Describe the cold rolling processing of steel processing methods
Dec 09, 2017

In the steel processing, we can use different methods to complete. One of them is called cold rolling method. According to the current practical application, which can also be subdivided into cold-rolled, cold drawn and cold drawn, cold-formed, cold extrusion and other methods. In general, the so-called cold rolling method refers to the hot rolled steel recrystallization temperature below the continued processing.

 

As a result, cold rolled steel can be obtained. In contrast, using this method for steel processing, can further improve the mechanical properties of steel, and get a high dimensional accuracy and a certain finish products. In practice, we often use the cold rolling method to produce cold rolled steel, cold rolled steel tubes and cold rolled steel bars. In the processing of cold-rolled steel, the equipment used are two-roll mill, four-roll reversible mill, multi-roll reversing mill and tandem cold mill.

 

Usually, during the process of this kind of steel processing, although there are only two working rolls in the four-roll and multi-roll rolling mills, any working roll actually has one or even a plurality of large-diameter bearings Roll support, can effectively prevent the work roll deflection.

 

So we can use these devices to process some of the larger width, and the smaller thickness of the plate. In the processing of cold-rolled steel pipe and other steel processing, the main equipment used is two-roll cycle cold rolling mill and multi-roll cold rolling pipe machine. In the processing of cold-rolled steel is the use of Y-type three-roll mill production.

 

For now, in many workplaces, many users will choose the cold-formed method for the steel processing requirements. This method has two major advantages: First, cold-formed steel section is light weight, bearing a large, which can replace the use of hot-rolled steel, you can save the metal; Second, you can produce hot-rolled can not produce a variety of special thin, Extra wide and section shape complex steel.
