Improvement of the 1880 Slab Sizing Press Pinch Rolls

Abstract:

The back group of the pinch rolls of the 1880 Slab Size Press are wearing away seriously in some domestic steel mill, so based on the finite element software a sizing press mode1 is established. The major reason of the back pinch rolls wearing away is the partly contact between the rolls and the “dog-bone” of the pressed slab. The work condition of the new bank group of the pinch rolls is greatly improved in the production line and the cost of production is saved.
