GB/T 33018-2025Energy-saving technical specification for carbon products enterprises (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part

1.Structure and Drafting Rules of Standardization Documents". Drafting. This document supersedes GB/T 33018.1-2016 "Technical Specifications for Energy Conservation in Carbon Enterprises Part

1.Impregnation" and GB/T 33018.2- 2016 "Technical Specification for Energy Conservation in Carbon Enterprises Part

2.Calcination Kilns" and GB/T 33018.3-2016 "Technical Specification for Energy Conservation in Carbon Enterprises Part

3.Calcination Kilns" Part. Machining. This document is based on GB/T 33018.1-2016, and integrates GB/T 33018.2-2016 and GB/T 33018.3-2016. Content. Compared with documents such as GB/T 33018.1-2016, apart from structural adjustments and editorial changes, the main technical changes are as follows:

a) The scope has been changed, adding molding and graphitization processes (see Chapter 1, Chapter 1 of the.2016 edition);

b) The term and definition of "immersion tank" have been removed, and the term and definition of "molding process" have been added (see Chapter 3, Chapter 3 of the.2016 edition);

c) The principle of impregnation has been removed (see Chapter 4 in the.2016 edition);

d) Basic requirements have been added, and common technical requirements for each process have been integrated (see Chapter 4, Chapter 5 of the.2016 edition);

e) Added energy-saving technical measures for major processes, integrating energy-saving technical requirements, energy-saving measures, energy-saving operation, and energy-saving maintenance for each process. (See Chapter 5, Chapter 6 in the.2016 edition);

f) The technical requirements for energy management have been revised (see Chapter 6,

6.3 of the.2016 edition);

g) Increased testing and control requirements (see 7.2, 7.4~7.9);

h) Safety and environmental protection requirements have been removed (see Chapter 8 of the.2016 edition);

1 Scope

GB/T 33018-2025 is the Chinese national standard covering energy in a carbon and graphite works - the calcining, mixing, baking and graphitisation, the last of which consumes an enormous amount of electricity, and the heat recovery and process control that reduce it. It replaces GB/T 33018.1-2016. It was issued on 2 December 2025 and has been in force since 1 July 2026, replacing GB/T 33018.1-2016. The document is under the responsibility of the China Iron and Steel Association. This page is published from the official record of the 2025 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.
