AS2074 L / 2B Steel Cr-Mo Alloy Steel Castings For Composite Rubber

Quick Details

Cr-Mo Alloy Steel Castings used in Composite Rubber Feature:

1.Cr-Mo Alloy Steel Castings have popular application in Australian mines;
2. Steel casting can be safely used in AG mills.

Cr-Mo Alloy Steel Castings used in Composite Rubber 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. Cr-Mo Alloy Steel Castings used in AG mill & SAG mill.
