Mine Mill Liner Feature:

Mine Mill Liner?Description:

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.

h. Inlay Steel Caps inserted in rubber liners for SAG and AG mills.
