Foundry Technology VTU Notes

I am student of Visvesvaraya Technological University (VTU) and from here doing engineering degree. Can you provide Foundry Technology notes of this university also provide me the Foundry Technology syllabus so that I get to know about subjects so I can prepare well for exam?

Visvesvaraya Technological University is a collegiate public state
university in Karnataka State, India.

It was established by the Government of Karnataka.

VTU Foundry Technology notes was not available below i am proviidng
you the syllabus of VTU Foundry Technology subject

VTU Foundry Technology Syllabus:

06ME838-Foundry Technology

PART – A

UNIT I:

FOUNDRY METALLURGY: Oxidation of liquid metals, gas dissolution in
liquid metals, methods of degassing, fluidity, factors affecting
fluidity, fluidity tests, hot tearing, shrinkage of liquid metals.

UNIT II:

CASTING DESIGN: Introduction to casting design, redesign
considerations, design for minimum casting stresses, design for
directional solidification, design for metal flow, safety factors,
design for low pattern cost and model making as an aid in design.

UNIT III:

SOLIDIFICATION OF CASTINGS: Crystallization and development of cast
structure - nucleation, growth and dendritic growth. Structure of
castings - significance and practical control of cast structure, grain
shape and orientation, grain size, refinement and modification of cast
structure. Concept of progressive and directional solidification,
solidification time and derivation of Chvorinov’s equation, influence
on mold characteristics and cast metal.

UNIT IV:

RISERING AND GATING: Need for risering, general considerations of
risering, riser shapes, riser size, and location. Requirements of a
riser. Sand, insulating, and exothermic materials used for risers.
Riser feeding distance and theory of risering. Internal chills,
external chills, use of mould materials of different chill capacities,
padding for directional solidification. Open type and blind risers.
Riser treatment using exothermic and insulating compounds. Gating
system – theoretical consideration of gating, laws of fluid flow,
turbulence in gating system, use of ceramic foam filters in gating,
need for tapered sprue, gating ratio, simple problems.

PART – B

UNIT V:

SPECIAL MOULDING TECHNIQUES: Principles, materials used, process
details and application of no-bake sand systems, vacuum moulding,
flaskless moulding, and high pressure moulding.

CUPOLA MELTING: Developments in cupola melting – hot blast cupola,
water cooled cupola, balanced blast cupola, cokeless cupola, cupola
charge calculations.

UNIT VI:

FERROUS FOUNDRY: Melting procedures, casting characteristics,
production, specification, and properties of some typical steels, grey
cast iron, malleable iron, and spheroidal graphite cast iron castings.

UNIT VII:

NON-FERROUS FOUNDRY: Melting procedures, casting characteristics,
production, specification, and properties of some typical aluminum,
copper, and magnesium based alloy castings.

UNIT VIII:

MODERNIZATION AND MECHANIZATION OF FOUNDRY: Need for modernization,
and mechanization, moulding and core making, melting, pouring, shake
out equipment and fettling, dust and fume control, material handling
equipments for sand moulds and cores, molten metal and castings,
reclamation of sands. Pollution control – norms, and agencies.
