NORTON VA 1213 Dry Vibratable in 50lb bag
VA 1213 is a fused alumina based dry vibratable refractory utilizing a spinel bond designed for coreless induction furnaces melting steel. Utilizing high purity raw materials and a proprietary grain size distribution VA 1213 rams to a dense low porosity monolithic lining. After sintering, VA 1213 exhibits positive permanent expansion which helps to seal the hot face while providing a dense, unsintered safety back up.
The alumina-magnesia spinel bond has high resistance to chemical attack by slags. It has a relatively high maturing temperature and is sintered through the use of a meltout form.
