3) Changed the definitions of the two terms, surfacing roll and continuous casting compound roll, and their English counterparts (see 4.8, 4.15, 1995). version 3.1.6, 3.1.4);

4) Changed the definitions of the terms powder metallurgy roll and spray deposition roll (see 4.12, 4.16, 3.1.3, 1995 edition 3.1.5).

c) The material classification part changes as follows:

1) The terms carbon cast steel roll and semi-chilled ductile iron roll are deleted (see 3.1.1a and g of the 1995 edition);

2) Changed alloy cast steel rolls, cast semi-steel rolls, graphite steel rolls, high chromium steel rolls, infinite chilled cast iron rolls, high chromium rolls Iron rolls, pearlitic ductile iron rolls, bainitic ductile iron rolls, forged steel rolls, forged semi-steel rolls, forged white rolls Definitions of 10 terms for iron rolls (see 5.1.1, 5.1.2, 5.1.3, 5.1.4, 5.2.2, 5.2.3, 5.2.4, 5.2.5, 5.3, 5.3.5, 3.1.1b, c, d, e, h, k, i, j, 3.1.2a, b, c) of the 1995 edition;

3) Changed the English equivalents of the two terms: cast semi-steel roll and forged white iron roll (see 5.1.2, 5.3.2, 1995 edition) 3.1.1c, 3.1.2c);

4) Added cast steel rolls, alloy tool steel rolls, high-speed steel rolls, high-carbon high-speed steel rolls, cast iron rolls, alloy ductile cast rolls Definitions of 10 terms such as iron rolls, forged alloy steel rolls, forged high-speed steel rolls, and forged semi-high-speed steel rolls (see 5.1, 5.1.5, 5.1.6, 5.1.7, 5.2, 5.2.2.6, 5.3.1, 5.3.2, 5.3.3).

d) The changes in the rolling process and configuration classification are as follows:

1) Added hot-rolled strip rolls, vertical rolls, pattern rolls, billet rolls, hot-rolled section steel rolls, universal rolling mill horizontal rolls, and universal rolling mill vertical rolls. Rolls, horizontal roll rings, vertical roll rings, piercer rolls, stop mandrel rolling mill rolls, three-roll stop mandrel rolling mill rolling Rolls, Axel Rolls, Sizer Rolls, Tension Reducer Rolls, Pilgrim Rolls, Welded Steel Pipe Rolls, Squeeze Rolls, Cold Bending 21 terms and definitions of section steel rolls, cast rolls and Sendzimir rolls (see 6.1, 6.2, 6.8, 6.12, 6.13, 6.14, 6.15, 6.16, 6.17, 6.20, 6.21, 6.22, 6.23, 6.24, 6.25, 6.26, 6.27, 6.28, 6.29, 6.30, 6.31);
