(e) It is totally hygienic, termite and pest proof.
(f) Stainless Steel also known as the new age green metal is 100% corrosion resistant, recyclable
and long lasting.
1.6 STAINLESS STEELS (RAW MATERIAL)
(a) When 11.5% or more chromium is added to iron, a fine film of chromium oxide forms spontaneouslyon the surfaces exposed to air. This film act as a barrier to retard further oxidation, rust or corrosion.
As this steel cannot be stained easily, it is called stainless steel.
(b)All stainless steel can be grouped into three metallurgical classes:- AUSTENITIC FERRITIC MARTENSITIC
1.6.1 AUSTENITIC STAINLESS STEEL
They possess austenitic structure at room temperature. They possess the highest corrosion resistance of all the stainless steels. They possess greatest strength and scale resistance at high temperatures. They retain ductility at temperature approaching absolute zero.
7/22/2019 Final Industrial Training Report Me

They are non-magnetic so that they can be easily identified with a magnet. They have the following composition
C 0.03 to 0.25% Mn 2 to 10%
Si 1 to 2% Cr 16 to 26% Ni 3.5 to 22% P Normal S Normal Mo In some cases Ti In some cases
They are used in: Aircraft industry (engine parts) Chemical processing (heat exchangers) Food processing (kettles, tanks) Household items (cooking utensils) Dairy industry (milk cans) Transportation industry (Trailers and railways car), etc.
1.6.2 FERRITIC STAINLESS STEELS
They possess a microstructure which is primarily ferritic. Ferritic stainless steels have a low carbon-to-chromium ratio. This eliminates the effects
for thermal transformation and prevents hardening by heat treatment.
These steels are magnetic and have good ductility. Such steels do not wr4ok harden to any appreciable degree. Ferritic steels are more corrosion resistant than martensitic steel. Ferritic steels develop their maximum softness, ductility and corrosion resistance in the
annealed condition.
Ferritic stainless steels have the following chemical composition:

C 0.08 to 0.20% Si 1% Mn 1 to 1.5% Cr 11 to 27%
Ferritic stainless steels have the following uses: Lining for petroleum industry Heating elements for furnaces Interior decorative work Screw and fittings Oil burner parts
1.6.3 MARTENSITIC STAINLESS STEELS
Martensitic stainless steels are identified by their martensitic microstructure in thehardened condition.
Because of the higher carbon-to-chromium ratio, martensitic stainless steels are the onlytypes hardenable by heat treatment.
These steels are magnetic in all conditions and possess the best thermal conductivity ofthe stainless types
Hardness, ductility and ability to hold an edge are characteristics of martensitic steels. Martensitic stainless steels can be cold worked without difficulty, especially with low
carbon content, can be machined satisfactorily, have good toughness, show good
corrosion resistance to weather and to some chemicals and are easily hot worked.
Martensitic stainless steels have the following composition:
C 0.15 to 1.2% Si 1% Mn 1% Cr 11.5 to 18%
A few typical use of martensitic stainless steels are as follows:

1.7 WELDING
(a) Welding is the process of joining similar metals by application of heat with or without
application of pressure and addition of filler material. The application of welding are so varied
and extensive that it would be no exaggeration to say that there is no metal industry and no
branch of engineering that does not make use of welding in one form or another.
TYPES OF WELDINGS:-
1.7.1 TIG WELDINGTIG welding is a commonly used high quality welding process. TIG welding has become a
popular choice of welding processes when high quality, precision welding is required and it is
mainly used for Stainless Steel because it gives good finish as compare to MIG welding.
1.7.1.2 TIG WELDING BENEFITS
Superior quality welds Welds can be made with or without filler metal Precise control of welding variables (heat) Free of spatter Low distortion

2.3 LASER CUTTING MACHINE
Possess good speed and precise cut when cutting thin material. Laser yields no burr, a little HAZ. Laser is
suitable to cut non-reflective mild steel.
2.3.1 Principle
An extremely concentrated force of water is used in such kind of machines to cut jobs of very high
thickness. In this machine water at very high pressure that is ranging from 30000-60000 psi(N/m^2)when
mixed with very fine abrasive garnets (Silicate or sand ) is used to cut very hard materials like stainless
steel, titanium, Glass, ceramic tile, marble and granite. Also due to the fact that water at room temperature
itself is used as a cutting tool therefore the Heat Affected Zone (HAZ) is very less. Hence a very high
grade finishing is obtained compared to other machining processes. Moreover, since it is a cold cutting
process hence it is safe to cut inflammable materials as well.

Elevator consists of a belt on which large no. of buckets are attached. With the help of thesebuckets, shots are carried at the top from their the shots goes to Hooper 1 & 2.
Shots are made of iron carbide.
2.8.1 SHOT BLASTING TECHNOLOGYThe principle of blast cleaning technology is based on the use of the high kinetic energy of shot and grit
resulting from its mass and impact velocity see Figure 1 (on the left). A bundled stream of grain-sized
hard particles is accurately flung at high speed against a surface or work pieces. Depending on the reason
for blast cleaning a wide variety of surface conditions on the work piece treated can be produced.
Depending on the application, different materials are used for shot blasting

2.8.2 ROUTINE ACTIVITIES
Ensure uniform blasting in full width on strip. Check the Wheel current 5to6 times in every shift. Turbine load to be around 40 to 60 amps. If it
is less the blasting will be insufficient. Note down the load in log book
Maintain minimum 75% of shots level in the storage bunker in the running operation. Switch off all the wheel in case of breakdown Clean the shots in the bottom of bucket elevator before switch on the elevator Switch OFF control supply when the machine is not in use. Check the leakage from any part of machine. If there is some noise in the machine, inform to maintenance dept.

VARIOUS TYPES OF THEORIES USED
3.1 TPM-(TOTAL PRODUCTIVE MAINTENANCE)
It is a maintenance process developed for improving productivity by making processes more reliable and
less wasteful.TPM aims to---
Continuously improve all the operating conditions, within a production system; by stimulating daily
awareness of all the employees.
TPM primarily focuses on manufacturing but was later expanded to cover suppliers and customers as
well. Basically it is a company-wide team-based effort to build quality into equipment and to improve
overall equipment effectiveness.
Goals of TPM
Zero Breakdown Zero Losses Zero Pollution Zero Health Hazards
3.1.1 Eight Major Pillars of TPM
Jishu Hozen(Autonomous maintenance)Uninterrupted operation of equipments.
Flexible operators to operate and maintain machines and equipments.

3.2 Concept of 5 S
SEIRI-------Sorting SEITON-----Systematic SEISO------Cleaning SEIKETU----Standardisation SHIT SUKE----Training & Discipline
3.2.1 The Origins of 5S
5S developed, as with so many of todays best practice tools, in Japan. We first heard of it
as one of the techniques that enabled what we then termed Just in Time Manufacturing. The
Massachusetts Institute of Technologys 5-year study into the future of the automobile in the
late 1980s[2]identified that the term was inappropriate since the Japanese success was built
upon far more than components arriving only at the time of requirement. John Krafcik, a
researcher on the project, ascribed Lean to the collective techniques being used in Japanese
automobile manufacturing; it reflected the focus on waste in all its forms that was central to
the Japanese approach. Minimised inventory was only one aspect of performance levels in
companies such as Toyota[3]
and in itself only arose from progress in fields such as quality
assurance and Andon boards to highlight problems for immediate action.
5S was developed by Hiroyuki Hirano within his overall approach to production
systems.Many Western managers coming removed stored elsewhere or eliminated
completely. By differentiating between Seiri and Seiton, Hirano made the distinction explicit.
He taught his audience that any effort to consider layout and flow before the removal of the
unnecessary items was likely to lead to a sub-optimal solution.

PROJECT WORK
5.1 MY RESPONSIBILITIES AND TARGETSAfter joining as GET (Graduate Engineer Trainee) in the company we have
gone through a very good induction period of one month in which we learnt
each and every function of the company , its working culture , our colleagues ,
and after the completion of the induction programme. They gave me my
responsibilities and duties in production department under the guidance of Mr.
Sandeep Malik (Associate manager) where I am working as a GET in brand
section (arttdinox and krome) .where I am expected to fulfill my targets and
my targets are as under:
To improve productivity To reduce rejections and rework in weld shop and polishing dept. To improve OEE i.e Overall Equipment Efficiency Ensure on time delivery from lathe shop and weld shop
According to companys terminology, they called these responsibilities
as KEY RESPONSIBLE AREAS (KRA) a type of score card in which
every employee has its monthly , quaterly and annual targets, and on
the basis of the individual performance one has to rate himself byGRADES (A,B,C,D) and then it has to be verified by the boss.
Based on the KRA grade we have got a PLI scheme i.e Performance
Linked Incentive .

5.2 IMPROVEMNENT PROJECT- To improve the quality aswell as life of the draw tool
The panel of experts in the company decided to give me an improvement
project as I joined the organization with a lot of expectations. They offer me
to be a part of team which is going to work on the improvement of the life and
quality of the draw tools. I accepted this opportunity and started working on it
with the team. The details of the project are as under:

Existing conditions:
The life of tool is 1800 Pcs. After that we need to grind tool again
for reuse that tool. Burr on circle causes draw lines and wrinkles
on bowls and also affect tool life.

5.2.4 Corrective action taken by usAfter doing a lot of study and we observe that due to some
irregularities and burrs on the outer periphery of the circle the pressure
plate and tool are gradually degrading. And for this we decided to add
an operation in the sequence of the operations. What we did is just
have the periphery of the circle polished before the initial operation
(draw) in the sequence. So that the burrs can be removed from the
periphery of the circle.
