Xov Xwm - Cov Txheej Txheem Tseem Ceeb thiab Cov Khoom ntawm Cov Hlau Kub-Dov: Los ntawm Kev Tsim Khoom mus rau Daim Ntawv Thov

Hauv kev lag luam hlau loj heev,kub-kuav hlau kaujua haujlwm ua cov khoom siv tseem ceeb, siv dav hauv cov teb xws li kev tsim kho, kev tsim khoom siv tshuab, thiab kev lag luam tsheb. Cov hlau carbon coil, nrog nws cov kev ua tau zoo heev thiab kev siv nyiaj tsim nyog, tau dhau los ua cov khoom siv tseem ceeb hauv kev ua lag luam. Kev nkag siab txog nws cov yam ntxwv tseem ceeb thiab cov khoom tsis yog tsuas yog qhov tseem ceeb rau kev txiav txim siab yuav khoom xwb tab sis kuj tseem ceeb rau kev ua kom muaj nqis ntawm cov khoom siv.

Hauv qhov xwm txheej ua haujlwm hauv Hoobkas, ib tug neeg ua haujlwm hnav lub kaus mom xiav thiab lub tsho xiav saib ntsoov lub kauj hlau kub uas raug tsa los ntawm lub crane. Nyob ib puag ncig lawv yog cov kauj hlau kub uas tau teeb tsa zoo nkauj. Cov kauj hlau loj heev thiab qhov chaw ua haujlwm zoo qhia txog kev ruaj khov thiab kev ua haujlwm ntawm cov hlau tsim thiab ua cov hlau, qhia txog qhov tseem ceeb ntawm cov kauj hlau kub ua cov khoom siv tseem ceeb hauv kev tsim khoom lag luam, thiab tseem qhia txog huab cua nruj thiab zoo thaum lub sijhawm ua haujlwm hauv Hoobkas.

ASTM A36 Hlau Chev

Kev tsim cov hlau carbon pib ntawmcov hlau carbon kaujHoobkas, qhov twg billets raug ua tiav rau hauv cov kauj ntawm cov lus qhia tshwj xeeb los ntawm cov txheej txheem dov kub siab. Piv txwv li,ASTM A36 hlau kaujyog ib qib hlau uas siv ntau tshaj plaws uas tau teev tseg los ntawm American Society for Testing and Materials (ASTM) cov qauv thiab yog qhov xav tau heev hauv kev tsim kho thiab kev tsim kho vaj tse. ASTM A36 coil muaj lub zog tso zis ntawm ≥250 MPa thiab lub zog tensile ntawm 400-550 MPa, nrog rau kev ua haujlwm zoo heev thiab kev sib txuas, ua tau raws li qhov yuav tsum tau thauj khoom thiab kev sib txuas ntawm cov qauv loj xws li choj thiab cov thav duab Hoobkas. Nws cov tshuaj lom neeg feem ntau ua rau cov ntsiab lus carbon qis dua 0.25%, ua kom muaj zog thiab tawv thaum tsis txhob muaj kev tawg ntawm cov pa roj carbon ntau dhau.

Los ntawm qhov kev xav ntawm cov txheej txheem, qhov tuab, qhov dav, thiab qhov hnyav ntawm lub kauj yog cov cim qhia tseem ceeb rau kev ntsuam xyuas kev ua tau zoo ntawm cov hlau kub dov. Cov tuab feem ntau yog txij li 1.2 txog 25.4 hli, thaum qhov dav tuaj yeem tshaj 2000 hli. Qhov hnyav ntawm lub kauj tuaj yeem hloov kho tau, feem ntau yog txij li 10 txog 30 tons. Kev tswj qhov ntev tsis yog tsuas yog cuam tshuam rau kev ua haujlwm zoo xwb tab sis kuj cuam tshuam ncaj qha rau qhov tseeb ntawm cov khoom kawg. Piv txwv li, qhov kam rau siab ntawm cov hlau kub dov siv hauv kev tsim tsheb yuav tsum tau tswj hwm nruj me ntsis hauv ± 0.05 hli kom ntseeg tau tias muaj qhov ntev sib xws ntawm cov khoom stamped.

Cov Kev Cai Ua Haujlwm ntawm Cov Hlau Kub-Kuav Los Ntawm Cov Hlau Hauv Cov Lag Luam Sib Txawv

Cov kev cai ua tau zoo rau cov hlau kub dov sib txawv ntau yam hauv txhua qhov kev lag luam. Kev lag luam tsim kho qhov tseem ceeb rau lub zog thiab kev tiv thaiv huab cua, thaum kev lag luam machining qhov tseem ceeb rau kev siv tshuab thiab qhov chaw tiav. Yog li ntawd, cov chaw tsim khoom siv hlau carbon yuav tsum hloov kho lawv cov txheej txheem tsim khoom rau cov neeg siv khoom xav tau. Piv txwv li, kev tswj hwm dov thiab txias cov txheej txheem tuaj yeem siv los ua kom zoo dua cov qauv noob, lossis cov ntsiab lus alloying tuaj yeem ntxiv los txhim kho cov khoom tshwj xeeb. Piv txwv li, rau cov kauj siv hauv cov chaw muaj av noo siab, kev ntxiv cov ntsiab lus xws li phosphorus thiab tooj liab tuaj yeem txhim kho kev tiv thaiv corrosion hauv huab cua.

Txij li cov txheej txheem tsim khoom ntawm cov chaw tsim khoom carbon steel coil mus rau qhov xav tau ntawm cov neeg siv kawg, cov yam ntxwv tseem ceeb thiab cov yam ntxwv ntawm cov hlau kub dov tau sib txuas thoob plaws hauv cov saw hlau xa khoom. Txawm hais tias yuav cov hlau coils hauv ntau lossis xaiv cov ASTM A36 coils tshwj xeeb, kev nkag siab tob txog cov khoom siv yog qhov tseem ceeb rau kev ua tiav qhov sib npaug zoo tshaj plaws ntawm kev ua tau zoo thiab tus nqi, tso lub hauv paus ruaj khov rau kev txhim kho zoo hauv ntau yam lag luam.
