SUMMARY:Soft rolling control for weld-point in tandem cold mill
DESCRIPTION:Following the recent trend of weight reduction in car industry, producing high quality cold-rolled UHSS(Ultra High-Strength Steel) strip becomes important.

Strip breakage in Tandem Cold Mill(TCM) is one of the biggest problems in cold rolling.

When producing UHSS, strip breakage occurs more frequently.

When a plate break occurs, the line stops. And productivity decreases.

And safety issues can also arise during maintenance work.

So we need methods to prevent strip breakage.

Most of the strip breakage in TCM occurs near the weld-point between the coils.

In general, strip breakage is caused by over rolling force at the weld-point.

So in this paper, we propose Soft Rolling Control near the weld-point between the coils.

Soft Rolling means a rolling method that makes the weld-point thicker.

We propose two methods to makes the weld-point thicker.

They are a method using the predicted rolling force and a method using the mass flow theory.
