Improvement of the 1880 Slab Sizing Press Pinch Rolls

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.
