3 Terms and Definitions

The terms and definitions defined in GB/T 18930 and the following apply to this document. 3.1 The product is made of bauxite with different alumina contents as the main raw material, which is synthesized through batching, homogenization, fine grinding, molding, high temperature calcination and other processes. Alumina-silica refractory clinker with uniform distribution, uniform structure and stable performance.

4 Brand

According to the chemical composition of alumina, bauxite-based refractory homogeneous materials are divided into eleven grades, namely FNJ-90, FNJ-88, FNJ-85, FNJ-83, FNJ-80, FNJ-70A, FNJ-70B, FNJ-60A, FNJ-60B, FNJ-50A, FNJ-50B. The "F", "N" and "J" in the brand name respectively stand for "bauxite". The first Chinese characters of "base", "refractory" and "homogeneous material" are the pinyin initials. The numbers are the mass fractions of aluminum oxide. A and B are the grades. Differences in iron content.
