Weight of Iron Ingot
An iron ingot is a bar of iron that has been melted and cast into a solid form. This type of iron is commonly used in the steel industry, and can be purchased from companies that manufacture iron.
Ingots are typically stamped with a mark indicating the purity of the iron, which is useful for determining how the metal should be handled. They may also be stamped with a logo or other information to indicate where the metal was made and by whom.
In general, iron is a soft metal that can easily oxidize and absorb oxygen from the air; however, when it is mixed with carbon to create an alloy, it becomes strong and hard. The specific gravity of most iron is around 1.9, but it can vary depending on the grade and the amount of carbon added to it.
Phosphorus in Cast-iron:
It is generally known that the presence of phosphorus in cast-iron has a weakening effect on the metal and increases its brittleness. This makes it necessary to keep down the phosphorus percentage in the casting iron used for ingot moulds.
It has been found that some ingot moulds are subject to the phenomenon of broken feet. This occurs when pieces of material break away from the inside of the mould foot during stripping. This causes the average life-span of these ingot moulds to be shortened considerably.
The present invention aims to counteract the problem of broken feet in ingot moulds. The method involves casting a cast-iron ingot mould from a cast iron having a composition (by weight): wherein the Si-content is smaller than the Mn-content, and wherein the phosphorus percentage is reduced by about 0.06 %.
