Forging steel ball seemingly technical requirement is not high, only need a caused to go, and in fact, the inside of the technology can be deep differences.

First forging steel casting steel ball more than corrosion resistant, so from a global perspective, all wet grinding ore powder or other materials, typically use the forging steel ball, no matter what kind of forging steel ball, finally all just test a index: cost-effective. That is the unit in the finished product grinding media the abrasion of.

Generally speaking, the current domestic market can be divided into three kinds of forging ball,

1 bearing steel ball,

Steel ball bearings, first of all raw material prices high, the second production process needs oil ZhanHuo, or easily broken. Even if the last production out, because its material limitation, its quench-hardening ability is insufficient, also not exactly how resistant.

2 waste ball

Because some materials is relatively relatively tidy, so they use some applications, after many small factories to purchase, will the forging for steel ball, this kind of steel ball because its material cheap, so the price is relatively low, but because its material not neat, so period after the ball hit, tolerance range too large, used to make the material process from expected output range, make the finished product is unqualified; Due to the use of the materials are abandoned, so the quality control is also hard to attain perfect.

3 is round steel industry or a steel ball forging

This kind of steel ball is the real meaning of wear-resisting steel ball, the steel ball in the raw materials procurement usually begins the major steel procurement and come, so on quality is assured, quality of steel ball 80% depends on raw materials. Since then, after heat treatment and backfiring technology enables it to achieve the expected hardness and toughness, both must wear-resisting have not broken. We (shandong HuaMin steel ball Co., LTD) is a professional production wear-resisting steel ball of the enterprise, the development of the company in 25 years, from the initial a caused, to now full automatic production and quality control, the experience of 25 years of market efforts, from the first to the original price has now customers requirements and quality first a qualitative change. Now we have our own research and development team of more than 30 people, from patent production materials (15 kinds of patent production material research and development success), to patent production process (the automation of no one to participate in the production, ensure the production process and quality consistent) and patent quality control process (according to the customer request to do 20 HRC-68 HRC different quality of steel ball, ? Inside and outside hardness difference really achieve less than 2 HRC), has already become the forging steel ball line standard.

Our company is specializing in the production of international standard 58-65 HRC wear-resisting steel ball has already won the domestic and foreign large-scale mining recognition, international giant Rio tinto and BHP billiton and we have the resources and business. By our clients.

We can produce forging steel ball can produce DIA 20 mm-DIA 150 mm, HuaMin steel ball with precise dimensions, roundness of the geometric shape, high hardness and good mechanical properties and wear resistance has, deformation, craze of the excellent quality. We produce wear-resisting of steel ball basically has the following advantages:

1, whole high hardness: surface hardness to 55-67 HRC, volume hardness of 50-63 HRC, and the hardness gradient distribution average.

2, impact toughness high: impact toughness more than 12 J / ㎝ 2. (generally greater than 30)

3, broken rate is low: the fragmentation is generally casting of the grinding ball 10 times above, balls impact times over 20000 times, the actual broken rate is not higher than 1%.

4, deformation: steel ball after not deformation, lost the circle
