Introduction of the Muffle Furnace with Gas Inlet:

The KSL-1700X-A2 is a high-temperature small box furnace. Muffle furnace with gas inlet uses silicon-molybdenum rods as heating elements. The small box furnace features a double-shell structure, PID programmable temperature control, a B-type thermocouple, and a furnace chamber made of high-purity alumina fiber. Electric muffle furnace can reach a maximum temperature of 1700°C and a continuous operating temperature of 1600°C with a temperature control accuracy of ±1°C. The small box furnace offers advantages such as uniform temperature distribution, low surface temperature, and energy efficiency. It is ideal for high-temperature sintering, metal annealing, and quality inspection in universities, research institutes, and industrial and mining enterprises.

Introduction of Silicon Carbide Rod:

Silicon carbide (SiC) heating elements are made from green, high-purity hexagonal silicon carbide. They are manufactured through high-temperature siliconization and recrystallization at 2200°C. They are rod-shaped, non-metallic, high-temperature heating elements. They can operate at temperatures up to 1450°C and, under reasonable conditions, can last for over 2000 hours in air, without the need for a protective atmosphere. Compared to metal heating elements, these elements offer advantages such as high operating temperatures, oxidation and corrosion resistance, long life, minimal deformation, and easy installation and maintenance. Therefore, they are widely used in a variety of high-temperature furnaces and other heating equipment in industries such as electronics, magnetic materials, powder metallurgy, ceramics, glass, metallurgy, and machinery.
