ã€China Aluminum Industry Network】 Each alloy has its own critical performance, within the critical performance range, the higher the quality of the ingot, the better the overall mechanical properties, the pressure required to make the product to achieve the required mechanical properties of the deformation The smaller the amount; the higher the deformation rate, the smaller the genetic influence of the ingot.
In determining the mechanical properties of an ingot, the pros and cons of obtaining and using an ingot with this property should be taken into consideration:
1) The mechanical properties of the ingot determine the properties of the ingot during hot working. The higher the plasticity of the ingot, the faster the hot processing speed allowed, the less waste, and the higher the yield.
2) The effect of the mechanical properties of the ingot on the performance of the semi-finished product increases as the degree of deformation of the ingot decreases. The genetic effects of the compound precipitated in the form of coarse, roughly dense dots and loose and non-metallic inclusions on the mechanical properties of semi-finished products are more prominent.
3) The greater the yield strength of the ingot, the more difficult it is to process, the greater the required processing power, the higher the heating temperature of the ingot, and some additional costs.
4) Obtaining ingots with great mechanical properties leads to the necessity of limiting the casting speed and the productivity of the machine.
Based on the above rules or facts, it can be considered that obtaining an ingot with high and uniform mechanical properties should be one of the general principles for establishing a continuous casting process. However, in each specific case, the necessity of obtaining ingots with higher mechanical properties should be correctly estimated, and whether the mechanical properties of the ingots can be appropriately reduced from the standpoint of improving machine productivity or other requirements.
