Steel Melting Furnace Types

Fossil fuel heating principle.

Steel melting furnace types.

These large furnaces can hold up to 400 tons when melting steel which is often made of heavy iron like slabs pig iron and recycling of things like car scraps. In steel melting induction furnaces the steel is charged into a crucible that s surrounded by an electromagnet made of coiled copper. Each pot is located in a separate combustion space zone and specific relatively different thermal conditions can be created in each zone even in a two zone type pot furnace. Electricity propane or natural gas are usually used to achieve these temperatures.

Efforts are made to explain how they work. These include kgps aluminum shell induction melting furnace kgps steel shell induction melting furnace igbt induction melting furnace and so on. Once all the components are melted the whole furnace is tilted discharging the liquid metal to a ladle which can sometimes be smaller furnaces that can keep the metal hot before casting. The electric furnace used for melting metals makes the process energy efficient when compared to other types of melting furnaces.

The average induction furnace is capable of producing 65 tons of steel at each charge. For high melting point alloys such as steel or nickel based alloys the furnace must be designed for temperatures over 1 600 c 2 910 f. Pot furnaces with recuperative air preheating in steel recuperators. The advantage of the induction furnace is a clean energy efficient and well controllable melting process compared to most.

Induction furnaces are commonly used in foundries because they re high quality and simple to operate. The limestone reacts with the metal making the impurities float up to the surface of the melting metal. Furnace systems for the carbon steel industry moving ahead with experience and innovation on account of its long tradition and experience andritz maerz a company belonging to the business area metals is one of the leading suppliers of engineering know how and process technology to the reheating heat treatment melting and refining of. Chapter 4 critically looks into the different types of old and modern melting methods for iron and steel.

Induction furnace capacities range from less than one kilogram to one hundred tonnes and are used to melt iron and steel copper aluminum and precious metals. The pot furnace is usually designed for 1 or 2 pots. An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. For low temperature melting point alloys such as zinc or tin melting furnaces may reach around 500 c 932 f.

To melt the metal in the furnace workers add layers of metal such as ferro alloys limestone and coke. Besides that induction furnaces are preferable for melting an array of metals including steel iron aluminum and. Most of the global foundries use induction furnace instead of the cupola to melt brass or cast iron. The furnaces apply various technologies that mold the metal alloy and additives into specific grades of steel.
