JNTUK B.Tech Foundry Technology gives you detail information of Foundry Technology R13 syllabus It will be help full to understand you complete curriculum of the year.
Course objective: The course deals with various types of Foundries, patterns, moulding materials and different types of casting methods including modern methods.
UNIT I : Learning Objectives: To know about various types of foundries and know the patterns and moulding sands and additives used for getting good molds. Scope and development of Foundry. Types of foundries.
PATTERNS: Materials for patterns, types of patterns; functions and pattern allowance. MOULDING MATERIALS: Moulding sands, properties and selection of materials and additives used.
UNIT II : Learning Objectives: To know indetail about various casting processes and properties in molds. Gating and risering in molds.
CASTING PROCESSES AND EQUIPMENT: Green and dry sand moulding; shell moulding, CO2 moulding. Core moulds and cores. Plaster mould casting, composite mould casting, Investment casting.
GATING AND RISERING: Gate nomenclature, gate types and types of risers.
UNIT III : Learning Objectives: Study of different molding processes and their equipment Permanent mould casting, pressure die-casting, Gravity die-casting and centrifugal casting, Types of moulding equipment.
UNIT IV : Learning Objectives: Solidification of metals and alloys and melting practices to be studied
SOLIDIFICATION OF METALS: Nucleation crystal growth. Freezing of metals and alloys. Dendritic freezing. Coring and segregation, ingot defects, Flow of metals in moulds.
MELTING OF FERROUS ALLOYS: ‘Melting of Gray iron and cupola. Cupola operation and control. Effect on chemical composition, carbon equivalent and effect of alloying elements on foundry characteristics. Melting of non-ferrous alloys: Melting of Aluminium and copper alloys production processes: Production of Gray Iron, ductile iron. Malleable iron castings
UNIT V : Learning Objectives: Various casting defects and their prevention to be studied
CASTING DEFECTS: Casting defects arising due to moulding, coring melting and poring practice.
UNITI VI : Learning Objectives: Study of modern molding processes to be studied
MODERN DEVELOPMENTS: Recently developed processes – v- forming full mould process – Furon-no-bake sand moulds and cores. Continuous casting. Cold setting and self-setting processes
(Assessment: The student should be evaluated based on the assignments and objective tests. The student’s analytical abilities (with special focus on academically weak students) should be tested periodically in classes by giving problems). Emphasis should be given by conducting tutorial classes at the end of each unit.
