Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules of Standardization Documents"
Drafting.
This document replaces GB/T 23293-2009 "Nitride Bonded Refractory Products and Its Supporting Refractory Mud", and is compatible with GB/T 23293-2009
In comparison, the main technical changes are as follows.
a) Modified the scope of application of the standard (see Chapter 1, Chapter 1 of the.2009 edition);
b) Added the definition of refractory mortar for nitride-bound refractory products (see 3.2);
c) Added J-DGT, J-DWT and JN grades and their technical indicators (see Chapter 4, Table 1, Table 2 and Table 3);
d) Added the batch average value (μ0) and batch standard deviation estimate (σ) of the qualified quality of nitride-bound refractory products (see Table 2);
e) The chemical composition of nitride-bound refractory products and supporting refractory slurries has been added as acceptance inspection items (see 7.2.3).
