Hot-rolled steel ball(Grinding steel ball) which are rolled by skew rolling mill produciton line overview:
Hot-rolled steel ball(Grinding steel ball) which are rolled by skew rolling mill produciton line is a new rolling technology, which is a breakthrough technology in manufacturing of ball milling, this kind of ball is being gradually replace the casting ball.
hot rolling steel ball(Grinding steel ball) which are rolled by skew rolling mill produciton line has the following characteristics:
1, Hot-rolled steel ball has all the advantages of steel, becoming high quality grinding mill ball after heat treatment.
2, High efficiency, high yield, high mechanization and automation of production, there is no manual operation on the production chain, less employment, smallman-made interference.
3, Stable quality, high hardness, good hardenability, fine microstructure dense, fine grain size, no deformation, the ball does not deform from the verybeginning to end, never lose round shape, good wear resistance, toughness can up 12-35J/cm2, broken rate less than 1%.
4, Low energy consumption, no pollution, low labor intensity, low production costs.
5, Good shape, less geometric tolerances, stable quality.
6, Low wear rate, long life, 2-5 times more than existing cast iron ball, forged steel ball, and the prices are same.
7, Ball hardness up to 60 ~ 67HRC, internal and external balance of hardness is even, hardness difference <5HRC.
8, Impact toughness up to 12 ~ 35J/cm3.
9, Large density (7.8 ~ 7.85g/cm3).
Hot rolled steel ball (Grinding steel ball) which are rolled by skew rolling mill produciton line technology:
Ball diameter range Φ25-Φ125mm. Rolling ball milling is used in a variety of chemical composition billets rolled round bars, its diameter is equal to the nominal diameter of the ball. The main production process of hot rolling steel ball as follows:
1, After the round bar examination, by length cut into steel ball billet.
2, The steel billet heated to a suitable temperature in a continuous heating furnace before rolling.
3, After the red-hot state steel billet feeding into the ball mill, forward rotation in between special spiral grooved rollers, and is continuously rolled into a ball. Each steel skew ball mill can roll 60-360 steel ball per minute.
4, The red hot ball rolled into special designed online heating treatment furnace for quenching – tempering heat treatment, so can get high uniform hardness ball.
5, After inspection steel balls sent to the finished goods warehouse, after packaging then sent to customers.
Hot-rolled steel ball(Grinding steel ball) which are rolled by skew rolling mill produciton line advantage:
Our Hot rolled steel ball with precise dimensions, round geometry, high hardness and good mechanical properties and with high wear resistance, no distortion, no cracking of excellent quality.
The characteristics of hot-rolled steel ball(Grinding steel ball) which are rolled by skew rolling mill produciton line as following:
1, High overall hardness: the surface hardness can reach 55-65HRC, volume hardness can reach 50-62HRC, and the hardness gradient distribution even.
2, High impact toughness: toughness greater than 12J/cm2.
3, Low broken rate: anti-peel broken and anti-crushing performance is more than 10 times the normal casting and forging steel balls, falling ball impact more than times 20,000, while the actual breakage rate less than 1%, close to no broken. Hot rolling steel ball adopted in all kinds of ball ferrous and nonferrous metals processing plant mines, power plants, cement plants, refractory plants and other industries.
