| 1. | Carbon and high - strength electric resistance forge - welded steel structural shapes
碳和高强度电阻锻焊钢结构型材 |
| 2. | Therefore , the two schemes on the forge - weld hbbb are designed and trial - manufactured in the works
为此，设计和试制完成了两种方案的锻焊组合结构抱轴箱体。 |
| 3. | Under the condition that the existing technology in the works ca n ' t be heightened in a short period , the forge - weld hbbb is an efficient way
在工厂现有工艺水平短期内不能有效提高的情况下，采用锻焊组合结构设计是一种有效方法。 |
| 4. | Design improvement is in three stages partial , geometrical stress concentration improvement , pure casting technology improvement and a forge - weld box body design
设计改进分三个阶段，即局部几何性应力集中改进、提高铸造质量的纯工艺改进和锻焊组合结构抱轴箱体的设计。 |
| 5. | Abstract : the first china - made forge - welded hot wall hydrogenation reactor has safely operated for 10 years and the equipment is found to be in good condition of integrity after several inspections in service
文摘:我国自行研制的首台国产化锻焊结构热壁加氢反应器已安全运行10年，此间经几次在役检验，设备状况完好。 |
| 6. | Put forward is the future plan on the improvement of the forge - weld hbbb , which is helped to research and design of the hbbb for the ss7 - type electric locomotive and other electric - driving locomotives in the future
提出了锻焊抱轴箱体攻关工作的进一步设想，对今后韶山7型电力机车抱轴箱体的进一步攻关及其它电传动机车抱轴箱体的设计和研究，有一定的借鉴作用。 |
