Continuous Pre-forming — With the continuous pre-forming method

Continuous Pre-forming — With the continuous pre-forming method, the forging is given a defined pre-shape in a single forming movement. Some of the traditionally used pre-forming units are hydraulic or mechanical presses as well as cross rolls. The continuous process offers the advantage, especia... Read More

The main disadvantages of water as quenching and cooling medium for forgings are:

1、in the typical part of the austenitic isothermal transition diagram, i.e., about 500-600℃, the water is in the steam film stage, and the cooling speed is not fast enough, which often leads to the "soft point" formed by uneven cooling and insufficient cooling speed of forging.In the martensitic...

Zero heat preservation, quenching and normalizing forgings

In the heat treatment of forging, due to the large power of the heating furnace and long insulation time, the energy consumption is huge in the whole process, in a long period of time, how to save energy in the heat treatment of forging has been a difficult problem. The so-called "zero insulation... Read More
