Since the dawn of time, mankind has been shaping things from metal. 最早的记载是“天赐之石”, referring to meteorites falling from the sky containing iron, 金属及金属加工的核心成分.
流星从天而降
大约9,000 BC, records acknowledge one of man’s first metal accomplishments, 一种由金属加工而成的牛形黄金装饰品. 从铜器时代开始, 到青铜时代, 直到铁器时代, man has been perfecting the craft of metalworking and metal casting. 在这段时间里, 金属被用来制作碗的形状, 井盖, 管道, 煎锅, 工具, 和武器.
在工业时代, 主要是在18世纪及以后, 对机加工部件和复杂机械部件的需求使金属铸造达到了新的高度. 零件不再仅仅是金属冲压或机械加工;
需要金属铸造!
铸造厂 are the very establishments that transform metal into metals castings. They engage in the pouring of metal into molds or dies, to form castings. Essentially, any hard metal that can be melted, can be cast.
There are various types of foundries involved in metal casting:
这些铸造厂之间的核心区别在于是否使用黑色金属或有色金属. 含铁金属是指含铁金属,而不含铁的有色金属. 这是一个重要的区别,因为危险和伤害的性质可能不同.
铁,灰铁和钢. 黑色铸造厂是最常见的铸造铸造厂. 下面是一些由这些金属制成的产品:
是的,一个普通的发动机缸体
能认出牌子的加十分
Engine blocks, 机 tool frames, pipe-适合tings, pumps, and valves
Guns, rifles, Aerospace, medical equipment, and high impact wear products.
Ferrous 铸造厂 have a high number of recordable injury cases, with 6.每100名员工中就有1名. 钢铁铸造厂的比例最高,约为6.每100名员工就有9名.
一分钱主要是由锌制成的
Silver, Platinum, Gold, Copper, Nickle Titanium, Aluminum, Tin, and Zinc
有色金属铸造厂大约有6个.每100名员工中有3起可记录的案件,铝铸造厂大约有7起.可记录案件8件.
取决于所执行的强制转换的复杂性, 铸造厂将遵循类似的铸造工艺.
下面是铸造过程:
该模式提供了所需部件或最终产品的精确复制品.
变速箱模式的例子
准备模具,将液态金属倒入刚性框架中,形成铸件. 制芯功能包括将芯插入模具中,形成铸件的内部. Behind metalworking, this part of a foundry employs the most workers.
型芯制造
熔化的金属被倒入模具中.
浇注熔融金属
Once the molten liquid has been poured, the mold cools rapidly.
在落砂过程中,金属从模具中取出. During 清洁 and Shot Blasting, focus is placed on the removal of sand.
铸件经过热处理, 多余的金属被修剪和移除, 铸件抛光,成品检验.
