Product introduction:Grinding balls is cut wire shot, the wire cutting growth degree and equal diameter cylinder and steel cut wire shot before grinding, remove the edges and corners that served the ball.
Grinding balls is cut wire shot, the wire cutting growth degree and equal diameter cylinder and steel cut wire shot before grinding, remove the edges and corners that served the ball. Such products at the same time has the advantages of cast steel shot and cut wire shot: can even throw grinding, it does not hurt the workpiece, not easily broken, wear-resisting degree is high cycle grinding of long service life.
Grinding balls perform standard:
A, appearance Grinding balls should be oval, long, flat sheet number of particles in finished products shall not exceed the amount of tested 10 ﹪;
Second, the specifications of the specifications of the grinding balls range 0.6 0.8 # #, # #, # 1.0, 1.0, 1.0, 1.7, # # #, # 1.8, 1.8, 1.8.
Three, technical requirements of the chemical composition of grinding balls and content, shall comply with the terms of the following:
Chemical composition of C, Si, Mn P S
Contain quantity ﹪ 0.65 1.10 0.8 1.65 1.20 2.0 < 0.05
Four, hardness of the grinding balls HRC: 50-65 (no tempering HRC: 40-50 (temper)
Five, the microstructure of grinding balls are made of tempered martensite, tempered troostite
Six with crack, crack grinding balls shall not exceed the amount of tested 3 ﹪
Physical properties of grinding balls, capricious for I, the tensile strength of 1520 n/m ㎡
Eight, cycle life The cycle life of grinding pill is cast steel shot, steel cut wire shot more than 2.5 times.
Grinding balls features:
1. The composition of grinding balls is stable.
2. The grinding balls toughness and high tensile strength.
3. The grinding balls to overcome all the weakness of cast steel shot, pore-free, not broken.
4. Long service life.
The consumption of grinding balls and cast steel shot than:
Iron (deoxidization)
Large > 1000 kg of medium material 1000 kg small < 10 kg
Cast steel shot consumption 2-4 kg/ton 6-8 kg/ton 8-10 kg/ton
Consumption of grinding balls 1-2 kg/t 3-5 kg/t 4 -- 6 kg/ton
specifications
Grinding balls of the specifications of the range of 0.6 # # #, # 0.8, 0.8, 1.2, 1.4, # # #, # 1.7, 1.7, 2.0,
The superiority of grinding balls than cast steel balls reflected in the following aspects:
1. The composition of grinding balls is stable.
2. The grinding balls toughness and high tensile strength.
3. The grinding balls to overcome all the weakness of cast steel shot, pore-free, not broken.
4. Long service life.
The consumption of grinding balls and cast steel shot than:
Iron (deoxidization)
large
> 1000 kg medium
Material 100 kg small
The < 10 kg
Cast steel shot consumption 2-4 kg/ton 6-8 kg/ton 8-10 kg/ton
Consumption of grinding steel balls 1-2 kg/t 3-5 kg/t 4 to 6 kg/ton
