求翻译：通过锻造能消除金属在冶炼过程中产生的铸态疏松等缺陷，优化微观组织结构，同时由于保存了完整的金属流线，锻件的机械性能一般优于同样材料的铸件。相关机械中负载高、工作条件严峻的重要零件，除形状较简单的可用轧制的板材、型材或焊接件外，多采用锻件。是什么意思？

By forging can eliminate the metal smelting process produces as-cast defects such as loose, optimized microstructure, and because to save a complete line of metal flow, forging better than the same general mechanical properties of casting materials. Related to mechanical load in the high, harsh work

Through forging can eliminate metal to metal casting patterns emerge in the course of the defects, such as osteoporosis, optimization and micro-organizational structure, and at the same time preserving the integrity of the metal roof, and forgings of mechanical properties of materials in the same ge

Can eliminate the metal loosely through forging the cast condition which produces in the smelting process and so on the flaws, the optimization microscopic organizational structure, because simultaneously has preserved the integrity metal streamline, the forging mechanical property surpasses the sam

By forging can eliminate metal produced in the refining process of casting defects such as loose, optimizing microstructure, and thanks to save the complete set of metal flow line, forgings, castings for mechanical performance than the same material. High mechanical load, operating conditions tough

Defect of loosening etc. of casting the attitude of ones that produce through can dispel the metal to forge in the course of smeltinging, optimize the micro institutional framework because well preserved at the same time the metal streamline, the mechanical performance of the forging is su
