Introduction
Converting electrical energy into thermal energy to heat objects. It is a form of electrical energy utilization. Compared with general fuel heating, electric heating can achieve higher temperatures (e.g., arc heating can reach temperatures above 3000°C), and it is easy to realize automatic temperature control and remote control, vehicle-mounted electric heating cup
The heated object can be maintained at a certain temperature distribution as needed. Electric heating can generate heat directly inside the heated object, thus having high thermal efficiency and fast heating speed. According to the heating process requirements, it can achieve uniform heating or local heating (including surface heating) of the whole object, and it is easy to realize vacuum heating and controlled atmosphere heating. During the electric heating process, less waste gas, residue, and smoke are produced, keeping the heated object clean and not polluting the environment. Therefore, electric heating is widely used in production, scientific research, and experiments. Especially in the manufacturing of single crystals and transistors, mechanical parts and surface quenching, smelting of ferroalloys, and artificial
