Also the extrusion pressure is not affected by length of the billet in the extrusion press since friction is not involved.
可见，缸体内的坯料保持静止，没有产生摩擦力，挤压力也不会受坯料长度影响。For the same size of billet and finished shape, the total effective strain of ring increases with increasing feed speed.
同样尺寸的坯料和成品，芯辊进给速度越大，内层的累积等效变形越大；However, the heat conductivity of the sheath material has little effects on the temperature field, stress field and load.
研究还表明包套材料导热系数对坯料温度场、应力场和载荷的影响较小。Two collar blanks therefore have to be fed simultaneously to the cigarette blocks to be packaged simultaneously.
必须将两个领圈坯料同时送入同时包装的香烟组中。Due to its slanted end surfaces, a sheared round blank often becomes elliptic in shape after an upset forging process.
由于剪切坯料端面偏斜，拍扁时压成椭圆形，此文称此现象为镦偏。Made of shaping Polytetrafluoethylene Resin into blank by moulding in ordinary temperature, through high heat sintering, then rotary cut .
用聚四氟乙烯烧树脂在常温下用模压法制成坯料，经高温烧结后旋切而成。by the sintering, obtain the densification law of powder sintering process for the molybdenum billet.
由烧结实验研究，得出烧结工艺对钼粉坯料致密化的影响规律；The results show that the drawing formality of round corner rectangular blank is better than that of other blank shapes.
结果表明：使用矩形圆角坯料比其他坯料的成形性能好。Blank: self-made or after processing, the material used for ceramic green body.
坯料：自制或经过加工后，用于陶瓷坯体的物料。
