Sintered Spinel refractory material PROCESS OF PRODUCTION AND APPLICATION
Sintered Spinel is made of imported industrial alumina and high quality active magnesia as starting materials,sintered at super-high temperature,which is a prefered material for basic refractories and high quality castables for ladle and for con-casting slide plates due to its features of ultral-low impurity,good crystal growth and homogenized structure.
Sintered Spinel is mainly used as secondary material in middle and small ladle casting materials, high grade Spinel is large ladle casting and as the main material of large cement kiln spinel and magnesite spinel.
