What is casting Methoding?
What is casting Methoding?
Methoding of casting is related to FOUNDRY TECHNOLOGY , it deals with design of gating system and riser for production of defect free casting.
What is the manufacturing process of cast iron?
It is made by reducing iron ore in a blast furnace. The liquid iron is cast, or poured and hardened, into crude ingots called pigs, and the pigs are subsequently remelted along with scrap and alloying elements in cupola furnaces and recast into molds for producing a variety of products.
What is soundness of casting?
Soundness: Measure of impurities and/or discontinuities such as sand inclusions, slag inclusions, macro porosity (pores greater than 50 nm in diameter) and shrinkage.
What is SGI material?
S G Iron is also known as Spheroidal Graphite Iron, Ductile Cast Iron, Nodular Cast Iron, Spherulitic Graphite Cast Iron. S G Iron is a type of cast iron that has been treated while molten with an element such as magnesium or cerium to induce the formation of free graphite as nodules or spherulites.
How many types of castings are there?
This technique includes at least four different methods: permanent, die, centrifugal, and continuous casting. This form of casting also results in improved repeatability in parts produced and delivers near net shape results.
Where are cast iron manufactured?
The cast-iron is manufactured by re-melting pig-iron with coke and limestone. This re-melting is done in a furnace known as the cupola furnace.
How do you test casting?
Nondestructive Testing
- Magnetize the casting to be inspected.
- Apply an inspection medium of fine iron particles while the casting is magnetized.
- Inspect the casting surface for any flux leakage fields.
- Clean the casting of any inspection residue and demagnetize.
How do you find the porosity of castings?
The most common way to check for porosity is an X-ray of the material, using computerized tomography or by cutting and polishing a section and then analyzing it under a microscope.
