GB/T 17105-2024Classification of aluminum-silicon dense shaped refractory products (English PDF)

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 for standardization documents" Drafting:

This document replaces GB/T 17105-2008 "Classification of Aluminum-Silicon System Dense Shaped Refractory Products": Compared with GB/T 17105-2008, in addition to structural adjustments and editorial changes, the main technical changes are as follows:

a) Added terms and definitions (see Chapter 3);

b) The classification basis, product types and groups, raw material types, raw material characteristics, names and descriptions of combination forms have been changed (see Chapter 4, Chapter 3 of the:2008 edition);

c) The chemical analysis requirements have been changed (see 4.2, 3:2 of the:2008 edition);

d) The description of nomenclature has been changed (see Chapter 5, Chapter 4 of the:2008 edition):

This document is modified to adopt ISO 10081-1:2003 "Classification of dense shaped refractory products Part 1: Aluminium-silicon series":

This document has made the following structural adjustments compared to ISO 10081-1:2003:

--- Added Chapter 2 "Normative References";

--- Added Chapter 3 "Terms and Definitions";

---4:2 corresponds to 2:2 and 2:3 in ISO 10081-1:2003:

The technical differences between this document and ISO 10081-1:2003 and their reasons are as follows:

--- Added normative references to GB/T 18930 in Chapter 3;

---4:1a) corresponds to 2:1a) and 2:1b) in ISO 10081-1:2003, making the content more coherent;

---4:2 adds applicable national standards GB/T 6900, GB/T 6901, GB/T 21114 to improve operability and adapt to our Technical conditions of the country;

--- Changed the definition of ceramic bonding in 4:5a) to match the definition of "ceramic bonding" in ISO 836:2001 (GB/T 18930-2020) Unite:

The following editorial changes were made to this document:

--- To coordinate with the existing standards, the name of the standard is changed to "Classification of Aluminum-Silicon Dense Shaped Refractory Products":
