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...Read more -
Sealing principle and characteristics of flange
The sealing problem of flat welded flange has always been a hot issue related to the production cost or economic benefit of enterprises, so the sealing principle of flat welded flange has been improved and improved.However, the main design shortcoming of flat welded flange is that it cannot preve...Read more -
How many types of forging are there?
According to the forging temperature, it can be divided into hot forging, warm forging and cold forging.According to the forming mechanism, forging can be divided into free forging, die forging, rolling ring and special forging. 1. Open Die forging Refers to the machining method of forging with a...Read more -
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
