Steel Melting Furnace Types

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.

Steel melting furnace types.

Pot furnaces with recuperative air preheating in steel recuperators. 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. 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. The electric furnace used for melting metals makes the process energy efficient when compared to other types of melting furnaces.

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. It is crucial that you know the type and functionality of the furnace used in casting your steel. The advantage of the induction furnace is a clean energy efficient and well controllable melting process compared to most. 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.

Most of the global foundries use induction furnace instead of the cupola to melt brass or cast iron. Efforts are made to explain how they work. For low temperature melting point alloys such as zinc or tin melting furnaces may reach around 500 c 932 f. These include kgps aluminum shell induction melting furnace kgps steel shell induction melting furnace igbt induction melting furnace and so on.

Induction furnaces are commonly used in foundries because they re high quality and simple to operate. The furnaces apply various technologies that mold the metal alloy and additives into specific grades of steel. The pot furnace is usually designed for 1 or 2 pots. The heart of every foundry business is a melting furnace bubbling with hot fluid metal.

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. To melt the metal in the furnace workers add layers of metal such as ferro alloys limestone and coke. Fossil fuel heating principle. An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal.

The insides of these furnaces are lined with clay blocks or bricks which protect the furnace s interior from heat abrasion and oxidation. Besides that induction furnaces are preferable for melting an array of metals including steel iron aluminum and. In steel melting induction furnaces the steel is charged into a crucible that s surrounded by an electromagnet made of coiled copper. Chapter 4 critically looks into the different types of old and modern melting methods for iron and steel.
