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.

High temperature laboratory furnaces are easy to operate: equipped with a clear control panel (knobs, buttons, or touchscreen), and some models support PLC control. Multiple safety features: Overtemperature alarm and power-off protection: Automatically alarms and shuts off the heating power when the temperature exceeds the set value;

Sandpaper is not recommended for routine cleaning of tube and box furnaces, as it may scratch the furnace surface, affecting performance and lifespan. The correct cleaning method involves using a soft cloth or sponge with a dedicated cleaning agent.

​The "4th National Refractory Metals and Hard Alloys Technology Symposium" was successfully held in Zhuzhou, Hunan Province from August 15-17, 2025. The conference, jointly organized by several research institutions and universities, focused on various refractory metals and hard alloys, including tungsten, molybdenum, tantalum, and niobium. The discussions covered their applications in high-temperature alloy steel, hard alloys, semiconductors, magnetic materials, and other fields, with a focus on key technologies such as grain refinement and new material development. With the core objective of "strengthening information exchange and addressing industry hotspots and challenges," the conference aimed to promote technological progress, help solve current industry issues, and facilitate high-quality development and industry-academia collaboration.

1. Understand the temperature tolerance range of the material. Different materials have different high-temperature resistance properties. Excessively high temperatures can cause deformation, melting, or damage. Therefore, when setting the temperature of a high-temperature box furnace, you should refer to the material's temperature tolerance range to ensure that the selected temperature does not exceed this range.

From August 13th to 15th, the "15th Symposium on Inorganic Nonmetallic Materials and the Forum for Outstanding Scholars in Inorganic Nonmetallic Materials," hosted by the Chinese Ceramic Society, was successfully held in Harbin. Guests from the Chinese Ceramic Society and the National Natural Science Foundation of China, as well as over 1400 experts and scholars, including several academicians from the Chinese Academy of Sciences and the Chinese Academy of Engineering, attended the conference.
