Ol i save yusim planti 'galvanized steel wire' long wok konstraksen, 'hardware', 'wire mesh', pawa na telekomyunikesen, egrikalsa na lukautim ol animal, 'highway guardrails', na wokim ol 'steel rope'. Kwaliti bilong prodak i save afektim stret sefti bilong projek, sevis laip, na reliabiliti; olsem na, ol i mas bihainim ol strongpela, wanbel, na ol kwaliti standet we ol i ken skelim long olgeta taim bilong prodaksen.
Ol samting bilong wokim 'galvanized steel wire' em i 'hot-rolled low-carbon steel rod, we ol i save wokim long ol samting olsem Q195, Q215, Q235, SAE 1006, SAE 1008, SAE 1010, na SWRCH18A. Kwaliti bilong ol 'raw material' em i nambawan samting we i save makim ol 'mechanical properties', kwaliti bilong pes, na 'zinc plating adhesion' bilong pinis prodak. Kabon konten i save afektim strong, strong, na strong bilong ain waia na ol i mas bosim gut: C Liklik o wankain olsem 0.15%, Si Liklik o wankain olsem 0.07%, Mn0.30%~0.60%, P Liklik o wankain olsem 0.035%, S o wankain olsem S o wankain olsem S. 0.035%. P na S em ol pipia nogut; sapos ol i putim planti tumas dispela inap long mekim 'brittleness' i go antap, 'draw fracture', na 'zinc plating' i no inap pas gut. Olsem na, strongpela bihainim bilong ol mak antap em i bikpela samting.
Ol samting bilong masin i save makim ol hap we ol i ken yusim Galvanized Steel Wire. Mipela i nidim wanpela strong bilong 290~420MPa, longpela bilong en i winim o wankain olsem 25%, daunim bilong eria i winim o wankain olsem 55%, na hatpela HRB 60~75. Rot bilong waia i no ken gat ol hul we i stap ples klia, i bruk bruk, o i go liklik; sapos nogat, em i save bruk taim yu droim na ol bruk long pinis prodak. Planti manmeri i gat strongpela lo long gutpela bilong 'surface' bilong 'Galvanized Steel Wire'. Ol profesenel manifakta i mas meksua olsem pes bilong en i no gat ol bruk, ol folda, ol mak, ol 'burrs', ol 'iron oxide scale' we i tik tumas, ol 'rust spot', ol mak bilong oil, na ol pipia taim ol i lusim faktori. Diamita tolerans i mas ±0.20mm, na 'ellipticity' i mas liklik o wankain olsem 60% bilong diamita tolerans. Ol 'wire rod' we i gat bikpela ros long en i tambu long wokim; sapos nogat, 'pickling' bai i no inap pinis na 'zinc layer adhesion' bai i no inap long pas gut.
As tingting bilong 'pretreatment' em long rausim 'oxide scale', 'rust', na oil, na mekim gutpela na 'activated steel wire surface' i stap gut na bai i gat gutpela 'metallurgical bond' namel long 'molten zinc' na 'steel substrate'. Nogut pretritmen taim ol i wokim Galvanized Steel Wire inap long mekim 'zinc layer' i bruk, 'plating' i no gutpela, na kala i senis.
Ol standet bilong rausim gris na rausim oil: Alkali konsentresen 5%~10%, tempereja 60~80 digri, taim bilong tritim 3~8min. Standat bilong sekim: Nogat ol mak bilong oil o saponifikesen residu long pes bilong ain waia, wara film i go het na wankain, nogat ol hul bilong surik.
Asid pikel na rausim ros kwaliti standet: Planti taim ol i save yusim haidroklorik asid pikel. Ol i mas bosim gut 'concentration', 'temperature', na taim. Hydrochloric acid konsentresen 12%~18%, tempereja rum tempereja~45 digri, taim 5~15min. Bihain long ol i bin piklim, pes bilong en i mas gat wanpela silva-grei metalik lait i stap ples klia, nogat 'oxide scale residue', na nogat 'over-corrosion. Ol i save skelim 'over-corrosion long lukluk bilong ol hul, 'hydrogen embrittlement', o blakpela long pes; sapos ol i painim, ol i mas rausim pes bilong en.
Ol gutpela standet bilong wasim wara: Bihain long 'acid pickling', yu mas wasim planti 'countercurrent'. Namba wan step em i yusim klinpela wara long rausim fri asid. Namba tu step i yusim pH we i winim o wankain olsem 4 long stopim asid long go insait long 'fluxing tank'. Standat bilong sekim: Nogat asid residu o ain sol i pas long pes.
Stretim kwaliti standet bilong tritmen: Flux em i save stap olsem 'zinc chloride' + Ammonium chloride miks solusen i save helpim long stopim 'secondary oxidation' na mekim 'zinc bath' i kamap wet. Mipela i nidim wanpela konsentresen bilong 150-250 g/L, wanpela tempereja bilong 50-70 digri, wanpela pH bilong 4.0-5.5, wanpela tritmen taim bilong 1-3 minit, wanpela draim tempereja bilong 120-200 digri, na wanpela standet taim bilong draim we i drai olgeta, i no gat wara, ol mak bilong sol, na ol 'salven stary'. Ol i mas klinim 'flux solution' oltaim long rausim 'slag'; sapos nogat, ol 'zinc slag' na 'zinc nodules' bai kamap, na dispela bai bagarapim gutpela bilong 'Galvanized Steel Wire'.
Galvanising i bruk i go long 'hot-dip galvanizing' na 'electro-galvanising, na ol kwaliti standet bilong tupela i no wankain, na dispela i mekim em i kamap wanpela bikpela samting long ol foren tred inspeksen.
Hot-dip galvanized steel wire kwaliti standet: Hot-dip galvanising i save kamapim wanpela tikpela 'zinc layer' na longpela 'corrosion resistance', bihainim ISO 1460, ASTM A641, na GB/T 20492. Ol 'raw material zinc ingots' em 99.999%, bihainim 'puzinc/T GB/T'. 470. Tempereja bilong 'zinc bath' em 440~465 digri, 'aluminium' i stap insait long en em 0.18%~0.22%, ol pipia bilong 'zinc bath' i liklik o wankain olsem 0.02% Fe, na yu no ken yusim 'recycled zinc'.
Electro-galvanised steel waia kwaliti standet: Electro-galvanised steel waia i gat gutpela pes na i gat liklik 'zinc layer', na i gutpela long ol gutpela prodak. Hevi bilong 'zinc layer' em 10~40g/m2, tiknes em 1.4~5.6μm, pes bilong en i lait na wankain, i no gat paia o tudak, na em i no gat planti 'brittleness', na dispela i mekim em i gutpela long tanim na wokim. Pasin bilong en long sakim korosen i no strong tumas olsem hot-dip galvanising, na em i no gutpela long ol ples we i gat planti korosen.
