INDUSTRIAL SPECIALTIES
Petroleum Specialties represent a group of products which find wide application in the various processing industries. These products are primarily used in processing for manufacture of high quality finished goods. In most cases the petroleum specialties become part of the finished articles.
They impart desirable properties to raw material to facilitate their processing into finished goods.
They assist in the processing operations of the manufactured articles.
They improve quality and serviceability of the materials being processed.
They generally form part of the manufactured articles imparting them desired properties.
They enhance the sales appeal of the finished articles.

NECESSITY OF CUTTING FLUID
Heat generation by external friction is reduced / minimised by placing a
suitable lubrication film between the rubbing surfaces of work piece, tool and
chip
Cooling / lubrication of contact surface between tool, work piece and chip
results in improved finish , higher cutting speeds, depth of cut, reduced
power consumption and reduced rate of tool wear.
Prevents the welding/seizure taking place between tool and work piece
resulting from high pressure and high temperatures.

TRIMOFINS IN PREFERENCE TO KOOLKUTS
When more lubrication is required between the contacting surfaces
When it is necessary to reduce friction between the tool and work
piece to maximum extent
In situations where it is necessary to prevent local welding of metal
particles to the tool face. Sulfurized additive type straight cutting oil
are best suited for this purpose
For machining of magnesium and its alloys, it is necessary to use
straight cutting oils as magnesium can combine with oxygen in water
and can create fire hazards

QUENCHING OILS
BASICS OF HEAT TREATMENT
When steel is heated and cooled, the iron it contains undergoes a
structural change. Hot steel at its critical temperature and above is a
solid solution of carbon in face - centered - cubic - iron - Austenite.
When Austenite is cooled rapidly it is transformed to Martensite -
hardest possible with body centred structure.
This cooling can be done by the process known as Quenching.

COOLING STAGES IN QUENCHINGA. Leindenfrost stage or vapour blanket stage - Formation of vapour due to sudden immersion of hot steel - Cooling of steel takes place by conduction and radiation - Vapours are poor conductors of heat - Cooling of metal is relatively slow
B. Vapour Transport Stage - Energetic boiling of quenchent - Wetting of metal
- Fastest rate of cooling
C. Liquid Cooling Stage - Formation of vapour bubbles is stopped
- Cooling by conduction and convection - Rate of cooling is slower compared to VT Stage.

•Change in the composition of steel•Insufficient heating of the metal to its critical temperature•Time lag in transferring the metal from furnace to bath•Thickening of oil due to oxidation / sludging / dirt•Inadequate agitation
FIRE HAZARDS•Contamination with lighter oil fractions.•Insufficient circulation.
•Hot Spots•Presence of water beyond 0.5%
•Foaming•Violent Boiling

METAL ROLLING OILS
Rolling of metals is a process by which the thickness of the metal is reduced to the desired level by means of rotating rolls.
![Page 53: INDUSTRIAL SPECIALTIES l Petroleum Specialties represent a group of products which find wide application in the various processing industries. These products](https://reader036.vdocuments.mx/reader036/viewer/2022062304/56649c785503460f9492e257/html5/thumbnails/53.jpg)
Metal rolling process may be divided into two basic categories :
Hot Rolling : Where the metal is pre-heated
and rolled
Cold Rolling : Where the metal is rolled at
the ambient temperature

PROCESSING OF GENERAL RUBBER GOODS
In order to process crude, synthetic or reclaimed rubber into condition suitable for use it must be put through several processes such as :
1. Break Down
2. Mixing
3. Calendering
4. Extruding
5. Preparation for curing
6. Vulcanizing
