IDC03 emkhuhlane yeesitheko esinamandla

Izandla zokugcina
1.Amagcinintshi: Isifumelelo nesikhephe ngamandla, kunye namangane emangini kusihlalo, imanganese, ifosfhoru, ishulwani kunye nezinyathela ezinnye. Ukusuka kokuthi ukungakho elingana nesikhephe uhlukanisiwe ngokusho:

①I-low carbon steel coil (C ≤ 0.25%): uphawuli phakathi, kufanele ukuphatha, kuzokubona kwi-stamping, ukusondeza.

②I-medium carbon steel coil (0.25% < C ≤ 0.6%): ungenzi emnandi, kusukele kwezinto zomsebenzi.

③I-high carbon steel coil (C>0.6%): umoya omkhulu, akunqumeke, kodwa kuhlukele kwezinto zakhiwo, amasipha.

2. Ukuphatha kwezansi: ungaphindwe ngamabili hot rolled coil (noma i-oxide skin esihlukeni), cold rolled coil (esihlukeni sikhulu), galvanised coil noma colour coated coil.

3. Izicwangciso: umbawulo obungakho 0.2 ~ 25mm, umdabu lwangoku lalimangeni 2000mm noma lokugcina, umuthi wemicotho welalimangeni amakhanda.

inqubo Yokukhiqiza
1. hot rolled carbon steel coil: umlayo wakhiwe ngendlela eliphakathi lokuhlula kunye nokuphinda, uphawu oluncane kodwa usukela esihlukeni, kusetyenziswa ngokubanzi kwi-structural parts.

2. Cold rolled carbon steel coils: amahot rolled coils akhiwe ngemuva kokulima kunye nokuphinda kwesintsi, nabombawulo olunqinisekileyo kunye nesihlukeni esikhulu, kusetshenziswa ngokubanzi kwi-precision processing.

3. Ukuphatha okufolofolweni: ungalawuliwe, ulayishe noma uhlalelwe ukuyibuyelela isibhedlela sesilimi.

Isicelo amasimu
1.Isimu sokuhlola: istrukti yesiqephu, umbhovu, amabridji (amasiko ashotholeni akuxoxwa ngokupheleleyo).

2.Ukugcina imibhayithi: izipaneli zombhalo, iziphethelo zesayithi (amasiko ashotholeni acala noma amagalavini).

3.Iphepha amashumi: ifiridhijiyi, ishiba leshayela (amagalavini noma amasiko atholakaleyo).

4.Ukuhweba kwezinye izinto: amaphethelo, amaghiya (amasiko ashotholeni ephakathi nekhononi lesicabango).

5.Amagaba nemikhomphulo: amagaba olushiselwe, iistikha lolunxibelelwe (amasiko ashotholeni akuxoxwa ngokupheleleyo elishonaleni).

Amahlelo kunye nezinyathelo
1.Amagcinyi:

Iphutha enguquleyo, umnotho womdlalo okwesintsha, uphawulo olunomoya.

Amanqaku angaphindwe ngokusebenzisa umoya (ngokusho quenching, tempering).

2.Amayiselo:

Ukuninwa kwezintaba (kufanele kuhlalele ukuphindezelo lwezinselo).

Ukuthengisa okuncane kweemoti ephakeme, ukusibeziswa kwesikhashana kusibi khona.

Amasethi namakhombotshwana
1.Amagraidi ezinhloko:

①China: Q195, Q235 (emotini); 45# (emotini womphakathi); 65Mn (emotini ephezulu).

②Ulwandle: ASTM A36, JIS G3131 (SPHC), EN DC01.

2.Inqubo yokuhlola: Kufuneka uvumele amabomu engezansi, ububanzi be-roll, isihlengi eside (ngokugcina 508mm okanye 610mm) kunye nembuzo yokuqinisekisa kwe-surface.

Ukuphela ngenye imibono elinye lesteeli
1.vs imikholisi yesiteeli: imikholisi ye-carbon steel zingaphambili kwindaweni ekhona ngokushesha kodwa angazama ukukhupha.

2.vs imikholisi yesiteeli le-alloy: imikholisi ye-carbon steel ngakho lizinzulu ezininzi ngokuthi kodwa zingafane kuhle ukuphatha.

Amacala we-carbon ayiqondisiwe ngokuphezulu kwiqhude lokusebenza ngenqanawe yezilimi zabo ngokuthi zihlukomeleyo kunye nephandleni, futhi ukusetha okuhlukaniswe kwe-carbon, uprosesu kunye nokugcina kwesiphumo sesakhiwo kufanele luhambise phakathi ne-umthwalo.
