Introduction
I. INTRODUCTION
A furnace is an equipment used to melt metals for casting or to heat materials to change their shape during the processing of the product or to enhance properties of the processed components. Electric furnaces are used where more accurate temperature control and relatively cleanliness is required. Melting furnaces are employed to overheat solid materials until they become liquefied.

A robotic arm for an electrical furnace is a specialized robotic system designed to handle tasks related to operating and maintaining electrical furnaces. They will be programmed to perform tasks such as loading and unloading materials, manipulating objects within the furnace, and monitoring temperature or other parameters. Robots can move about in the environment and take the place of humans in dangerous environments or manufacturing processes, or resemble humans in appearance, behaviour, or cognition. With the help of sensors, robots can manage to avoid obstacles on their paths and achieve their goals with or without prior planning, depending on the complexity of their implemented program.

An Electrical furnace is that generates heat by electric current. In these furnaces, gold, silver, brass, copper, and other metals are melted. In 4 comparisons to most other methods of metal melting, the electrical furnace provides a clean, energy-efficient, and well-controlled melting process. Heat-treating mild steel at temperatures ranging from 35 to 1200 for 2000 seconds was used to determine the performance of the Electric heat treatment furnace. The furnace's temperature was sustained at 1200 degrees for over 2000 seconds, showing that the furnace was meant to attain that temperature.
