AJ-SS Series High-Temperature Precision Box-Type Electric Furnace integrates the control system and furnace chamber into one unit. The furnace lining is made of imported high-purity vacuum-formed alumina fiber lightweight aggregate board.
Heated by resistance wires or molybdenum disilicide rods, it is a specialized equipment developed for laboratories of colleges and universities, scientific research institutes, as well as industrial and mining enterprises. It is designed for the sintering, melting, analysis, and production of ceramics, metallurgical, electronic, glass, chemical, mechanical, refractory materials, new material development, special materials, building materials, metals, non-metals, and other compound materials.
The control panel is equipped with an intelligent temperature controller, control power switch, main heating start/stop buttons, voltage and current meters, and computer interface for real-time monitoring of the system's operating status. Adopting reliable integrated circuits, the product ensures a stable working environment and strong anti-interference capability. When operating at the maximum temperature, the furnace shell temperature is ≤ ambient temperature + 25℃, which significantly improves the working environment. Featuring microcomputer program control and programmable temperature curves, it enables automatic heating and cooling. Temperature control parameters and programs can be modified during operation, offering flexibility, convenience, and ease of use.
