Forging steel ball production process

1, the traditional process: as the name suggests is forged steel ball, the use of air hammer forging the raw material to a certain amount of deformation, increase the compression ratio, so that the organizational structure of the ball more compact and improve the toughness and hardness. The traditional process needs to be cut according to the size first, and then heated to a certain temperature with coal or natural gas, air hammer forging, heat treatment, product inspection of traditional processes have too many drawbacks, the most important are inefficient production, product quality is man-made Control leads to individual differences, serious environmental pollution, labor intensity, heat radiation and noise radiation and other serious endanger the health of workers. Raw materials: raw materials for forging steel ball - round bar, all ordered from the national large-scale steel mills, and can be special wear-resistant steel ball ball material special requirements for special processing.

Raw material heating: We use energy-saving induction heating rod furnace, can ensure uniform temperature of the entire raw material and greatly reduce the loss of raw materials, heating the uniform temperature of the raw material can ensure wear-resistant steel ball ball in the heat treatment process uniform hardness. Heat treatment system: through self-developed water quenching heat treatment production line and the scientific heat treatment process, can be free to control the wear-resistant steel ball into the water temperature and water temperature so that forging ball from the surface to the core hardness and higher toughness at the same time, Crushing rate is very low, in a variety of harsh working conditions to maintain the stability of wear-resistant ball.

2, oblique bar technology: With the development of the times, the traditional process gradually fade out of the historical stage, replaced by the oblique bar technology, oblique bar technology basic idea is to use the electric furnace to heat the entire root bar, through the delivery device into the roll through Motor and reducer drive roller rotation, the roller can use its own ball groove design will be high-temperature bar oblique bar into a ball. Oblique bar technology without cutting, without air hammer forging, greatly improving the production efficiency, labor intensity is greatly reduced, the noise and other hazards are also greatly reduced, oblique bar technology is forging steel ball industry leaps and bounds but oblique bar Technology has great flaws, the most important is the surface quality and roundness and other aspects of oblique bar technology sticking out of the steel ball surface of the skin, lack of meat, over burning, protruding, high degree of defects and other defects, and oblique bar technology When the diameter of the steel ball is more than 50mm, the indexes of the steel ball that are stuck out do not meet the requirements of relevant standards. Diameter greater than 90mm steel ball, Catenary technology has been unable to produce.

3, rotary cutting and rolling technology: With the development of the world mining machinery, ball mill diameter is getting larger, along with the emergence of semi-autogenous mill, miner steel ball for the ball mill needs from small diameter gradually updated to large diameter. Obviously, the traditional technology and sloping bar technology can no longer meet the needs of the mine. Under such circumstances, Mr. Hou Yu Min, Chairman of Shandong Huamin Steel Ball Co., Ltd., led the technical staff of Huamin Company to independently research and develop through continuous exploration and experiment. After several years of hard work, he finally developed Successfully forged steel ball rotary cutting roll automation production line. Rotary cutting roller forging machine and other key technologies won five national patents, with its new RCAB series of proprietary materials, the products produced by the international mining giant "BHP Billiton" "Rio Tinto" "Vale" and other approved forging steel ball heat treatment system through Self-developed water quenching heat treatment production line and the scientific heat treatment process, the forging wear-resistant ball from the surface to the core of the higher hardness and high toughness at the same time, the crushing rate is extremely low, in a variety of harsh working conditions to maintain wear-resistant ball Stability.

Rotary cutting and rolling automation steel ball production line technology using a new automatic feeding technology, IF & HF induction heating technology, rotary cutting roll forging machine technology, spiral isothermal machine technology, drum spiral quenching machine technology, automatic insulation barrel, etc. Advanced equipment, production efficiency than the traditional process increased by nearly 20 times, the labor intensity and working environment has been greatly improved. With advanced induction furnace heating, replacing the coal and natural gas, energy saving, while not bringing pollution to the environment. Produced by the steel ball regardless of the surface quality or intrinsic quality, are more than the relevant indicators of the standard, roundness, hardness, impact value, drop values have exceeded the national standard. In particular, break the diameter of 100mm above the large diameter steel ball, can only rely on conventional air hammer forging routine. Can be described as forging steel ball Another leap in the history of development. At present, Hua Min company can produce forged steel ball diameter between 20mm-150mm.

4, forging steel ball liquid extrusion molding technology. Huaneng steel ball company is developing this technology and apply for patents, can not provide detailed information. I believe people will bring Huabing grinding ball production technology once again breakthrough innovation. Welcome domestic and foreign customers to visit our company negotiations, we are committed to provide you with high quality products, timely shipping, competitive prices and satisfactory service as our basis for long-term cooperation.
