Application scope and precautions of industrial electric furnace

As an advanced heating equipment, industrial electric furnace plays a very important role in modern industrial production. It uses electrical energy to convert into thermal energy, which can achieve uniform and precise heating of workpieces. It is widely used in many fields such as metal smelting, glass manufacturing, and ceramic firing. In this article, the editor of Hut Instrument mainly introduces the application scope and precautions of industrial electric furnaces.

1. Application scope of industrial electric furnaces

Metal smelting industry

In the fields of metal smelting such as steel and non-ferrous metals, electric furnaces are important smelting and heating equipment. Electric arc furnaces, induction furnaces, etc. can be used for metal melting, refining, insulation and other links to ensure that the temperature of the metal liquid meets the process requirements. Compared with traditional fuel heating, electric furnace heating is cleaner and more environmentally friendly, has lower energy consumption and precise control.

Glass manufacturing and ceramic firing

The manufacture of glass is inseparable from high-temperature melting and forming processes. Special resistance furnaces, electric arc furnaces and various types of tubular electric furnaces are ideal heating devices for glass melting furnaces, which can provide a stable and uniform high-temperature environment for glass melting and pouring.

The shaped ceramic body needs to be fired at high temperature to improve its strength and durability. Large industrial electric furnaces such as tunnel kilns and tank kilns are suitable for this process, which can accurately control the temperature curve and obtain excellent firing effects.

Heat treatment industry

The metal heat treatment process requires temperature-controlled heating, heat preservation and cooling of the workpiece. Various types of industrial electric furnaces such as box-type resistance furnaces, lathe furnaces, annealing furnaces, etc. can meet the needs of heat treatment production lines.

Chemical industry

In the chemical process, raw materials or intermediate products often need to be treated at high temperatures. Industrial electric furnaces can provide the required heat for many thermal reactions, such as electrolysis, polymerization, and roasting. At the same time, some electric furnaces can also be used to prepare functional materials such as special glass fibers.

2. Precautions for the application of industrial electric furnaces

Strictly implement the operating procedures: Operators should strictly follow the instructions for use and comply with various safety operating procedures. Such as correctly setting the temperature, maintaining good furnace airtightness, timely inspection and maintenance, etc., to avoid accidents caused by operating errors.

Pay attention to the management of auxiliary systems: The operation of the electric furnace requires the coordinated operation of multiple auxiliary systems, such as the power supply system, exhaust system, cooling system, etc. The status of these systems directly affects the performance of the electric furnace. Regular maintenance is required to ensure that all systems are in good condition.

Strengthen protection against high temperatures: During the high-temperature operation of the electric furnace, the operator and the surrounding environment will be affected by certain radiation, and effective protective measures must be taken. For example, setting up protective barriers, equipping with thermal insulation workwear, etc., to minimize the harm of high temperature to people and equipment.

Pay attention to energy conservation and emission reduction management: The energy consumption of electric furnaces is high, and a variety of energy-saving measures should be taken, such as selecting new insulation materials, optimizing control parameters, etc., to reduce production costs. At the same time, we must actively adopt environmental protection measures to reduce the impact of waste gas, smoke and other byproducts on the environment.

In short, the application of industrial electric furnaces plays an important role in realizing industrial automation and green development today. At the same time, we must also attach great importance to the safety and energy conservation and environmental protection issues during the operation of electric furnaces, do a good job in comprehensive management and control, and give full play to the application value of electric furnaces.
