“…After careful observation, it is found that steel can be protected effectively from oxidation even at temperature of 1250 0 C with the help of glass coating. At this temperature, to keep the growth rate of Cr2O3 slower proper supply of Cr from steel is required which can be achieved at this temperature by reducing the diffusion of oxygen from air which is ultimately possible because of presence of glass coating [20]. [20] At such a high temperature the layer of Cr2O3 got cracked and pores are formed.…”

A protective glass- based coating of N-15 and N-25 glass was deposited on the Crofer steel by slurry method and its effect on 7500C-8500C has been studied. Oxidation behavior of steel at high temperature of 12500C was also investigated. Interface study of N-25 glass &Crofer steel and N-15 glass &Crofer steel has been done and found that coating of N-15 glass on the steel is more smooth and effective to prevent the surface of steel from corrosion.Structural study of different type of glass has also been done. Bare steel sample as well as coated steel sample was taken for the study of their isothermal oxidation which shows that the glass coating could prevent the corrosion and improve the quality of steel surface for practical application.This corrosion resistant effect takes place because a thin layer of molten glass is formed on the surface of steel at high temperature. This layer then acts as a diffusion barrier. This coating of glass and steel is cost effective, hence have wide application in many infrastructural construction where corrosion is a big challenge. It is also very useful in marine conditions where steel is most likely to be corroded be sea water.

In the slab reheating process, the temperature distribution of walking beam furnace is critical for the temperature of slab, as well as the subsequent hot rolling. Besides, this process is dynamic, nonlinear, and time varying due to coupling with complex physical and chemical reactions. In this paper, we focus on an operation optimization problem of tuning furnace temperature to optimize the slab reheating process, which considers the reheating quality and production cost. For this purpose, we develop a novel operation optimization method. Specifically, first, from the view of mechanism, a heat transmit model based on the heat-exchange of slab and furnace, an energy consumption function, and especially, an oxidation loss function are established. Therefore, incorporating the mechanism models, we build an optimization model to minimize temperature deviation of slab, energy consumption, and oxidation loss to describe our problem. Then, based on the features of the problem, we propose a modified differential evolution algorithm, which includes a space contraction scheme, a new self-adaptive parameter strategy, and a new mutation operator. Finally, to evaluate the performance of our method, extensive numerical experiments are implemented by comparing it with other well-known evolutionary algorithms based on practical data. The experimental results demonstrate the effectiveness of proposed operation optimization method on solving our problem.
