As we have seen earlier, the casting is done using investment casting as it is used in different places.Different metals are used in different places depending on usage. There is a ferrous or non ferrous metal.
So today I will show you some formulas related to how to prepare some standard metal in investment casting. Although this topic is a metallurgical, but I also know a little about this subject.

In investment casting, the ferrous and non-ferrous metals and their alloy metal are made of their row material. If foundry works with a standard company, it is a working pad as per the standard of the metal standard.
Different countries have their own standards. But the analogy is found in the chemical composition of the metal's grade. The most common is the ASTM standard. Because the ASTM standard has covered all grades of steel.

ASTM standard is also provided in the pet type, such as
1)Analytical Chemistry Standards: cover the chemical analysis of various metals, alloys, and ores and it describe and specify certain instruments and equipment that must be used for chemical analysis.
2)Fastener Standards: it use for some general physical properties like mechanical, and metallurgical properties
3) Fatigue and Fracture Standards: provide procedures for carrying out fracture, fatigue, and other tests.
4)Nonferrous Metal and Alloy Standards provide other evaluation procedures to assess and identify compositions, dimensions, nomenclature, properties, analysis, classification
5)Metallic Coating Standards: it help to identify characteristics of material such as compressibility , tensile, density, stength, etc.

So now come to the topic that how to prepare the metal. The erosion of metal in investment castings is melted at 1500 to 1800 degrees in furnace. At the same time, dewaxing ceramic cells are preheated.
The preheating temperature of the cell is approximately 900 to 1100 degrees. Generally speaking, for preheating, Generally speaking, for preheating, when the molten metal is at high temperatures, it does not come from the speed to low temperatures, so that does not hit the speed. And if this is not done then normal ceramic cell can not bear the temperature of molten metal and it breaks. When the metals are melting and ready, samples of their chemical elements are analyzed.
The machine used for this is called a spectrometer. there are mainly 8 elements are analyzed such as Carbon, Silicon, Manganese, Phosphorus, Sulfur, Nickle, Chromium, Molybdenum. The test shows that the Q element is in the ratio.
The metal is made proportionally by adding elements of the elements according to the given excel sheet.

1) In this sheet you have to first decide the size of ferns in kg
set value in cell E2
2) Determine what metal should be cast
set value in cell F2 from D35 to D41
it automatically detect chemical composition of given material according to ASTM standard in RED portion
If you write WCB in F2, something will come in such a way
3)Now, input your spectro analysis result in raw in raw 9
it gives total kilogram of composition of your total kg in raw 10
4)Add some composition in raw 13
Now when you add a composition into metal preparation, there will be a lot of impact on the remaining composition.
5)you can see a result of metal in raw 16 to 25 in form of percentage in kg also.
