steel ball skew rolling mill- steel ball rolling production line

Skew rolling mill production line used to produce steel balls or steel forging. The angle between the two rolls of the skew rolling mill is generally 2 -6 . The roll has a spiral hole pattern. When the two rolls are rotated in the same direction, the round billet rotates reversely with the roll between the rolls and advances through the spiral hole Round bar rolled into the desired shape. Then after the heat treatment process to meet the requirements of grinding steel ball.

The work principle of helical hole type cross rolling is shown in the figure. Two axes with helical hole cross each other. The rollers rotate in the same direction to rotate and advance the circular piece, under the action of forming rotary parts blanks. Skew rolling deformation is mainly axial compression of the axial extension.

The part has the storage 6000MM long bar steel rack, automatic feeding, automatic feeding, automatic temperature measurement, fault alarm and other functions, the high degree of automation of the furnace, to ensure continuous production of steel ball production line.

the advantages of hot rolled steel ball made by skew rolling machine - skew rolling mill

the advantages of hot rolled steel ball made by skew rolling machine - skew rolling mill

Hot rolled steel ball is a new kind of rolling technology, is the process of ball mill ball manufacturing technology breakthrough, is gradually replace the casting ball, hot-rolled steel ball has the following features: A hot-rolled steel ball has all advantages of steel, after heat treatment as a high-quality ball mill ball2, high efficiency, large output, rolling the ball production mechanization, high degree of automation, no manual production, employing less and less interference from human factors. Three, stable quality, high hardness, good hardenability and dense microstructure, small grain size, deformation, steel ball all not deformation, do not break round, wear-resisting performance is good, the impact toughness up to 12-35 j/cm2, broken rate is less than 1%; Four, low energy consumption, no pollution, low labor intensity, low production costFifth, forming good, geometric tolerance is small, stable quality. Six, low wear rate, long service life, is the existing cast iron ball, Classification forging steel ball 2 ~ 5 times, and the price. Seven, ball hardness can reach 60 ~ 67 HRC, inside and outside equilibrium hardness, hardness difference < 5 HRC. Eight, the impact toughness up to 12 ~ 35 j/cm3. Nine, than big (7.8 ~ 7.85 J/cm3). Rolling steel ball is a new kind of rolling technology, there are a lot of advantages, so what are the process of hot rolled steel ball? 1. The round steel bar after inspection, according to the specified length shearing ChengGangQiu billet. 2. The steel ball billet in a continuous furnace heated before rolling to the right temperature. 3. Red state of billet is fed into the ball mill, in between the two with special spiral groove roll rotation, and are continuously rolling ChengGangQiu. Each ball mill 60-360 per minute can be rolled into a ball. 4. Rolling into a red state of steel ball immediately after entering the factory specially designed online quenching tempering heat treatment, heat treatment equipment make steel has high and even hardness. 5. After the inspection qualified products sent to the finished goods warehouse, for packaging the coma to the customer.

Steel ball production methods generally have forged, rolling, semi-solid forming, and casting four categories. Due to historical and mineral processing industry is a holdover some special conditions of use and integrated environment, the background, in the industry, forging and rolling occupies a large proportion of the ball. The semi-solid forming with unconventional casting, it is not the simple die casting can explain the characteristics of the Qing dynasty, as a kind of be like casting, forging, casting advantages formed by both the advanced technology of excellent performance and cause the attention of people. While casting steel ball with its simple, flexible, and reliable mode of production, easy to realize the expansion of large-scale production in low investment advantage, especially when experts and engineers face furnaces use all kinds of advanced technology and alloy composition design, play to the endless imagination, Large diameter steel ball another one to create a newer, more advanced varieties, to meet the needs of the competition brought about by the sense of accomplishment, more very person can experience. The course of cost-effective and sustainable development of the ball potential, making it the current crushing industry especially cement grinding ball is in the way of production.

quenching and partitioningbased heat treatment for rolled grinding steel balls | springerlink

quenching and partitioningbased heat treatment for rolled grinding steel balls | springerlink

A Quenching and Partitioning (Q&P)based heat treatment has been applied to rolled grinding steel (0.75 wt pct C-Mn-Cr) balls of 104-mm diameter to prevent their cracking during heat treatment. The conventional route of ball manufacturing includes rolling, water quenching interrupted when the bulk average temperature is 220 C to 250 C, and self-tempering in a large pile. This technology leads to cracking when the balls are made of steel of high hardenability. To overcome this deficiency, the Q&P principle is herein adopted by (a) adjusting the quenching duration to cool the ball center below the martensite start (Ms) temperature and (b) instead of self-tempering applying furnace tempering. The target bulk temperature of the ball that ensures an optimal martensite/retained austenite ratio inside the ball at the moment of water quenching interruption is determined as 125 C to 170 C. Quenching should be followed by tempering at 200 C to 250 C for stress release at the surface and carbon partitioning from martensite to austenite in the core. The resulting microstructure varies from tempered martensite in the shell layers to a mixture of martensite-bainite and retained austenite (RA) in the inner zones, where the austenite content is 25 to 30 vol pct. The carbon enrichment in austenite toward the core of the ball leads to balanced stresses and prevention of ball cracking. Q&P-heat-treated balls in an industrial-scale trial attained a uniform hardness of approximately 55 HRC through the cross section and a high fracture resistance under repetitive impacts of 6.8 kJ energy each.
