Buka amafayela wehliswa okwenyelwa ngokushesha

Izindlu zokunquma ngokuchaza yindlela entsha yokwenza okwenziwa ngokunquma kwezindlu zokunquma ngokwephakathi. Ngoba kwenziwe kakhulu imicimbo yokunquma ngokuchaza, ubunzima bokuhle kwayo kungenaneni okunqunyiwe ngokunquma ngokwephakathi. Emva kokunquma ngokwephakathi, imithi yokusebenza kwalo iyaphansi kakhulu.

Ngokwemiphiko yasekelo kanye nezidinga zokwenza kwezinye zikhowudi, izicathami zokwenza ngokushesha zihlukaniswa ngeminyaka. Iziphanti zokwenza ngokushesha zinikezwa ngokweqile kanye neziphanti eziqile, kanti ubude bazo ngokuvamile bitholakala kumilimitha. Ngokwengqondo yobubanzi, ziyatholakala kububanzi be 1000 mm kanye ne 1250 mm, nangabe ubude bazo ngokuvamile bu 2000 mm kanye ne 2500 mm. Le ziphanti zokwenza ngokushesha ziyabonisa ukuba nezici ezinhle zokwenza kanye neqile lekhe lasekelo, kodwa futhi ziyabonisa ukuba nezici ezinhle zokulungiselela kwekholo, ukulungiselela kwekholo kanye nezici ezinhle zokubona. Ngaleyo ndlela, ziyasetshenziswa kakhulu kuzo zikhanda zokuthutha, ukudlala, izindlela zokusebenza, izilungiselelo zokusebenza kanye nezinye izikhanda.

Izinga leziphanti eziqile eziyisisekelo

Izinga eziyisisekelo ziyisisekelo:

Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06 kanye namanye;

ST12: Ibonisa ukuthi yizinga lesteel ephawulwayo kakhulu, ngeQ195, SPCC, DC01 ingxenye yamaphethini yisidingo esifanayo;

ST13/14: Ikhombiswa ngokuthi yilambhu yesilinda sekaleni esibonakalayo, futhi i-08AL, SPCD, DC03/04 iyageyithi yamagugu ngokuphela;

ST15/16: Ikhombiswa ngokuthi yilambhu yesilinda sekaleni esibonakalayo, futhi i-08AL, SPCE, SPCEN, DC05/06 iyageyithi yamagugu ngokuphela.

Inkcazo yematerial ngokwesigaba le-JIS yeJapan

Kuthini i-SPCCT kanye no-SPCD?

I-SPCCT ithi i-steel sheet esihlukahlukene nezinhlobo zokwenza i-tensile strength ngaphansi kwegama le-JIS yeJapan, futhi i-SPCD ithi i-steel sheet esihlukahlukene nezinhlobo zokwenza stamping ngaphansi kwegama le-JIS yeJapan, futhi iyageyithi yayo yaseChina iyaguqwa ku-08AL (13237) i-high quality carbon structural steel.

Ngaphezulu, mal concerning the tempering code of cold rolled carbon steel sheet and strip, umsebenzi wokucula ngu-A, ukucula okuhle kuyi-S, 1/8 engqokatha ngu-8, 1/4 engqokatha ngu-4, 1/2 engqokatha ngu-2, futhi engqokatha yabanzi ngu-1. Imbobo yesivinini ngu-D kumaqo angagqangi, ne-B kumaqo ongagqangi, isb., SPCC-SD ithi carbon steel sheet enguqulwe yisigaba esijwayelekileyo nekuculwa okuhle futhi engagqangi; SPCCT-SB ithi carbon steel sheet enguqulwe yisigaba esijwayelekileyo, umqamuli oqagunu; futhi SPCCT-SB ithi carbon steel sheet enguqulwe yisigaba esijwayelekileyo, umqamuli oqagunu enguqulwe yisigaba esijwayelekileyo futhi engagqangi. Ukucula okuhle, ukuculwa okuqagunu, carbon sheet enguqulwe kudinga ukuthi kuhlanjwe izici zemifanekiso; i-SPCC-1D ishwa njengeqile, umqamuli oqile enguqulwe yisigaba esijwayelekileyo.

Isigaba se stal yenqanawe yomqondo usebenza ngokulandelayo: S + ubungo lwamakhasboni + amagama wokuchaza (C, CK), lapho ubungo lwamakhasboni lubi ngokuphakathi * 100, amagama a-C ibhala amakhasboni, amagama a-K ibhala isiteleni sekarboni.

Incazelo yematerial yesiGB yaseChina

Yahlukaniswa ngokusho: Q195, Q215, Q235, Q255, Q275, njll. Q ibhala indawo yokuthula yemitha "yield" owafaka ku hanyu pinyin, 195, 215, njll. ibhala ubungo lwendawo yokuthula ngokuchanekileyo, isigaba se amakhasboni encane: Q195, Q215, Q235, Q255, Q275, ngokuphakade kwe amakhasboni, ngokuphakade kwe mankhasi, ngokuphakade kwe plasticity.
