New Mill Design and Installations

Mill Installation

Because the equipment on large mills is heavy, the customer does not usually have the means or ability to install it. Normally an outside company is hired for the mill erection. Here the Sendzimir service department can give instructions and certain advice on any and all of the mechanical aspects.

Sendzimir's engineers know the subtle details of installing a Sendzimir mill - details that even the mill builder may not know. Certain components must be assembled in specific ways, paying careful attention to details. If the assembly is not done properly, problems may arise further down the road.

This is one of the instances where the expertise of the Sendzimir Service department comes in.

Sendzimir's mill installation service can include supervision of an entire installation or periodic advisory visits. Usually, Sendzimir's services are called for when an installation is nearing completion. The service engineers will review crucial questions with the builders and management to ascertain that nothing has been overlooked, and will run classes for the foreman, operators, helpers, and roll grinding operators.

Stage 1 - Installation Supervision

When an installation is close to completion, the main work of our service department will normally commence. Basic overview of our duties is as follows:

• Go over a few crucial questions with builders and management to see that certain things have not been overlooked and see that the most obvious aspects of everything are in order.
• Run classes for the foreman, operators, helpers and roll grinding operators.
• Explain the difference between small work roll operations and 4-High operation (if applicable) so that the major differences of operation are well understood.
• Explain in general the mill, its parts and their function such as:
  • Screwdown
  • Rolls and Roll Crowning Techniques
  • Taper Grinding on the First Intermediate Rolls
  • Crown Adjustment Manipulation
  • Side Eccentric Settings
  • Hydraulics, Coolant System, etc.

Stage 2 - Training on the mill rolling strip

• Explain the pass reduction logic
• Explain total reduction capabilities
• Discuss shape and factors relative to shape.
• Discuss surface luster and factors relative to surface luster.
• Teach the science of successfully rolling with high speed, etc.

At the mill, we check and properly set hydraulics for screwdown, winders, coil lifters, carriages, wipers, pressure boards, side guides, coolant system etc.

Used Equipment

Sometimes the customer will purchase a used mill and will ask TSINC for help to put the mill into operation. The help may consist of very much the same as described above on a new mill. The difference will be to check more carefully all the parts, to see if they are in a useable condition. and if they are within good tolerances. If certain parts are in rough shape we would advise whether or not to replace and or rebuild them. We could also advise where to go for such services.
