Ingcaciso ye-SPCC amabakala entsimbi eqengqelekayo abandayo

1 inkcazo yegama
SPCCekuqaleni ibingumgangatho waseJapan (JIS) "ukusetyenziswa ngokubanzi kwesheet carbon steel epholileyo eqengqiwekwaye strip "igama lentsimbi, ngoku amazwe amaninzi okanye amashishini asetyenziselwa ngokuthe ngqo ukubonisa imveliso yawo yentsimbi efanayo. Qaphela: amabakala afanayo yi-SPCD (icwecwe elibandayo le-carbon steel sheet kunye ne-strip for stamping), i-SPCE (i-carbon steel sheet ebandayo kwaye i-strip for deep drawing), SPCCK\SPCCCE, etc. (intsimbi ekhethekileyo yeesethi zeTV), SPCC4D \ SPCC8D, njl. (intsimbi eqinile, esetyenziselwa iirim zebhayisikili, njl.), ngokulandelanayo, kwiimeko ezahlukeneyo.

2 Amacandelo
intsimbi Japanese (JIS series) kwibakala yentsimbi yesakhiwo eqhelekileyo ikakhulu iqulathe iinxalenye ezintathu inxalenye yokuqala yezinto, ezifana: S (Steel) ukuba intsimbi, F (Ferrum) ukuba intsimbi; inxalenye yesibini yeemilo ezahlukeneyo, iintlobo, kunye nokusetyenziswa, ezifana P (Plate) ukuba ipleyiti, T (Tube) ukuba ityhubhu, K (Kogu) ukuba isixhobo; isahlulo sesithathu seempawu zenani, ngokubanzi amandla e-tensile amancinci. Ngokubanzi amandla okuqina asezantsi. Ezinje: SS400 - i-S yokuqala yathi intsimbi (Steel), i-S yesibini yathi "isakhiwo" (iSakhiwo), i-400 yomlinganiselo ophantsi we-tensile yamandla we-400MPa, amandla e-tensile iyonke ye-400MPa ye-Structural steel jikelele ene-tensile amandla e-400MPa.

I-Supplementary: I-SPCC - i-carbon iron sheet epholileyo epholileyo kunye ne-strip yokusetyenziswa ngokubanzi, ilingana ne-China Q195-215A ibakala. Unobumba wesithathu u-C sisishunqulelo se-Cold ebandayo. Kufuneka kuqinisekiswe ukuba uvavanyo lwe-tensile, ekupheleni kwebakala kunye no-T lwe-SPCCT.

3 ukuhlelwa kwentsimbi
EyaseJapanipleyiti yentsimbi yentsimbi epholileyo epholileyoamabakala asebenzayo: SPCC, SPCD, SPCE iisimboli: S - steel (Steel), P - ipleyiti (Plate), C - ebandayo rolled (kubanda), yesine C - eqhelekileyo (eqhelekileyo), D - stamping grade (Draw), E - umzobo onzulu (Elongation)

Ubume bonyango lobushushu: A-Annealed, S-Annealed + Flat, 8-(1/8) nzima, 4-(1/4) nzima, 2-(1/2) nzima, 1-nzima.

Umzobo wenqanaba lokusebenza: i-ZF-yeendawo zokubhoboza ezinomzobo onzima kakhulu, i-HF-yeendawo zokubhoboza ezinomzobo onzima kakhulu, i-F-yeendawo zokubethelela ngomzobo onzima.

Isimo sokuGqibela uMphezulu: D - I-Dull (imiqulu ecutshungulwayo ngomatshini wokusila kwaye emva koko idutyulwe i-peened), B - I-Bright Surface (imiqulu ecutshungulwa ngomatshini wokusila).

Umgangatho womphezulu: I-FC-advanced finishing surface, FB-higher finishing surface. Imeko, umgangatho wokugqiba umgangatho, ukutyunjwa komgangatho ophezulu, ibakala lokudweba (kwi-SPCE kuphela), ukucaciswa kwemveliso kunye nobukhulu, ukuchaneka kweprofayili (ubukhulu kunye / okanye ububanzi, ubude, ukungalingani).
