Umphezulu Rockwell ubulukhuni of annealed plain carbon steel ngokuqhelekileyo 55+-3, kwaye ukuqina unnnealed-rolled hard-rolled strip intsimbi ingaphezulu kwama 80. Umcu obandayo kunye neshiti ngokubanzi zinobukhulu be-0.1-3mm kunye nobubanzi ye 100-2000mm;zombini zenziwe nge-hot-rolled strip okanye ipleyiti yentsimbi..
I-CRS sisishunqulelo sentsimbi epholileyo yesiNgesi, oko kukuthi, intsimbi eqengqelekayo ebandayo.Ibhekisela kwinkqubo yokuqengqeleka kwentsimbi.Umzekelo, q235 ipleyiti yentsimbi yentsimbi eqhelekileyo inokuqengqeleka ebandayo, kwaye 10# ipleyiti yentsimbi nayo inokuqengqeleka ebandayo.Ubunzima bayo bunokuba kumgangatho ohambelanayo ngokwebakala lensimbi elisetyenzisiweyo..
Leliphi ibakala leshiti eliqengqelekayo elilukhuni kune spcc?.
Iphepha elipholileyo lisisishunqulelo seshiti eliqhelekileyo lekhabhoni lolwakhiwo lwentsimbi epholileyo, eyaziwa ngokuba ishidi eliqengqelekayo, elaziwa njengephepha eliqengqelekayo, kwaye ngamanye amaxesha libhalwe ngempazamo njengephepha eliqengqelekayo.Ipleyiti ebandayo yenziwe ngentsimbi yentsimbi eqhelekileyo ye-carbon structural hot-rolled steel strip, eqhubeka ngokubanda-iqengqeleke ibe yintsimbi enobunzima obungaphantsi kwe-4mm..
Icwecwe elipholileyo lihlulwe libe: 1/8 nzima, 1/4 nzima, 1/2 enzima kunye nesimo esinzima esipheleleyo.Kukho ngokubanzi iiyunithi ezimbini eziphambili zexabiso lobulukhuni: HRB (Rockwell) HV (Vickers) ngolu hlobo lulandelayo: Isimboli yokwahlula umgangatho HRB (Rockwell) HV (Vickers) 1/8 nzima..
I-Pickling plate yi-hot-rolled plate ephantsi kwenkqubo efana ne-dephosphorization (ukususwa kwe-rust, i-residus, njl., eveliswa ngexesha lokutshisa okutshisa) kunye nezinye iinkqubo zokucoca umphezulu wokufumana ipleyiti yentsimbi kunye nokusebenza okungcono kunokushisa. -indawo eqengqelekayo.Inokubonwa kwinkqubo yayo yokuvelisa ukuba ukuqina kwayo kushushu kuqengqeleka ngebakala elifanayo..
Akukho mahluko ngokusisiseko kubulukhuni bomphezulu phakathi kokuqengqeleka okubandayo kunye negalvanized.Ngenxa yokuba i-galvanized surface ifakwe kuphela ngoluhlu lwezinc ukusuka kwi-microns ezimbalwa ukuya kwi-microns ezingama-20 kwi-substrate.I-substrates ngokubanzi i-cold-rolled kunye ne-hot-rolled.Ukuqina ikakhulu kuxhomekeke kwibakala lezinto eziphathekayo, kwaye amabakala ayahluka..
Thatha iDC01, DC03 njengomzekelo.I-DC01 umda ophezulu wamandla esivuno 280 DC03 umda ophezulu wamandla esivuno 240 , dc06+ze, zihambelana neshiti eliqengqelekayo elibandayo, inani limele ibakala lokunyathela, kwaye inani elikhulu.
Ishiti elipholileyo lenziwe nge-coil eshushu-eshushu njengento ekrwada, ijikelezwe kwiqondo lokushisa elingaphantsi kweqondo lokushisa, kwaye ubunzima bayo bumalunga ne-150HV.Iintsimbi zomatshini wokucheba ngokubanzi zenziwe ngentsimbi yesixhobo, ezinobunzima be-HRC55 ~ 58 °, ezinokusika uninzi lwazo.
