This gives small box furnace a certain advantage in some applications with strict temperature requirements, such as annealing of high melting point metals.

Our small box furnace uses a double-shell structure, with PID programmable temperature control and type B thermocouple, the temperature control accuracy can reach ±1°C.

In material processing and scientific research experiments, metal heating treatment is widely needed, and many people will ask: Can muffle furnaces melt metal?Taking Shenyang Kejing KSL-1700X-S industrial muffle furnace as an example, the answer is-under certain conditions, this industrial muffle furnace can melt part of the metal, and it shows certain advantages in the field of metal high temperature treatment.

In the field of industrial heating and scientific research experiments, muffle furnaces are common equipment, but many people will be curious: What is the nickname of muffle furnaces? In fact, according to application scenarios, structural characteristics and functional differences, muffle furnaces have multiple commonly used nicknames, and in industrial production scenarios, these nicknames are mostly closely related to the actual use of industrial muffle furnace.​

Muffle furnace is a heating electric furnace, which is often used as a heating equipment in the heat processing, analytical chemistry and other industries.

1. Before using the tube furnace, install the insulation plugs. Position the insulation plugs as shown in the diagram. Pull them outwards as needed, but ensure they are symmetrical on both sides to prevent damage to the furnace chamber.

​The 26th China International Optoelectronic Exposition (CIOE 2025), a three-day event, successfully concluded on September 12th! This year's exhibition attracted a record number of participants, with over 3800 high-quality optoelectronic companies from around the world gathering at the event. Eight themed exhibitions focused on core areas such as information communication, precision optics, camera technology and applications, lasers and intelligent manufacturing, infrared & ultraviolet, intelligent sensing, new displays, AR&VR, and optoelectronic innovation, successfully building a comprehensive optoelectronic industry ecosystem. The exhibition floor was bustling with activity, showcasing a wide array of cutting-edge technologies and innovative products, providing a visual and technological feast for the optoelectronic industry.

1. Do not place the unit on an uneven or vibrating surface, as this may cause the unit to become unstable and tip over. 2. Do not place flammable or explosive items near the furnace, as this may cause an explosion. 3. Do not drop metal objects such as screws and washers into the unit, as this may cause a short circuit or fire. 4. Do not place the unit in a location susceptible to water splashing. If water enters the unit, it may cause a fire or electric shock.

During operation, a high temperature box furnace may experience abnormal furnace pressure, seriously affecting normal operation. Symptoms of abnormal furnace pressure include unstable combustion, a smaller or larger flame, and increased noise. There are many causes, and this article describes some common solutions.
