Specification :

Detail: 1.Pearlitic Cr-Mo steel castings have popular & safer application in mines;
2.The castings can be used stably in large mine.

Pearlitic Cr-Mo Alloy Steel Liners Using In AG Mill

a.The hardness for Pearlitic CrMo Cast Steel Cap: HRc33~ 42 ( HB310~ 390) ; Steel caps shall be sample hardness tested at approximately ten percent( 10% ) random selection;

b.Microstructure: Predominantly pearlite;

c.Chemical Composition: Every furnace heat shall be analysed by Spectrometer; A conforming sample shall be obtained from each furnace heat prior to pouring the mould( s) ;

d.Dimensional Checking & Gauging: 100% check; be compliance to drawing dimensions within specified tolerances;

1.By visual inspection, e.g. where a cross joint or other dimensional or shape defect is evident, dimensions shall be verified to drawing;

2.By gauges manufactured to check specific features or dimensions of individual casting;

e.Casting Soundness: Level 2 of AS2574 or equivalent standard, 10% of order selected at random to be free of shrinkage with UT; Assessment of casting soundness and internal integrity shall be by ultrasonic testing; Sectioning by cutting may be only be used as a macro view test, as the cutting process may remove the area of unsoundness;

f.Surface Finish: Visual inspection after shot blasting; To achieve an acceptable level of surface texture, freedom from defects and extraneous material or rust that have the potential to reduce wear-life or the effective bonding of a rubber product;

1.All wear surface to be free from surface defects that may affect fitness for purpose, and any from of grease or oil;

2.All wear surface to be free from any raised features or markings above the wear face;

3.All bonding surface to be free of defects that affect fitness for purpose and to be free of rust, scale and any form of grease or oil.

g.Reporting: Providing process, inspection & test result data by which

specification compliance can be traced.

1.To provide process, inspection and test result data by which specification compliance can be traced;

2. To provide a means by which steel cap performance, may be correlated to manufacturing data with respect to chemical composition, heat treatment, and hardness.
