Low-water castable materials based on periclase have been developed for very large precast shapes, such as electric furnace runners and bottom pour ingots

Refractory castables based on magnesia-alumina spinel have been developed for steel ladle lining materials. One of the main advantages of spinel formation is the reduction in slag penetration and consequent reduction in corrosion [ILLUSTRATION FOR FIGURE 1 OMITTED]. The slag, which contains iron, calcium and silica penetrates into the refractory with the iron becoming trapped in a spinel/alumina solid solution. The calcia ...
