The general advantages in Semi-autogenous Mill Liner are as follows:
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 productin the latest standard of the electric-power industry in China.
Double-Media Quenching Chromium-Molybdenum Alloy Steel Series:
We specially design the material for mill linings in mines, coal-fired power plants and cement plants,etc..
With our special double media 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 Mill linings of large and middle size ball mills at home and abroad.
The match of Middle Chrome Mill Linings and High Chrome Cast Balls has been the typical model in coal mills and cement mills.
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.
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 and twice of that of low Chrome alloy steel liners.
Meanwhile, we can produce high Chrome castings as per AS2027, ASTM A532 and BS4844.
Semi-autogenous Mill Liner:
In addition to our patented Boltless Mill Linings, we can produce liners as per the request of customers.
So far, we have been the regular suppliers of mill liners Now, we have supplied steel caps inserted in rubber lifters for SAG mills and AG mills to some mines in Australia and New Zealand.
Depending on the specific working conditions,all wear parts can be ordered as Manganese Steel,high Cr cast iron or Cr-Mo Alloy Steel.
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.
We have been exporting castings to oversea
1. 20-year Foundry Operation Experience.
2. Friendly & High Efficient Technical & Commercial Communication.
3. Professional Export Practices: Exported to +60 Overseas Countries.
