Steel Melting Furnace Types

In steel melting induction furnaces the steel is charged into a crucible that s surrounded by an electromagnet made of coiled copper.

Steel melting furnace types. To melt the metal in the furnace workers add layers of metal such as ferro alloys limestone and coke. The limestone reacts with the metal making the impurities float up to the surface of the melting metal. Pot furnaces with recuperative air preheating in steel recuperators. 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 pot furnace is usually designed for 1 or 2 pots. The average induction furnace is capable of producing 65 tons of steel at each charge. Induction furnaces are commonly used in foundries because they re high quality and simple to operate. The insides of these furnaces are lined with clay blocks or bricks which protect the furnace s interior from heat abrasion and oxidation.

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. Efforts are made to explain how they work. Chapter 4 critically looks into the different types of old and modern melting methods for iron and steel. 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.

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. Besides that induction furnaces are preferable for melting an array of metals including steel iron aluminum and. 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.

It is crucial that you know the type and functionality of the furnace used in casting your steel. 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. The electric furnace used for melting metals makes the process energy efficient when compared to other types of melting furnaces. The heart of every foundry business is a melting furnace bubbling with hot fluid metal.

Fossil fuel heating principle. Electricity propane or natural gas are usually used to achieve these temperatures. Most of the global foundries use induction furnace instead of the cupola to melt brass or cast iron. These include kgps aluminum shell induction melting furnace kgps steel shell induction melting furnace igbt induction melting furnace and so on.
