The work is aimed at characterizing the properties of slag obtained from CaO-CaF₂- TiO₂-SiO₂ based coatings developed for welding the offshore structures. Extreme vertices methodology was used to formulate coating compositions. Iron ore waste red ochre has been used as source of iron in the coating. The slag has been characterized for thermal stability, density, specific heat, enthalpy of reaction, thermal conductivity behavior, and thermal diffusivity. Welding slag was also structurally analyzed for different phases and bonds. Silicate ion (SiO₄⁴⁻) has been found to influence all the slag properties significantly. Effect of coating constituents has been studied using regression analysis. Mineral constituents and their interactions were found to have influential role on thermo-physical, chemical and structural behavior of slags.

该工作旨在表征由为焊接海上结构而开发的基于CaO-CaF ₂ -TiO ₂ -SiO ₂的涂层获得的炉渣性能。使用极端顶点方法来配制涂料组合物。铁矿石废红o石已被用作涂层中的铁源。炉渣的特征在于热稳定性，密度，比热，反应焓，热导行为和热扩散率。还对焊渣的不同相和键进行了结构分析。硅酸根离子（SiO ₄ ⁴⁻已经发现）明显地影响所有炉渣性能。已经使用回归分析研究了涂料成分的作用。发现矿物质成分及其相互作用对炉渣的热物理，化学和结构行为具有影响作用。
