Hot rolling Forged grinding balls for cement 90mm

• Hot rolling Forged grinding balls for cement 90mm and 80mm
• Produce all kinds of hot-rolled ball-grinding ball according to the forged (rolling) steel ball ferrous metallurgy industry standard (YB/T 091-2005). The diameter of steel ball is Φ25-Φ125mm. The blank of rolling ball-grinding ball is the hot-rolled round steel bar with various chemical components, and the diameter is equal to the nominal diameter of steel ball. The production technology process of hot-rolled steel ball is as follows:
  1. After the inspection, the round steel bar is cut into the steel ball blank according to the specified lengths.
  2. Before the rolling, the steel ball blank is heated to the appropriate temperature in continuous heating furnace.
  3. The billet under the red and hot state is sent into the ball rolling mill, and moves forward between the two rollers with special hole patterns, and it is made into the steel ball. Each ball rolling mill can produce 60-360 steel balls per minute.
  4. The rolled steel ball under the red and hot state is immediately sent into the online heat treatment equipment designed by our factory for quenching - tempering heat treatment, so that the steel balls can get the high and even hardness.
  5. The qualified products are sent to the finished goods warehouse, packaged and delivered to the customers.
