melting loss very in all castings from 2% to 50%.
If you melt aluminum pure ingots & cast within minimum holding loss is 2%. If you cast in small batches it will go up to 15%.
If you melt aluminum scrap & cast within minimum holding loss is 15%. If you cast in small batches it will go up to 30%
If you melt aluminum turnings & cast within minimum holding loss is 25%. If you cast in small batches it will go up to 50%
melting loss very in all castings from 2% to 50%.

Why safety is a must in an industry?
Safety is a must in all type of industries to prevent accidents, incidents and ill health there by reducing the cost associated with accidents and incidents such as property damage, manpower loss, time loss, insurance premiums, loss of reputation etc.
What is the need for inspection of goods?
Good need to be inspected to avoid Business profit loss in Damage or expired product and even law sued. this may cause business to loss its export and import liabilities and other business will not buy any products from them and also loss their trust.
What is formula for boiler efficiency?
boiler efficiency calculation methods:Input-output methodη = Output / Input Output is defined as the heat that is absorbed by working fluid. Input is defined as the chemical heat of fuel plus the heat that is added to working fluid, air, gas and other fluid circuit in which the fluid circuit across thin layer.Heat Loss MethodHeat loss method is the method that is used to calculate the percentage amount of heat which is not useful. This method is very effective used in an attempt to find potential savings of boiler with heat balance. There are several factors act as the source of heat loss combustion. These factors will be used to calculate boiler efficiency based on heat loss method. The source of heat loss can be seen as following below:a. Heat loss due to dry flue gasHeat loss due to dry flue gas is the heat loss which is contained in dry flue gas such as CO2, O2 and N2. These gases are one of causes of heat loss in combustion process. The high temperature of flue gas coming out from boiler affect amount of heat loss.The weight and heat loss of dry flue gas of combustion of coal can be calculated as following formula:Wdfg = mCO2 + mSO2 + mO2 + mN2Eloss dfg = Wdfg x Cp x (To - Ts)Where:Wdfg = weight of dry flue gas (kg/kg coal)Eloss dfg = heat loss in dry flue gas (kJ/kg)To = temperature of dry flue gas coming out from boilerTs = temperature of surroundingby Gajanan Nalegaonkar
If the amount of loss in a manufacturing process is abnormal is it classified as a period cost?
Yes and charged to a separate account, such as Loss from abnormal Spoilage, and are shown as a separate item of expense on the current income. These losses do not become a part of the manufacturing costs trasferred to finished goods and cost of goods sold.
What is the ratio of rust to steel loss?
The ratio of rust to steel loss can vary significantly based on factors such as environmental conditions, the type of steel, and the duration of exposure to moisture and oxygen. Generally, for every 1% of steel lost to rust, it is estimated that around 10-20% of the volume of rust is generated, due to the oxidation process. However, this ratio can fluctuate, and specific assessments are needed for precise calculations in different scenarios.
How does silver separate from other metals when you melt it down?
It has a different melting point from the other metals. For example, the melting point of copper is about 200 degrees F higher than silver. So if you were to heat the object to approximately 1750 degrees F (estimate, look up the exact melting point before attempting), the silver will melt off of the copper. Do not attempt this, as it is quite dangerous. I am in no way responsible for any injury or loss incurred while attempting anything mentioned in my post.
Why do all the alkaline earth metals have similar properties?
All alkaline earth metals loss two electrons.

YES the Arctic has seen ice loss.
What is the melting loss for gold in Percentage?
Gold has a very low melting loss percentage, typically less than 1%. This is one of the reasons why gold is considered a valuable and sought-after metal for jewelry and investment purposes.
When nonmetals and metals react which atom electrons?
Metals loss electrons and nonmetals gain electrons.
What is the melting loss of steel in a cupola furnace?
First of all to correct that Cupola Furnace is used to melt Pig Iron to make Cast Iron not the Steel. As per practice the melting loss in Cupola furnace is cosiderd as arround 4.00 %. Sirajuddin Khan Bolan Castings Ltd. Karachi, Pakistan
Why property makes the alkali metals very reactive?
The alkali metals have a low electronegativity and they easily loss an electron.
What is the melting loss of steel in an induction furnace?
There is hardly 1.5 to 2.0% loss in induction melting of steel but even it can be also avoided with the help of covering of crucibles. just open it at the time of charging only is the best practise to avoid oxidation & heat losses for Induction melting for steel.
