2. Features of Dia 100mm* Length (2m-7m) grinding steel rods for rod mill

a) Low wear, unique chemical composition. The wear resistant steel grinding rod is 1.5 to 2 times stronger than that of the rolled steel bar. Marked by excellent wear resistant property, the product can save a lot of cost for the customer.

b) High hardness of 45HRC to 55HRC, and strong toughness.It is manufactured by using the latest production method.

c) The dimension and the specification can be adjusted in accordance with the requirements of the customers.

The largely improved flexibility can lower the unnecessary waste.

d) Server for long time, economize the production cost and mitigate the labor intensity of the workers.

Moreover, it eliminates the need for stopping the rod mill to add the new steel grinding rod every day, which is conducive to largely enhancing the productivity.

3. Different steel specifications ccording to the clients's requirements.
