PART-1  TECHNICAL BID

TECHNICAL SPECIFICATION AND PRE REQUISITE REQUIREMENT OF HI CHROME GRINDING MEDIA FOR BBD MILLS AT OPGC IB TPS
A. CHEMICAL COMPOSITION: The specification of Hi Chrome grinding media should have the following chemical composition:

Hardness : Minimum 57 Rc
Retained Austenite : Maximum 15%
Microstructure : Wholly tempered martenistic with trigonal (Fe-Cr)7 C3 type finally dispersed, complex carbides. All other details e.g finish, freedom from defects, scales,burns,heat treatment and other defects shall be as per relevant IS..
B. PRODUCTION FACILITIES PRE REQUISITE
a) Solid state controlled medium frequency induction melting furnaces for rapid and homogeneous alloy melting.
b) High pressure rapid mechanized moulding line.
c) Integrated on line automatic sand plant complete with knock off machine, cooling system, cyclone separator and magnetic particle separator.
d) Precise control of pouring temperature by immersion pyrometer.
e) Core sand mixer and electric core oven.
f) Rotating Breaker Drum for effective segregation of physically defective grinding media, runners & risers etc.
g) Facilities for manufacturing both liners and grinding media in order to ensure good compatibility and thereby derive optimum performance.
C. HEAT TREATMENT FACILITY
a) Computer controlled programmable multizone continuous pusher type furnace with multipoint Auto temperature controllers/recorders.
b) Electrically heated bogie hearth furnace.
c) Air and Oil quenching terminals.
d) Tempering furnaces with air circulation for imparting precise heat treatment cycle appropriate to specific alloy grade.
D. QUALITY CONTROL FACILITIES
a) On line chemical analysis facilities involving computerised vacuum emission spectrometer with reading element accuracy up to 0.001 % with ferrous background and with microprocessor base.

Retained austenite is to be strictly maintained below permissible limit as hard working conditions in tube mills can result in retained austenite getting converted to martensite resulting in volume expansion leading to :
- excessive wear of balls
- breakage of balls
