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, ipleyiti yentsimbi yekhabhoni eyi-q235 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.
Iphepha elipholileyo lenziwe nge-coil eshushu-eshushu njengento ekrwada, iqengqeleke 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.
