Technical Information
Combined skin pass mill and tension leveler technology
By combining the skin pass mill with the tension leveler, our greatest specialty, the skin pass mill can fulfill the role of improving mechanical properties and improving surface texture, and the tension leveler can improve plate flatness, thereby achieving an efficient division of roles. When the devices are combined, careful attention must be given when determining the positioning of the front, rear, and center bridle rolls, the number of rolls, and the motor capacity, and when proposing an operation method. JP Steel Plantech has a track record of delivering 45 combined skin pass mill and tension leveler systems, and has the ability to propose the optimum solutions to our customers.
Inline stainless steel skin pass mill technology
In recent years, because of the advantages of simplifying processing with offline skin pass mills and high-tension skin pass mill rolling, it has been a common practice to install skin pass mills on the exit side of stainless steel APL/BAL.
In the case of stainless steel in particular, materials and rolls are easily damaged, so it is necessary to move the skin pass mill past welded points without causing damage during operation.
To achieve this, JP Steel Plantech utilizes its technology to move items past welded points during operation, and have a significant track record of delivery.
Bridle roll mechanical drive technology enabling high-precision elongation control
This drive mechanism utilizes differential gear reduction and 2 motors (main motor and elongation motor) to provide elongation control which has a degree of precision between 30 and 50 times that of an individual drive.
The precision of the rotational speed of motors has improved recently, but this technology is being used in production lines that require stable elongation control.
