7. Foundary shop
1. Casting
• In this process, a liquid material is usually poured into a mould, which
contains a hollow cavity of the desired shape, and then allowed to solidify.
The solidified part is known is as a CASTING. Which is ejected or broken
out of the mold to complete the process.

8. 2. FURNACE
•Furnace is used for melting the metal .
•HMT has 3 furnaces, two of 3MT capacity and one of 1.5MT capacity
•All furnaces are induction type & temperature in the furnaces reaches up
to 1400-1450˚C

9. 3.MOULDING SAND

•Main constituents of moulding sand-
1. Silica sand :-
Silica 86-90%
Alumina 4-8%
Iron oxide 2-5%
And other smaller oxide Ti, Mn and Ca
2. Green Sand :-
Bentonite Clay 50-60%
pulverized coal 30-40%
Water As require

•In the heat treatment three point are important for this process:-
1. Time
2. Temprature
3. Material code ( which mattle use)
-:Operation:-
1. Carburising:-
material code - C2R,C2A,C2M
Box Carburising - 850°C (8 hour )
Liquid Carburising - 1751C (4- 5 hours )
2.Harding:-
material code - T1,T2,T5,T8,C45,C1 etc.
Tempreature - 840-860°C ( 12- 14 hours )

16. 3.ASSEMBLY
• K130 :- This is a cylindrical grinding machine. Here alphabet K
represent the scientist “Keuring” And Numerical value indicates the
maximum diameter of work-piece from ground.
