针对石油钻采高压管线连接活接头生产中的问题，提出利用锻造余热直接淬火的形变热处理工艺。

In light of the problems occurred in manufacturing the high-pressure pipeline unions, the authors propose to treat the union by direct quenching through the use of the residual heat of forging.

仿真结果表明，对直接驱动的大流量、高压液压机而言，压力建立过程是直接影响压机锻造次数的关键因素之一，是高速液压机液压系统设计应考虑的问题之一。

The results show that the time of pressure building-up is a main factor affecting the forging number of press. This is a problem to take into account when designing a high-speed hydraulic press.
