Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 2275-2007 "magnesia brick and magnesia-alumina brick", compared with GB/T 2275-2007, the main technical changes are as follows.
--- Added terms and definitions (see Chapter 3);
--- Removed M-93, M-87, MLZ-80A, MLZ-80B, MLJ-70 grades, added MLZ-80, MLJ-90, MLJ-85
(See.2007 version 4.1);
--- Modify the magnesia brick, magnesia-alumina brick and magnesia spinel brick chemical composition, apparent porosity, compressive strength at room temperature, load softening temperature, etc.
Indicators (see tables 2 and 3,.2007 edition tables 2 and 3);
--- Increased the quality of qualified batch average and standard deviation (see Table 2 and Table 3);
--- Modify the sampling and acceptance rules for acceptance rules (see 7.2,.2007 version 6.2).
