Foreword
This Standard revises and combines "Continuous Casting Square and Rectangular
Blank" (YB/T 2011-1983) and "Continuous Casting Square and Rectangular Blank of
Quality Carbon Structure Steels and Alloy Steels" (YB/T 154-1999).
This Standard replaces "Continuous Casting Square and Rectangular Blank" (YB/T
2011-1983) and "Continuous Casting Square and Rectangular Blank of Quality
Carbon Structure Steels and Alloy Steels" (YB/T 154-1999).
Compared with YB/T 2011-1983 and YB/T 154-1999, this Standard has the following
main changes.
- Steel classification in application scope is in accordance with GB/T 13304-1991;
- Chapter 3 "order contents" was added;
- The side length of continuous casting square and rectangular blank was
expanded to 380 mm;
- Table 2 "Figure of Continuous Casting Square and Rectangular Blank Shape"
was added;
- The permissible deviation of oblique cutting was adjusted;
- The specification of weight was added;
- The specification of Furnace No. division was cancelled;
- Casting content was adjusted;
- Surface quality content was modified and adjusted.
This Standard was proposed by China Iron and Steel Association.
This Standard is under the jurisdiction of China Steel Standardization Technical
Committee.

3 Definitions
For the purpose of this Standard, the following terms and definitions apply.
3.1 Continuous Casting Square Blank
Continuous casting blank shall be poured by molten steel of the same trademark. If
molten steel of different trademarks are adopted, the intermediate blank shall be
judged according to actual constituents.
6.3 Cropping and End Cropping Quantity
The head of newly-poured continuous casting blank and the end at the end of pouring
shall be provided with enough cropping length so as to ensure that the continuous
casting blank is free from shrinkage cavity.
6.4 Macrostructure
For continuous casting blank of high-quality non-alloy steel, special-quality non-alloy
steel and alloy steel, its macrostructure evaluation shall comply with YB/T 153. The
qualification grade shall be determined through negotiation between the Supplier and
the Purchaser. If the Supplier can guarantee the qualified macrostructure, inspection
may not be conducted.
6.5 Surface Quality
6.5.1 The surface of continuous casting blank shall be free from any observable,
halved joint, skull patch, scab and inclusion.
6.5.2 Common-quality non-alloy steel and low alloy steel shall be free from any
cracks whose depth is greater than 2mm; high-quality non-alloy steel and
special-quality non-alloy steel and alloy steel shall be free from any cracks whose
depth is greater than 1mm.
6.5.3 Common-quality non-alloy steel and low alloy steel shall be free from scratch,
indentation, air hole, wrinkle, cold splash, bump, concave and horizontal chatter mark
whose depth or height is greater than 3mm.
6.5.4 High-quality non-alloy steel and special-quality non-alloy steel and alloy steel
shall be free from scratch, indentation, air hole, wrinkle, cold splash, bump, concave
and horizontal chatter mark whose depth or height is greater than 2mm.
6.5.5 Cross-section of continuous casting blank shall be free from any shrinkage
cavity, subsurface bubble and cracks which affect the normal use.
6.5.6 Any above-mentioned defects or the defects beyond the specification on the
surface of continuous casting blank shall be removed. The removal width shall be no
less than 6 times of the depth and the length shall be no less than 10 times of the
depth. The defective position shall be round and smooth and free from corner angle
after renovation. The renovation depth on single side shall be no greater than 8% of
the side length of continuous casting blank; the sum of removal depth on opposite
sides shall be no greater than 12% of the thickness. The removal depth shall be
counted from actual size.
blank length. The measuring positions shall beyond the shear deformation and
defective area.
8.3.2 Length
It refers to the length from the center line of the side of continuous casting blank to the
both ends.
8.3.3 Bulgin......
