Kutengesa Kunopisa Kwesimbi Coil/Sheet
Mechanical properties ye
(1) Kusimba kwesimba (σb) :iyo yakanyanya simba (Fb) yemuenzaniso panguva yekuputsika kwakapatsanurwa nekushushikana (σ) kwenzvimbo yepakutanga yemuchinjikwa (So) yemuenzaniso.Chikamu chesimba rekusimba (σb) iN/mm2(MPa).Inomiririra huwandu hwepamusoro hwesimbi yesimbi kuti irambe kukanganisa pasi pekukakavadzana.Ipo: Fb-- simba guru rinotakurwa nemuenzaniso painotyoka, N (Newton); Saka-- Yekutanga-yepakati-chikamu nzvimbo yemuenzaniso, mm2.
(2) Poindi yegoho (σ S) :iyo goho poindi yesimbi ine chiitiko chegoho.Ndiko kushushikana uko iyo specimen inogona kuramba ichitambanuka pasina kuwedzera simba (kuchengeta nguva dzose) panguva yekumanikidza.Kana simba richidzikira, mapoinzi epamusoro neakaderera anofanirwa kusiyaniswa.Iyo unit yegoho poindi iNF/mm2(MPa).Iyo yekumusoro goho poindi (σ SU) ndiyo yakanyanya kushushikana isati yemuenzaniso isati yaburitsa uye simba rinodonha kekutanga.Yakaderera goho poindi (σ SL) : iyo shoma kushushikana muchikamu chegoho kana yekutanga yenguva pfupi isingatariswe.Ipo Fs iri simba rekuburitsa (nguva dzose) yemuenzaniso panguva yekusimba, N (Newton) Ndizvo zvakaita nzvimbo yepakutanga-yakachinjika yemuenzaniso, mm.2.
(3) Kureba mushure mekutyoka :(σ)mukuedza kwekusimba, kureba ndiyo chikamu chehurefu chakawedzerwa nechiyero chedaro chemuenzaniso mushure mekutyoka kana zvichienzaniswa nehurefu hwechinhambwe chepakutanga.Iyo unit ndeye%.Ikoko: L1-- chinhambwe chemuenzaniso mushure mekutyoka, mm;L0-- Yekutanga kureba kureba kwemuenzaniso, mm.
(4) Kuderedzwa kwechikamu :(ψ)mutest tensile, chiyero chekudzikisira kwakanyanya kwepamuchinjikwa-sectional nzvimbo pane yakaderedzwa dhayamita yemuenzaniso mushure mekudhonzwa uye yepakutanga yepakati-chikamu nzvimbo inonzi kuderedzwa kwechikamu.ψ inoratidzwa mu%.Ipo, S0-- nzvimbo yepakutanga yemuchinjikwa-chikamu chemuenzaniso, mm2;S1-- Iyo shoma-yepakati-chikamu nzvimbo pane yakaderedzwa dhayamita yemuenzaniso mushure mekutyoka, mm2.
(5) Kuoma indekisi:kugona kwesimbi zvinhu kupikisa zvinhu zvakaoma kuti indent pamusoro, inozivikanwa sekuoma.Zvinoenderana neyeyedzo nzira uye chiyero chekushandisa, kuomarara kunogona kukamurwa kuita Brinell kuomarara, Rockwell kuomarara, Vickers kuomarara, Shore kuomarara, kuomarara kudiki uye kuomarara kwekushisa kwakanyanya.Inowanzo shandiswa pombi zvinhu zvine brinell, rockwell, Vickers kuoma 3 mhando.
(6) Brinell kuoma (HB) :neimwe dhayamita yebhora resimbi kana yakaoma alloy bhora, ine yakataurwa bvunzo simba (F) yakatsikirirwa mune yesample yepasi, mushure menguva yakatarwa yekubata kubvisa iyo bvunzo simba, kuyerwa kweiyo sampuli yepasi indentation dhayamita (L).Nhamba yekuomarara yeBrinell ndiyo quotient yesimba rekuyedza rakakamurwa nepamusoro penzvimbo yedentation sphere.Inoratidzwa muHBS, iyo unit iN/mm2(MPa).
Mechanical properties yesimbi isina tsvina mahwendefa, maitiro ekuita
(1) Carbon;Iyo yakakwira iyo kabhoni yemukati, iyo yakanyanya kuoma simbi, asi iyo shoma plastiki uye ductile ndiyo.
(2) Sarufa;Imarara anokuvadza musimbi, simbi ine sarufa yakakwira mukupisa tembiricha yekumanikidza, iri nyore kutsemuka, inowanzonzi inopisa brittleness.
(3) Phosphorus;Inogona kuderedza zvakanyanya plastiki uye kuoma kwesimbi, kunyanya pakupisa kwakadzika, iyo yakanyanya kuoma, uye chiitiko ichi chinonzi kutonhora brittleness.Mumhando yepamusoro simbi, sarufa uye phosphorus inofanira kunyatsodzorwa.Asi kune rimwe divi, yakaderera kabhoni simbi ine yakakwira sarufa uye phosphorus, inogona kuita kuti kucheka kwayo kuve nyore kutyora, kuvandudza machinability yesimbi yakanaka.
(4) Manganese;Inogona kuvandudza kusimba kwesimbi, inogona kupera simba uye kubvisa yakashata mhedzisiro yesarufa, uye inogona kuvandudza kuoma kwesimbi, yakakwira alloy simbi ine yakakwira manganese content (yakakwirira manganese simbi) ine yakanaka kupfeka kuramba uye zvimwe zvinhu zvemuviri.
(5) Silicon;Inogona kuvandudza kuoma kwesimbi, asi plastiki uye kuoma kunoderera, simbi yemagetsi ine imwe huwandu hwesilicon, inogona kuvandudza iyo yakapfava magineti zvivakwa.
(6) Tungsten;Inogona kuvandudza kuoma kwakatsvuka, simba rekupisa uye kupfeka kusagadzikana kwesimbi.
(7) Chromium;Inogona kuvandudza kuomarara uye kupfeka kuramba kwesimbi, kunatsiridza kusimba kwekuora uye oxidation kuramba kwesimbi.
(8) Zingi;Kuti uvandudze kurwisana nekuora, iyo yakawanda simbi pombi (black pombi) inogadziriswa.Pombi yesimbi yakakamurwa kuita mhando mbiri dzekupisa dip galvanized simbi uye yemagetsi simbi zingi, inopisa dip galvanized layer gobvu, magetsi emagetsi mutengo wakaderera, saka kune galvanized simbi pombi.
Mechanical properties uye nzira dzekuchenesa mahwendefa esimbi asina tsvina
1. kushandiswa kwekutanga kwekunyungudutsa kuchenesa simbi, pamusoro peiyo organic kubviswa,
2. wobva washandisa maturusi ekubvisa ngura (waya bhurasho), bvisa yakasununguka kana kuti tilt scale, ngura, welding slag, nezvimwewo,
3. kushandisa pickling.
Galvanized yakakamurwa kuita inopisa plating uye inotonhora plating, inopisa plating haisi nyore kuita ngura, kutonhora plating iri nyore kuita ngura.
