Isheeti yesele yebhayisikhalo Q235B ezingqalene

Umbiko wokubanzi nokuhlola
1.Amalendlela amanqaku alendlela (C≤0.25%)
Ngaphandle kwehlangothi, ngasinye ukulayisha, ukuhlanganiswa okukhangelwa ngokuthabatha, kuzokufuneka ngeentsha ezinakalayo, isibheduka somncedisi, umzamo wobuhlungu, futhi ngezinto eziphakeme.
Ngokushesha: Q235 (isithombe saseSayina), A36 (isithombe sokho kweASTM sawemelika Amerika).

2.Amagaba amaphutha kwezintaba zesiCarbon (0.25%)
Inqanawe eluhle kunye nokubhekisana, kufanele kuhlola ngokusebenza (ngokushesha, ukugcina) ukuze uphinde ukusebenza ngokulandelayo, usetyenziswa ngamagaba ophakathi, amageji, amashafu, noma esinye.
Amanti amahlukileyo: 45# i-steel (umthetho waseChina), 1045 (umthetho waseAmerica).

3.Amagaba amaphutha kakhulu kweziCarbon (C>0.6%)
Ukuphakameho okukhulu kodwa kuhlabelekelwa, usetyenziswa ngokuphezulu kwiimbali, amasiphi, amathuluzi namanye amaphephandaba omahluke.
Imfano: T8, T10 (ithooli yesikhe).

Inqubo Yokukhiqiza
1.Iplenti yesitshalo sesifomu esisetyenzisiwe ngomhlabathi: isetyenziswa ngendawo eliphakathi lokugcina ukusetyenziswa kakhulu, ngenqanawe yokuxhumana emasipheni, umsukelo wakwesinye >1.5mm, uphambo oluncane, usebenziswayo ngokulandelana nokubheka.

2.Iplenti Yesitshalo Sesifomu Esisetyenzisiwe Ngemvula: isetyenziswa ngendawo yemvula, yenqanawe engaphansi kakhulu, ubungako obungaphezu kwalokhu kunye nekufakelwa engaphakathi (0.2~4mm), usebenziswayo ngokulandelana nokungena amanye amagadhi. Iphepha amaphethi, kakhulu.

3.Amagadi Amalime/Ama-coated Sheet: amalime ama-coated amahhweba okuhlola ukusuka komhlaba kwi-carbon steel sheet ukuvumela le ndlela lokusebenza (ngokushesha galvanised sheet lokugcina, lokuphuma amafuthi).

Amane aKhubeka kweNgcwala
1.Amagcinyi:

Ukuphakamisa okukhulu, uphangene ngenqanawe, kushaywa ngokucinile (ukugcina, ukusuka, ukubhukuda).

Amane azikahlelwa ngeendlela zokuhlola umoya (ngisho. ukusuka wokuquka ukuze uvumele amanxaso, ukusuka wokulanda ukuze uvumele umangaliso).

2.Amayiselo:

Ukuphakamisela kumaphandle kwesikhombisi esincane, kufuneka kuhlulekwe yinkathelo noma ukuphuma (phinda phantse i-stainless steel).

Ubungena bethwelaka emasipheni (ihlobo lesiThayiphi lesoSutheni sibethwelaka ngokushaya).

Amagama amancane kwezilimi Isicelo
1.Isigodi sasezintsha: iimofu zesiHayo, amabridji, amabhele engezansi.

2.Isigodi sesibhedlela: ichhasi lembala, amabhokisi ezikhathaleleyo, ifreime yamashini nezinye izinhlelo.

3.Amaninzi amahhabe: amathuluzi wemali, umphakathi wefurniture, ashelf.

4.Isenzo nesiphumo: amadeke edende, amathetha leraili, amaphayipayi yebhuleni.

Amastandithi apha neemakhetho
1.China: Q195, Q235, Q345 (GB⁄T 700, GB⁄T 1591).

2.Amerika: A36, A516 (ASTM).

3.Urope: S235JR, S355JR (EN 10025).

4.Japan: SS400 (JIS G3101).

Amazwelo ezidingekileyo
1.Inkonzo yokuhlala: umgawulo omusha noma ofaneleleyo kufuneka ukhethise amasheba egalvanisedwe noma ushintele isitesheli.

2.Ingeniso yenqanawe: Ukuhlanganiswa kufuneka uhlobo lwenqanawe lokuhlola i-low carbon steel; ukuthi okudingekileyo ngokubonakali kufuneka ukhethise i-high carbon steel noma usebenzise uphandleni lwesihlanu.

3.Isilinganiso: I-carbon steel iyishiyangaphandle kakhulu kunye ne-alloy steel noma istesheli esitesheli, iyafuneka emigomo engamadoda angcono yobudlelwano.
