Box-type Electric Furnace

In the core scenarios of industrial production and scientific research experiments, the Guanding Box-type Electric Furnace, as an indispensable high-temperature heating equipment, its high-temperature resistance, inner tank material and thermal insulation performance directly determine process accuracy and production efficiency. It is also a key consideration for purchasers from industrial enterprises, scientific research institutes and university laboratories. Shanghai Guanding Industrial Equipment Co., Ltd. has long been engaged in the field of industrial heating equipment. The Guanding Box-type Electric Furnace, crafted with rigid industrial quality, meets the high-temperature process requirements of multiple industries in strict compliance with industry standards, and has become the preferred box-type electric furnace for purchasers and researchers.

High-temperature resistance is the core competitiveness of the Guanding Box-type Electric Furnace. With scientific industrial structural design and high-quality high-temperature resistant materials, the Guanding Box-type Electric Furnace achieves stable full-range high-temperature resistance, covering both conventional working conditions and special high-temperature requirements. Depending on the equipment model, the Guanding Box-type Electric Furnace can achieve precise temperature control from 500℃ to 1800℃. Specifically, the standard model is suitable for low-temperature working conditions of 500℃-1200℃, the high-temperature model can operate stably at 1200℃-1600℃, and the ultra-high temperature model can even reach the extreme high-temperature environment of 1600℃-1800℃. It can meet the differentiated high-temperature needs of various industries, completely addressing the pain points of traditional box-type electric furnaces such as easy damage at high temperatures and unstable operation. Even under long-term high-temperature load, it can still maintain stable heating performance, demonstrating the durability and reliability of the industrial-grade Guanding Box-type Electric Furnace. This full-range high-temperature resistant design is developed in strict accordance with the "Basic Technical Conditions for Electric Heating Devices - Part 44: Box-type Resistance Furnace" (GB/T 10067.44-2014) to ensure the standardization and safety of the Guanding Box-type Electric Furnace during operation.

As the core component of the Guanding Box-type Electric Furnace that directly contacts high temperatures, the selection of inner tank material directly affects the high-temperature resistance and service life of the furnace. According to different temperature levels and application scenarios, the Guanding Box-type Electric Furnace adopts differentiated high-quality inner tank materials, balancing high-temperature resistance, corrosion resistance and practicality. The low-temperature model (≤1200℃) is equipped with a refractory ceramic fiber inner tank, which is lightweight and boasts excellent high-temperature resistance, suitable for conventional laboratory processes such as ashing and low-temperature sintering. The medium-high temperature model (1200℃-1600℃) uses a corundum ceramic (alumina) inner tank, which can withstand temperatures up to 1700℃, with high hardness and strong wear resistance, ideal for ceramic powder sintering, metal annealing and other processes. The ultra-high temperature model (≥1600℃) adopts a mullite-corundum composite ceramic inner tank, capable of withstanding temperatures up to 1800℃, suitable for high-end scientific research and industrial scenarios such as special ceramic melting and crystal growth. It fundamentally ensures the high-temperature stability and service life of the Guanding Box-type Electric Furnace, avoiding disruptions to process progress and experimental results caused by inner tank damage.

Excellent thermal insulation performance is key to energy conservation, consumption reduction and precise temperature control of the Guanding Box-type Electric Furnace. The Guanding Box-type Electric Furnace adopts a multi-layer composite thermal insulation structure to create an efficient thermal insulation system, balancing energy conservation and temperature control accuracy—one of its core advantages over traditional box-type electric furnaces. The equipment's thermal insulation layer adopts a layered design: the medium-low temperature model uses ceramic fiber cotton/board as the core thermal insulation material, which is lightweight and offers outstanding thermal insulation, effectively reducing high-temperature heat loss. The ultra-high temperature model adopts a composite structure with high-purity alumina fiber in the inner layer and mullite fiber in the outer layer to further enhance thermal insulation performance. Meanwhile, it is equipped with a sealed furnace door design and a silica gel/graphite sealing ring to minimize heat leakage, ensuring uniform and stable temperature inside the furnace chamber. The surface temperature of the furnace body is strictly controlled below 60℃, which not only prevents operator scalds but also reduces energy consumption, meeting the environmental protection and energy-saving requirements of production and experiments. It solves the problems of poor thermal insulation, high energy consumption and uneven internal temperature in traditional box-type electric furnaces, providing a guarantee for process accuracy.

With its flexible performance, the Guanding Box-type Electric Furnace is widely applicable to multiple fields including industrial production, scientific research experiments and university teaching, covering a variety of core high-temperature processes and meeting the personalized needs of different users for box-type electric furnaces.
