INTRODUCTION OF HOT ROLLING BALL PRODUCTION LINE

The automatic hot rolling ball production line (steel balls production line) is welcomed to produce hot rolled steel balls for different size & material. High productivity,  low labor tensity, large production, easy operation, widely used for modern forging balls producing； production mechanization, the high degree of automation ； stable quality, high HRC, small HRC difference between internal and surface, high impact value, environmental protection, and energy-saving, can easily form large-scale production.

The main components:

  • Round bar deliver system
  • Induction heating system
  • Hot cutting machine ( balls over dia70mm)
  • Hot pressure machine ( balls over dia70mm) 
  • Main rolling machine 
  • Isothermal machine
  • Quenching machine
  • Tempering machine 

PRODUCING PROCESS

  •  After checking the round bars and passed qualification, put the round bars into the induction furnace to heat to a certain temperature. With the help of the heat cutting machine, the round bars were cut automatically.
  • Put the red-hot condition’s round bar into the hot pressure machine to make the semi-finished balls.
  • Put the red-hot condition’s semi-finished balls into the rolling balls machine, and form the forging balls.
  • The hot rolling balls in red-hot condition will go into the water quenching machine for quenching and then cooling at a certain time.  And then put all of them into tempering machine so that to make needed HRC.
  • After checking by the laboratory, put all qualified steel balls into plastic bags and deliver them to clients. 
  • Except for the tempering, the other production process will be done in the hot rolling balls production line.
