Kawat baja galvanis ditarik saka 45 #, 65 #, 70 # lan baja struktural karbon berkualitas tinggi liyane, banjur galvanis (electro galvanis utawa galvanis panas).
Kawat baja galvanis minangka jinis kawat baja karbon galvanis ing permukaan kanthi plating panas utawa elektroplating.Sifat-sifat kasebut padha karo kawat baja tempered sing lurus.Bisa digunakake minangka tulangan prestressed unbonded, nanging kudu galvanis paling 200 ~ 300g saben kothak meter.Asring digunakake minangka tali kawat paralel kanggo jembatan kabel-tetep (saliyane, lengen kabel fleksibel uga digunakake minangka lapisan njaba lapisan pelindung).
properti fisik
Lumahing kawat baja galvanis kudu alus lan resik tanpa retak, knot, eri, bekas lan teyeng.Lapisan galvanis seragam, kanthi adhesi sing kuat, tahan karat sing kuat, ketangguhan lan elastisitas sing apik.Kekuwatan tensile kudu antarane 900 Mpa lan 2200 Mpa (diameteripun kabel Φ 0.2mm- Φ 4.4 mm), jumlah twists (Φ 0.5mm) kanggo luwih saka 20 kaping lan bola mlengkung luwih saka 13 kaping.
Ketebalan lapisan galvanis hot-dip yaiku 250g / m.Ing resistance karat saka kabel baja wis apik banget.
rencana
Kawat baja galvanis utamane digunakake ing tanduran omah kaca, peternakan breeding, kemasan katun, manufaktur spring lan tali kawat.Iki ditrapake kanggo struktur rekayasa kanthi kahanan lingkungan sing ora apik kayata jembatan kabel lan tangki limbah.
Proses nggambar
Proses Electroplating sadurunge nggambar: Kanggo nambah kinerja kawat baja galvanis, proses nggambar kawat baja dadi produk rampung sawise annealing timbal lan galvanizing diarani electroplating sadurunge nggambar.Aliran proses khas yaiku: kawat baja - quenching timbal - galvanizing - drawing - kawat baja rampung.Antarane cara drawing saka kabel baja galvanis, proses plating pisanan lan banjur drawing proses paling cendhak, kang bisa digunakake kanggo panas galvanizing utawa elektro galvanizing lan banjur drawing.Sifat mekanik kawat baja galvanis panas sawise digambar luwih apik tinimbang kawat baja sawise digambar.Loro-lorone bisa entuk lapisan seng lancip lan seragam, ngurangi konsumsi seng lan ngurangi beban saka baris galvanizing.
Proses gambar sawise plating penengah: proses drawing sawise plating penengah yaiku: kawat baja - quenching timbal - drawing utami - seng plating - drawing secondary - kawat baja rampung.Fitur saka plating medium sawise drawing iku kabel baja timbal quenched wis galvanis sawise drawing sapisan, lan banjur produk rampung digambar kaping pindho.Galvanizing antarane rong gambar, supaya disebut electroplating medium,.Lapisan seng saka kawat baja diprodhuksi dening electroplating medium lan banjur drawing luwih kenthel saka sing diprodhuksi dening electroplating lan banjur drawing.The total compressibility (saka timbal quenching kanggo produk rampung) saka hot-dip galvanis kawat baja sawise electroplating lan drawing luwih dhuwur tinimbang kabel baja sawise electroplating lan drawing.
Proses gambar kawat plating campuran: kanggo ngasilake kawat baja galvanis kanthi kekuatan ultra-dhuwur (3000 N / mm2), proses "gambar kawat plating campuran" kudu diadopsi.Alur proses khas minangka nderek: timbal quenching - drawing utami - pre galvanizing - drawing secondary - galvanizing final - drawing tersier (drawing garing) - rampung drawing tank kawat baja.Proses ing ndhuwur bisa ngasilake kawat baja galvanis ultra-dhuwur kanthi kandungan karbon 0,93-0,97%, diameter 0,26mm lan kekuatan 3921N / mm2.Sajrone proses drawing, lapisan seng nglindhungi lan lubricates lumahing kabel baja, lan kabel baja ora break sak proses drawing.
