Process Features of Forged balls
Material stability:
Round steel, the raw material of forged balls, are totally ordered from our national large-scale steel mills.
We can also provide special processing as per special requirements of different grinding balls materials.
Heating of raw material:
We use energy-efficient induction bar heating furnace.
Advantages:
Ensure uniform temperature of the entire raw material, and then the uniform temperature can ensure even hardness during heat treatment process.
Lower raw material consumption.
Forging Forming:
The raw material is forged to a certain deformation by air hammer, increase the compression ratio, So that to dense the structure of wear-resistant ball and improve the toughness and hardness.
Heat treatment:
We use independently-developed water quenching heat treatment production line and scientific heat treatment process.
Our forging grinding balls have the specialities of higher hardness (from surface to the core), high toughness and low breakage. They can even maintain the stability under various poor working conditions.
Grinding steel ball application:
1) CEMENTPLANTS,
2) Metal mining in mines
3) power stations
4) Chemical engineering
The full series of available ball sizes includes 25mm (1 inch), 30mm (1 1/4 inch), 40mm (1 1/2 inch), 50mm (2 inch), 65mm (2 1/2 inch), 80mm (3 1/16 inch), 94mm (3 3/4 inch), 105mm (4 inch), 125mm (5 inch), 133mm (5 1/4 inch), 140mm (5 1/2 inch) and 150mm (6 inch).

Our company regulate and produce strictly according to the ISO9001 Quality Standard. The main products are:
1. Anti resistant steel ball: Dia. 20mm-dia. 150mm forged steel ball and high, medium, low chrome cast ball in dia. 17mm-dia. 120mm. Huafu steel ball is good in accurate dimension, roundness geometry shape high hardness and good mechanical properties with good characteristic of anti resistant, no deformation, no break. Huafu steel ball is uniform surface hardness, hardness distribution uniform for the advance quenching device in the producing process.
Huafu steel ball have the below characteristic: A: High hardness( surface hardness is50-65 HRC, volume hardness is 48-58 HRC with uniform hardness distribution); B: High impact toughness( above 12J/cm2); C: Low break rate( anti break is ten times compared to the normal cast and forged steel balls, factual break rate is lower than 1% when falling times is above 20, 000 from the 10 m high dropping machine) D: No deformation: Steel ball no deformation out of the round for using. Huafu steel ball is made from the perfect carbon steel and alloy steel.
2. Steel cylpeb: We absorb the advance technology, add the Cr, Mn, Si, Mg, Al, Cu and others to make the alloy cements. The products produce in the intermediate frequency furnace and fall to the high, medium, low chrome category. Its characteristic is steady quality, high hardness, anti resistant, low break rate, various kinds
3. Decorative wrought iron products: We mainly produce the forged baluster, spears, the assembles and the arctic iron door, fence, guarding windows, room furniture, various kinds for above. Our products are famous in the world by it's highly view and use value.
