Ikhoyila yentsimbi yeSPCC eQinisiweyo eQinisiweyo

Inkcazelo emfutshane:

Igama: Ikhoyili yentsimbi eQiniweyo

Intsimbi yekhabhoni epholileyo (SPCC, SPCD, SPCE), intsimbi ephantsi yekhabhoni kunye ne-ultra-low carbon steel (DC01 / St12, DC03 / St13, DC04 / St14), intsimbi ye-automotive stamping (DC01-Q1, DC03-Q1, DC04 - I-Q1), i-carbon structural steel strips ebandayo (Q235, St37-2G, S215G), i-alloy low-alloy high-high-high-rolled steel strips (JG300LA, JG340LA), njl.

Uluhlu lokutyeba: 0.1mm-0.45mm

ububanzi ububanzi: 700mm-1000mm

Izinto eziphathekayo: SPCC, SPCC, SPCD, SPCE, DC01, St12, DC03, St13, DC04, St14, Q235, St37-2G, S215G, JG300LA, JG340LA

Iimpawu: Ngenxa yokuba ayifakwanga, ubunzima bayo buphezulu kakhulu (i-HRB inkulu kune-90), kwaye ukusebenza komatshini kumbi kakhulu. Kuphela inkqubo elula yokugoba engaphantsi kwama-90 degrees (i-perpendicular ukuya kwicala elijikelezayo) inokwenziwa. Ezinye ii-mell zentsimbi zinokuvelisa ukucutshungulwa okuphindwe kane.

Isishwankathelo sekhoyili eqengqelekayo ebandayo

Ikhoyili epholileyo epholileyo yenziwe ngekhoyili eshushu. Kwinkqubo epholileyo epholileyo, i-coil eshushu iqengqeleka ngaphantsi kweqondo lokushisa le-recrystallization, kwaye intsimbi ejikeleziweyo ngokubanzi igqitywe kwiqondo lokushisa. Ishiti lentsimbi elinomxholo ophezulu wesilicon linobuqhophololo obuphantsi kunye neplastikhi ephantsi, kwaye kufuneka ifudunyezwe ifike kuma-200 °C phambi kokubanda kuqengqeleke. Ekubeni i-coil epholileyo epholileyo ayishushu ngexesha lenkqubo yokuvelisa, akukho ziphene ezifana ne-pitting kunye ne-iron oxide ehlala ifumaneka kwi-hot rolling, kunye nomgangatho ophezulu kunye nokugqiba okulungileyo.

Inkqubo yokuveliswa kwekhoyili eqengqelekayo

I-coil epholileyo epholileyo yenziwe nge-coil eshushu eshushu, kwaye inkqubo yayo yokuvelisa idla ngokudlula kwiinkqubo eziphambili ezifana nokulungiswa kwezinto eziluhlaza, ukuqengqeleka okubandayo, ukunyangwa kobushushu, ukulinganisa kunye nokugqiba.

Ukusebenza kweMveliso yeCoil eQingiweyo

Umqulu kunye nethebhulethi phantse iphakheji enqunyiwe. Ikhoyili epholileyo ifumaneka ngokukhetha kunye nokubanda ukuqengqeleka kwekhoyili eshushu. Kunokuthiwa luhlobo oluthile lwekhoyili ebandayo. Ikhoyili epholileyo eqengqelekayo (imeko efakwe kwi-annealed): Ikhoyili eshushu esongwayo ifunyanwa ngokuchola, ukuqengqeleka okubandayo, ukufakwa kwe-hood, ukulinganisa, (ukugqiba).

Kukho iiyantlukwano ezi-3 eziphambili phakathi kwazo:

Ngenkangeleko, ikhoyili epholileyo ngokubanzi ithambile.

Amashiti aqengqelekayo abandayo afana nomgangatho womphezulu, ubume kunye nokuchaneka komgangatho angcono kuneekhoyili ezibandayo.

Ngokubhekiselele ekusebenzeni, i-coil epholileyo efunyenwe ngokuthe ngqo emva kwenkqubo ebandayo yokuqengqeleka kwe-coil eshushu eqengqelekayo isebenza nzima ngexesha lokuqengqeleka okubandayo, okukhokelela ekonyukeni kwamandla esivuno kunye nenxalenye yoxinzelelo lwangaphakathi oluseleyo, kunye nenkangeleko yangaphandle "inzima". ". Ibizwa ngokuba yicoil ebandayo.

Ngoko ke, amandla okuvelisa: i-coil epholileyo inkulu kune-coil epholileyo epholileyo (i-annealed state), ukwenzela ukuba i-coil epholileyo (i-annealed state) ithandeke ngakumbi kwi-stamping. Ngokuqhelekileyo, imeko yonikezelo olungagqibekanga lweekhoyili eziqengqelekayo ezibandayo luyakhutshwa.
