Vacuum atmosphere furnace KJ-QL18

main purpose

This equipment is widely used in universities, research institutes, and industrial and mining enterprises for high-temperature sintering, metal annealing, chemical, metallurgical, ceramic, new material development, organic matter ashing, quality testing, and is also suitable for production and experimentation in military, electronics, medicine, special materials, and other industries.

Product Introduction

The high temperature atmosphere furnace series is a horizontal vacuum atmosphere box furnace, also known as an oxygen free annealing furnace or a vacuum atmosphere sintering furnace, specially designed for sintering materials in a vacuum state with an atmosphere (such as inert gas, etc.) environment. The high temperature can reach 1800 ℃Introducing foreign technology and independently developing and producing energy-saving and new electric furnaces. Having a reasonable double-layer shell structure, with a surface temperature of less than or equal to 40℃The appearance is beautiful and elegant, processed from 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!

Temperature control method: microcomputer intelligent regulation technology, PID regulation, fully automatic control, self-tuning function; Multi segment programming and the ability to control various heating, insulation, and cooling programs; Power regulation; High temperature control accuracy; Integrated module thyristor control, phase shift triggering. Protection device: independent over temperature protection, over voltage, over current, leakage, short circuit protection, etc., with a high degree of automation and various indicators reaching the level.

Product Features

1The furnace body adopts a double-layer furnace shell structure, which is processed from 10mm steel plate and has a carbon steel shell. It is welded by the pressure vessel factory to ensure the airtightness of the weld seam, without any air leakage points such as sand holes or broken lines. It is reliable and meets various national standards for protective design, with good performance.

2The heating element adopts high-temperature heating elements, which can withstand high loads, are stable, and have a long service life. To ensure use, a fully copper isolated transformer is used

3The heating rate is fast, and it usually takes 60-90 minutes to reach 1600 degrees Celsius from room temperature

4High temperature control accuracy, low temperature flushing, with temperature compensation and correction functions, with an accuracy of ± 1 ℃

5Adopting imported temperature control instruments with program functions, it can set the heating curve and program 2 sets of 16 segments

6Integrated structure, reducing usage space, excellent appearance design, beautiful and generous

7All electronic components are made of manufacturer's products with leakage protection function, which is reliable

8This machine will issue an alarm signal for overheating during operation and automatically complete protection actions

9It can be filled with other inert gases such as hydrogen, argon, nitrogen, etc., and can be pre evacuated with a vacuum degree of up to -0.1MPa,(Customization available for 1Pa, -1Pa, -0.01Pa, etc.)Glass rotor flowmeter and inlet/outlet pipelines, etc

10The furnace door is a side opening method, and the furnace door and top are sealed by stainless steel extrusion from left to right. The furnace door and furnace backup circulating water cooling system have air inlet, air outlet, and vacuum outlet on the furnace body.

11According to the requirements, a double-layer water-cooled furnace shell is made to protect and seal the silicone gasket while assisting in accelerating the cooling speed.

12The furnace door is sealed with a 20mm thick wire cut flange, embedded with an O-ring, and locked with a stainless steel handwheel.

13Optional large screen paperless recorder to achieve real-time recording of temperature rise curves, with storage card for analysis and printing of experimental data
