What is grinding ball heat treatment
After grinding balls are manufactured in casting ball metal mold or automatic grinding ball molding line, the next most important process is heat treatment. Grinding ball heat treatment includes quenching and tempering. Grinding ball heat treatment is used to quenching and tempering for casting balls
Why grinding ball need to heat treatment furnace
For casting steel ball, the most important is the balls quality. According to the casting production technology, most users are using two ways to control grinding balls quality. First, they must control well the chemical composition, this step is very easy to come true. Second, the most important is by heat treatment furnace.
The main purpose of grinding ball heat treatment furnace is to improve grinding balls quality, change its internal performance and improve its harness.
Quenching process is cooling grinding balls at a rapid rate from a predetermined high temperature. This process is important as it is key in addressing the main challenge of manufacturing steel balls of high quality.
Tempering process is done to relieve the metal of any residual stresses that might be sent up during the quenching process of grinding balls.
How Does Cast Grinding Ball Works
Grinding ball heat treatment furnace is driven by hydraulic and the running is stable and reliable .It is mainly made of by heating furnace body, quenching system, loading balls basket turning machine, pushing machine, turning machine, hydraulic system and electric control system. It automatically heat treatment of grinding balls and change grinding balls' metallographic structure to improve the hardness the whole quality of grinding balls by fiber cotton, PLC, intelligent temperature controller, other detection devices and heated by resistance components.
The Main Characteristic Of Heat Treatment Machine For Grinding Balls
The inner furnace is fiber cotton. Compared with brick, the energy saving will be better 35%-40%.
It has 10cm from the bottom of the furnace to the plate of the furnace. It can automatic collect oxide skin. This can avoid short cricuit.
The furnace is equipped PLC and man machine interface control. It is very easy operation.
The temperature is uniform, which makes sure the quality of the balls
