How does the packaging steel strip manufacturer choose the slab size?
　　Answer: The following main factors and principles should be considered when selecting the size of blooming or continuous casting slabs.
　　The factors that should be considered when choosing the slab size are:
　　 (1) The blank supply capacity of the upper process;
　　 (2) Match the production capacity of the unit;
　　 (3) Can meet the product size requirements in the product outline;
　　 (4) There are more advanced technical and economic indicators.
　　The selection principle of slab size includes the selection principle of thickness, width and length.
The principle of thickness selection is:
　　 (1) Match the production capacity of heating and rough rolling, and the unit weight of the maximum unit coil width (kg/mm) does not exceed the design requirements;
　　 (2) Consider the ability to control the finishing temperature (temperature difference between head and tail);
　　(3) Excellent unit production balance ability (heating, rough rolling, finishing rolling, coiling).
The principle of width selection is:
　　 (1) Considering the unit's ability to pass the width of the plate, the general coil width Bmaxu003d(0.88-0.955) x the length of the roll body;
　　 (2) Consider the configuration of vertical rolls and the maximum lateral pressure, as well as the unit's ability to control bandwidth;
　　 (3) Consider the width series of the product.
　　 See Table 2-1 for an example of the slab width of a 1700mm unit.
The principle of length selection is:
　　 (1) Consider the width of the heating furnace and the largest outer diameter of the coil
　　 (2) Consider the allowable head and tail temperature difference of the final rolling temperature;
　　 (3) Consider the amount of cantilever related to the unit weight of the strip.
