem khaws cia rau hauv qhov zoo rau lub sijhawm ntev hauv qhov chaw nyuaj, thiab tsis yooj yim rau xeb. Tsis tas li ntawd, cov hlau tsis xeb muaj cov yam ntxwv ntawm lub zog siab, zoo nkauj zoo nkauj, thiab yooj yim ua.
Tooj Liab: Cov khoom siv feem ntau yog tooj dag ... Zinc-tooj liab alloy. H62, H65 thiab H68 tooj liab feem ntau yog siv ua cov khoom txheem hauv kev ua lag luam.
Tooj liab ntsia hlaumuaj kev ua hluav taws xob zoo, kev ua thermal, kev tiv thaiv corrosion thiab cov khoom ua tiav, thiab tuaj yeem welded thiab brazed. Cov khoom no ua rau tooj liab muaj txiaj ntsig zoo hauv kev xa hluav taws xob, motors
2 Qhov txawv ntawm cov hlau tsis xeb thiab cov hlau carbon yog dab tsi?
Cov hlau tsis xeb thiab cov hlau carbon kuj yog cov khoom siv hlau, thiab ntau tus neeg tsis paub tias qhov txawv ntawm cov hlau tsis xeb thiab cov hlau carbon yuav yog dab tsi.
Qhov txawv ntawm cov hlau tsis xeb thiab cov hlau carbon yog dab tsi? Nyob ntawm lub hom phiaj thiab kev ua tau zoo, feem ntau muaj cov qhov sib txawv hauv qab no:
(1) Cov hlau tsis xeb muaj cov thermal conductivity tsis zoo thiab elongation qis vim nws cov thermal conductivity tsis zoo thiab elongation, yog li lub zog deformation xav tau loj;
(2) Piv nrog cov hlau carbon, cov hlau stainless hlau muaj qhov muaj zog rov qab los thaum khoov;
(3) Piv nrog cov hlau carbon, vim tias qhov ntev ntawm cov hlau stainless hlau phaj qis, lub kaum sab xis R ntawm qhov workpiece yuav tsum loj dua li ntawm cov hlau carbon thaum khoov, txwv tsis pub muaj qhov ua tau ntawm kev tawg;
(4) Vim yog qhov nyuaj ntawm cov hlau stainless hlau phaj thiab qhov cuam tshuam tseem ceeb ntawm kev ua haujlwm txias hardening, thaum xaiv cov cuab yeej khoov compression, cov cuab yeej hlau nrog kev kho cua sov hardness ntawm ntau dua 60HRC yuav tsum tau xaiv, thiab nws qhov roughness ntawm qhov chaw yuav tsum tau ua.
Hauv Yuhuang,Tuam Tshoj chaw tsim khoom ntsia hlaupeb paub tiaslub hau zoocov khoom siv raw yog lub hauv paus rau kev tsim cov khoom zoo heev. Yog li ntawd, txhuantsia hlauyog ua los ntawm cov hlau alloy siab, hlau tsis xeb thiab lwm yam khoom siv siab heev uas tau raug tshuaj xyuas kom zoo kom ntseeg tau tias nws tsis tsuas yog muaj peev xwm thauj khoom muaj zog thiab tiv taus corrosion, tab sis kuj tswj hwm kev ua haujlwm ruaj khov thiab txhim khu kev qha hauv cov chaw ib puag ncig hnyav. Xaiv Yuhuang screws, koj xaiv qhov kev lees paub zoo tshaj plaws.
