B. Product introduction
The introduction of foreign technology, independent research and development and production, energy-saving, new electric furnace. It has a reasonable double-layer shell structure, the surface temperature is less than or equal to 40 ℃, and the appearance is beautiful and generous. It is processed by cold-rolled steel plate, CNC machine tools, high-precision laser cutting machines, and CNC bending machines. The surface is beautiful, luxurious, and two-color. The oxidized powder is electrostatically sprayed to achieve a durable, non-fading, high-temperature and corrosion-resistant surface treatment.
Heating element: Choose different heating elements according to the furnace temperature. Heating elements are divided into: electric furnace wire, resistance band, silicon carbide rod, silicon molybdenum rod, and molybdenum wire.
Liner material: The liner is made of imported temperature refractory materials and constructed by the craftsmanship. Strong thermal shock resistance, good corrosion resistance, no collapse, no crystallization, no slag, and long service life!
The two ends of the furnace tube are sealed with stainless steel flanges, which can work under vacuum. The flanges are equipped with air inlets and outlets for the introduction of protective gas. The stainless steel flanges are designed with quick opening for easy access to materials.
