一、机械行业及其能源消耗的特点机械行业主要是通过对金属原材料物理形状的改变、加工、组装进而成为产品的制造行业,其生产方式基本上分为:1)离散型:是指以一个个单独的零部件组成最终成品的生产方式,比如机械装配;2)流程型:是指通过对于一些原材料的加工,使其形状或化学属性发生变化最终形成新形状或新材料的生产方式,诸如冶炼等。 First, the characteristics of the machinery industry and its energy consumption Machinery industry is mainly through the physical shape of the metal raw material changes, processing, assembly and thus become the manufacturing industry, the production methods are basically divided into: 1) discrete: refers to a Separate components form the final finished product, such as mechanical assembly; 2) Process: refers to the production of new shapes or new materials by changing the shape or chemical properties of some raw materials, such as Smelting and so on.
