NCTS/NITTTR/2 : Blow Holes
Mrs. Sharadini S. Karkhanis
Blow Hole is a common defect. At times this defect is confused with other defects which appear similar to Blow Holes. This leads to faulty diagnosis.
The programme illustrates this defect and Instructs to distinguish Blow Holes from other defects such as sand holes, slagholes, and shrink holes, other contents are :
- Locating blow holes
- Characteristic features of Blow Holes
- Genesis of the defect
- Remedial measures
NCTS/NITTTR/3 : Shrinkage
Mr. Suhas K. Paknikar
The programme deals with the following :
- Characteristic features of appearance of the defect
- Classification into open, internal, corner, centerline etc. illustrated with animations
- Genesis - mechanism of formation of shrinkage cavities
- Causes leading to shrinkages and
- Remedial measures
NCTS/NITTTR/4 : Inclusions
Mr. P. S. Godbole
Inclusions in foundries form a significant part of Total rejections and are required to be attended seriously.
The programme encompasses :
- Identification of Inclusions
- Classification into sand and dirt, slag and slag like matter
- Causes e.g. Design, Patterns, Pattern requirement, moulding boxes, gating and running, moulding sand; core practice, moulding practice, Metal composition, Melting Practice, Pouring Practice, etc. - animations
- Remedies
NCTS/NITTTR/5 : Scab
Mr. A. K. Abhyankar
The programme deals with the following :
- Appearance of defect
- Classification into expansion scab and erosion scab
- Causes leading to scabs illustrated with animations
- Remedial Measures
The concept of scab is concretized through animations for ease of understanding.
NCTS/NITTTR/6 : Discontinuities
Mr. S. A. Joshi
Discontinuity appears due to lack of fusion of metal in castings.
- The defect Cold lap, cold shut, Misrun, inadequate fusion of chapters etc.
- Causes of the defect and
- Remedial measures
In foundry practice we can not take remedial steps in isolation. This point is dealt with through live action, graphics and voice over narration.
