Specifications for copper mould plates of continuous casting
1 Scope
This standard specifies the requirements, test methods, inspection rules and marking, packaging, transportation, storage and contract (or order) contents of copper mould plates of continuous casting.
This standard is applicable to copper-chromium-zirconium alloy and copper-silver alloy plates for continuous casting and copper alloy mould plates with electroplated coatings of nickel-iron, nickel-cobalt, cobalt-nickel and nickel.

3 Requirements
3.1 Product classification
3.1.1 Classification of copper mould plates
3.1.1.1 By cross-section shape of continuous casting billets, copper mould plates of continuous casting may be classified into: copper mould plates for plate billets, copper mould plates for rectangular billets, copper mould plates for shaped billets and copper mould plates for thin plate billets, as shown in Figure 1.
3.1.1.2 By structural form (Figure 2), copper mould plates of continuous casting may be classified into: copper mould plate with wide edge on inner-arc side, copper mould plate with wide edge on outer-arc side, copper mould plates with narrow edge on left side and copper mould plates with narrow edge on right side. The copper mould plates with wide edge on inner-arc side and those with wide edge on outer-arc side may have the same structure, which are called wide edged copper mould plates; the copper mould plates with narrow edge on left side and those with narrow edge on right side may have the same structure, which are called narrow edged copper mould plates.
