Ukuqina kwe-Rockwell engaphezulu kwe-annealed plain carbon steel ngokuvamile kungama-55+-3, futhi ukuqina kwensimbi engagoqeki eqinile egoqekayo bungaphezu kuka-80. Umugqa ogoqekayo kanye neshidi ngokuvamile linogqinsi luka-0.1-3mm nobubanzi ububanzi 100-2000 mm; zombili zenziwe nge-hot-rolled strip noma i-steel plate. .
I-CRS isifinyezo sensimbi egoqiwe yesiNgisi epholile, okungukuthi, insimbi egoqiwe ebandayo. Kubhekiselwa kunqubo yokugingqika yensimbi. Isibonelo, ipuleti le-carbon steel elijwayelekile elingu-q235 lingagoqeka ngokubanda, kanti ipuleti lensimbi elingu-10# nalo lingagoqwa ngokubanda. Ukuqina kwayo kungaba sezingeni elihambisanayo ngokwezinga lensimbi elisetshenzisiwe. .
Iliphi ibanga leshidi eligoqwe elibandayo eliqine kune-spcc? .
Ishidi eligoqiwe elibandayo liyisifinyezo seshidi eligoqelwe elibandayo le-carbon structural steel, elaziwa nangokuthi ishidi eligoqiwe ngokubanda, elivame ukubizwa ngokuthi ishidi eligoqiwe ngokubanda, futhi ngezinye izikhathi libhalwe ngephutha njengeshidi eligoqwayo. Ipuleti elibandayo lenziwe ngomucu wensimbi ojwayelekile we-carbon structural steel hot-rolled steel, ophinde ugodole ugoqeke ube yinsimbi enogqinsi olungaphansi kuka-4mm. .
Ishidi eligoqiwe elibandayo lihlukaniswe: 1/8 kanzima, 1/4 kanzima, 1/2 kanzima kanye nesimo esiqinile esigcwele. Ngokuvamile kunamayunithi amabili ayinhloko yenani lobulukhuni: HRB (Rockwell) HV (Vickers) kanje: Uphawu oluhlukanisa ikhwalithi i-HRB (Rockwell) HV (Vickers) 1/8 kanzima. .
Ipuleti le-Pickling ipuleti eligoqelwe elishisayo elingaphansi kwenqubo efana ne-dephosphorization (ukususwa kokugqwala, izinsalela, njll., ezikhiqizwa ngesikhathi sokuginqika okushisayo) nezinye izinqubo zokugqumisa phezulu ukuze kutholwe ipuleti lensimbi elisebenza kangcono kunokushisa. -indawo egoqiwe. Kungabonakala ngenqubo yayo yokukhiqiza ukuthi ubulukhuni bayo buyashisa bugoqwe ngebanga elifanayo. .
Akukho mehluko ekuqineni kwendawo phakathi kokugoqwa okubandayo kanye namathayela. Ngoba ingaphezulu elinothayela ligcwele kuphela ungqimba lwezinc ukusuka kuma-microns ambalwa kuya kuma-microns angaba ngu-20 ku-substrate. Ama-substrates ngokuvamile ayabanda futhi ayashiswa. Ubulukhuni ikakhulukazi buncike ebangeni lempahla, futhi amamaki ayahluka. .
Thatha i-DC01, DC03 njengesibonelo. I-DC01 umkhawulo ongaphezulu wamandla esivuno 280 DC03 umkhawulo ophezulu wamandla esivuno 240 , dc06+ze, ahambisana neshidi eligoqiwe elibandayo, inombolo imele ibanga lokunyathela, futhi inombolo enkulu.
Ishidi eligoqwe elibandayo lenziwe ngekhoyili egoqwe ngokushisayo njengempahla eluhlaza, egoqwe ekamelweni lokushisa elingaphansi kwezinga lokushisa lekristalu, futhi ubulukhuni balo bungaba ngu-150HV. Ama-blade omshini wokugunda ngokuvamile enziwa ngensimbi yamathuluzi, enobulukhuni be-HRC55~58°, engasika iningi lawo.
