This standard replaces GB/T 4223-2004 "scrap steel." Compared with GB/T 4223-2004, the main technical content changes as follows. --- The original standard of "high quality scrap iron" and "ordinary scrap iron" be amended to "Class I scrap iron" and "Class II scrap iron" (see 4.1.1,.2004 edition 4.1.1); --- Increased the classification of scrap iron smelting, increased from 4 categories of the original standard to 5 types of scrap iron (see 4.1.2.1,.2004 edition 4.1.2.1); --- Increased the classification of scrap smelting, increased from the original standard of 5 categories for the eight types of scrap (see 4.2.3.1,.2004 edition of 4.2.3.1); --- Modify the smelting scrap dimensions and weight requirements, to further clarify the definition of a typical example (see 4.2.3.1.1,2004 Version 4.2.3.1.1); --- Added "package (briquetting) unpacking test" method (see 6.2.8); --- Increase the "crushing pile weight test method" (see 6.2.9); --- In the certificate of transport and quality, the "import of scrap iron accompanied by radioactive examination certificate" be amended to read "scrap steel to be attached Qualified information on radiological tests (see 8.2,.2004 edition 8.2); --- Modify the smelting alloy scrap steel group, from 6 steel 46 steel group, adjusted to 8 steel 49 steel group (see Appendix A, 2004 edition of Appendix B). This standard is proposed by China Iron and Steel Association. This standard by the National Standardization Technical Committee pig iron and ferroalloy (SAC/TC318) centralized.
