若因温度和变形程度选择不当而得到粗大晶粒时，可利用热处理相变细化晶粒***，但对于热处理中不发生相变的钢种，如奥氏体钢，就必须在锻造过程中获得细小而均匀的晶粒***，因此对这样的材料在锻造时须加倍注意。

If the temperature and degree of deformation and improper selection of coarse grains， the grain refinement phase change heat treatment， but for the steel phase transition does not occur in the heat treatment， such as austenitic steel，锻造， it must be in the forging process h***e fine and uniform grains， so this kind of material in the forging must pay more attention to.

低塑性拔长时，应注意选择合适的送进比，送进比太小时，变形集中在上下部，锻造报价，中心都锻不透，并沿轴向产生拉锻造应关于锻件的一些基本知识力，导致内部横向裂纹产生。在镦粗时，常用软衬垫镦粗或叠镦（用于锻薄饼形零件），以改善变形的不均匀性，圣霖锻造生产，防止产生表面裂纹。

When low plasticity is pulled out， attention should be paid to selecting suitable delivery ratio， sending too much time， deformation on the upper and lower parts， and the center can not be built， and forging along the axial direction should be related to some basic knowledge of forging， resulting in the occurrence of internal transverse cracks. In the upsetting， commonly used soft liner (for upsetting or folding upsetting forging thin pancake， uneven parts) to improve the deformation， prevent the generation of cracks on the surface.

锻造设备是指在锻造加工中用于成形和分离的机械设备。锻造设备包括成形用的锻锤、机械压力机、液压机、螺旋压力机和平锻机，锻造规格，以及锻造操作机、开卷机、矫正机、剪切机、等辅助设备。

Forging equipment is the mechanical equipment for forming and separating in forging. Forging equipment includes forging hammer， mechanical press， hydraulic press， screw press， forging machine， forging machine， coiler， straightening machine， shearing machine， and other auxiliary equipment.
