forging rolled grinding media balls, grinding media forged mill steel balls
Suizhou Gaincin Machinery Co.,Ltd(Gaincin.com) is a manufacturer and exporter of hammering forged ball & hot-rolled steel ball by national standards.The annual output of grinding balls is 80,000 Tons. Hot-rolled steel ball process is a new technology developed by our company, it has a good quality. Our company choose the high quality special steel as a raw material, it fundamentally improves the quality of steel balls.Hammered forged ball,hot rolled steel ball is a new rolling technology, it is the technical breakthrough of ball milling manufacturing process, and it is replacing casted steel ball gradually.
After our technical sufficient study and transform for steel ball rolling line, a new generation of steel ball production line is developed. Through multiple innovative designs, it has following features:
1. Overall design for roller box, with good rigidity;
2. Simple adjustment, easy operation;
3. Locking fastened, with high stability;
4. Replacing guides is simple and quick, with high efficiency. Provide guarantee to steel ball rolling line stable, efficient and high quality operation.
Major Production Process:
1. After steel rod inspection, shearing to semi-finished steel rod by specified length
2. Before rolling the semi-finished steel rod, it need to heated to proper temperature in the continuous heating furnace.
3. After red state of steel rod is fed into the ball rolling device, it will rotate between the two rollers with special spiral groove, and then continuously rolling as steel ball. Each ball rolling mill can roll 60-120 steel balls per minute.
4. red state steel ball after rolling will immediately put into on-line heat treating machine for quenching-tempering treatment, make steel ball has high and even hardness.
The characters of the technology:
①Choose the high quality special steel as a raw material.②Heat up the round bar to 1080℃.③Round bars are rolled to steel ball by skew rolling mill④The steel balls has high toughness and extremely low broken rate by quenching and tempering. It is stable in long-term use and the use effect are satisfactory in different mines，all kinds of grinding machines, all kinds of bad environments.
Parameters of hot rolled steel ball:
1. The overall high hardness: surface hardness of 57-67 HRC, volume hardness of 56-64 HRC, and the hardness gradient distribute evenly.
2. High impact toughness: more than 12 J/CM2
3. Low broken rate: anti-broken and anti-broken off performance is 10 times of general casting steel ball, balls impact times over 20,000 times, the actual broken rate is less then 1%, close to no broken.
