浦项钢铁公司将取自 30 0 t钢包的内壁、出钢口及钢包底部的熔铸耐火材料切成薄片试样 ,然后通过 X射线衍射和电子显微镜观察对其抗渣性进行了研究。研究表明 ,用 Mg O耐火砖与 Al2 O3 - Mg O熔铸耐火材料砌筑的钢包具有优异的粘接性。渗透到钢包壁中并粘附在壁上的熔渣形成了? Pohang Iron and Steel Company will be taken from the inner wall of 30 t ladle, tapping hole and the bottom of the ladle cast refractory cut into thin pieces of samples, and then by X-ray diffraction and electron microscopy observation of its slag resistance. The research shows that the ladle with MgO refractory brick and Al2 O3 - MgO cast refractory masonry has excellent adhesiveness. Is the slag that penetrates into the ladle wall and adheres to the wall?
