Customized zoo yeeb nkab nrog qib Q345C / D / E thiab specail nto kho
1. Nqe lus piav qhia
Hollow seem feem ntau yog siv nyob rau hauv steel qauv thiab machinery kev lag luam, tab sis zoo li qub thiab qib tsis tuaj yeem txaus siab rau qee qhov tshwj xeeb;
Yog li kom phim ntau thiab ntau qhov kev thov tshwj xeeb, peb lub tuam txhab npaj muab qee qhov kev thov sai sai hollow raws li hauv qab no:
1) Cov duab tshwj xeeb zoo li lub raj Oval, lub raj pob zeb diamond, lub khob cij, lub raj tshwj xeeb
2) qib tshiab xws li Q345B, Q345C, Q345D, Q355B, Q355C, Q355D, SS400, 304, 316, 310, 16Mo3, AL-6Xn thiab lwm yam
3) Nto zoo li epoxy primer, txhaj tshuaj blasting thiab lwm yam
Q345A, Q345B, Q345C, Q345D, Q345E yog qhov sib txawv ntawm cov qib zoo, nce los ntawm A txog E, feem ntau yog vim qhov sib txawv
Nyob rau hauv qhov cuam tshuam qhov kub thiab txias tshwm sim los ntawm cov ntsiab lus ntawm microelements xws li phosphorus thiab sulfur, uas txhais tau hais tias qhov cuam tshuam kub yog
sib txawv Thiab raj tshuaj muaj pes tsawg leeg mechanical zog.
Q345A qib tsis cuam tshuam; Q345B qib yog 20 degree poob siab ntawm chav tsev kub; Q345C qib yog 0 degree poob siab;
Q345D qib yog -20 degree poob siab; Q345E qib yog -40 degree poob siab. Ntawm qhov sib txawv ntawm kev poob siab, tus nqi ntawm kev poob siab kuj yog
txawv.
Q yield zog tsis tsawg dua 345Mp. Cov qib zoo qhia txog cov ntsiab lus tsis huv (carbon, manganese, silicon, sulfur,
phosphorus. Nws yog cov khoom tsis huv hauv cov hlau), thiab qhov ntxiv A, B, C, thiab D mus, qhov tsawg dua cov ntsiab lus impurity yog.
