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.
