Cov coils steel carbon cold rolled uas peb muab yog tsim raws li ASTM A1008/A1008M standard requirements. Peb tau ua kom tswj tau cov carbon content li 0.05% txog 0.25%. Qhov ratio zoo no ua qhov kev sib tshuam ntawm plasticity thiab lub zog ntawm cov khoom.
Raws li kev sim, tensile lub zog ntawm cov coil steel carbon txias dov tuaj yeem xav txog 370MPa txog 550MPa. Thiab raws li ASTM E8 test standard, nws elongation tuaj yeem nyob li 30% los ntau dua. Qhov kev sib raug zoo ntawm mechanical properties no ua rau nws yooj yim ua tau raws li kev xav tau thaum stamping los bending, tsis muaj cracking, thiab muab kev ntseeg siab rau cov nyob tom qab.
Peb muab ob hom kev kho mob: oiled (txwv tsis pub xeb thaum khaws) thiab qhuav (rau painting). Lub oiled finish siv food-grade mineral oil raws li FDA 21 CFR 178.3910, nyab xeeb rau kev siv khoom noj tsis ncaj. Peb cov skin-pass rolling process ua kom muaj qhov sib xws Ra 0.8-1.2μm surface roughness (ASTM B46.1), zoo rau hmoov txheej adhesion.
Kev slitting services? Peb siv carbide-tipped cut blades, uas tuaj yeem nyob ntse 30% ntev dua li cov pa steel hniav. Qhov no ua kom cov edge zoo, txawm tias thaum ua cov xaj loj txog 50 tons.
Raws li ib tug manufacturers Suav teb uas tau xa tawm mus rau Europe 10 xyoo, peb khiav 6 fully automated txias rolling lines, txhua tus muaj peev xwm 100,000 tons/xyoo - tag nrho peev xwm txog 600,000 tons. Peb lub lab siv ultrasonic testing (ASTM A578) los Spy cov internal defects, nrog 100% ntawm cov batches dhau ua ntej xa tawm.
Peb khaws 3,000-5,000 tons hauv peb lub warehouse, suav nrog cov qib (CS Type B, DS Type B) thiab thicknesses (0.3-3.0mm). Cov khoom lag luam tshiab hloov tshiab tiag tiag tiag ntawm peb lub vev xaib, thiab peb tuaj yeem xa FOB Shanghai hauv 48 teev rau cov khoom lag luam hauv Tshuag - tseem ceeb rau koj cov xaj xaj ceev.
Orders tshaj 100 tons tau 6% luv nqi, nrog rau dawb slitting. Peb tuaj yeem them 20% ntawm tus nqi xa khoom.
Ntawm no yog peb cov lus cog tseg: Yog tias ib qho Cold Rolled Carbon Steel Coil tsis ua tau raws li ASTM A1008 mechanical properties Los muaj defects ntau dua 0.5mm² ib m², peb yuav hais nws hauv 5 hnub thiab lawv rov qab tus nqi fre. Peb kaw tus nqi 30 hnub rau cov kev txiav txim uas tau lees paub, kom koj tsis raug kev puas tsuaj los ntawm kev zoo ntawm khw. rau ASTM A1008
