    AS2074 Pearlitic Cr-Mo Alloy Steel Precision Casting Caps With HRC33-43

    1. Hardness difference from surface to center is less than HRC2.

    2. The series are designed for high abrasion performance.

    3. Hardness:HRc33-43,

    4. Impact value:AK≥60J.

    5.The bolt holes are clean, smooth.

    The Combined Self-fastened Boltless Ball Mill Liners

    This product, invented by Mr. Chen Changshun, senior engineer and the director of the company,

    is known as“China Best Liner”.It includes two parts, high wear resistance boltless plates, and highly

    expandable riveting plates, which are self-fastened and strengthened to withstand impact from mill balls.

    We possess famous patented product------

    Combined Self-fastened (Boltless) Ball Mill Liners, or called CHINA BEST LINER.

    In 2012, we registered a new patent about Liner Technology.

    In December of 2000, we successfully registered the international patent in Canada.

    In 1988 and 1997, we claimed domestic patents for ball mill liners .

    The outstanding advantage of our liners is boltless.

    The general advantages in ball mills are as follows:

    Output Increased


    Power Consumption Reduced


    Maintenance Decreased

    Above 98%

    The liners are easily installed and existing mills need no modification.

    The additional advantages in cement mills are as follows:

    No leakage of slurry

    No repairs during service periods

    Better reliability and stability

    Production Improvement

    Noise reduction

    In the recent 20 years, our liners have been widely used in large, medium and small ball mills in

    Chinese power generation, mining, cement, chemical engineering and metallurgical industries and

    super fine pulverizing equipments.It is the only recommended liner product in the latest standard of

    the electric-power industry in China.

    Materials 1: Double-Media Quenching Chromium-Molybdenum Alloy Steel Series

    We specially design the material for ball mill liners in mines, coalfired power plants and cement plants,

    etc.. With our special doublemedia quenching process, the material can not only achieve ideal hardness

    (HRC48~55) but also ideal toughness value (AK30~100J). It can completely meet the requirement of liners

    of large and middle-size ball mills at home and abroad. The match of Middle Chrome Liners and High

    Chrome Cast Balls has been the typical model in coal mills and cement mills. Meanwhile, the material is

    applicable to the teeth plates, armored plates and hammers of crushers and excavator bucket teeth.

    Materials 2: Pearlitic Chromium-Molybdenum Alloy Steel Series

    The Pearlitic Chromium-Molybdenum Alloy Steel Liners are widely used in AG Mill,SAG Mill and Ball Mills.

    Hardness: HB310-375 (equivalent to HRC33-42)

    Impact resistant Value: Ak≥60J (60×10×10mm) in normal ambient temperature.

    We can produce pearlitic Cr-Mo steel as per AS2074 Gr. L / 2B.

    Materials 3 : High Chrome White Iron Series

    High Chrome white iron we can produce include 15%Cr, 18%Cr, 20%Cr and 26%Cr. Under same working

    condition, the wear performance of High Chrome mill liners is four times of that of high manganese steel liners

    an twice of that of low Chrome alloy steel liners.Meanwhile, we can produce high Chrome castings as per

    AS2027, ASTM A532 and BS4844.Customer-made Mill Liners

    In addition to our patented Boltless Mill Liners, we can produce liners as per the request of customers.

    So far, we have been the regular suppliers of mill liners for Magotteaux and Foster Wheeler Power Group.

    Now, we have supplied steel caps inserted in rubber lifters for SAG mills and AG mills to some mines in

    Australia and New Zealand. Wear Parts for CrusherJaw plates and cheek plates for jaw crushers, blow

    bars and impact plates for impactcrushers, cone liners for gyratorycrushers, hammers for hammer

    crushers and concaves and mantles for cone crushers.

    Depending on the specific working conditions, all wear parts can be ordered as Manganese Steel, high

    Cr cast iron or Cr-Mo Alloy Steel.

    Technical Parameters

    Our foundry has complete melting, heat treatment and test equipments, such as mid-frequency induction

    electrical furnaces, quenching and tempering furnaces, blast shot, spectrometer, Rockwell and Brinell

    Hardness tester, impactor,UT tester and metallographic microscope. We achieved the certificate of quality

    management system ISO 9001:2000. We have been exporting castings to oversea markets, such as Brazil,

    Australia and South Africa.
