  Manufacturing & Testing Process:
   

A.         Cast Steel Grinding Media Balls and Cylpebs :  

1.                   Pattern making        -           in machine shop/pattern shop

2.                   Sand Moulding         -           in moulding section by DISA- ARPA moulding machine and mould handling system.

3.                   Melting                    -           in melting shop by induction furnace.

4.                   Casting                   -           by ladle to mould in casting section.

5.                   Fettling                   -           in fettling shop by Shot Blasting Machine.

6.                   Heat Treatment        -           in oil fired/electric furnace and quenching in proper media.

7.                   Inspection               -           Checking size and shape visual examination for  surface  defect.   

8.                   Testing                    -         (a)  Chemical composition checking by dir ect  reading emission spectrometer.

     (b)  Hardness checking by Rockwell/brinell hardness testing

     (c)  Micro structure by computerized metallurgical microscope.

 
 
 

B.         Forged Steel Grinding Media Balls and Cylpebs  

1.                   Design of dies and preparation of dies for forging

2.                   Cutting Raw Steel in proper size and weight

3.                   Heating in oil fired furnace to required temperature.

4.                   Hot forging by die forging method or by drop forging.

5.              Heat treatment, Inspection and Testing

 		  
 
 
  
 
  Heat Treatment  
 
Heat treatment facilities should be capable of handling the entire production. No subletting of Heat treatment is permissible. The Heat Treatment furnace should be of continues tunnel type either oil fired or electrically controlled. The heat-treatment furnace should be equipped with multipoint automatic. Continuous temperature recording arrangement with minimum one thermocouple at 5 ft length of furnace covering different zones with automatic temperature control of micro processor  type. Separate temperature indicator for each thermocouple should be available.  System should exist for  calibration of the thermocouples, temperature   indicator and recorders   once in 6 months and the furnace to be calibrated once in a year. Water quenching facility with a capacity to accommodate water of mass 5 times the mass of the total charge which is to be quenched should be available with proper water circulation system to ensure that the temperature is within control. Arrangement should be available for agitation of the quenching medium and Noting the temperature .System should exist to ensure immediate quenching of casting  after Heat   Treatment to avoid drop in temperature. Arrangement of proper sealing of the Doors of Heat Treatment furnace should be available to avoid oxidation/scale formation on the surface of the castings. There should be positive pressure inside to avoid the entry of air from outside. The Heat Treatment recorder/Graph should have sealing arrangement to avoid  tampering. Alkali base mould wash should be used on moulds and cores. Positioning of the nozzles of oil fired furnace should be such that the flame does not come in direct contact with the castings. The burners should be calibrated once every three months
  
 
  Hardness  
 
is the property of a material that enables it to resist plastic deformation, usually by penetration. However, the term hardness may also refer to resistance to bending, scratching, abrasion or cutting. The ability of a metal to resist penetration. The principle methods of determining hardness of steel are the Rockwell, Brinell and Scleroscope Tests.
  
  Rockwell Hardness  
 
A hardness test performed on a Rockwell hardness testing machine. Hardness is determined by a dial reading which indicates the depth of penetration of a steel ball for softer steels and a diamond cone for heat treated and harder steels when a load is applied.
