Preface
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 29741-2013 "Safety Production Specifications for Aluminum Electrolysis". Compared with GB 29741-2013, except for the structural adjustment and editing
In addition to the functional changes, the main technical changes are as follows.
--- Added terms such as "aluminum electrolysis", "roasting", "anode effect", "electrolytic cell overhaul", "ingot" and their definitions (see Chapter 3);
--- Changed the safety requirements for site selection, plant layout and buildings (structures) (see Chapter 5,.2013 edition, 3.1.1, 3.1.2,
3.1.3, 3.1.4);
--- Changed the safety requirements for aluminum electrolysis (see 6.3, 4.1 of the.2013 edition);
--- Added safety requirements for electrolytic cell overhaul (see 6.4);
--- Added safety requirements for anode assembly (see 6.5);
--- Changed the safety requirements for ingots (see 6.6, 4.3 of the.2013 edition);
--- Changed the safety requirements for flue gas cleaning (see 6.7, 4.2 of.2013);
--- Added safety requirements for flue gas desulfurization (see 6.8);
--- Changed the safety requirements for transportation (see 6.9, 5.2 of the.2013 edition);
--- Changed the safety requirements for power systems (see 6.10, 5.3 of the.2013 edition);
--- Deleted the content of environment and health (see 5.4 of the.2013 edition);
--- Deleted the risk assessment content (see 5.5 of the.2013 edition).
