Review of the United States Refractories Industry

Factors affecting the U.S.refractories industry,such as decreasing demand,mergers ,and decreased education are discussed,along with manufacturing statistics(i.e.,annual value and product trends),indicating that the U.S.market has declined for five straight years,.Research activities have changed,with more emphasis on practical,applied projects,which have continued to produce important advances,Many challenges and opportunities remain,based on the current and future business requirements.     

SinoSteel Luoyang Institute of Refractories Research （LIRR）

Established in 1963 and once subordinate to the former Ministry of Metallurgical Industry, as one of national key scientific research institutes in China,LIRR was an integrated research institute as well as a service center for industrial technology, academy and information in refractory industry. Since 1999, LIRR has been transformed into a state-owned high-tech enterprise and become a subsidiary of SinoSteel Corporation.

Production and properties of Cr2O3 Raw Material for Refractories

There are many processes to produce Cr2O3 from chrome-ores,Different particle size ranges of Cr2O3 powder,fine pinment grade green Cr2O3 and coarse metallurgy grade black Cr2O3, are made by different processes in China,Green Cr2O3 as superfine and addition and metallurgy grade black Cr2O3 used to synthesize Cr2O3 grain can be applied to refractories.It is very difficult for high purity Cr2O3 to sinter to densification and TiO2 addition is contributed to densification of Cr2O3 sintered at high temperature,Cr2O3 grains with relative density of 91%-95% are gained by sintering Cr2O3 with TiO2 addition and electrofusing Cr2O3 raw materials.
