铸造金属的熔化与浇注，铸造金属（铸造合金）主要有各类铸铁、铸钢和铸造有色金属及合金；
(3) Casting treatment
and inspection, casting treatment includes removal of core and casting
surface foreign bodies, cutting out the pouring gate, shovel grinding
burrs and seams and other protrusions, as well as heat treatment,
shaping, anti-rust treatment and roughing.
③铸件处理和检验，铸件处理包括清除型芯和铸件表面异物、切除浇冒口、铲磨毛刺和披缝等凸出物以及热处理、整形、防锈处理和粗加工等。
The
casting process can be divided into three basic parts, namely, casting
metal preparation, mold preparation and casting treatment.
铸造工艺可分为三个基本部分，即铸造金属准备、铸型准备和铸件处理。
Cast
metal refers to the metal material used for casting castings in casting
production, it is a metal element as the main component, and add other
metal or non-metallic elements and composed of alloys, customary known
as casting alloys, mainly cast iron, cast steel and cast nonferrous
alloys.
铸造金属是指铸造生产中用于浇注铸件的金属材料，它是以一种金属元素为主要成分，并加入其他金属或非金属元素而组成的合金，习惯上称为铸造合金，主要有铸铁、铸钢和铸造有色合金。
Metal
smelting is not only a simple melting, but also a smelting process, so
that the metal poured into the mold, in terms of temperature, chemical
composition and purity are expected to meet the requirements.
金属熔炼不仅仅是单纯的熔化，还包括冶炼过程，使浇进铸型的金属，在温度、化学成分和纯净度方面都符合预期要求。
To
this end, in the smelting process to control the quality of the various
inspection tests, liquid metal can be allowed to pour after reaching
the specified indicators.
为此，在熔炼过程中要进行以控制质量为目的的各种检查测试，液态金属在达到各项规定指标后方能允许浇注。
Sometimes,
in order to meet higher requirements, the metal liquid is also treated
outside the furnace after the oven, such as desulfurization, vacuum
degassing, refining outside the furnace, inoculation or metamorphic
treatment.
有时，为了达到更高要求，金属液在出炉后还要经炉外处理，如脱硫、真空脱气、炉外精炼、孕育或变质处理等。
The
commonly used equipment for melting metal are cupola, electric arc
furnace, induction furnace, resistance furnace, reverberatory furnace,
etc.
熔炼金属常用的设备有冲天炉、电弧炉、感应炉、电阻炉、反射炉等。
