The MSW RMS Roll Assembly Module enables the recording and reporting of the building of roll assemblies for the mill.
Assembly data can be captured for both work rolls and backup rolls via the work roll building screen and the backup roll building screen. These screens are designed for ease of use, minimising the data entry task for the operator and therefore allowing assembly data to be quickly recorded at the end of every build job.
Details of all assembly components can be recorded to provide full traceability. Roll chock identities (including housed bearings), sledge identities and brush rig identities may all be recorded, for example. This enables mill trip data such as tonnage and meterage rolled to be recorded against all assembly components so that they can be maintained on the basis of usage in the mill rather than merely on the basis of time.
Roll assembly data is thoroughly validated upon entry. For example, roll chocks can only be entered for the correct position and side (top drive, bottom operator etc). Similarly, if the diameter difference between a pair of work rolls exceeds that which is permissible for the mill stand then a warning is displayed. This ability to generate alarms at the building stage allows problems to be highlighted before roll assemblies enter the mill.
The configurability of the RMS allows for different building procedures and alarms to be defined for alternative mills or for the alternative stands of a mill. For example, stands requiring EDT rolls can be configured to prompt the operator for entry of Post-EDT Surface Roughness data within the work roll building screen.
Packer (liner) height is automatically calculated when the building of backup rolls is recorded and can be made available to the Mill Control Computer for setting up the mill.
Reporting of roll assembly data is provided through the RMS Reporting Module and the Rollshop Explorer module. These tools let management investigate, for example, the components of any built assembly that has been used in the mill. Each assembly component can be 'drilled-down' to reveal its life-cycle data at the point it was used in the assembly. For example, the dimensions recorded during its last maintenance check, accumulated tonnage and meterage since last maintenance or last refurbishment etc. Such capabilities assist the investigating of mill problems in greater detail than ever before and the prevention of such problems in the future.
