The relationship between microstructures and ductility parameters, including reduction of area, elongation to failure, occurrence delamination, number turns failure in torsion, hypereutectoid pearlitic steel wires was investigated. transformed at 620 °C were successively dry-drawn drawing strains from 0.40 2.38. To examine the effects hot-dip galvanizing conditions, post-deformation annealing p...

With good mechanical properties and corrosion-resistance, galvanized coils are used in many fields nowadays, such as auto industry and household appliance industry. Because of high additional value of galvanized product, steel plants pay much more attention on how to make continuous galvanizing lines (CGL) run efficiently. In this paper, we address a scheduling problem of continuous galvanizing...

The performance of a one (OCR) and a two-compartment electrochemical reactor in the presence of a cation-exchange membrane (CEM) for the zinc recovery present in the spent pickling baths is analyzed in this paper under galvanostatic control. These solutions, which mainly contain ZnCl2 and FeCl2 in aqueous HCl media, come from the hot dip galvanizing industry. The effect of the applied current, ...

Baja AISI 1020 dalam industri perkapalan banyak digunakan sebagai pipa air laut kapal. Dilihat dari kegunaannya baja jenis ini akan mudah terkorosi jika mengaliri tanpa perlindungan apapun, hal tersebut disebabkan karena merupakan salah satu media korosif bagi baja. Tujuan dilaksanakannya penelitian untuk mengetahui pengaruh penggunaan metode pelapisan Hot Dip Galvanizing dengan variasi tempera...
