Cov txheej txheem ntau lawm ntawm SS400 kub dov steel phaj

SS400 kub dov structural steel phaj yog ib hom hlau rau kev tsim kho, nrog rau cov khoom siv zoo heev thiab kev ua haujlwm, dav siv hauv kev tsim kho, txuas hniav, nkoj, tsheb thiab lwm yam.

Cov yam ntxwv ntawm SS400kub dov steel phaj

SS400 kub dov structural steel phaj yog lub siab-lub zog qis alloy qauv steel, nws lub zog tawm los ntawm 400MPa, nrog rau cov khoom siv zoo heev thiab kev ua haujlwm. Nws lub ntsiab nta yog raws li nram no:

1. Lub zog muaj zog: SS400 kub dov cov qauv steel phaj muaj lub zog muaj zog thiab tensile lub zog, uas tuaj yeem ua tau raws li qhov yuav tsum tau muaj zog ntawm kev tsim kho, txuas hniav, nkoj, tsheb thiab lwm yam.

2. Kev ua tau zoo heev: SS400 kub dov steel phaj muaj qhov zoo weldability thiab processability, thiab muaj peev xwm ua tau raws li ntau yam kev ua, xws li txiav, khoov, drilling thiab lwm yam.

3. Zoo heev corrosion kuj: SS400 kub dov steel phaj muaj corrosion kuj zoo tom qab kho deg, thiab muaj peev xwm ua tau raws li qhov yuav tsum tau siv nyob rau hauv ntau qhov chaw.

 

Daim ntawv thov ntawmSIB 400kub dov structural steel phaj

SS400 kub dov steel phaj yog dav siv hauv kev tsim kho, txuas hniav, nkoj, tsheb thiab lwm yam. Nws cov ntawv thov tseem ceeb yog raws li hauv qab no:

2. Choj teb: SS400 kub dov structural steel phaj yuav siv tau nyob rau hauv kev tsim cov choj lawj daim hlau, kab teeb thiab lwm yam structural qhov chaw, nrog zoo heev durability thiab anti- qaug zog zog, kom tau raws li qhov yuav tsum tau ntawm kev siv cov choj.

3. Nkoj teb: SS400 kub dov cov qauv steel phaj tuaj yeem siv rau hauv kev tsim cov qauv ntawm cov nkoj, nrog rau kev tiv thaiv zoo heev thiab kev ua haujlwm, kom ua tau raws li cov kev cai ntawm kev siv cov nkoj.

4. Tsheb teb: SS400 kub dov steel phaj tuaj yeem siv rau hauv kev tsim cov tsheb npog, thav ntawv thiab lwm yam khoom siv, nrog rau cov khoom siv zoo heev thiab kev ua haujlwm, kom ua tau raws li cov kev cai ntawm kev siv tsheb.

 

SS400 kub dov qauv steel phaj txheej txheem ntau lawm muaj xws li smelting, nruam casting, dov thiab lwm yam txuas. Cov txheej txheem ntau lawm yog raws li nram no:

1. Smelting: siv hluav taws xob rauv los yog converter steel smelting, ntxiv qhov tsim nyog tus nqi ntawm alloying ntsiab los kho cov neeg kho tshuab zog thiab kev ua tau zoo ntawm hlau.

2. Nruam casting: cov hlau tau los ntawm smelting yog poured rau hauv lub nruam casting tshuab rau solidification, sib sau billets.

3. Rolling: lub billet yuav raug xa mus rau lub tshuab dov rau dov, kom tau txais cov lus qhia tshwj xeeb ntawm cov phaj steel. Nyob rau hauv cov txheej txheem dov, qhov yuav tsum tau tswj qhov kub thiab txias, ceev thiab lwm yam tsis zoo los xyuas kom meej tias cov khoom siv ntawm cov hlau phaj thiab kev ua haujlwm.

4. Kev kho deg: dov ntawm cov hlau phaj rau kev kho deg, xws li descaling, painting, thiab lwm yam, txhawm rau txhim kho corrosion kuj thiab kev pab cuam lub neej ntawm steel phaj.
