29、e the same preparatory treatment in the furnace before the casting operation 3.3 cast quantity of products cast simultaneously from the same heat NOTEThe different pieces of a cast may have different dimensions. 3.4 top butt end of the unsawn rolling ingot corresponding to the end of the cast 3.5 bo
30、ttom butt end of the unsawn rolling ingot corresponding to the start of the cast 3.6 top end end of a sawn rolling ingot corresponding to the end of the cast 3.7 bottom end end of a sawn rolling ingot corresponding to the start of the cast 3.8 edge one of the narrow faces (plane or of a specific geo
31、metry) of the rolling ingot, parallel to the casting axis 3.9 rolling face one of the wide faces of the rolling ingot, parallel to the casting axis 3.10 corner junction of a rolling face with an edge 4 Orders or callings for tenders The order or tender shall define the product required and shall con
32、tain the following information: a) the form of the product (rolling ingot); b) the designation of the aluminium and aluminium alloy according to EN 573-1 and EN 573-2 (or the customer alloy designation after agreement between supplier and purchaser). Tighter limits may be specified as required; c) w
33、hether as cast or homogenized. The homogenizing parameters should be agreed between the customer and the producer; d) the number of this European Standard; e) the dimensions and shape of the product: 1) nominal thickness; 2) nominal width; 3) nominal length and tolerance if different from standard;

All dimensions shall be expressed in millimetres. f) sawing code (see 5.7.4); g) whether rolling ingots are to be
35、 supplied scalped or not; h) whether the rolling ingots will be scalped or not before hot rolling; i) end use (e.g. foil, packaging) (see 5.1); j) quantity: 1) mass (in metric tonnes) or number of pieces; 2) quantity tolerances if required. k) any requirements for inspection documents (see 7); l) an
36、y additional requirements agreed between supplier and purchaser (see 7). 5 Requirements 5.1 Production and manufacturing processes The product requirements as formulated in this clause normally are not sufficient for rolling ingots to meet the customers requirements for rolled products. Therefore, t
37、he customer shall give the producer full details concerning the end use requirements so the manufacturing conditions of the producer may best be adjusted to fulfill the requirements. It is recommended that trial quantities be produced to confirm that the end use requirements are met. It is also reco
38、mmended that the customer asks the producer to advise of any significant change in the manufacturing processes which may affect the quality of the final product. It is recommended that a quality assurance system be implemented as described in EN 29000 and EN 29004. 5.2 Aluminium alloys The main alum
39、inium alloys used for rolling ingots are given in EN 573-4. 5.3 Chemical composition The chemical composition of the ingots shall conform to the compositions specified in EN 573-3. It is recommended that tighter composition limits than those given in EN 573-3 be agreed between customer and producer
40、as required. Control of alkali metals is recommended: sodium and calcium for magnesium alloys; lithium for foil end use alloys. It is recommended that the hydrogen level should not exceed 0,15 ml per 100 g of aluminium. The analysis method will be defined by agreement between supplier and purchaser.
41、 5.4 Surface and internal quality Rolling ingots shall: a) be free of casting surface defects, protruding metal, handling marks, oil, dirt and corrosion; b) be free of inclusions, porosity, shrinkage cavities and cracks; c) have a suitable metallurgical structure (e.g. grain size, shell zone depth,
42、fir-tree structure); to a standard agreed between customer and producer to be suitable for rolling, after scalping or not as required, and subsequent processing. 5.5 Tolerances on dimensions 5.5.1 Cross section The shape of the cross section is left to the discretion of the customer, who shall give
43、the supplier a dimensional drawing. 5.5.2 Thickness The thickness is measured on both sides of the ingot at a distance of 100 mm from the edges. The tolerance on the thickness thus measured is 5 mm excluding (see Figure 1): a distance from the bottom butt of the unsawn rolling ingot of 0,8 times the
44、 nominal thickness (distance measured before sawing, if any); NOTEFor ingots more than 2 m wide, the distance is equal to the thickness. a distance from the bottom end of the sawn rolling ingot of 0,5 times the nominal thickness. The tolerance on thickness in the zones defined above and measured at
45、the centre of the cross-section is: 4 % of the nominal thickness for sawn ingots; to be agreed between the customer and the producer for unsawn ingots. The difference between the thinnest and the thickest parts of the sawn ingot measured anywhere on the ingot at a distance greater than 100 mm from t
46、he edges shall not exceed 5 % of the nominal thickness. 5.5.3 Width The width is measured overall. The tolerance on width isexcluding a distance from the bottom butt of the rolling ingot of 0,8 times the nominal thickness (ingot with unsawn butt) or 0,5 times the nominal thickness (ingots with sawn

The toler
48、ance on length is: a) 25 mm for sawn ingots; b) 50 mm for unsawn ingots; unless otherwise stated in the order or calling for tenders. 5.6 Tolerances of form 5.6.1 Lateral deflection The lateral deflection is the deflection measured along an edge in the casting direction, at the middle of the edge. T
49、he maximum permissible deflection on the length of the rolling ingot is 6 mm (see Figure 2). 5.6.2 Longitudinal deflection The longitudinal deflection is the deflection measured along a rolling face in the casting direction, at 100 mm from one corner. The maximum permissible deflection on the length of the ingot is 6 mm (see Figure 2). 5.6.3 Diagonal deflection The diagonal deflection is the deflection measured along a diagonal line of a rolling face. It qualifies the twist of the rolling ingot. The max
