Ishidi eligoqiwe elibandayowuhlobo olusha lomkhiqizo olucindezelwa ngokwengeziwe futhi lucutshungulweishidi eligoqiwe elishisayo. Ngenxa yokuthi iye yabhekana nezinqubo eziningi zokugoqa ezibandayo, izinga layo eliphezulu lingcono nakakhulu kuneshidi eligoqiwe elishisayo. Ngemuva kokwelashwa okushisa, izakhiwo zayo zemishini nazo zithuthukisiwe kakhulu.
Ngokwezidingo ezahlukene zebhizinisi ngalinye lokukhiqiza,ipuleti eligoqiwe elibandayongokuvamile ihlukaniswe ngamazinga amaningana. Amashidi agoqwe abandayo ahanjiswa ngamakhoyili noma amashidi ayisicaba, futhi ukushuba kwawo kuvame ukuvezwa ngamamilimitha. Ngobubanzi, ngokuvamile atholakala ngosayizi ongu-1000 mm no-1250 mm, kanti ubude buvamise ukuba ngu-2000 mm no-2500 mm. Lawa mashidi agoqwe abandayo awagcini nje ngokuba nezinto ezinhle kakhulu zokwakha kanye nekhwalithi enhle yendawo, kodwa futhi ahamba phambili ekuphikiseni ukugqwala, ukumelana nokukhathala kanye nobuhle. Ngenxa yalokho, zisetshenziswa kabanzi kwezezimoto, ezokwakha, ezisetshenziswa ekhaya, ezisetshenziswa ezimbonini nakweminye imikhakha.
Amabanga eshidi eligoqiwe elibandayo
Amabanga asetshenziswa kakhulu yilawa:
Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06 njalonjalo;
I-ST12: Ikhonjiswe njengebanga lensimbi elivame kakhulu, eline-Q195,I-SPCC, DC01impahla yebanga ngokuyisisekelo iyafana;
I-ST13/14: Ikhonjiswe inombolo yensimbi yebanga lokunyathela, futhi 08AL, SPCD, DC03/04 impahla yebanga iyafana ngokuyisisekelo;
I-ST15/16: Ikhonjiswe njengenombolo yensimbi yebanga lokunyathela, futhi i-08AL, SPCE, SPCEN, DC05/06 grade material iyafana.
Japan JIS incazelo impahla ejwayelekile
Imele ini i-SPCCT ne-SPCD?
I-SPCCT isho ishidi lensimbi egoqiwe ye-carbon kanye nomcu oqinile oqinisekisiwe ngaphansi kwezinga le-JIS laseJapane, kuyilapho i-SPCD isho ishidi lensimbi egoqelwe ebandayo kanye nomucu wokugxiviza ngaphansi kwezinga elijwayelekile le-JIS laseJapane, kanti ozakwabo waseShayina ungu-08AL (13237) wesakhiwo sekhabhoni yekhwalithi ephezulu. insimbi.
Ukwengeza, mayelana nekhodi yokushisa yeshidi lensimbi egoqwe ebandayo kanye nomugqa, isimo esishubile singu-A, ukushisa okujwayelekile kungu-S, ukuqina okungu-1/8 kungu-8, 1/4 ubulukhuni 4, 1/2 ubulukhuni bu-2, futhi bugcwele. ubulukhuni bungu-1. Ikhodi yokuqeda ebusweni ithi D yokuqeda okungacwebezeli, futhi B ukuqeda okugqamile, isb, i-SPCC-SD isho ishidi lensimbi egoqelwe yekhabhoni elibandayo elisetshenziswa ngokujwayelekile ngokufudumeza okujwayelekile futhi ukuphela okungacwebezeli; I-SPCCT-SB isho ishidi lensimbi yensimbi epholile epholile, egqamile; futhi i-SPCCT-SB isho ishidi lensimbi elipholile elipholile eligoqekayo elizosetshenziswa okuvamile elinokushisa okujwayelekile nokuqeda okungacwebezeli. Ukushisa okujwayelekile, ukucubungula okukhanyayo, ishidi lekhabhoni eligoqiwe elibandayo elidingekayo ukuze kuqinisekiswe izakhiwo zemishini; I-SPCC-1D ivezwa njengeshidi lensimbi eliqinile, elingacwebezeli eligoqiwe elibandayo.
Ibanga lensimbi yesakhiwo semishini ivezwa ngale ndlela elandelayo: I-S + carbon content + ikhodi yezinhlamvu (C, CK), lapho okuqukethwe kwekhabhoni enenani elimaphakathi * 100, uhlamvu C lusho ikhabhoni, uhlamvu K lusho insimbi eshisiwe.
Incazelo yezinto ezibonakalayo zaseChina GB
Ngokuyisisekelo ihlukaniswe ngokuthi: Q195, Q215, Q235, Q255, Q275, njll. U-Q ubonisa ukuthi indawo yokukhiqiza yensimbi "isivuno" uhlamvu lokuqala lwegama elithi hanyu pinyin, 195, 215, njll. libonisa ukuthi iphuzu lesivuno senani. ukwakheka kwamakhemikhali kusuka kumaphuzu, izinga eliphansi le-carbon steel: Q195, Q215, Q235, Q255, Ibanga le-Q275, lapho okuqukethwe kwekhabhoni kukhulu, kuyanda okuqukethwe kwe-manganese, ipulasitiki yayo izinzile.
