    Abstract The present study aims to analyze the corrosion mechanism of Al 2 O 3 -SiC-C castables for blast furnace main trough. The anti-oxidation and corrosion properties of the castable caused by slag were studied with residual lining investigation and microstructure analysis. A rapid recognition of grain distribution ingredients and

    If slag is saturated with refractory oxide then J = 0. Naturally to minimize rate of dissolution it is necessary to minimize (C sC m). For example with increasing MgO content in the slag the corrosion of the periclase phase in Mag-Chrome refractories will decrease.

    Dec 01 2014 · The most noticeable improvement in monolithic refractory is low cement/low moisture castable development . In the new monolithic refractories technology low and ultra-low cement castables have an ever-decreasing amount of high alumina cement and its corresponding water for placement. Low cement and low water improves high temperature properties.

    Studies of the coal slag s individual oxide components showed CaO reacts with the chrome refractory to form a low melting Ca(CrO2)2. FeO reacts with the sesquioxide to form a interface layer of (Cr Fe) 3O4 spinel phase. Results of this study now make it possible to design studies for improving corrosion resistance to increase refractory life.

  • Corrosion of high alumina and near stoichiometric spinels

    Feb 01 2003 · Dissolution of alumina-rich spinel aggregates in iron-containing silicate slag was studied using grain corrosion tests. High alumina spinels (AR90 90 Al 2 O 3) dissolve indirectly while dissolution of near stoichiometric (AR78 78 Al 2 O 3) spinel is entirely direct.This behaviour arises because higher alumina spinels can accommodate more cations from the slag due to the greater

    The corrosion of refractories in contact with high temperature aluminum-magnesium alloys leads to contamination of the Al-Mg alloy products by solid impurities from degraded refractories. Where both the spinel and corundum phases form in the refractories cracks are generated and propagated by diffusion of molten Al-Mg resulting in severe corrosion.
