Foreword

This standard was drafted in accordance with the requirements given in GB/T

1.1-2009.

This standard replaces YB/T 042-2004 "Lime for metallurgical". Compared with

YB/T 042-2004, the main technical changes are as follows:

- In clause 4.1, MODIFY the general grade of metallurgical lime, FROM

superior grade, first grade, second grade, third grade, fourth grade TO

superior grade, first grade, second grade, third grade;

- In clause 4.1, MAKE corresponding adjustments to the physical and

chemical indicators;

- In clause 4.2, MAKE corresponding adjustments to the product granularity;

- In Clause 6.1, MAKE corresponding adjustments to the inspection batch

size;

- In clause 6.2, MAKE corresponding adjustments to the sampling amount;

- In clause 7.1, MAKE corresponding adjustments to the product storage time.

This standard was proposed by the China Iron and Steel Industry Association.

This standard shall be under the jurisdiction of the National Steel

Standardization Technical Committee (TC 183).

Drafting organizations of this standard: Wuhan Iron and Steel (Group) Company,

Metallurgical Industry Information Standards Research Institute.

1 Scope

This standard specifies the classification, technical requirements, test methods,
