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.
The main drafters of this standard: Mo Ying, Hu Bo, Wei Wenquan, Wan
Yuanyuan, You Daoming, Cai Jiming, Bai Hanfang, Qiu Jinhui, Wang Jiangwei.
This standard replaces the standard previously issued as follows:
- YB/T 042-1993, YB/T 042-2004.

6.2.1.1 Sampling amount
For continuous discharging production, take about 5 kg of sample every 2 h; for
intermittent discharging production, take about 5 kg of sample for each
discharging 5 kg of sample. Half of the 5 kg sample is sent for inspection; the
other half is used as backup sample.
