Four reference samples in Fe 430 B, uncoated or Zn coated (deposited by hot dipping, cold spraying,
electrogalvanizing), with layers of equivalent thickness to the above-mentioned hybrid organic-inorganic coatings, were used for comparative purposes.
The
electrogalvanizing and hot-dip galvanizing of steel panels were carried out under industrial subcontracting.
(Spectrum 7b), it shows that both EZG panels were subjected to the
electrogalvanizing process as stated in their products' data sheet.
Although the possibility of rust is more likely at the edges of the hood than at its center, the amount of
electrogalvanizing is the same right across the surface.
"Once you hot dip that product you change the strength quality in the hot roll and you lose all the advantages of your high strength, so
electrogalvanizing is the way to go."
Zinc has much in common with tin in that several solution options exist and are used - acid chloride and sulphate for
electrogalvanizing, and alkaline zincate and cyanide for rack and barrel plating.
In what follows, I describe the process involved in restructuring a finishing process at each plant: a bar mill at Indiana Harbor Works and an
electrogalvanizing line at Gary Works.
Sumitomo Metal Industries Ltd., a major Japanese steelmaker, announced Thursday it has terminated its
electrogalvanizing joint venture with LTV Corp., a leading U.S.
Steel, a unit of Pittsburgh-based USX Corp., has invested $1.1 billion in its flagship Gary Works since 1981 to take advantage of new technology, including pulverized coal injection and a double-sided
electrogalvanizing line.
is used for galvanizing and
electrogalvanizing. A new nickel-zinc, hot-dip galvanizing process, patented by Cominco Ltd., is gaining increased industry acceptance.
Access to funds on such a scale encouraged a huge increase in investment, targeted mostly at facility modernization and at capacity expansions in relatively sophisticated processes such as continuous annealing and
electrogalvanizing.
The most recent model introduced by Durco's Valve Division is the BTV-2000 butterfly valve designed for handling harsh chemicals such as chlorinated brine,
electrogalvanizing solutions, and bleaches.
