PROCESS

1)High quality

 

High quality comes from every working procedure for the control . Grinding ball have no great

differences in appearance, but in the actual effect of grinding efficiency is different, this is because

the raw material, heat treatment process, equipment automation level and other factors can lead to

the steel ball steel ball lapping efficiency differences, and ultimately affect the user cost of grinding .

Every working procedure we always follow the details of the accused, by providing more wear-

resisting of grinding ball to help customers to reduce the cost of grinding.

 

1 >   Raw material contrast

 

Ordinary company :  directly using the scrap or various steel grades production, traditional little

involvement in the high rate of grinding materials research and development.

 

Iraeta : have a deep cooperation with The Chinese academy of sciences and steel plant , according

to different industry standard have in-depth research and development, developed raw material

with higher grinding performance.

2 > Heat treatment of contrast

 

Ordinary company : Usually use pure water cooling quenching with insulation barrels of tempering ,

the heat treatment method is easy to cause uneven hardness, the lack of resilience, steel ball high

broken rate in practical use.


Iraeta : Closed cooling tower for effective control of quenching temperature within the scope of the

standard, the composite heat treatment technology can improve the internal organization of steel ball,

the ball while guarantee the hardness have sufficient toughness are less likely to break.

 3 > Production craft contrast

 

Ordinary company : degree of automation is less than manual intervention, there is no guarantee

that the stability of each batch steel ball.


Iraeta : Fully automated production lines, greatly reduced the manual intervention, to ensure the

stability of different batch grinding steel ball quality.

 4 >  Quality control of contrast

 

Ordinary company : Have less testing instrument , and the lack of objective testing standards.

 

Iraeta : Through ISO17025 laboratory accreditation service international standard certification,

the quality control system though audit for many times, passed nearly 30 different international

industry certificatio.
