1. Kev Taw Qhia Txog Kev Txhawb Nqa Hlau
Kev txhawb nqa hlau yog ib qho khoom siv hlau uas siv dav dav, feem ntau yog siv los txhawb thiab txhim kho cov tsev, cov tshuab loj thiab cov khoom siv, thiab cov qauv engineering. Nws tau siv dav hauv kev tsim kho, tshuab, hluav taws xob, kev lag luam tshuaj lom neeg, roj av, aerospace, thiab lwm yam.
2. Rooj txhawb nqa hlau loj
Cov hauv qab no yog cov lus qhia loj ntawm cov hlau txhawb nqa, uas muaj cov qhov loj me ntawm cov hlau txhawb nqa, nrog rau qhov siv tau thiab cov yam ntxwv tseem ceeb.
Cov Lus Qhia Tshwj Xeeb (chav tsev: mm) Ntev (L) Txoj kab uas hla (D) Phab ntsa tuab (S) Scope ntawm daim ntawv thov Cov yam ntxwv tseem ceeb
Ф8 1000 8 0.8 Cov tsev, cov choj, thiab lwm yam. Kev ua haujlwm siab, lub zog zoo heev, tsim rau ntau lub sijhawm
Ф10 1500 10 1 Cov tshuab, khoom siv, thiab lwm yam. Muaj zog heev, tiv taus corrosion zoo, tsim nyog rau marine, tshuaj lom neeg thiab lwm yam ib puag ncig
Ф12 2000 12 1.2 Roj av, roj av ntuj, thiab lwm yam. Hnav-resistant, corrosion-resistant, lub neej ntev, haum rau ntau qhov chaw nyuaj
Ф16 2500 16 1.5 Lub zog hluav taws xob, aerospace, thiab lwm yam. Muaj peev xwm nqa tau zoo, qauv me me, yooj yim rau kev teeb tsa
Ф20 3000 20 2 Tshuaj lom neeg, tshuaj, thiab lwm yam. Kev tiv thaiv cua sov zoo, kev tiv thaiv corrosion zoo, tsim nyog rau qhov kub thiab txias thiab qhov chaw siab
Ф25 3500 25 2.5 Kev tiv thaiv ib puag ncig, khoom noj, thiab lwm yam. Kev nyab xeeb thiab kev tu cev, tsim nyog rau cov sijhawm uas muaj kev xav tau ib puag ncig siab
3. Cov kev ceev faj rau kev yuav cov hlau txhawb nqa
Thaum yuav cov khoom siv steel, cov hauv qab no yuav tsum tau xav txog:
1. Cov hlau txhawb nqa uas muaj cov lus qhia tsim nyog yuav tsum tau yuav raws li qhov chaw siv thiab qhov yuav tsum tau thauj khoom.
2. Yuav tsum xaiv cov hlau txhawb nqa uas cov chaw tsim khoom ib txwm tsim los kom ntseeg tau tias cov khoom zoo.
3. Nws yog ib qho tsim nyog yuav tsum tau them sai sai seb qhov ntev, txoj kab uas hla, phab ntsa tuab thiab lwm yam kev ntsuas ntawm cov hlau txhawb nqa puas ua tau raws li qhov yuav tsum tau ua.
4. Cov ntaub ntawv tsim nyog xws li Q235B, Q345B, thiab lwm yam yuav tsum tau xaiv rau ntau lub hom phiaj thiab ib puag ncig sib txawv.
Hauv ntej, ua ib qho tseem ceeb ntawm cov qauv tsim, qhov zoo thiab cov lus qhia ntawm cov hlau txhawb nqa yog qhov tseem ceeb rau kev ua haujlwm thiab kev nyab xeeb ntawm qhov project. Cov lus qhia saum toj no thiab cov lus ceeb toom yuav khoom yog rau kev siv xwb, thiab kuv vam tias lawv tuaj yeem pab cov neeg siv yuav thiab siv cov hlau txhawb nqa.
