阀门球体的毛胚锻造加工方法，是用于控制流体输送管道中流体流动状态，因阀门球体结构简单，安装维修方便，密封性能好，无内泄漏，体积小等优点，备受市场用户的喜爱。
The rough embryo forging processing method of the valve ball is used to control the fluid flow state in the fluid transmission pipeline. Because the valve ball has the advantages of simple structure, convenient installation and maintenance, good sealing performance, no internal leakage and small volume, it is loved by market users.
1.按球体毛坯锻打时的温度分：
1. According to the forging temperature of sphere blank:
(1)热锻:将坯料加热到一定温度再进行锻造称为热锻。
(1) Hot forging: heating the blank to a certain temperature before forging is called hot forging.
(2)冷锻:将坯料在常温下进行锻造称为冷锻。冷锻所需的锻压设备吨位较大。冷锻可以获得较高精度和强度以及较光洁表面的锻件。
(2) Cold forging: forging the blank at room temperature is called cold forging. The tonnage of forging equipment required for cold forging is large. Cold forging can obtain forgings with high precision, strength and smooth surface.
(3)温锻:坯料的加热温度小于热锻时的温度。它所需设备吨位较冷锻小，可锻制强度较高和表面较粗糙的锻件，是目前正在发展过程中的一种新工艺。
(3) Warm forging: the heating temperature of the blank is less than the temperature during hot forging. It requires less equipment tonnage than cold forging, and can forge forgings with higher strength and rough surface. It is a new process in the process of development.
2.按球体毛坯作用力分
2. Divided by sphere blank force
(1)手工锻造加工：依靠手锻工具盒人力的打击，在铁砧上将毛坯锻打成预定形状的锻件。
(1) Manual forging processing: relying on the manual blow of the manual forging tool box, forging the blank into a forging with a predetermined shape on the anvil.
(2)机器锻造：依靠锻造工具在各种锻造设备上将坯料制成锻件。机锻按所用的设备和工具不同，又可分为自由锻造、模型锻造、胎膜锻造和特种锻造四类：
(2) Machine forging: relying on forging tools to make blanks into forgings on various forging equipment. According to different equipment and tools used, machine forging can be divided into four categories: free forging, model forging, fetal membrane forging and special forging:
自由锻造:它是将加热到一定温度的金属坯料放在自由锻造设备的上下砧之间进行锻造，由操作者控制金属的变形而获得预期形状的锻件。
Free forging: it is a forging in which the metal blank heated to a certain temperature is placed between the upper and lower anvil of the free forging equipment for forging, and the operator controls the deformation of the metal to obtain the expected shape.
模型锻造：简称模锻。它是将加热到一定温度的金属坯料放到固定于模锻设备上的模具型腔内进行锻造并限制其变形，从而获得与模具型腔一致的锻件的生产方法。
Model forging: Die Forging for short. It is a production method that puts the metal blank heated to a certain temperature into the die cavity fixed on the die forging equipment for forging and limits its deformation, so as to obtain the forging consistent with the die cavity.
胎膜锻造：简称胎膜锻。它是介于自由锻和模锻之间的一种变形方式，把加热到一定温度的金属坯料，用自由锻的方法通过不固定于自由锻设备上的胎膜来获得成型的锻件。
Fetal film forging: referred to as fetal film forging. It is a deformation mode between free forging and die forging. The metal blank heated to a certain temperature is obtained by free forging through the fetal membrane not fixed on the free forging equipment.
特种锻造：它是在专用设备上或特殊模具内使金属坯料成形的一种锻造工艺方法。如精密锻造、辊锻轧制、辗环轧制、螺旋斜轧、横向轧制、挤压成形等。
Special forging: it is a forging process method for forming metal blanks on special equipment or in special molds. Such as precision forging, roll forging rolling, ring rolling, helical cross rolling, transverse rolling, extrusion forming, etc.
