B. The materials conform to:

GB/T 8263-1999,

BS 4844 3E,

AS 2027 CrMo 15/3,

AS 2027 CrMo 20/2/1,

AS 2027 Cr27,

ASTM A532 Class III type A 25% Cr,

ASTM A532Class II type B 15% Cr-Mo.

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.

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