High-speed Steel Roll Displacement Control Precautions
High-speed steel is roll displacement adjustment of a critical aspect of the rolling process, its accuracy directly affects the quality of rolling convex, concave surface finish and shapes are consistent. Therefore, the high-speed steel rolling displacement control basically requires to grasp the essentials, do not neglect its importance. Here we focus on high-speed steel roll displacement control considerations.
First, the use of correct data
In the high-speed steel rolling displacement routine Checkout procedure should be clear whether the correct parameters, such as: the thickness of the material, the number of passes, pass number and other parts data information, and these parameters must match the actual product used in the rolling process.
Second, to conduct a comprehensive check of the rolling mill
Check high-speed steel roll displacement prior to operation, we should conduct a comprehensive examination of the rolling mill, including: the inspection of the machine frame, bearing, reducer, etc., should also be subjected to a comprehensive examination of the roller axis, pay attention to its support is complete and effective.
Third, pay attention to precision during installation
In the high-speed steel rolling displacement at installation time, the installer should note that the ruler mounting surface must be flat and stable, you should also pay attention when the ruler is affixed to prevent the presence of any homing error generation. The installation should be careful, it must check all parameters to ensure that the installation technique is correct.
Fourth, check endpoint clearance
High-speed steel rolling displacement adjustment involves the adjustment of the length of the interval, it is necessary to ensure that the gap size is correct, if not, can adjust the gap size.
Fifth, record the parameters
High-speed steel rolling displacement adjustment before the adjustment of the parameters must be clearly written down, including the adjustment of the next gap size, adjustments and other parameters, so that we can more clearly the adjustment process.
Sixth, pay attention to the accuracy of the readings
After the adjustment parameters, pay attention to the accuracy of when reading the gage, need to frequently calibrate the ruler and gage, to ensure that this value is correct.
Finally, increase maintenance
Once the settings completed, regular maintenance is necessary to extend the life of the device and ensure the quality of the product. Small problems in the early stages of the problem can be found and can the disabled repaired in a timely manner.
In this paper, we introduced the high-speed steel roll displacement control of several considerations, I believe you understand, not can adjust the displacement of the roller clearance, in order to ensure the yield and quality of the product, correct and timely adjustment of the clearance is particularly important.
