Long-term performance of pot hardware in continuous galvanizing lines
Preliminary comparative wearing tests were conducted on wearguard bearing system against CF3M (casting version of 316L steel), with tungsten carbide laser clad coating, at 30% and 50% production line tension. Tests were also conducted on Stellite 6 against Tribaloy T 400 at 50% production line …

Developing the design of road going welded structures with special considerations for hot-dip galvanizing
… The area of highest interest is hot-dip galvanizing. The influence of temperature on steel has long been studied and several sources have found, or otherwise mathematical expressions were derived which describe the relationships between mechanical properties and temperature. Understanding …

Selective oxidation and segregation in commercial steels and model alloys : (tools for improving the surface wettability by liquid Zn during hot dip galvanizing
To improve a wettability of annealed high strength steels and model alloys by Zn bath, two processes were applied to modify the surface: selective oxidation during annealing in 5% H2/N2 at 820°C at dew points -60, -30 and 0°C on HSS (DP 500, Ti-IF and TiNb-IF), and preoxidation in air at 700°C with …

ATOMISTIC SIMULATION AND FIRST PRINCIPLES CALCULATION OF INTERFACIAL ENERGETICS OF GALVANIZED ADVANCED HIGH STRENGTH STEELS
… i.e., Si, Mn, in AHSSs raises concerns of how galvanizing processes for these steels will be affected. Galvanizing is a cost-effective processing method widely used in industry to improve the corrosion resistance of steels. For the galvanizing processes of AHSSs, Si and Mn can be selectively …

Zinc pot bearing material wear rate as a function of contact pressure and velocity
There are currently over 50 galvanizing lines in operation in the United States producing approximately 50 million tons per year of galvanized sheet. Frequently zinc-pot hardware fails which causes production delay, resulting in an economic loss. It takes approximately 3 hours to change the …

Catastrophic Progress: A Queer Materialist Analysis of the 2023 Trans/Bud Light Controversy
… the conservative right was swift and extreme, galvanizing protests against Anheuser-Busch InBev and resulting in a massive loss in sales that is still discussed in news and pop culture circles today. The event offers unique analytic value, particularly through the nexus of queer and materialist …

Transnation: Chilean Television Infrastructure and Policy as National Space, 1969--1996
… shift occurred in the logics shaping that space, galvanizing opposition to Pinochet and catalyzing a transition toward civilian rule. During the early 1990s, privatization, foreign investment, and technological renovation dramatically transformed Chilean television once again. In the wake of these …

Ferric chloride from crude copperas
… steel is “pickled” in sulfuric acid previous to galvanizing, and in ore refining where sulfuric acid is used to remove undesirable impurities consisting chiefly of iron materials. One of the chief uses of copperas is as a coagulant in water treatment. Crude copperas, as produced, does not meet …
