1.Company Profile
Our company”Zhangqiu Ruinian Casting and Forging Co,LTD is a professional company in producting grinding media, including forged steel ball,grinding steel ball,casting iron balls in China. Grinding steel balls are mainly applied in mines,power station,cement plants and chemical fields.The steel balls made by us are of high hardness, even wearing,good wearing resistance, no breakage,which can really reduce the cost for customers.The sizes are available from DIA20-150MM, annual production capacity 20000tons. which are strictly manufactured as standard YB/T091-2005 grinding ball,which are exported to Japan,Korea,Australia and other countries and regions and obtained high reputation from them.
2.Status of the industry of China's grinding balls
Grinding balls are used for grinding ore blocks in an abrasive media , widely used in mining iron ore and non-ferrous metals processing plant , cement plants , power plants , refractory plants, steel mills , phosphate fertilizer and other flour mill industry . In this grinding ball milling ore block , while also continue to wear smaller, until failure , thus consume enormous.
At present , China's annual consumption of about 400 million tons balls , mainly cast iron ball , forged steel ball . Milling ball diameter size normally used for Φ20mm ~ Φ125mm, the maximum diameter of large ball mill use is Φ130mm ~ Φ150mm. Ball milling production process are: cast iron ball , forged steel ball, rolling ball .
3.Comparison of forged steel grinding balls and cast steel ball
Cast iron ball technology advantages: simple equipment, low investment . Production technology and operation easy to grasp ; multi- standard , low-volume orders, arrange production easy and flexible.
Process Disadvantages : more casting defects ( holes, blisters , inclusions, surface cracks, etc. ) ; low density and a small specific gravity ; metals coarse grain , poor impact toughness ( generally 3 ~ 7J/cm2); high-energy, metal recovery low ; great Φ40mm casting difficulty following the ball .
Forged steel ball technology advantages: less investment , start fast , raw materials can be used both hot-rolled bar , can also be hot-rolled steel billet , billet length limitation , the production is easy to organize .
Process Disadvantages: difficult to stabilize production quality control ; artificial cutting , single mixed ; easily lead to the ball surface fold ; heating defects, oxidation and decarbonization , grain coarsening , and even overheating, burning ; final forging temperature, and quenching inconsistent quality ; hardness of the product , hardenability and toughness can not guarantee stability ; low efficiency and high cost.
