HEAT TREATMENT AND SAFETY PRECAUTIONS OF FORGING

HEAT TREATMENT OF FORGING

Heat treatment is carried out for releasing the internal stresses arising in the metal during forging and cooling of work piece. It is used for equalizing the granular structure of the forged metal and improving the various mechanical properties. Generally forged parts are annealed, normalized and tempered to obtain the desired results.

SAFETY PRECAUTIONS

Some safety precautions generally followed while working in forging shop are given as under.

1. Always avoid the use of damaged hammers.

2. Never strike a hardened surface with a hardened tool.

3. No person should be allowed to stand in line with the flying objects.

4. Always use the proper tongs according to the type of work.

9. Always keep the working space clean.

10. Proper safety guards should be provided on all revolving parts.

11. Head of the chisel should be free from burrs and should never be allowed to spread.

12. During machine forging, always observe the safety rules prescribed for each machine.

13. One must have the thorough knowledge of the working of the forging machine before operating it. Copied from Introduction to Basic Manufacturing Processes and Workshop Technology by Rajender Singh.
