Khoom Description
Cov txheej txheem tsim khoom ntawm DX53D + Z galvanized steel kauj feem ntau suav nrog cov kauj ruam hauv qab no:
Kev npaj steel coil: Xaiv qhov tsim nyog txias-kuav los tiag nyuaj steel kauj ua raw khoom. Lub thickness ntawm steel kauj yog feem ntau nyob rau hauv ib tug tej yam ntau yam, xws li 0.2mm mus rau 6.0mm. Nws yuav tsum tau ua raws li cov kev cai muaj feem xyuam, xws li muaj ib feem ntawm cov ntsiab lus xws li carbon, silicon, manganese, phosphorus, thiab sulfur.
Uncoiling thiab welding: Uncoil lub txias-kuav los tiag nyuaj steel kauj siv lub uncoiler. Tom qab ntawd, ua cov kev kho mob taub hau thiab tail. Tom qab ntawd, siv lub tshuab tsis siv neeg seam welder los txuas cov hlau strip steel rau txoj hlua khi hlau. Qhov no ua kom tsis tu ncua ntau lawm.
Kev tu qhov chaw: Ntxuav lub ntsej muag ntawm cov hlau nplaum kom tshem tawm cov impurities, roj stains, thiab oxides. Qhov no tuaj yeem ua tiav los ntawm txoj kev xws li pickling lossis mechanical tu. Lub hom phiaj yog los xyuas kom meej qhov chaw huv si kom zoo dua adhesion ntawm zinc txheej.
Annealing: Anneal steel sawb nyob rau hauv lub cub tawg. Annealing pab kom muag cov hlau, txhim kho nws cov formability, thiab tshem tawm cov kev ntxhov siab sab hauv. Lub annealing kub thiab lub sij hawm yog ua tib zoo tswj kom ua tiav cov khoom xav tau.
Galvanizing: Raus lub annealed steel sawb nyob rau hauv ib tug molten zinc da dej. Cov zinc adheres rau saum npoo ntawm cov hlau sawb, tsim cov txheej tiv thaiv. Lub thickness ntawm zinc txheej tuaj yeem tswj tau los ntawm kev hloov kho yam xws li lub sijhawm immersion thiab zinc da dej kub.
Txias thiab passivation: Txias lub galvanized steel sawb mus rau chav tsev kub. Tom qab ntawd, siv cov kev kho mob passivation los txhim kho corrosion kuj ntawm zinc txheej. Passivation tuaj yeem cuam tshuam nrog kev siv tshuaj lom neeg los yog txheej rau saum npoo ntawm cov hlau.
Kev tshuaj xyuas thiab ntim khoom: Tshawb xyuas cov galvanized steel kauj rau qhov zoo thiab qhov tsis xws luag. Xyuas kom nws ua tau raws li cov qauv tsim nyog. Thaum kawg, ntim cov hlau kauj siv cov khoom ntim tsim nyog los tiv thaiv nws thaum thauj thiab khaws cia.
Cov txheej txheem tsim khoom no ua rau muaj qhov zoo tshaj plaws DX53D + Z galvanized steel kauj nrog zoo corrosion kuj, formability, thiab durability, haum rau ntau yam kev siv hauv kev lag luam xws li kev tsim kho, tsheb, thiab kev tsim khoom.
