Box type electric furnace, also known as electric box furnace, is a kind of heating equipment that uses electric energy as the heat source and realizes high-temperature heating treatment in a closed box structure. Different from other types of heating equipment, it has the characteristics of uniform temperature distribution, precise temperature control, safe and stable operation, and wide application range, which makes it an indispensable key equipment in modern industrial production and scientific research activities. Its working principle is based on the electrothermal conversion and temperature control technology: the heating element converts electric energy into heat energy, which is transmitted to the furnace chamber through thermal radiation and thermal conduction, and the temperature control system accurately controls the furnace temperature to maintain it at the set value, so as to meet the different process requirements of various materials processing.

From the perspective of product structure, the rational design of box type electric furnace is the key to ensuring its performance. The furnace body usually adopts a double-layer furnace shell structure, and a fan is installed between the double layers to realize rapid heating and cooling, while effectively reducing the surface temperature of the furnace body, ensuring the safety of the working environment and improving the comfort of operation. The furnace chamber is made of imported Morgan fiber, which has the advantages of high service temperature, small heat storage capacity and good thermal insulation performance. Compared with the old electric furnace, its energy-saving effect can reach more than 80%, which conforms to the global green and low-carbon development trend. The heating element adopts high-purity silicon molybdenum rod, which has excellent high-temperature oxidation resistance. Its surface will form a dense quartz glass film in the oxidation atmosphere, which can effectively prevent the element from oxidation and aging. The resistance of the element does not change with the service time, so new and old elements can be mixed use, which greatly reduces the use cost of enterprises.

In terms of technical performance, the box type electric furnace has obvious advantages in temperature control accuracy and operation flexibility. The temperature control accuracy and constant temperature accuracy can reach ±1℃, and the maximum heating rate can reach 45℃/min, which can quickly reach the set temperature and effectively shorten the production and experimental cycle. The intelligent control system equipped with a 7-inch touch screen supports 51-segment program programming, which can store multiple sets of heat treatment curves. Operators do not need to repeat parameter settings, which greatly improves work efficiency and reduces operation errors. At the same time, the system can modify temperature control parameters and programs during operation, which is flexible and convenient to meet the dynamic adjustment needs of different processes. In addition, the box type electric furnace also has good anti-interference performance, which can work stably in complex industrial environments and ensure the continuity and stability of production and experiments.

The application field of box type electric furnace is extremely wide, covering almost all fields that need high-temperature heating treatment, and it has become an important support for the development of various industries. In the field of material science and engineering, it is widely used in the sintering of ceramic materials, heat treatment of metal materials (such as quenching, annealing, tempering) and preparation of composite materials, providing a stable high-temperature environment for material forming and performance improvement, so as to make materials meet the expected density and strength requirements. In the metallurgy and casting industry, it is used for smelting of metal ores, preparation of alloys and preheating and heat treatment of castings, which can improve the quality and performance of castings and ensure the stability of product quality.

In the field of environmental protection and energy, box type electric furnace can be used for harmless treatment of waste. Through high-temperature incineration, it can reduce environmental pollution and realize resource recycling. At the same time, it can also provide the required high-temperature conditions for the development and utilization of new energy materials such as biomass energy and solar energy, promoting the development of the new energy industry. In the chemical and pharmaceutical industry, it is used for activation of catalysts, synthesis of polymer materials and carrying out high-temperature chemical reactions. The stable high-temperature environment it provides can effectively improve the catalytic efficiency and ensure the smooth progress of chemical reactions. In the field of education and scientific research, it is an important experimental equipment, which is used for experimental teaching in materials science, metallurgy engineering and other fields, as well as scientific experiments such as material synthesis and chemical reaction mechanism research, providing reliable experimental conditions for researchers to explore new scientific phenomena and laws.

With the continuous development of industrial 4.0 and the in-depth promotion of the global "double carbon" strategy, the box type electric furnace industry is also facing new development opportunities and challenges. The future development of box type electric furnace will focus on three directions: intelligence, greenization and high precision. Intelligence is reflected in the deep integration of Internet of Things, big data and AI algorithms, realizing remote monitoring, process optimization and predictive maintenance of equipment, reducing equipment downtime and improving production efficiency. Greenization is mainly reflected in the continuous upgrading of energy-saving technology, the wide application of clean energy and the reduction of carbon emissions, which conforms to the global environmental protection development requirements. High precision is to meet the increasing demand of high-end manufacturing fields such as aerospace for material performance, and realize the precise control of temperature field and atmosphere in the furnace.
