Incazelo ye-SPCC amamaki ensimbi egoqiwe ebandayo

1 incazelo yegama
I-SPCCekuqaleni bekuyindinganiso yaseJapan (JIS) "ukusetshenziswa okuvamile kweishidi elibandayo eligoqiwe le-carbon steelkanye ne-strip" igama lensimbi, manje amazwe amaningi noma amabhizinisi asetshenziswa ngokuqondile ukukhombisa ukukhiqizwa kwawo kwensimbi efanayo. Qaphela: amamaki afanayo yi-SPCD (ishidi lensimbi ebandayo egingqika yekhabhoni kanye nomugqa wokugxiviza), i-SPCE (ishidi lensimbi egoqwe ebandayo kanye umucu womdwebo ojulile), SPCCK\SPCCCE, njll. (insimbi ekhethekile yamasethi we-TV), i-SPCC4D\SPCC8D, njll. (insimbi eqinile, esetshenziselwa amarimu ebhayisikili, njll.), ngokulandelanayo, okwehlukene izikhathi.

2 Izingxenye
Insimbi Japanese (JIS uchungechunge) ebangeni lensimbi ezejwayelekile kwesakhiwo ngokuyinhloko siqukethe izingxenye ezintathu ingxenye yokuqala impahla, ezifana: S (Steel) ukuthi insimbi, F (Ferrum) ukuthi insimbi; ingxenye yesibili yomumo ezahlukene, izinhlobo, kanye nokusetshenziswa, ezifana P (Plate) ukuthi ipuleti, T (Tube) ukuthi tube, K (Kogu) ukuthi ithuluzi; ingxenye yesithathu yezimpawu zenombolo, ngokuvamile amandla amancane okudonsa. Ngokuvamile amandla amancane okudonsa. Okufana njengokuthi: I-SS400 - i-S yokuqala yathi insimbi (Insimbi), i-S yesibili yathi "isakhiwo" (Isakhiwo), i-400 yomkhawulo ophansi wamandla aqinile we-400MPa, amandla aphelele we-400MPa we-Structural steel jikelele ene-tensile amandla angu-400MPa.

Okungeziwe: I-SPCC - ishidi lensimbi egoqiwe ebandayo ye-carbon kanye nomugqa wokusetshenziswa okuvamile, okulingana nebanga lase-China Q195-215A. Uhlamvu lwesithathu C luyisifinyezo se-Cold. Isidingo sokuqinisekisa ukuthi ukuhlolwa kwe-tensile, ekupheleni kwebanga kanye no-T kwe-SPCCT.

3 ngezigaba zensimbi
ElaseJapaneipuleti lensimbi eligoqiwe elibandayoamamaki asebenzayo: SPCC, SPCD, SPCE izimpawu: S - insimbi (Insimbi), P - plate (Plate), C - ebandayo rolling (kubanda), C yesine - evamile (evamile), D - isitembu grade (Draw), E - Ibanga elijulile lokudweba (Elongation)

Isimo sokwelashwa kokushisa: A-Annealed, S-Annealed + Flat, 8-(1/8) kanzima, 4-(1/4) kanzima, 2-(1/2) kanzima, 1-hard.

Izinga lokusebenza kokudweba: I-ZF- yokubhoboza izingxenye ezinomdwebo oyinkimbinkimbi kakhulu, i-HF- yokubhoboza izingxenye ezinomdwebo oyinkimbinkimbi kakhulu, u-F- wokubhoboza izingxenye ezinomdwebo oyinkimbinkimbi.

Isimo Sokuqeda Okungaphezulu: D - Ibuthuntu (amaroli acutshungulwa ngomshini wokugaya bese ayadutshulwa), B - Indawo Ekhanyayo (imiqulu ecutshungulwa ngomshini wokugaya).

Ikhwalithi yobuso: Indawo yokuqedela ene-FC ethuthukisiwe, indawo yokuqedela ephezulu ye-FB. Isimo, isimo sokuqedwa kwendawo, ukuqokwa kwekhwalithi yendawo ephezulu, ibanga lokudweba (le-SPCE kuphela), ukucaciswa komkhiqizo nosayizi, ukunemba kwephrofayela (ubukhulu kanye/noma ububanzi, ubude, ukungalingani).
