Problems solved by technology

[0009] Therefore, it must be operated in a particularly dirty environment. In order to adjust the steady rest, manual intervention requires a long period of time, which considerably affects the total production cost of the grinding machine.
[0010] Furthermore, this condition implies further limitations to the use of steady rests for automatic positioning, since the steady rests will be subject to very severe wear, requiring frequent cleaning and maintenance operations due to the environment in which the steady rests operate
[0011] To reduce residue and deposits in the motion area of ​​the steady rest, masking and / or cleaning devices can be utilized, however, they are costly and make manual positioning more convenient

Abstract

Positioning and blocking device (20) for steady rests (10) comprising a substantially flat carriage (21) provided with translation means (23) and blocking means (22) characterised in that said blocking means are magnetic.

Description

technical field [0001] The present invention relates to a device and method for positioning and locking steady rests for rolling mill cylinders on a grinding mill and a grinding machine employing the device. Background technique [0002] Grinding machines for rolling mill cylinders are large pieces of equipment used in steel mills to restore the surface features and structural integrity of rolls used in rolling stands, in order to obtain a long service life and high quality of the thin steel sheets produced. [0003] Typically, such mills have a non-destructive control system for identifying and detecting defects such as different forms of surface or subsurface cracks, burns, pores, etc., which can affect both the quality of the rolled product and the cylinder life. [0004] General work, especially with very slender cylindrical rolls, prepares the cylinder to be supported by a device called a steady rest, which ensures that the cylinder is supported with sufficient rigidit...
