Study on Properties of Re-Bonded Magnesium Zirconium Refractory Materials and Materials Application
Nineteen eighties, the sintering zone of cement rotary kiln and transition belt use main magnesia chrome brick because of its excellent performance, but the Cr6+ is carcinogenicity, which causes great harm to the air, water pollution, animal or human. Therefore, new basic refractory material of free of chrome began to be developed. This test, the raw material is made up of fused magnesite particles (particle size 0 to 3 mm), fine fused magnesite powder with the size less than 200 meshes and fine fused magnesia-zirconia’s powder with the size less than 320 meshes, polyvinyl alcohol and calcium lignosulfonate liquor being used as the combiner. This paper discusses the effect of sinter temperature on sinter character of products.
