Prime Cold Rolled Mild Steel Sheet 4 hli Thickness ASTM AISI DC02 DC03 DC05 DC06 Carbon Txias Rolled Steel Phaj

Kub dov

Kub dov siv slab (tsuas yog nruam 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 qhov kub thiab txias los ntawm laminar ntws, thiab dov rau hauv steel sawb kauj los ntawm lub coiler. Lub tshuab txias txias yog ua tiav rau hauv cov phaj steel, tiaj tus coil thiab cov khoom siv longitudinal strip los ntawm cov kab sib txawv (leveling, straightening, transverse los 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 tas mus li dov, cov khoom tiav yog dov tawv yob, vim hais tias ntawm lub txias hardening tshwm sim los ntawm tas mus li txias deformation ntawm lub dov nyuaj yob lub zog, hardness, toughness thiab yas Performance index poob, yog li cov stamping kev kawm yuav deteriorate, tsuas yog siv tau yooj yim deformation. 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 khoom nta: Vim tias nws tsis tau muab tshem tawm, nws qhov hardness yog siab heev (HRB yog ntau dua 90), kev ua haujlwm tsis zoo, tsuas tuaj yeem ua tau yooj yim kev taw qhia bending ua haujlwm tsawg dua 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 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.
