Dab tsi yog Qhov Tseem Ceeb Cov Cwj Pwm Ntawm 16Mn Txias Tos Cov Hlau Yeeb

Sij hawm dhau los, ib lub npe rau cov yeeb nkab txias steel. Lub npe tam sim no: Q345B txias txias steel yeeb nkab. Cov khoom sib xws yog Q345C, Q345D, Q345E. Cov cim zoo qib ABCDE qhia tau tias tsis tas yuav kuaj tsis raug. Qhov cuam tshuam ntsuas kub yog +20 degrees 0 degrees -20 degrees 40 degrees.

16. Dab tsi yog sawv cev yog tias cov pa roj carbon ntsiab lus hauv cov hlau no yog li 0.16%. Mn tau thov cais vim tias muaj cov ntsiab lus siab ntawm manganese ntawm tsib lub ntsiab (carbon C, silicon Si, manganese Mn, phosphorus P, thiab sulfur S). Nws yog txog 1.20-1.60%.

Cov yam ntxwv tseem ceeb ntawm 16Mn txias kos cov yeeb nkab steel: kev ua tiav zoo, ua tau zoo tsis kub, kev ua haujlwm txias txias, kev ua haujlwm vuam zoo thiab ua kom tiav.

1. Cov pes tsawg leeg zoo kos xim txias hlau kav yog qhov tsis sib thooj, tonnage ntawm lub tshuab txiab txias yog qhov siab, thiab lub ntsej muag kawg ntawm lub taub hau txiav yog du thiab huv si. Txawm li cas los xij, vim yog cov khoom siv tsis zoo, lub ntsej muag kawg ntawm lub taub hau txiav feem ntau muaj qhov tshwm sim ntawm cov nqaij ploj, uas yog, qhov tsis sib luag, thiab tsis muaj cov lus hlau. Ntxiv mus, vim tias cov khoom lag luam ntawm cov khoom cuav thiab cov khoom qis me me muaj tsawg dua kev txiav, lub pob ntseg loj yuav tshwm ntawm lub taub hau thiab tw. 2. Inferior txias kos cov kav hlau tsis muaj qhov ntxaij hlau, thiab yog lub teeb liab lossis zoo ib yam li npua hlau. Muaj ob qho laj thawj vim li cas nws qhov billet yog adobe. Cov ntxuag qhov kub ntawm cov khoom cuav thiab cov khoom ua tsis tau zoo tsis yog qhov qauv, thiab lawv qhov ntsuas kub ntawm cov xim hlau yog qhov pom kev pom, yog li kev ua haujlwm ntawm dov hauv thaj chaw austenite tshwj xeeb yuav tsis ua tiav cov qauv.

3. Cov khoom siv ntawm fake txias twv cov yeeb nkab muaj ntau impurities, qhov ntom ntawm steel tsis dhau, thiab qhov loj tsis tawm ntawm kev zam lub siab, yog li nws tuaj yeem hnyav thiab kuaj xyuas tsis muaj vernier calipers.

4. Ntu ntoo khaub lig-los ntawm qhov cuav txias kos cov yeeb nkab steel yog elliptical. Qhov laj thawj yog tias txhawm rau txuag cov khoom siv, qhov yuav txo qis ntawm thawj ob kis ntawm cov yob tiav tiav loj dhau. Lub zog ntawm hom rebar zoo heev txo, thiab nws tsis yoog nrog tus duab ntawm rebar. Cov Qauv.

5. Sab saum npoo ntawm fake txias kos yeeb nkab yog yooj yim caws pliav. Muaj ob qho laj thawj: material Cov khoom siv ntawm cov ntawv tuab ntawm cov yeeb nkab tsis sib xws yog cov tsis sib xws thiab muaj ntau cov impurities. Manufacturers Cov cuab yeej tsim qis thiab qis dua cov khoom lag luam muaj cov lus qhia yooj yooj yim thiab cov cuab yeej zov thiab yooj yim lo rau hlau. Cov impurities no yuav yooj yim ua rau nti tom qab yoov.
