High chromium wear-resistant ball design, which ball mill barrel steel ball is safe

Since the end of last century, steel ball processing and manufacturing industry has been improved gradually, which makes the steel ball industry develop rapidly. Due to the continuous expansion of the scale and number of steel ball industry, it also began to enter the era of meager profit. Due to the improvement of technology, various costs also rise, but as a micro part of mechanical equipment, the value range of steel ball is limited. With it comes a reduction in production costs. However, in order to reduce costs, many steel ball manufacturing industries "reduce labor and materials" or "replace inferior products with good ones". The purpose is to maintain a favorable price advantage and preserve the long-term development of the enterprise. But "reducing labor and material" is definitely not a feasible long-term solution. Now the market demand for steel balls, quality and price need to have competitive advantages. Because, scientific energy-saving measures are the competitive means of steel ball manufacturing industry.

4. Analysis of steel ball material (1) high manganese steel: the ball mill steel ball under this material has good toughness, good processability and low price. Its main feature is that under the action of large impact or contact stress, the surface layer will rapidly produce work hardening, and its work hardening index is 5-7 times higher than that of other materials, and the wear resistance is greatly improved. (2) Low carbon alloy steel ball: the ball mill steel ball made of low carbon alloy has good toughness and low price. Under the same working conditions, its service life is more than twice as long as that of low chromium cast ball.

There are three kinds of steel balls: forged steel balls, forged steel balls and hot-rolled steel balls. Forged steel ball: round steel section forged with air hammer. The wear resistance of the steel is closely related to the quality of the steel. The main raw materials of forged steel ball are 45 ᦇ steel, 50Mn, 60Mn or 65Mn. The advantages of forged steel ball are that the crushing rate is less than 1 ᦇ and it has wear resistance, low price and high cost performance. In the forged steel ball, chromium alloy is the main component of forged steel ball. The steel ball has poor oxidation resistance and high sulfur resistance, diesel resistance and corrosion resistance to nail polish. Its strength density is lower than that of forging steel balls, and its crushing rate is much higher than that of other steel balls.
