Vertical opening and closing tube furnace KJ-K12

main purpose

Tube furnace is mainly used for the heat treatment of samples in laboratories under vacuum or protective atmosphere. It is used for powder roasting, ceramic sintering, high-temperature experiments, material processing, high-temperature atmosphere sintering, atmosphere reduction, CVD experiments, vacuum annealing, etc. in ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractory materials, special materials, building materials, universities, research institutes, and industrial and mining enterprises

Product Introduction

Introducing foreign technology and independently developing and producing energy-saving and new electric furnaces. It has a reasonable double-layer shell structure, with a surface temperature of less than or equal to 40 ℃, and a beautiful and elegant appearance. It is processed using cold-rolled steel plates, CNC machine tools, high-precision laser cutting machines, and CNC bending machines. The surface is made of beautiful and luxurious dual color oxide powder for electrostatic spraying, achieving long-lasting, non fading, high temperature resistance, and corrosion resistance surface treatment.

Heating element: Different heating elements are selected according to the furnace temperature. Heating elements are divided into: electric furnace wire, resistance strip, silicon carbon rod, silicon molybdenum rod, and molybdenum wire.

Inner liner material: The inner liner is made of imported high-temperature refractory materials and constructed through advanced technology. Strong thermal shock resistance, good corrosion resistance, no collapse, no crystallization, no slag falling, and long service life!

The two ends of the furnace tube are sealed with stainless steel flanges, which can work under vacuum. There are inlet and outlet ports on the flange, which can be used to introduce protective gas. The stainless steel flange has a quick opening design, which facilitates the entry and exit of materials

Product Features
