This paper proposes a new practical synthesis model for coating weight control and robust design method of feedback controller in galvanizing process. The model combines both long term and short term model. Long term model have a function of classification, averaging and learning based on real measured data. Short term model is differential model based on linear change of inputs and outputs. A ...

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...

in hot dip galvanizing, several parameters such as chemical composition of coating bath, immersion time and surface roughness of specimens could affect microstructure and properties of coating. in this article, the effect of aluminum content, immersion time and surface roughness on structure and properties of alloy layers have been investigated. specimens of low carbon silicon-free steel with d...

This scientific paper aims to determine the optimal economic roughness of galvanized surfaces by studying influence turning surface on quality galvanizing. The thickness zinc layer, its corrosion resistance, and precision parts were also examined. S235J0 steel samples processed using a operation obtain different values. Three galvanizing technologies, galvanic galvanizing, hot dip with centrifu...

THE REACTION between liquid zinc and steel, such as occurs during hot-dip galvanizing, shows some unusual kinetic features which as yet have not found a completely satisfactory explanation. The upon recent results from the in our laboratory. The main kinetic features (a) For silicon-free steels the purpose of this note is to present a mechanism based literature and some preliminary experiments ...

This paper describes the results of an industrial pollution prevention pilot project in Nebraska. The goal of the project is to demonstrate that through proper management and operating practices, that industrial pollution can effectively be reduced significantly. The net effect of this pollution prevention program is to improve the economic worth of the industry by lowering expenditures on poll...
