- The capacity of producing nickel-copper BFe10-1-1 pipe is 100,000 t/a.The line possess many advantages, such as large extrusion ratio, high efficiency, high yield and transportation by railway . 黄铜冷凝管生产线:采用了先进的工艺技术生产黄铜冷凝管,产能为6000吨/年。
- large extrusion ratio 大挤压比
- With an increase in extrusion ratio, the extend of fining grain intensify and the size of grain changes, and hence the yield strength and brinell hardness increase. 随挤压比的增大,晶粒细化程度增加;强度、硬度随挤压比的增大而增大。
- On the other hand, the surface of the sandpile is not able to resist large extrusion stress, which can be an additional criterion to describe the mechanics of sandpile avalanche. 另外,结果显示,沙堆表面也对崩塌也很敏感,表面不能承受很大的挤压(或者说张力),这个结果很类似液体的行为。
- If the extrusion ratio and the extrusion temperature were lower, there were mixed crystal and un-completed recrystallization as strip in the extruded products. 当挤压比较小以及挤压温度较低时,存在混晶组织和未完全再结晶组织,未再结晶的晶粒为长条状。
- To decrease bending and twist deformation of non-sym metry extruded sections, a new conception of local extrusion ratio and die band ratio has been set up, and also the formulas for the place of die hole on the ba sis of simulating test. 为减小非对称型材挤压的弯扭畸变,在试验研究的基础上,建立了局部挤压比、挤压带系数的概念,挤压筒中心与挤压模孔型中心相对位置的计算式。
