1. Lub tshuab microalloying tau txhim kho SSAW yeeb nkab zoo li cas?
Qhov sib ntxiv ntawm me me ntawmniobium (Nb), vanadium (V), thiab titanium (Ti)pab txhim kho cov qauv ntawm cov nplej, nce qhov kub thiab txias, thiab txhim kho lub zog thiab tawv tsis muaj qhov cuam tshuam rau weldability-4.
2. Lub luag haujlwm ntawm "Thermo-Mechanical Controlled Processing (TMCP)" yog dab tsi?
TMCP, suav nrog kev tswj cov dov thiab txias, tso cai rau kev tsim cov siab - lub zog steel phaj rau SSAW kav nrog microstructures zoo liacicular ferrite, yielding siab zog thiab toughness tsis tas yuav kim quenching thiab tempering kub kho-4.
3. Dab tsi yog qhov feem ntau ua rau tsis ua hauj lwm hauv SSAW kav siv rau roj thiab roj?
Kev txheeb cais qhia tau tiasteeb meem phaj zoothiabweld tsis xws luagyog qhov ua rau cov yeeb nkab tsis ua haujlwm, suav txog li 60% ntawm 不合格钢管 (tsis yog-cov kav dej tsis sib haum)-2.
4. Dab tsi yog qhov teeb meem ntawm lub phaj zoo?
Lub ntsiab phaj zoo teeb meem ua rau tsis lees paub yogtsis muaj zog / toughness(tsawg Charpy cuam tshuam lub zog),Ua tsis tiav Kev Ntsuas Tear Tear Tests (DWTT), thiabcorrosion / xeb-2.
5. Yuav ua li cas zoo stability ntawm domestic SSAW yeeb nkab phaj piv rau txawv teb chaws?
Thaum lub tsev X80 SSAW cov yeeb nkab tuaj yeem phim cov qib txawv teb chaws hauv qhov nruab nrab qhov muaj zog, lawv feem ntau qhia qhovwider distribution range (siab dua variance), qhia txog qhov tsis sib xws ntawm cov khoom siv raw tswj thiab cov txheej txheem kev ruaj ntseg piv rau qee cov khoom lag luam thoob ntiaj teb-2
