 PF 302

The forged steel rolls for hot mills are manufactured with well chosen quality forged steel blanks, special heat treatment is applied to make rolls in satisfactory barrel hardness and hardening depth. While good wearability is obtained, a comprehensive property of high toughness and excellent biting ability is also achieved.
This type of rolls is used in the plate (strip) mills, among the various rolls, the tube rolls is with a high quality and is rich in assortment, complete in specification and wide in application, The technical properties of FSH-10 Butt welded tube mill rolls have satisfactorily met the customer's requirement. The quality of hyperbolic straightening rolls are in the leading position at domestic market, recently the rolls and sleeves for non-ferrous casting mill have also been developed successfully.
