ABSTRACT:
This invention relates to cement-free refractories exhibiting high green strength, improved corrosion resistance, and improved magnesium oxide hydration resistance useful as refractory castables for steel ladles, slag contact areas, ladle sidewalls and bottoms, and the like and as precast refractory shapes, such as well blocks, nest blocks, and the like. More particularly, this invention is directed hydraulically-bonded monolithic refractories containing a calcium oxide-free binder comprised of a hydratable alumina source and magnesium oxide and which exhibit high green strength, improved corrosion resistance, improved magnesium oxide hydration resistance, and controllable work and set times.
