What is difference between Cupola furnace and blast furnace?
In essence nothing, a Cupola furnace is a type of blast furnace in that it is charged at the top and tapped at the bottom and air is blasted into the furnace via a wind belt and tuyres. A blast furnace in a steel works is a huge structure operated for long periods of time, it is charged with iron ore, coke and limestone and reduces the iron ore into pure iron. A Cupola furnace, as used in the foundry re melts pig iron, from the blast furnace, along with foundry scrap, steel scrap and scrap iron engine blocks and produced iron alloys of various specifications. A Cupola furnace is usually operated on a daily basis but some types can be continuously operated for several weeks
What is hms1 and hms2?
HMS1 and HMS2 typically refer to two grades of high melting scrap metal, often used in recycling and metallurgy. HMS1 (Heavy Melting Steel 1) consists of heavier and thicker scrap, such as large industrial items, while HMS2 (Heavy Melting Steel 2) includes lighter scrap like thinner sheets and miscellaneous scrap metals. These classifications help in determining the quality and price of scrap metal in the recycling market.
What is arcing length in steel melting?
Please rephrase the question. Are you describing an electrical furnace or the welding process?
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.
What is the mass of steel when in an arc furnace?
400kg
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

What are the processes involved in steel making?
Iron ore is heated to melting point in a blast furnace. Other elements are added depending on the type of steel required Scrap steel can be melted down in an electric furnace also.
What is a steel mill?
A Mini Mill, i.e. Electric Arch Furnace (EAF) melting shredded steel scrap &/or a combination of Hot Briquetted Iron (HBI) or Direct Reduce Iron (DRI).
What is LMS scrap?
Light Melting Steel
What is pool iron scrap?
Basically it is from Blast furnace where in which liquid steel is made prior to arriving at the other (BOF) Basic Oxygen Furnace, and obviously needs to reach a certain Heat to the pull across. It is waste generated during process of melting of steel (by means of spillage while discharging from blast furnace).
What is a non-Integrated steel mill?
A Mini Mill, i.e. Electric Arch Furnace (EAF) melting shredded steel scrap &/or a combination of Hot Briquetted Iron (HBI) or Direct Reduce Iron (DRI).
What is electricity consumption of induction furnace for steel melting?
500 units per ton to 800 units per ton depending on quality and type of scrap and finish products
What is a scrap crane?
A scrap crane is a crane (mobile or EOT -electric overhead traveling) in a scrap yard most commonly steel scrap. The applicaton I use is a EOT crane with a magnet. It loads steel scrap into a ladle which goes into a electric arc furnace.
What is Integrated steel mill?
An integrated steel mill reduces iron ore with coke in a blast furnace into liquid iron. The liquid iron is then charged with scrap metal into a basic oxygen furnace and turned into steel. Many integrated steel mills have a coking facility on site.
