High Quality Txias Rolled Carbon Mild Steel Phaj Sheet carbon steel daim hlau chaw tsim tshuaj paus carbon steel phaj

Kub dov

Kub dov siv slab (tsuas yog nruam casting billet) ua raw khoom thiab ua rau sawb hlau los ntawm roughing zeb thiab xov zeb tom qab cua sov.Qhov kub steel sawb los ntawm qhov kawg kawg zeb yog txias rau lub teeb kub los ntawm laminar txaus, thiab yog dov rau hauv steel sawb kauj los ntawm lub coiler.Lub tshuab txias txias yog ua tiav rau hauv steel phaj, tiaj tus coil thiab longitudinal strip cov khoom los ntawm cov kab sib txawv (leveling, straightening, transverse or longitudinal cutting, inspection, weighing, packaging and marking, etc.) raws li kev xav tau ntawm cov neeg siv khoom sib txawv.Txhawm rau muab nws yooj yim dua, ib lub slab ntawm cov hlau yog rhuab (hom liab, kub daim hlau uas kub hnyiab hauv TV), dov ob peb zaug, trimmed, thiab ncaj rau hauv lub phaj steel.Qhov no yog hu ua kub dov.

 Txias dov

Txias dov: nrog kub dov steel kauj raws li raw khoom, tom qab pickling kom tshem tawm cov oxide daim tawv nqaij rau txias nruam dov, cov khoom tiav yog dov tawv yob, vim hais tias txias hardening tshwm sim los ntawm tas mus li txias deformation ntawm dov tawv yob lub zog, hardness. , toughness thiab yas Performance index poob, yog li cov stamping kev ua tau zoo yuav deteriorate, tsuas yog siv tau yooj yim deformation qhov chaw.Cov yob tuaj yeem siv los ua cov khoom siv raw hauv kub dip galvanizing cog vim tias kub dip galvanizing units yog nruab nrog cov kab annealing.Rolled nyuaj coil qhov hnyav yog feem ntau 6 ~ 13.5 tons, steel kauj ntawm chav tsev kub, kub dov pickling coil nruam dov.Sab hauv txoj kab uas hla yog 610mm.

Cov yam ntxwv ntawm cov khoom: Vim tias nws tsis tau annealed, nws hardness yog siab heev (HRB yog ntau dua 90), lub machining kev ua tau zoo heev, tsuas yog yooj yim directional dabtsi yog khoov ua hauj lwm tsawg tshaj li 90 degrees (perpendicular rau cov kev taw qhia ntawm coiling).

Txhawm rau muab nws yooj yim, txias dov yog ua tiav thiab dov los ntawm lub hauv paus ntawm kub dov phaj thiab yob.Feem ntau hais lus, nws yog txheej txheem kub dov - pickling - txias dov.

Txias dov yog ua tiav los ntawm kub dov phaj ntawm qhov kub thiab txias, txawm hais tias lub phaj hlau yuav raug cua sov thaum lub sijhawm ua haujlwm vim yog dov, tab sis tseem hu ua txias dov.Raws li qhov tshwm sim ntawm kev kub dov los ntawm kev ua kom txias deformation ntawm txias dov, cov khoom siv kho tshuab tsis zoo, lub hardness siab dhau lawm.Yuav tsum tau annealed los kho nws cov khoom siv kho tshuab, tsis yog annealed hu ua dov tawv yob.Rolled nyuaj yob feem ntau yog siv los ua tsis muaj dabtsi yog khoov, ncab cov khoom.
