A melting furnace is a device that has the ability to generate the heat that is needed to melt a certain weight of metal or alloy with the required speed and acceptable costs. The choice of furnace is determined by cost, metal quality, production needs and type of alloy. The versatility of the furnace in different conditions is an advantage for different types of production.
Types of melting furnaces
Based on their application, furnaces are categorized into three groups of ; reheating / melting / holding furnaces. In terms of energy consumption, they are divided in two main categories ; [fossil fuel furnaces / electric furnaces ]
